1. Seretse se nang le mouoane se entsoeng ka letsopa
Litšebeliso tsa Bohlokoa:E loketse ho beha litene tse hanelang tse thehiloeng letsopa libakeng tse nang le mocheso o kaholimo ho 1350℃, joalo ka likarolo tse mocheso o tlase tsa li-oven tsa indasteri, li-flue, li-chimney, likarolo tse tlase tsa li-regenerator tsa litofo tse chesang, le li-lining tsa boiler—kaofela li le libakeng tse nang le mafome a tlase, tse mahareng ho isa ho tse tlase.
Likaroloana:Litšenyehelo tse tlase, ho sebetsa hantle, ho hanyetsa mocheso le pholiso ka potlako ka mokhoa o itekanetseng; ha e lokele libaka tse qhibilihisitsoeng tse nang le mocheso o phahameng/libaka tse senyang haholo.
2. Seretse se nang le alumina e ngata se hananang le ho tjhesa
Likopo tsa mantlha:NM-50/NM-60: E loketse litene tse nang le alumina e ngata (Al₂O₃ 55%~65%), tse sebelisoang karolong ea mocheso o mahareng oa li-kiln (1350~1500℃), joalo ka li-kiln tsa ceramic, li-oven tsa metallurgical tse futhumatsang, le libaka tsa phetoho ea samente ea rotary kiln; NM-70/NM-75: E loketse litene tse nang le alumina e ngata (Al₂O₃ ≥70%) kapa litene tsa corundum, tse sebelisoang karolong ea mocheso o phahameng (1500~1700℃), joalo ka li-lining tsa blast oven, li-tapholes tsa steelmaking converter, li-regenerator tsa khalase oven, le li-lining tsa calcium carbide oven.
