High Alumina Low Cement Castable for Heating Furnace Top and Bottom Wall by Henan LLC

Henan LLC refractory castables manufacturer high alumina low cement castable for heating furnace top and bottom wall

High alumina low cement castable for ring heating furnace is a kind of refractory castable commonly used, which includes a very wide range.

Low cement castables refer to castables with a lower amount of cement. The cement dosage of refractory cement castables is generally 15% to 20%, and the cement dosage of low cement castables is about 5%, and some are even reduced to 1% to 2%. The purpose of reducing the amount of cement is to improve the refractory properties of the castable.

As long as the test results, aluminum (AL2O3) content ≥42% of the refractory castable, can become high alumina refractory castable.

Alumina refractory castable is made of bauxite clinker as aggregate and powder, and binder is added.

Characteristics of low cement castables:

Due to the use of ultrafine powder (micropowder) instead of calcium aluminate cement, low cement castables have the following characteristics:

(1) The low content of CaO in the castable can reduce the formation of eutectic phase in the material and improve the refractory temperature, high temperature strength and slag corrosion resistance.
(2) The water consumption of castables during construction is 4%-6% of ordinary castables, with low porosity and high bulk density.
(3) After pouring and forming, the cement hydrate generated during curing is small, and there is no damage to a large number of water-spray bonds during heating and baking, which reduces the strength at medium temperature. With the increase of heat treatment temperature, the strength gradually increases.
(4) The particle size composition of the castable can be adjusted appropriately to make self-flowing castable and pump pouring castable

Application of low cement castables:

Low cement castables are mainly used in metallurgy, electric power, non-ferrous metals, petrochemicals, building materials and other industries. Such as the bottom of glass kiln, the front end of the kiln door cover of the cement kiln and other high temperature resistant parts, the front and rear kiln mouths, coal injection pipes, etc.; various heat treatment furnaces such as heating furnaces and soaking furnaces; medium frequency induction furnace lining, petrochemical catalysis High temperature wear-resistant lining of cracking reactor, lining of other industrial furnaces.
