Introduction: There are many types of castables, but the most popular ones are corundum castables, such as white corundum castables and brown corundum castables. White corundum sand has a common property, high temperature resistance and thermal stability
There are many types of castables, but the most popular ones are corundum castables, such as white corundum castables and brown corundum castables. White corundum sand has a common performance, high temperature resistance, good thermal stability, and resistance to acid and alkali corrosion. Therefore, white corundum is also widely used in refractory materials, one of which is castable.
Speaking of castables, many people may not know it well. Its use is mainly for the lining materials of various kiln. Next, I will briefly introduce some precautions in the use of white corundum castables:
1. The temperature of the water to be stirred should be appropriate. It should not be higher than 25 ℃ in summer and the water temperature in winter should be kept between 30 ℃ ~ 50 ℃.
2, can not be exposed during use, shading treatment should be done;
3. The place of use can be in a covered workshop and so on.
The above three conditions are to prevent the temperature from affecting the performance of the white corundum castable, mainly because the temperature is too high or too low, which has a great impact on the acid and alkali resistance of the white corundum castable. !
