High alumina castable Refractory

High alumina Refractory castable

Description of Fireramo high alumina castables

High-alumina refractory castable is a kind of monolithic refractory material composed of bauxite clinker, binding agent, and additives. High-alumina castables can be used for various heat treatment furnace linings and burners, and play an important role in industrial furnaces to protect the furnace body, provide a suitable reaction environment and extend the life of the equipment.

Characteristics of Fireramo high alumina castables

Fireramo’s high alumina castables are based on the ratios of traditional high alumina castables. We have adjusted the particle gradation, added different admixtures and reduced the amount of cement. The properties of the high alumina castables have been improved, with higher mid-temperature strength and load softening temperature, lower thermal conductivity and good thermal stability.

High temperature resistance

High alumina castable can withstand thermal stress and thermal shock under high temperature environment, and work stably for a long time under high temperature, keeping stable physical and chemical properties.

Good corrosion resistance

High-alumina castables have good corrosion resistance to a variety of acidic and alkaline media. It is able to resist acid and alkali erosion and is suitable for working environments dealing with corrosive gases, liquids or solids.

Excellent abrasion resistance

High alumina castable has high abrasion resistance and can resist the abrasion and scouring of granular materials in the furnace. It has excellent service life in abrasive media in industries such as metallurgy and mining.

Good flowability and castability

High-alumina castables have good fluidity and can be used to fill furnace chambers or other parts with complex shapes by pouring and injection. It can form an integrated refractory layer, ensuring the continuity and tightness of the overall structure.

Structural stability

High-alumina castables can form a solid structure at high temperatures, which can withstand thermal cycles and mechanical stresses inside the furnace chamber, and has good resistance to thermal shock and compression.

Applications of Fireramo high alumina castables

Metallurgical industry

High alumina castables are commonly used as linings and protective layers for metallurgical equipment such as metallurgical furnaces, converters, electric arc furnaces and blast furnaces. It can withstand high temperature and corrosion of chemical reaction substances, protect the furnace body and provide a suitable reaction environment.

Chemical industry

In chemical process, high alumina castables are widely used in the lining and refractory layer of various high temperature reactors, catalytic cracking units, coking ovens and other equipment. It can resist acid and alkali erosion and high-temperature corrosion, and keep the stable operation of the equipment.

Building material industry

High-alumina castables are often used as linings for refractory kilns, glass kilns, cement kilns and other building materials production equipment. It can withstand sintering and chemical reaction at high temperature to ensure normal production process and stable product quality.

Power industry

High-alumina castables are used in high-temperature equipment such as boilers, coal-fired furnaces and incinerators in power plants. It can withstand the erosion of high temperature flue gas and combustion materials, providing refractory layer and lining protection.

Iron and Steel Industry

High-alumina castables are widely used in various hearths and vessels in the ironmaking and steel smelting process, such as ladles, furnace bottoms, iron mouths and so on. It can withstand the impact and erosion of high-temperature molten metal and slag liquid, and extend the service life of the equipment.
