ZrO2≥35.5%
Al2O3≥46.5%-49.5%
Bulk density: ≥3.8-3.9
Application:
Fused cast AZS36# Block are normally used in some crucial positions of glass furnace, like melting tank sidewall,Barrier Wall, Throat Covers and etc.
Introduction of fused cast AZS 36# 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 of fused cast AZS36# blocks:
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.
