The refractory bricks of the first furnace are baked, and the previous corundum refractory bricks must be almost completely defeated in terms of physical characteristics!

Not only the hardness and impact resistance, but also the bending and pressure resistance are much higher. The maximum temperature of corundum refractory bricks can reach 2200°, and such high temperature resistance can definitely meet most processing requirements.

Zhao Li looked at the new refractory bricks he had newly made, which were the refractory bricks he had added to the slag.

After this kind of refractory brick is burned, the whole body is white and obviously not an ordinary thing.

Interestingly, after the physical properties of this refractory brick were revealed, there was no excitement on the faces of these people.
