Some Common Sense of High Aluminum Castable

High aluminum casting material manufacturers believe that high aluminum lightweight casting materials are suitable for insulation and heat insulation parts, heavy casting materials are suitable for flame contact parts, and kiln lining uses a combination of light and heavy products to achieve better results. High aluminum lightweight castable, also known as high aluminum insulation castable, is a lightweight castable made from lightweight refractory aggregates, powders, binders, and additives.

High aluminum casting material manufacturers believe that the product characteristics of high aluminum lightweight casting materials are:

(1) High usage temperature and good insulation performance.

(2) Low bulk density, low thermal conductivity, reducing heat loss.

(3) Resistant to chemical corrosion and acid and alkali gases. The cast integral lining has a solid overall structure, good airtightness, and a certain degree of corrosion resistance.

High alumina castable manufacturers believe that lightweight refractory castables are widely used in industrial sectors such as metallurgy, machinery, petrochemicals, power, building materials, and other industries for lining kilns, thermal equipment, flues, and chimneys. Lightweight refractory castables are widely used as insulation materials. Medium to low temperature lightweight castable is mainly used as insulation lining and cannot come into contact with flames. High temperature lightweight castable is directly used for working linings that do not come into contact with molten or solid media in the furnace. The working lining of various heating furnaces and heat treatment furnaces can greatly save energy consumption.

High alumina castable manufacturers believe that heavy castable is a cement-based composite single component dry powder mortar made from industrial products such as high-strength cement, mineral admixtures, high-strength aggregates, crack resistance and wear resistance agents. High strength and wear-resistant castable can be used by adding water and stirring on site, which is convenient for construction. By manual plastering, a wear-resistant layer with a certain thickness is formed on the surface of the silo or ore tank, and the technical requirements can be met through normal maintenance. It has high wear resistance, high bonding strength with the foundation concrete, strong impact resistance, high compressive strength, and good durability.

Manufacturers of high alumina castables believe that adding steel fibers to heavy castables can significantly improve their resistance to peeling and impact. For areas with severe impact wear and high bending strength, steel fibers can be added to the castable. It is worth noting that the distribution of steel fibers has a significant impact on the quality of refractory castables, and the random and disordered distribution of steel fibers in refractory castables is good. So pay attention not to take too long to vibrate. Steel fiber reinforced refractory castable must be poured in one go, and if poured in two stages, there is a high possibility of peeling between the two layers.

High aluminum casting material manufacturers believe that the porosity of the product in the casting material is not less than 45%, making it a lightweight insulation material mainly used for insulation layers; Another type of densification material is heavy castable, mainly used in important refractory and wear-resistant parts of high-temperature furnaces and boilers.

The above are some knowledge points about high aluminum casting materials. I hope everyone can study and understand the relevant knowledge carefully, and choose products and equipment that are suitable for their needs.
