Cov txheej txheem ntau lawm ntawm cov pa roj carbon tsawg thiab nruab nrab ferromanganese feem ntau suav nrog electrosilicon thermal method, rocker method thiab oxygen blowing method.

Dub silicon carbide yog tsim los ntawm quartz xuab zeb thiab roj av coke silica ua cov ntaub ntawv tseem ceeb los ntawm kev kub kub smelting nyob rau hauv lub qhov cub tsis kam. Nws hardness yog nruab nrab ntawm corundum thiab pob zeb diamond, nws lub zog txhua yam yog siab dua corundum, thiab nws yog nkig thiab ntse. Ntsuab silicon carbide yog tsim los ntawm roj av coke thiab silica raws li cov ntaub ntawv tseem ceeb, nrog ntsev ntxiv ua ib qho ntxiv, thiab smelted ntawm qhov kub thiab txias nyob rau hauv lub qhov cub tsis kam. Nws hardness yog nruab nrab ntawm corundum thiab pob zeb diamond, thiab nws lub zog txhua yam yog siab dua corundum.

Ferromolybdenum yog ib qho alloy ntawm molybdenum thiab hlau thiab yog siv los ua molybdenum additive hauv steelmaking. Ntxiv molybdenum rau hlau tuaj yeem ua rau cov hlau muaj cov qauv zoo-grained, uas tuaj yeem pab tshem tawm kev npau taws thiab txhim kho cov tawv tawv ntawm cov hlau. Hauv kev kub ceev hlau, molybdenum tuaj yeem hloov ib feem ntawm tungsten. Nrog rau lwm cov ntsiab lus alloying, molybdenum yog siv dav hauv kev tsim cov hlau tsis muaj cua sov, cov hlau tsis muaj zog, cov kua qaub-resistant steels thiab cov cuab yeej hlau, nrog rau cov hlau uas muaj lub cev tshwj xeeb. Ntxiv molybdenum rau cam khwb cia hlau tuaj yeem ua rau nws lub zog thiab hnav tsis kam. Ferromolybdenum feem ntau yog smelted los ntawm hlau thermal txoj kev.

Ferromolybdenum yog ib qho amorphous hlau additive nyob rau hauv cov txheej txheem ntau lawm thiab muaj ntau yam zoo heev uas tau pauv mus rau zinc alloys. Qhov txiaj ntsig tseem ceeb ntawm ferromolybdenum alloy yog nws cov khoom siv tawv tawv, uas ua rau cov hlau weldable. Cov yam ntxwv ntawm ferromolybdenum ua rau nws yog ib txheej ntxiv ntawm kev tiv thaiv zaj duab xis ntawm lwm cov hlau, ua rau nws haum rau ntau yam khoom.

Titanium yog ib qho ntawm cov hlau sib zog thiab tsis tshua muaj zog nrhiav tau tam sim no, thaum stainless hlau yog hlau-carbon alloy. Ntxiv mus, titanium alloy yog zoo dua li stainless hlau nyob rau hauv cov nqe lus ntawm kev ua tau zoo. Nws yog lub teeb hauv qhov hnyav thiab siab hardness. Nws cov oxidation tsis kam (uas yog, xeb) zoo ib yam li cov hlau tsis muaj steel, tab sis tus nqi sib raug zoo dua qub.

Hlau silicon 200 mesh yog nyiaj grey nrog nws cov luster. Nws muaj lub siab melting point, zoo kub tsis kam, siab resistivity thiab siab oxidation kuj.
