Refractory Castables

Application of Self-flowing Refractory Castable in Kiln Repair

Self-flowing refractory castables are used in narrow parts of the kiln lining, or when repairing damage to various kilns. Self-flowing castables are characterized by high-temperature and hot self-flow pouring.

Self-flowing Refractory Castable

Self-flowing refractory castable material is a kind of refractory castable that has fluidity, filling property and stability, and can rely on self-flow to form a dense lining. In general, the self-flow rate of self-flowing material is controlled between 50% and 100%. If the self-flow value is too small, the material fluidity is poor, and the castable cannot fill the model during construction, forming a dense lining. If the self-flow value is too large, materials may segregate during construction.

Application of Self-flowing Refractory Castable in Kiln Repair

Due to the characteristics of the self-flowing refractory castable, it is convenient to be used for repairing the furnace. In most impressions, the maximum particle size of the self-flowing castable is 5mm. Because this facilitates the flow of the castable. Different types of refractory aggregates used in self-flowing refractory castables have different degrees of self-flowing. It is also based on different temperatures to determine the different materials used for self-flowing castables.

White corundum, brown corundum, alumina-based corundum and high alumina are used as refractory aggregates. When the proportion of various materials and the proportion of water are the same, the self-flow rate of the castable is different. Because the bulk density of the raw materials of self-flowing refractory castables is large, the water absorption rate is low and the impurities are few are the biggest factors of fluidity.

Factors Affecting the Quality of Self-flowing Castables

1. Reasonable aggregate particles and aggregate gradation. Refractory aggregates generally use spherical, low water absorption raw materials, with a particle size of 5-8mm. The ratio of aggregate to powder is 6:4, and the ratio of coarse, medium and fine aggregate is 20:45:30.

2. Suitable binding agent and water reducing agent. Choose reasonable binding agent and water reducing agent.

3. Proper water consumption. Strictly control the water consumption, too much water can reduce viscosity and improve fluidity.

For self-flowing refractory castables, the selection of critical particle size is very important. However, in recent years, with the continuous improvement and research of castable manufacturers, the addition of large particles in the particles has increased the strength of the self-flowing castable. Moreover, the castable flows uniformly and does not sink, which makes the self-flowing castable have a longer service life in repairing the furnace lining.

What is Epoxy Refractory Castable?

Epoxy castables are liquid mixtures made of resin, curing agent, filler, etc. It is a castable made into barrels with resin as binder. This is the first time I have seen this refractory castable.

Epoxy refractory castables work normally at high temperatures and have strong resistance to high and low temperature impacts during the cooling process. High temperature resistant epoxy castables are constantly evolving and improving with the requirements of epoxy cast body insulation. On the one hand, the working environment temperature is relatively high. On the other hand, as insulating parts become smaller and smaller in actual use. Therefore, the requirements for the heat resistance of the cast body are getting higher and higher. Epoxy castables are high-grade refractory castables and are not widely used.

Epoxy Refractory Castable

Important Component Compositionof Epoxy Refractory Castable

Resin is an important part of epoxy castable. The resin plays a stabilizing role and has good electrical insulation properties. It is widely used in composite materials, high-performance adhesives, electrical insulating materials and other fields.

Epoxy castables have good fluidity and less volatile matter at the pouring temperature. Epoxy castables cure quickly and shrink after curing. It is an insulating product integrating insulation, moisture-proof, mildew-proof, anti-corrosion, fixation and isolation.

Silicon powder is also one of the important components of epoxy castables. Silicon powder has an irreplaceable effect on reducing shrinkage, reducing costs, and improving performance. However, if the content of silicon powder is too high, its insulation and mechanical properties will be greatly reduced, which will seriously affect the safe and reliable operation of the power system. If the content of silicon powder is too low, the overall performance will be reduced. Therefore, the proper proportion of castable is very important. Because the amount of this castable is not large, it is necessary to continuously test the amount of addition in the production process to make a suitable epoxy castable.

The production process of epoxy refractory castable is to test out the proportions of filler, silicon powder, resin, and curing agent first, then mix the materials, auto-pressure gel molding, and cure after molding. After the epoxy castable is made, it is added to the mixing tank in proportion. Add fillers of different mass fractions into the mixing tank and add 0.2% accelerator. Stir and defoam for 2 hours at a stirring speed of 30-40°C, so that the epoxy castable can be used.

Refractory Castables

Causes of the Bursting of Refractory Castables for Cement Kilns

In order to improve the operating rate and production efficiency of the rotary kiln, reduce production costs. Most cement manufacturing companies have problems with heavy production tasks and short kiln shut down for maintenance.

Cement Kiln Repair

For cement manufacturers, the time for intermediate and overhaul is generally controlled within 8-15 days. However, cement kilns in my country mostly use low cement series refractory castables based on the hydraulic combination, and their construction, curing, and baking must meet a certain period. Therefore, when the construction period is short and the kiln is fast, the bursting of the castable is prone to occur. In particular, some special bidding castables burst during the baking and feeding of the production line, and the kiln has to be stopped and re-poured, causing unnecessary losses to the enterprise.

Causes of the bursting of refractory castables for cement kilns

There are generally four reasons for the explosion of refractory castables ( used in cement kilns.

First, the production tasks of each cement production enterprise are heavy. A production line with a daily output of 5,000 tons of cement has a daily production value of about 1 million yuan. Therefore, most cement plants need time for maintenance. In order to open the kiln as soon as possible, the curing and baking time of the castable has to be reduced.

The second is that the current refractory castable materials for cement kilns in my country are mainly SiO2 and Al2O3 systems. The binder is fast-hardening and high-strength cement-based on aluminate cement. This requires that the castable has sufficient curing time and a reasonable baking system after the construction is completed, which requires a longer time.

Third, the maintenance of my country’s cement industry is basically entrusted to furnace construction companies. The professional level of the construction team and whether the construction is standard or not will affect the construction quality and use the effect of refractory castables.

Fourth, some special parts of the cement kiln, such as the front kiln product, the kiln head cover, the top of the cooler, and the sidewall, have the problem of difficult baking. For these parts, some cement companies do not use wood for baking at all, and some companies just bake for a short time. In the kiln drying stage with burners, due to the control of the cement kiln process parameters, the hot air flow is transmitted and radiated to the kiln tail system at a certain speed, while only part of the radiant heat energy is radiated to the kiln headcover and the cooler, which is not enough The free water in the castable is fully discharged. When the production starts, the hot airflow in the system flows back to the kiln head in a short time. At the same time, high-temperature clinker begins to accumulate on the kiln headcover, causing the temperature of the kiln headcover and cooler to rise sharply. At this time, the pouring material bursts and falls off most easily.

The above-mentioned many factors have caused the problem of castable bursting during the maintenance period of various cement manufacturers to be more prominent. As a result, every year in our country, the kiln headcover and the chiller castable burst and collapse due to the failure of the explosion-proof measures for the castable and the unreasonable baking system.

Lightweight thermal insulation castable, mainly used for the lining of thermal equipment such as the thermal insulation layer of high-temperature industrial kilns.

Insulating Castables Can Be Applied To Kilns To Save Energy

Construction of light-weight thermal insulation castable

Because the lightweight insulating castable( is made of certain refractory materials, such as alumina and other powdered and granular refractory materials added with some binders. It has high liquidity. In terms of construction, it is mainly formed by pouring.

Precautions for mixing lightweight castables

The variety of lightweight castables is different, and the mixing is also different. The amount of the hydration liquid binder must be accurate, and the various raw materials must be weighed and poured into the mixer without missing or adding more. When mixing cement, clay binding and low-cement lightweight castables, dry bulk materials such as bagged materials, additives and admixtures are first poured into the mixer for dry mixing for 1 minute. After uniformity, add water and wet mix for 3-5 minutes. The material can be discharged after the material is uniform in color.

Lightweight castables combined with water glass can be first poured into a mixer for dry mixing, and then water glass solution is added for wet mixing. After the particles are wrapped by water glass, add refractory powder and other materials. Wet mixing is about 5 minutes, and it can be used for discharge. If the dry ingredients are mixed together, pour them into a blender and mix for 1 minute, then add 2/3 of the water glass solution and mix for 2-3 minutes. Then, add the remaining binder and wet mix for 2-3 minutes before use.

Insulating Castables Has Low Bulk Density

The mixing of resin bonded castables is the same as the mixing of water glass bonded castables.

The mixing of phosphoric acid and phosphate combined with lightweight castables is to pour the dry materials into a mixer for dry mixing for 1.0 minute, add about 3/5 of the binder and wet-mix for 2-3 minutes before discharging. And it needs to be covered tightly with plastic film for trapping, and the trapping time is more than 16h. After weighing the trapped material, pour it into the mixer for secondary mixing, and add the remaining proportion of binder to wet mix for 2-4 minutes before use.

When mixing lightweight castables, if additional materials such as refractory fibers and organic fibers are required to be added to the materials, they should be sprinkled into the mixer for mixing continuously and uninterrupted during the wet mixing of the castables, mixing while sprinkling. After the lightweight castable is mixed out, if it is too dry and too thin, the castable can no longer be used.

Precautions for the construction of lightweight thermal insulation castables

For the construction of lightweight refractory castables, formwork must be supported first. The working surface of the template should be painted with oil or stickers. The height should be moderate each time the template is installed to facilitate material loading and vibration forming.

The surface of the lightweight castable should be covered with a plastic film to prevent water absorption from affecting the performance of the castable. If the furnace wall is high, the light castable construction should be carried out in layers to prevent the overturning of the insulation layer when the castable shakes.

If it is a light-weight refractory castable furnace roof construction, it must be in accordance with the design size requirements. First, the entire template is firmly supported and then oiled. The distance between the bottom end surface and the template surface is 0-10mm. When the amount of lightweight castable is small, it can also be mixed manually.
