High refractoriness and high alumina content Refractory brick

Main raw materials of Al2O3,SiO2,CaO etc. Supplying standard and unregular shapes bricks. Make order to any sizes for customer

1.Alkalinity refractory brick technical specification,Refractory brick's major targets  are refractoriness, the refractoriness under load, reheats the line change, obviously porosity, compressive strength, bulk density, heat shock stable and so on.

2. Alkalinity refractory product taxonomic approach

  The fire-proof material varied assortment, the use is complex, the main taxonomic approach is as follows,

a. According to chemistry - mineral constituent classification, Loam brick, high aluminum ingot, silicon brick, magnesia brick, magnesium chromium brick, carbon block and so on;

b. According to refractoriness classification, The ordinary fire-proof material, refractoriness is 1580°C~1770°C; High-quality fire-proof material, Refractoriness 1770°C~2000°C; The top grade fire-proof material, refractoriness is bigger than 2000°C;

 c. according to formation craft classification, Casting formation; Plastic formation; The semi-dry process formation, pounds makes into and the casting product;

d. According to burn method classification, Burns the make bricks; Does not bake bricks and the electricity melt refractory brick;

e. According to size and brick classification, Sign; Pu and heterogeneous type;

f. According to purpose classification,Steel mill; Ceramic factory, power plant; the petroleum chemical industry uses the refractory brick.

3. Loam brick the loam brick is makes the aggregate by the chamotte, the chamotte makes the cement manufacture the aluminum content is 30%~ 48% refractory products. The loam brick is broader than other refractory brick application scope, mainly applies in the blast furnace, the hot-blast stove, the glass kiln and so on.

4. High alumina bricks

The high alumina brick’s aluminum content is higher than 48%.

First level, The aluminum content is bigger than 75%; Second,Aluminum content 60%~75%; Third, Aluminum content 48%~60%;

Because the high alumina bricks has the resistance high temperature and high load capacity ability, therefore widely applies in the blast furnace, hot-blast stove, electric stove and so on.
