Acid-resistant castable material
Acid-resistant castables have good resistance to all inorganic acids and organic acids except for hydrofluoric acid and hot phosphoric acid. The production process and construction are simple, with high material utilization. They have high strength at room temperature and can also be made into prefabricated parts for installation on-site in kiln rotating work, such as lining castings in chimneys.

Corundum-based castables include corundum castables, corundum plastic materials, corundum ramming materials, and corundum wear-resistant materials. Corundum-based products are made from refractory materials with an Al₂O₃ content greater than 90%, primarily consisting of corundum as the main crystalline phase, and are compounded with appropriate amounts of dispersants, setting agents, stainless steel fibers, according to strict formulations.

Seepage-proof pouring material
During use, it can react with alkali metal ions in the electrolyte to form a barrier membrane, thereby achieving the purpose of preventing leakage.

Non-stick aluminum casting material
Improved the corrosion resistance, abrasion resistance, non-stick aluminum, and slag function of refractory materials against aluminum liquid containing salt, flux, and other chemical components, preventing aluminum and alloys, as well as slag, from penetrating the refractory materials. Widely applicable to melting furnaces, holding furnaces, troughs, and aluminum-lined interiors.
