<a href="http://fusedcastazs.com/fused-cast-azs-block/">fused cast azs block</a> as a refractory block plays an important role in glass furnace. The main chemical composition of fused cast AZS block is Al2O3, ZrO2 and SiO2, and Al2O3 has the special property of a relatively high thermal conductivity, ZrO2 has the property of superior mechanical, thermal, electrical, chemical and optical properties. When they are bonded together with special method, their good performance is revealed to fused cast AZS block.

Fused cast AZS block is made of pure alumina powder and zircon sand and produced through casting technology method which is by melting the raw material in the electric furnace, then casting into various molds and cooling themselves down to become solid. According to the different content of ZrO2 from 33%-41%, fused cast AZS block can be divided into three types which is fused cast AZS block33# 36# 41#, in addition, the casting technology has different grade, and different type of fused cast AZS block can adopt different grade casting technology, so different types of fused cast AZS block using different casting technology has different characteristics, applications are also different.

The most prominent feature of fused cast AZS block is dense structure which results in the low potential for stoning, blistering and exudation of the matrix glass. In addition, fused cast AZS block has the property of high corrosion resistance and low pollution to glass liquid, and long service life.
