▶ Description:
High dense zircon block consists of two kinds of bricks- HDZ-65 and HDZ-68. Characterized by high bulk density, low apparent porosity, mechanical strength, excellent stability of thermal shocking and resistance to corrosion of glass liquid under load, it is mainly used for soda-lime glass kiln, channel blocks as well as sidewall of glass fiber kilns and floating glass tanks.
▶ Applications:
Zirconia brick is versatile in the following industries:
◆ ladle lining for metallurgical industry.
◆ suitable for transition region between up roof silica brick and fusion zirconia-corundum brick or fusion zirconia-mullite brick.
◆ used in soda-lime glass kiln as neutral brick, skew brick.
◆ suitable in upper area of flame space or frequent thermal shock region as well as in lining of alkali-free or low-alkali glass, sodium-calcium glass, boron-silicate glass, ceramic glass, lead glass and other technical glass melting furnace.
◆ widely used in glass contact portion of alkali free or low-alkali glass melting furnace.
◆ suitable for paving and sub paving, channel blocks, sidewall of meter of glass fiber furnace and floating glass tanks.
◆ ideal for glass tank, such as paving part and secondary layer of paving bottom, back lining ,wall and bottom of fore hearth, flowing spout and spinning portion and melter, etc.
◆ suitable for transition region between silica brick and magnesia brick, areas of crown, burner, thermal couple, peep hole, and secondary layer of melter bottom and its back lining, etc.
