Qhia luv luv

Cov khoom siv raw yog stainless hlau ingots, siv lub qhov cub hluav taws xob uas yaj cov hlau tsis muaj steel ingots los ua 1500 ~ 1600 ℃ steel kua, thiab tom qab ntawd nrog kev kub ceev rotating melt-extracting steel log uas tsim cov xov hlau uas ua tau raws li peb cov neeg siv khoom tshwj xeeb. .Thaum melting mus rau lub log steel kua nto, cov kua hlau tshuab tawm los ntawm qhov nrog lub zog centrifugal ntawm kev kub ceev nrog kev ua kom txias.Melting log nrog dej ua kom txias ceev.Txoj kev tsim khoom no yooj yim dua thiab ua haujlwm tau zoo hauv kev tsim cov hlau fibers ntawm cov khoom sib txawv thiab ntau thiab tsawg.
