Application Summary AI generated
GB/T 22590-2021 specifies the classification, technical requirements, test methods, inspection rules, and packaging of refractory castables used in rolling mill reheating furnaces. It is applied in the steel industry for lining and repairing the high-temperature zones of reheating furnaces, where the castables must withstand thermal shock, slag erosion, and mechanical wear during continuous steel billet heating. This standard ensures material performance consistency for furnace construction and maintenance in steel rolling production lines.
