Fusion Al2O3 Heat Insulation Brick 1900C Cast Iron Fire Brick

Fusion cast brick heat insulation Refractory Materials Iron and steel smelting

Product introduction

Refractory fired from refractory clay or other refractory materials. Light yellow or brown. It is mainly used in building smelting furnace and can withstand high temperature of 1580 ℃ - 1770 ℃. Also called refractory brick. Refractory of certain shape and size. According to the preparation process, it can be divided into sintered brick, non sintered brick, fused cast brick (fused cast brick) and refractory and heat insulation brick; It can be divided into standard brick, ordinary brick, special-shaped brick, etc. according to shape and size. It can be used as the structural material of high-temperature building materials, building kilns and various thermal equipment. It can withstand various physical and chemical changes and mechanical effects at high temperature. Such as refractory clay brick, high alumina brick, silica brick, magnesia brick, etc.

Use

The manufacturing process of electromelted brick is to mix carefully selected zircon sand and industrial aluminum oxide powder according to 1:1, add a small amount of NaZO(in the form of sodium carbonate), B2O(in the form of boric acid or borax) flux, mix evenly, melt at 1900~2000℃ after casting, can be prepared containing 233% ZrO cast brick. On this basis, casting brick containing 36%~41% ZrO2 can be prepared by using partial desilicized zircon sand as raw material.

Zircon brick

Fused brick is a white solid formed by melting pure aluminum oxide powder (Al2O3) and zircon sand containing 65% zirconia (ZrO2) and 34% silica (SiO2) in an electric furnace and then injecting it into the model for cooling. Its lithofacies structure is composed of the eutectoid and glass phase of corundum and zircon clinite. Physiologically speaking, it is a eutectoid of the corundum and plagioclase phases, with the glass phase filling between their crystals.
