Kub Atmosphere Kub FECRAL A1 AF Apm Resistance Hlau siv rau Cov Khoom Siv Hluav Taws Xob
Cov khoom no siv refined master alloy li raw khoom, sivhmoov metallurgytshuab
los tsim cov alloy ingots, thiab yog tsim los ntawm tshwj xeeb txias thiab kub ua thiab cua sov
kev kho mob. Cov khoom muaj qhov zoo ntawm qhov muaj zog oxidation tsis kam, zoo
corrosion kuj ntawm kub kub, me me creep ntawm electrothermal Cheebtsam, ntev kev pab cuam
lub neej ntawm qhov kub thiab txias me me ntawm kev hloov tsis kam. Nws yog tsim rau kub 1420 C,
siab zog ceev, corrosive cua, carbon cua thiab lwm qhov chaw ua hauj lwm.
Nws tuaj yeem siv rau hauv ceramic kilns, kub kub kho cua sov rauv, kuaj qhov cub,
electronic industrial furnaces thiab diffusion furnaces.
