Spout and Repair Material manufacturers take you to understand the castable production process and equipment

Spout and Repair Material manufacturers tell you that castables are basic materials serving high-temperature technology, especially closely related to the metallurgical industry, and their quality and variety play a key role in the development of high-temperature technology.

Spout and Repair Material manufacturers tell you that the production process of castables mainly includes raw material calcination, raw material processing, molding material preparation, molding, green body drying, firing, etc.
There are two main equipments for calcining raw materials of castables: shaft kiln and rotary kiln. Shaft kiln is composed of kiln body, feeding and discharging device and ventilation equipment. The shaft kiln works according to the principle of countercurrent heat transfer. Spout and Repair Material manufacturers tell you that the raw material of the castable and the hot gas flow relatively, the raw material falls from the top, and the gas rises from the bottom.
Castable raw materials need to go through three zones in the shaft kiln: preheating zone, calcining zone and cooling zone. Spout and Repair Material manufacturers tell you that in the preheating zone, the raw materials are preheated with the help of the heat of the flue gas; in the calcining zone, the castable raw materials are calcined with the help of the heat released by the combustion of the fuel; in the cooling zone, the calcined raw materials are The blown cooling air conducts heat exchange, the raw material is cooled, and the air is heated and then enters the calcining zone for combustion support.
Spout and Repair Material manufacturers tell you that the castable production process is an important indicator to measure the technical level and production level of a refractory manufacturer. The level of the production process is also related to the quality of the castable products. At the same time, the main equipment used in the production of castables It is also closely related to the quality of castable products.
