Brand:Wilead
Model:Fused mullite
MOQ:20 Metric Ton
Fused mullite, using high purity quartzite and industrial alumina powder as
main starting materials, smelting in tilting electric arc furnace, is a new kind
of high purity synthesized refractory raw materials. The fused mullite, gray,
low residual carbon, is characterized by good acicular crystal structure,
high modulus of rupture, symmetrical expansion, and excellent thermal
shock resistance, high refractoriness under load, small high temperature
creep value, high hardness and good chemical corrosion resistance.
Fused mullite, mainly used for low creep brick for hot blast stove, sillimanite
brick, torpedo ladle brick, bricks for high temperature industrial furnaces, lining brick of glass tank, bricks for large-scale iron-making hot blast stove, sagger, deck and other thermal shock resistance
ceramics kiln furniture, is an ideal refractories, Fused mullite is also a high
quality material improving the toughness of mullite refined ceramic and
monolithic refractories.
