Mullite

Product Description

Mullite is a kind of high quality refractory materials, it has a uniform expansion, hot pillow excellent stability, high load softening point, high temperature creep value is small, high hardness, good resistance to chemical corrosion, there are mainly high purity fused mullite, fused mullite sintered mullite, all natural bauxite concentrate and light mullite.

1. The sintered mullite

Using natural high quality bauxite by multi-stage homogenization, through more than ***0 ℃ high temperature sintering. Has a large volume density, stable quality, good thermal shock resistance, high temperature creep value performance characteristics such as small and good resistance to chemical corrosion. Is the production of various shape and body not stereotypes refractories, high-grade sanitary wares, such as precision casting model ideal raw material of refractory material products.

2. Lightweight mullite aggregate

This product is the use of natural bauxite as raw material, adopting reasonable technology was suitable for the high temperature of ********0 ℃ using lightweight aggregate.

The characteristics,

1, the use of high temperature, can be directly contact working lining using flame, high temperature energy saving.

2, low thermal conductivity, heat preservation performance is good, special lightweight mullite aggregate ingredients, volume stability, high strength, good airtight structure.

3, ****0% reduction in weight structure, eliminate the roof hanging brick is broken.

4, can fast oven, high exhaust air voids is smooth, shorten oven period, the economic benefit is remarkable.

Second, the scope of use

Various flame furnace lining work, direct contact with the flame (not contact melt), other high temperature heat preservation and heat insulation equipment, such as:

1, the preparation of various lightweight refractory castable, spray coating, etc.;

2, heating furnace, soaking furnace, heat treatment furnace, annealing furnace, ceramic, refractory products sintering furnace, the furnace wall.

3, steam boiler, oil industrial tube furnace, ethane cracking furnace lining.

4, all kinds of industrial furnace door, observation hole lining

3. Calcination mullite

Natural calcination mullite series product, USES the high quality coal measures kaolin as raw material, by high temperature calcination. Products with a dense texture, high hardness, small expansion coefficient, wear resistance, good thermal and chemical stability. Mainly used in metallurgy, building materials, chemical industry, refractory material, military industry, etc.

4. Fused mullite

Selects high quality pure natural mullite ishihara mine, through advanced industrial furnace high temperature burning fuse. Expansion uniformity, excellent thermal shock resistance, high load softening point, high temperature creep value is small, high hardness, good resistance to chemical corrosion, etc. Mullite is metallurgy, ceramics, building materials, chemical industry, electric power and casting of ideal material.

【 mullite using range 】 :

High temperature mullite stone producing by mullite insulation bricks with high temperature resistance, high intensity and small coefficient of thermal conductivity, remarkable energy saving effect is suitable for oil cracking partition kiln, metallurgical hot stove, ceramic kiln, tunnel kiln, electric porcelain crucible kiln drawer kiln, glass and various electric furnace lining, can direct contact with the flame.
