Precautions for use:

Because steel ladle is a container, it plays an important role in steelmaking. In order to improve the ladle life and reduce the consumption of refractory materials. Steel ladle castable for sale from the economic, labor saving, environmental protection and other aspects, pouring construction has become an effective ladle construction method, pouring construction advantages also promote the development of just reported.

With the steel mill production process more and more stringent requirements, the development of continuous casting and refining outside the furnace, the time of molten steel in the steel ladle is prolonged. Thus, the damage of molten steel to the lining is accelerated and the steel ladle life is low. Therefore, high grade, high strength refractory castable is required. And our production of steel ladle refractory castable is fully in line with the needs of steelmaking production process, long service life, high strength, welcome to consult.

Steel fiber castable advantages

1. Good air tightness, good insulation effect, long service life. Under high temperature use, furnace lining does not produce directional shrinkage, no cracks, furnace lining integrity is good.

2. The construction technology is simple, the speed is fast, the material consumption is small.

3. It has good mechanical properties, a certain strength, a certain bearing capacity, strong resistance to airflow erosion. The burning nozzle brick made of steel fiber castable can be used for a long time under the condition of temperature ≤1200°C.

4. It has good adaptability to the atmosphere in the furnace and can be used in various fuel furnaces. In reducing atmosphere for a long time use furnace lining stability, enhance toughness, improve stress and strain resistance, improve mechanical impact.

5. Improve thermal shock resistance, crack resistance and spalling resistance.

6. Restrain linear shrinkage after curing, drying and heat treatment.

Steel fiber castable is made of super grade bauxite clinker as aggregate, high quality bauxite clinker and corundum fine powder as matrix, ultramicron powder and a variety of composite materials as binder and additive, and stainless steel heat-resistant fiber. This series of refractory castable has the wear resistance at high temperature. In addition, a certain amount of heat-resistant stainless steel fiber is added in the ingredients to prevent the swelling and difference between the aggregate and the matrix in the material in the high temperature state, and the stress caused by the change of temperature gradient when the furnace is started and stopped, which leads to the destroy of the furnace wall. In CFB boiler, often used for furnace outlet and side wall, top, straight section of cyclone separator, cyclone separator top, return feeder and other parts.

Clay Refractory Castable Introduction

Physical and chemical indexes of clay castable include content of chemical components, bulk density, refractoriness, compressive strength, flexural strength and rate of change after firing.

Refractory clay castable is made of refractory clay clinker as aggregate. Added with other powder, soft clay and other binder and additive, prepared according to formula proportion. Stirred in order, mixed and stirred according to technical requirements, the use temperature is generally 1300-1450℃.

We are clay refractory castable manufacturer,the refractory castable produced by our factory has a wide range of applications, which can be applied to a variety of high-temperature industrial kilns. Such as soaking furnace, heating furnace, heat treatment furnace, boiler, rotary kiln preheating zone, blast furnace, electric furnace, converter and other industrial kilns lining.

This series of refractory castable can also be customized according to customer requirements. Different physical and chemical indicators of refractory castable, applied in the kiln range is different, the use effect is not the same.

Moreover, the aluminum content of refractory castable can also be produced according to customers’ requirements. The content of Al2O3 ranges from 30% to 48%, and the volume density also needs to be divided. The level of the castable index can be controlled by its formula and the refractory materials used. Therefore, the physical and chemical indexes of the castable for different purposes are also different.

The mullite castable choose high quality mullite raw materials, high temperature stable performance and applicable to a variety of flame furnace, steam boiler, heating furnace, rotary kiln and other industrial kiln lining, can according to the needs of industrial kiln, processed into various special castable, such as corundum mullite castable, low cement mullite castable, steel fiber reinforced mullite castable, mullite castable wear-resisting and so on. Strong adaptability, excellent performance, welcome to buy.

Mullite as the main refractory aggregate of mullite refractory castable, has an important influence on the performance index of the mullite. Therefore, in the production of mullite castable, it is necessary to strictly control the particle size of raw materials and the proportion of formula, and strengthen the production process of mullite castable. Avoid failure due to errors.

The bulk density of mullite castable has an important relationship with the refractory materials and production process selected by the castable. The bulk density of mullite castable can be controlled according to the selected refractory material, the bulk density of mullite castable is one of the factors that affect the application of industrial kilns and the price of mullite castable.
