The baking of refractory castables before use is an important link in the production process. Whether the roasting system of the castable is reasonable or not determines the quality of the green body roasting, which directly affects its performance, the manufacturer's production technology and economic benefits. If the refractory castable is used carelessly, it will be damaged, so how to avoid it?
First of all, refractory castable is a widely used refractory insulation material, especially suitable for some places that need high-temperature calcination, but sometimes it may be damaged during use.
The refractory castables of different manufacturers have different formulas and compositions. The main components in refractory castables refer to the most common chemical components that have a decisive influence on the high-temperature performance of the castable. Refractory castables have excellent properties. The role of high temperature resistance, and the characteristics of many refractory castables, are based on the main component and additional component additives. At the same time, if some manufacturers have too many castable impurities, it will cause damage and problems in future use. Therefore, the composition of the refractory castable plays a decisive role in the high temperature performance of the castable.
In addition, physical factors are also important factors leading to the damage of refractory castables. Too high temperature will cause local cracking of refractory castable. Improper use or mixing of liquid metal into the castable can also cause pouring. Material damage.
The second factor that causes damage to the refractory castable is the chemical factor, because slag is generated in the furnace, and the furnace gas and the refractory castable chemically react. In addition, the corrosive substances produced by electrochemistry will also cause local damage to the refractory castable. Therefore, refractory castables should not be put together with highly corrosive substances during the construction process.
Then the refractory castable caused by mechanical construction will be impacted and damaged, so you need to pay attention to it during use.
