How to improve the wear resistance of refractory brick

How to improve the wear resistance of refractory brick Refractory bricks are generally made at room temperature and used at high temperature. Therefore, refractory bricks with high wear resistance usually refer to high temperature wear resistance. For the study of wear resistance, we can start with the strength of refractory brick. The improvement of strength…

What is the pressure weight that high alumina bricks can wit

What is the pressure weight that high alumina bricks can withstand? The compressive strength of high alumina bricks is a physical index, but in actual production and use, the compressive strength is an easily achieved index. The most difficult index to achieve is the Refractoriness Under Load(RUL). So how much pressure can the high-alumina brick…
