PRODUCT DESCRIPTION

Introduction:

Cast big mullite brick is a kind of sintered mullite brick, which is mainly suitable for the production of special-shaped products. The blocks are formed by slip casting. The raw materials are mixed into a paste and injected into the plaster mold, which is manually made, drying, and firing.

Features:

The product has excellent creep resistance, good high-temperature performance, high refractoriness, excellent refractoriness under load, good thermal shock resistance, low thermal expansion coefficient, and acid slag erosion resistance.

l  Good compactness

l  High Purity

l  Corundum Phrase 70%, Baddeleylite content 19%

l  Excellent thermal shock resistance

l  Good spalling resistance

Applications:

Opal glass furnace, High borosilicate glass furnace, serious erosion parts of glass furnace: crown, port arch, hook brick, peephole bricks, burner bricks, feeder bricks, dog-house crown

Cast big zircon mullite refractory bricks are made from fused zirconia mullite and sintered alumina as the main raw material and hydrated alumina as the binder. with good compactness and high purity, its corundum phase is greater than 70%, the content of zircon is greater than 19%, and the content of mullite is greater than 7%. With properties of good resistance to thermal shock and spalling, and strong corrosion resistance, it can be used in serious erosion parts of glass kiln, like main crown, port arch, hook brick, peephole brick, burner brick, feeder brick and dog-house brick etc, it is also the first choice for opal glass furnace and high borosilicate glass furnace.
