Kub Muag Steelmaking Manganese Silicon SiMn Alloy

Silicomanganese yog ib qho kev sib xyaw ua ke los ntawm kev sib xyaw ntuj ntawm silicon thiab manganese, ib yam khoom uas tshwm sim hauv ntiaj teb. Ua ke, cov ntsiab lus no yog siv los tsim ntau yam tshwj xeeb steel alloys. Qhov sib xyaw no txhim kho cov khoom ntuj tsim ntawm cov hlau, muab nws lub zog thiab kev ua haujlwm, nrog rau kev zoo nkauj zoo nkauj. Qhov no txhais tau tias cov hlau no tuaj yeem siv rau hauv cov ntawv thov tshaj li cov khoom siv hlau. Silicon manganese tseem tuaj yeem hu ua ferrosilicon manganese lossis tsuas yog SiMn.

Cov tshuaj no tuaj yeem siv ib leeg lossis ua ke nrog lwm cov tshuaj los tsim ntau yam alloys. Qhov piv ntawm silicon rau manganese kuj tuaj yeem hloov kho kom muab cov hlau xav tau. Txheem silicon-manganese hlau alloys muaj 14 mus rau 16 feem pua ​​​​silicon, thiab mus txog 68 feem pua ​​​​ntawm manganese. Lawv kuj suav nrog me me ntawm cov pa roj carbon monoxide, uas yog tsim nyog rau cov hlau kom muaj tshuaj lom neeg nrog cov tshuaj no. Hauv cov hlau tsis muaj steel lossis cov khoom siv tshwj xeeb steel, cov ntsiab lus silicon tuaj yeem siab li 30%.

Ntxiv silicomanganese rau cov hlau kuj tsim kom muaj cov hlau ua kom huv, huv si. Cov tshuaj no nqus cov ntsiab lus ntuj xws li phosphorus los ntawm cov hlau. Qhov no txhais tau tias tsawg impurities thiab cov khoom zoo dua. Alloys ua los ntawm kev siv thev naus laus zis no siv sijhawm ntev dua thiab raug nqi ntau dua los tsim dua li cov hlau.
