Definition:
Refractory brick is referred to as fire brick. Refractory made of refractory clay or other refractory materials. Pale yellow or brown. It is mainly used for building smelting furnaces and can withstand high temperatures of 1,580℃-1,770℃. Also called firebrick. Its refractories is usually above 1750 °C.The main mineral components are corundum and mullite phases.It is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion.
According to the preparation process, it can be divided into fired bricks, non-fired bricks, fused bricks (fused cast bricks), refractory and heat insulation bricks; according to the shape and size, it can be divided into standard bricks, ordinary bricks, special-shaped bricks, etc.
Fireproof Resistant Fire Clay Brick is made from clinker clay by mixing, forming, drying, sintering and matching characterized by good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.
Advantage:
1. High refractoriness,
2. High-temperature endurable.
3. Good corrosion resistance.
4. Good spalling resistance and wear resistance.
5. Good thermal shock resistance.
6. High mechanical strength.
7 .High-temperature creep rate is low.
8. Good volume stability at high temperature.
Application:
Fireproof Resistant Fire Clay Brick can be used to furance contruction,blast furance/hot blast stove,steel foundries,furnace in the nonferrous metal industry,coke oven and gas furnace,galss industry,cement industry,safty lining of ladle and backup lining of boiler
1) Iron&steel making industry.
2) Petrochemical, metallurgical, ceramics, glass industry, the furnace lining insulation.
3) Heat treatment furnace backlash insulation.
4) Non-ferrous metal industry.
5) High temperature reaction, heating equipment back insulation insulation
