Product Description

The Al2O3 content of the lightweight fireclay bricks is generally more than 40%, and the Fe2O3 content is less than 2.0-2.5%. The clinker in the ingredients is 65-85%, and the combined clay is 35-15%. The lightweight fireclay insulation bricks is usually produced by the combustible method, and can also be formed by the chemical method or the foam method to form a porous structure.

The crushed combined clay and the finely ground clinker are mixed and ground, and then mixed with the granular clinker to prepare a semi-dry mud, which is molded under high pressure and fired in an oxidizing atmosphere at about 1400°C. The lightweight fireclay insulation bricks are weakly acidic at high temperatures. The lightweight fireclay insulation bricks are refractory materials with high porosity, low bulk density and low thermal conductivity. Thermal insulation refractories are also called lightweight refractories, which include insulation refractory products, refractory fibers and refractory fiber products.

The bulk density of commonly used lightweight fireclay bricks is 0.5-1.3g/cm3, the compressive strength is 2.0-9.8Mpa, and the thermal conductivity is 0.221-0.442W/(m.K) (1350℃). The light weight fire clay insulation refractory bricks are characterized by high porosity, generally 40%-85%; low bulk density below 1.5g/cm3; low thermal conductivity, generally below 1.0W (m.K).

The lightweight fireclay bricks is used as an industrial furnace Thermal insulation materials can reduce heat loss in the furnace, save energy, and reduce the quality of thermal equipment. Thermal insulation refractories have poor mechanical strength, abrasion resistance and slag corrosion resistance, and are not suitable for the load-bearing structure of the kiln and direct contact with slag, charge, molten metal and other parts.

The lightweight fireclay bricks Feature:

1. Containing a large number of closed pores

2. Have a lightweight high temperature

3. Good insulation properties

4. Refiring small contraction

5. Excellent thermal shock resistance

6. Strong resistance to the corrosive gas and slag.

The lightweight fireclay bricks Advantages:

1. Low thermal conductivity.

2. High strength and resistance to corrosion.

3. Low heat capacity.

4. Low shrinkage after heavy firing.

5. High insulation.

6. High refractoriness.

7. Low density.

8. Good thermal shock resistance under high temperature.

9. Thermal insulation energy-saving effect is good.
