Fused cast AZS products, mainly in industrial alumina, zirconia, ZrO2 as raw material, through the refractory material of electric arc furnace melting, crystallization, casting, insulation, processing, production of the product. The product is the key materials of glass and glass products kiln, in accordance with the casting method, can be divided into ordinary (PT), tilt (QX), (ZWS) quasi shrinkage hole, shrinkage hole (WS), according to the chemical composition of products, can be divided into:Fused Cast AZS33# Fused Cast AZS36# Fused Cast AZS41#.
Fused Cast AZS TY-AZS33#
Shapes and sizes:
there are great variety of formats and shapes which are available for different forming and special machine processes.
Application:
Dense microstructure of Fused Cast AZS 33# bricks to glass corrosion resistant performance is good, not easy to produce slag and other defects in glass kiln.
It is the most widely used in the products of glass furnace, the upper part of the structure is mainly applicable to the molten pool, pool wall brick and tile work pool, material etc.
Fused Cast AZS TY-AZS36#
Shapes and sizes:
This product is only available for straight brick.
Application:
Fused cast AZS36# brick due to the increase in chain like zirconia more crystals, and glass phase content is relatively low, so the 36# fused zirconia corundum brick corrosion resistance has been further enhanced,So suitable for glass liquid velocity faster or high temperature region.
Fused Cast AZS TY-AZS41#
Shapes and sizes: this product is available in a large size straight or approximate bricks and special formats and shapes which are available for special machining processes.
Application:
Fused Cast AZS41# brick is in addition to silica, alumina eutectic in vitro,
It also contains more uniform distribution of zirconia crystals, in zirconia corundum brick system, its corrosion resistance is the best.
Therefore, selected key parts of the glass furnace, so that these parts of the life and the other part of the lower scale.
