Castable intermediate frequency furnace knotting refractory is a high temperature amorphous amorphous refractory with dry fire retardant mixture. Also known as fireproof castable, it is a mixture of particles and powdery materials with high fluidity made of binders and refractories. Castables are based on forged non-shaped refractory materials, which are soft and suitable for the construction and maintenance of industrial production kiln bodies. This refractory material is generally used in the lining of heat treatment furnaces, some are perfect, and even used in melting furnaces, such as aluminate cement, high-aluminum cement and polyphosphate concrete. Medium frequency furnace ramming material

Castable is a granular powder made of refractory material with an adhesive. As amorphous refractories, castables have a high degree of fluidity and are produced by pouring or spreading. Different from other amorphous refractories, fireproof castables have initial setting and hard bottom time after construction. After forging, after a period of maintenance, the castable material needs to be removed, and then after the appropriate natural maintenance time, the material is poured dry.

1. The whole production process is simple, the production cycle is short, and the labor productivity is high.

2, castable has a strong elasticity, not limited by the architectural appearance used in industrial production. Can achieve the results you want.

3, with good consistency, sealing and temperature resistance, can reduce industrial furnace heat damage, save energy.

4, castable makes the foundation construction more convenient, saving human resources and time.

5, for the damaged industrial production charge, easy maintenance.

Castable is a kind of amorphous refractory material widely produced and used at present, which is mainly used to build the whole structure of various heating furnace linings. Some varieties can also be used in smelting furnaces. Such as aluminate cement castable can be widely used in a variety of heating furnaces and other slag free, no acid and alkali erosion of thermal equipment. In the parts of hot metal, molten steel and slag erosion and high operating temperature, such as steel tank = steel bucket and blast furnace body, iron ditch, etc., can be used by low calcium and pure high aluminum cement combined with high alumina content and good sintered granular and powder castable. For example, phosphate castables can be widely used in heating furnaces and uniform furnaces for heating metals, and can also be used in coke ovens and cement kilns where the material is directly in contact with the material. In some parts of metallurgical furnaces and other vessels that are in direct contact with molten slag and molten metal, the use of phosphate castables for repair also has good results. In some parts where the working temperature is not very high and the wear resistance is high, the use of phosphate castable is more appropriate, if the castable made of corundum refractory material is selected, the use of reducing gas content generally has a good effect.

When cement is used as a binder, in the process of high temperature use, because cement can decompose and dehydrate and produce other phase changes and sintering, the castable changes in volume and structure at the same time. Due to the formation of different components and structures in the cement stone, even the furnace lining becomes a layered structure. Between various layers, when a variety of different objects are formed, internal stresses or even cracks may occur due to changes in specific volumes. In the sintering zone, because the granular material has been pre-burned, cracks are easy to occur along with the considerable damage between the cement stone and the granular material, and the flake cracks parallel to the working surface may occur between the sintering zone and the two layers that are dehydrated but not sintered. When the temperature fluctuates, the stress caused by the different thermal expansion rate can cause the furnace lining to peel off along this crack. The main cause of cement failure is the loose structure caused by the decomposition of cement and the easy spalling due to the lamellar structure of cambium.
