Kev siv ntawm Manganese Ingot
Lub luag haujlwm tseem ceeb ntawm manganese ingots hauv steelmaking yog deoxidation, desulfurization thiab alloying ntsiab.
(1) Siv los ua deoxidizer
Hlau muaj cov kev cai nruj rau cov ntsiab lus oxygen, feem ntau tsis ntau tshaj 0.02%, lossis tseem nruj dua. Yog li ntawd, cov pa ntau dhau raug tshem tawm thaum lub sij hawm steelmaking txheej txheem. Manganese yog ib hom khoom siv hlau, thiab nws cov khoom siv tshuaj muaj zog ntau dua li hlau. Thaum manganese ntxiv rau molten steel, manganese yuav hnov mob nrog ferrous oxide los ua oxidized slag uas yog insoluble nyob rau hauv molten steel, thiab oxidized slag ntab rau saum npoo ntawm cov hlau molten kom txo cov pa oxygen hauv cov hlau.
(2) Siv los ua desulfurizer
Sulfur yog tam sim no nyob rau hauv molten hlau nyob rau hauv daim ntawv ntawm hlau sulfide. High sulfur cov ntsiab lus nyob rau hauv cov hlau yog nquag kub embrittlement thiab txo cov neeg kho tshuab zog ntawm hlau. Yog li ntawd, cov ntsiab lus sulfur yuav tsum tau tswj nyob rau hauv cov txheej txheem steelmaking. Lub zog khi ntawm manganese thiab sulfur yog ntau dua li ntawm hlau thiab sulfur. Tom qab ntxiv manganese alloy, siab melting point manganese sulfide yog yooj yim generated ua ke nrog manganese nyob rau hauv molten steel thiab hloov mus rau hauv slag, li no yuav txo tau cov sulfur ntsiab lus nyob rau hauv steel thiab txhim kho lub forgeability thiab rollability ntawm hlau.
(3) Raws li cov khoom siv alloying
Manganese tuaj yeem ntxiv dag zog rau ferrite thiab ua kom zoo dua pearlite, txhim kho lub zog, hardenability, hardness thiab hnav tsis kam ntawm cov hlau, yog li nws tuaj yeem dhau los ua ib qho tseem ceeb alloying ntawm ntau yam hlau. Piv txwv li, yog tias 0.8%-1.7% manganese ntxiv rau cov hlau tsis tshua muaj hlau, lub zog ntawm cov hlau tuaj yeem nce 20% -30% piv rau cov pa roj carbon zoo tib yam. hlau.
