What Is Wrong Quartz Firebrick? What Are Its Properties And Uses?
In use, zircalite refractory brick is high, by the chemical erosion of slag is not easy to dissolve, but the slag can penetrate through the pores to the interior of the brick, and at the same time react with the decomposed zircalite particles to form a metamorphic layer, so that the structure of the refractory brick collapses.
In order to improve the use effect of zircon refractory brick, it is necessary to reduce the penetration of its slag. In actual production, while reducing the porosity of refractory brick products, high aluminum rock or electromelting alumina can be added to zircon material to make aluminum-forming refractory brick. Improve the penetration resistance of products. When chromium oxide is added to zircon, the refractoriness is slightly reduced. Although the slag penetration resistance of zirconium aluminum brick has been improved, the slag erosion resistance is still poor. Chromium oxide can be added to refractory bricks to strengthen the erosion resistance of the matrix.
