Fused Cast AZS Block

Fused cast AZS block is an important refractory material to ensure the normal operation of glass melting furnaces. At present, glass melting furnaces increase the melting rate, extend the life of the furnace, and reduce fuel consumption mainly due to the use of this refractory material.

Product Introduction

Description

Fused cast AZS block manufacturing process mixes selected zircon sand and industrial alumina powder at a ratio of 1:1, plus a small amount of Na2O (added in the form of sodium carbonate), B2O3 (added in the form of boric acid or borax) flux, and mix well After being melted at 1800~1900℃, it can be cast to form a fused-cast brick containing 33% ZrO2. On this basis, using partially desiliconized zircon sand as raw material, fused-cast bricks containing 36% to 41% ZrO2 can be produced.

Features

Fused cast AZS block has the characters of good corrosion resistance , low pollution , good chemical stability and reduce fuel consumption.

AZS brick

Application

Fused cast AZS block is mainly used in industrial furnaces such as glass melting furnaces. The use parts in the glass melting furnace are the masonry of the upper pool wall, small furnace slabs, small furnace stacks, tongue hangings and breast walls.
