REFRACTORIES RAU ELECTRIC ARC FURNACE
Peb muab ntau yam refractories rau hluav taws xob ARC FURNACE
Lub cub tawg lub cev ntawm lub tshuab hluav taws xob arc rauv yog nyob rau hauv cov duab ntawm lub teapot, uas yog cov hlau ua cov tshuaj tiv thaiv hlab ntsha. Lub tshuab hluav taws xob muaj lub tshuab hluav taws xob thiab lub tshuab hluav taws xob (lub qhov cub sab saum toj). Lub plhaub sab nraud ntawm lub qhov cub lub cev yog ua los ntawm steel phaj, thiab sab hauv yog qhov cub hauv ob sab phlu. Phab ntsa rauv yog tsim nrog magnesia cib (MgO) lossis chrome magnesia cib (Cr2O3, MgO). Hauv qab ntawm lub cub tawg yog nyob rau hauv cov duab ntawm lub phiab, thiab muaj ib txheej ntawm magnesia hlawv (ua si) ntawm cov av nplaum cib thiab magnesia cib. Cov kua qaub rau hauv ob sab phlu yog tsim nrog quartz cib (SiO2) thiab quartz xuab zeb. Ntxiv nrog rau cov kev cai yooj yim ntawm lub zog, kub tsis kam thiab kub rwb thaiv tsev, cov khoom siv hluav taws xob hauv lub tshuab hluav taws xob kuj tseem yuav tsum tau tiv thaiv cov tshuaj lom neeg ntawm slag, thermal poob siab ntawm kev hloov pauv sai hauv qhov cub kub, thiab kev sib tsoo ntawm cov nqi blocks thiab cov tshuab ua haujlwm.
