Mphamvu Yapamwamba Yotsika Simenti ya Corundum fireclay Refractory Insulation Castable
Ntchito: Lining a aluminiyamu kusungunuka ng'anjo
Integral casting metallurgical ng'anjo ya ng'anjo ndi njira yopangira ng'anjo yachitsulo yomwe ma refractory castables amagwiritsidwa ntchito kuponya zida zokanira za ng'anjo yamoto nthawi imodzi.Makhalidwe a teknolojiyi ali mu umphumphu wake wamapangidwe abwino, opanda zingwe za njerwa, ndi mphamvu zambiri, kotero thupi la ng'anjo limakhala ndi moyo wautali wautumiki.Yesani luso limeneli pa matupi ng'anjo m'nyumba sanali ferrous zitsulo makampani.Kutentha kogwira ntchito kwa ng'anjo yozungulira kumafika 1200 ℃, ndipo kutentha kwa ng'anjo yosasunthika ndikokwera kwambiri mpaka 1000 ℃.Ng'anjo yozungulira imagwiritsa ntchito ng'anjo yovundukula ndi kudyetsa, ng'anjo yaying'ono ndi kuchotsa slag pamanja ndi zitseko zitatu za ng'anjo, ndipo ng'anjo yayikulu ndi ntchito yochotsa slag yokhala ndi zitseko ziwiri za ng'anjo.Zopangira zake ndi ma ingots a aluminiyamu, zitsulo zotayira, zolemba zakale ndi ma coil opangidwa ndi aluminiyamu.Ng'anjo iliyonse yosasunthika ilinso ndi zitseko ziwiri za ng'anjo ya slagging ndi kuyeretsa ntchito.M'mbuyomu, ng'anjo ya ng'anjoyo inkapangidwa ndi njerwa zowonongeka, ndipo mbali zina zinkawonongeka mosavuta, motero zimakhudza moyo ndi kupanga bwino kwa thupi la ng'anjo.Pomanga webusayiti ya Zhengzhou, ng'anjo yosungunuka ya aluminiyamu imatsanuliridwa pang'ono ndi zotayira zotayira kuti zithandizire moyo wonse wautumiki wa ng'anjo.
