Introduction of glass kiln and selection of refractory materials:

For large float lines, the structure of glass furnaces is usually composed of L-shaped hanging walls (usually using silica bricks), melting parts (the area in direct contact with the glass liquid should use electric fused bricks, and the area near the top should use s··· ...

How to solve the problem of insufficient bulk density of non-shrinkage fused bricks?

Fused α-β corundum bricks are made of high-purity sintered alumina (above) and a small amount of additives. After mixing, they are put into a three-phase electric arc furnace, smelted at a high temperature of more than 2300℃, and then cast into a special mold. Afte··· ...

Melting process of fused zirconium corundum bricks

Open arc melting (electrode is higher than the melt level) and closed arc melting (electrode is inside the batch) are different. Resistance system melting is that the electrode falls into the melt and the current heats the melt along the melt. In some cases, the fused··· ...
