Description

What are Fused Cast AZS 36# Refractory Blocks?

Fused cast AZS 36# blocks made from a combination of alumina (Al2O3), zirconia (ZrO2), and silica (SiO2) are the better quality grade of fused cast refractory blocks used in the glass furnace. Fused Cast AZS 36# blocks denotes the percentage of ZrO2≥35.5%. Different Companies may have different indication codes for this quality grade. For example, SEPRO uses ER 1685 for AZS 36#, and REFEL uses 1334 for AZS 36#. With the medium zirconium oxide content, Fused Cast AZS 36# Refractory block is designed to provide better resistance to glass corrosion than AZS 33#. Its chemical and physical properties make it be used in more aggressive area of the glass furnace

Classification and Properties

Fused cast AZS 36# Refractory blocks are normally classified into two quality grades:

AZS 36#ZWS (End Cut Casting) and AZS 36#WS (Void Free)
Fused cast AZS 36# blocks have better resistance to high temperatures and corrosive environments in the glass furnace operation.

Applications

Because of fused cast AZS 36# blocks’ better performance to withstand the more corrosive environments in glass furnace operation, they are normally used in some crucial positions of glass furnace, like melting tank sidewall,Barrier Wall, Throat Covers and etc.
