They can be mainly used at oozing proof layer at though bottom,taking taking the place of refractory bricks and AL2O3 layer.
Products have high strength and low heat conduction rate,They can provent al liquid electricity liquid from coozing and eroding .so the using life of electrolysis troulysis thouht is lengthened.at the same time, they can provent electrolyte enters the refractory heat insulation laver. They can be easily used and the tem[erature rises puickly even you donot roast vit. They can be mainly used at oozing proof layer at though bottom,taking taking the place of refractory bricks and AL2O3 layer.
