Nruab nrab Carbon Ferro Manganese
Peb cov khoom muaj xws li nruab nrab carbon ferro manganese rau steel nroj tsuag, tsis tshua muaj carbonferro manganeserau hlau alloy, carbon ferro manganese thiab tsawg carbon ferro manganese rau steel kev lag luam.
Mn alloys feem ntau yog siv hauv steelmaking thiab foundry kev ua ub no. Qee qhov 30 feem pua ntawm cov manganese siv niaj hnub no hauv steelmaking tseem siv rau nws cov khoom ua deoxidant thiab sulfide qub. Nyob rau hauv rooj plaub kawg no nws ua ke nrog leej faj kom tsis txhob tsim cov hlau sulphides, uas sulphides yog qis melting point theem uas ua kua ntawm kub dov kub thiab uas, yog li ntawd, tsim nto tawg. Lwm 70 feem pua ntawm cov manganese yog siv los ua cov khoom siv hlau. Cov hlau feem ntau muaj los ntawm 0,2 feem pua mus rau 2 feem pua Mn nyob ntawm qib raws li Mn yog qhov pheej yig tshaj alloying cov khoom ntawm cov uas txhim kho qee qhov tseem ceeb ntawm cov khoom siv xws li lub zog thiab tawv. Hauv qhov tshwj xeeb ntawm cov hlau tsis muaj steel nws tuaj yeem hloov cov npib tsib xee kim hauv qee qib austenitic hu ua 200 series. Muaj ob tsev neeg ntawm Mn alloys hu ua ferro-manganese (FeMn) thiab silico-manganese (SiMn). Silico-manganese ntxiv silicon ntxiv uas yog lub zog deoxidizer thiab uas tseem yuav pab txhim kho qee yam khoom ntawm cov hlau. Hauv txhua tsev neeg cov pa roj carbon monoxide raug tswj thiab txo qis thaum tsim cov qib 'refined'. Nitrogen, Boron, Titanium, Phosphorus yog cov khoom uas tuaj yeem tswj tau raws li qhov xav tau tshwj xeeb. Ib daim ntawv thov tshwj xeeb ntawm refined manganese alloys yog ib qho tseem ceeb hauv txheej txheej ntawm vuam electrodes.
Manganese Oxide yog txo nyob rau hauv blast furnaces los yog hluav taws xob furnaces, Ferro Manganese yog tsim. Manganese ore nyob rau hauv lub xub ntiag ntawm carbon yog txo los tsim tus qauv ferro manganese los yog siab carbon ferro manganese. Nws muaj peev xwm rov ua dua slags rau hauv Ferro Silico Manganese, uas tuaj yeem rov ua kom zoo dua rau hauv qis thiab nruab nrab Carbon Ferro Manganese. Cov ntsiab lus ntawm manganese thiab carbon nyob rau hauv Ferro Manganese yog 75 feem pua thiab 7 feem pua. Cov variants ntawm Ferro Manganese yog High Carbon Ferro Manganese, Nruab Nrab Carbon Ferro Manganese thiab Tsawg Carbon Ferro Manganese.
Nruab nrab carbon ferro manganese yog siv los tsim E6013 electrodes. Tsis tas li ntawd, nws yog siv nyob rau hauv steel thiab casting industries, raws li nws pab tshem tawm cov sulfur ntawm hlau thiab txhim kho cov khoom, zoo li durability, machinability thiab malleability. Nws tuaj yeem deoxidize molten hlau. MOR lossis aluminothermic yog siv los tsim cov pa roj carbon ferro manganese nruab nrab.
