Ferro manganese yog ib hom hlau alloy feem ntau yog tsim los ntawm manganese thiab hlau. Cov khoom siv tshuaj manganese muaj ntau dua li cov hlau.Thaum ntxiv cov manganese rau molten steel, nws tuaj yeem hnov mob nrog ferrous oxide los ua cov oxide slag uas yog insoluble hauv molten. steel, lub slag ntab ntawm lub molten steel nto, txo cov pa oxygen nyob rau hauv cov hlau, tib lub sij hawm, lub binding quab yuam ntawm manganese thiab sulfur yog ntau tshaj lub binding quab yuam ntawm hlau thiab sulfur, tom qab ntxiv cov manganese alloy, cov sulfur. Nyob rau hauv lub molten hlau yog ib qho yooj yim los tsim ib tug siab melting point manganese alloy, cov sulfur nyob rau hauv lub molten hlau yog ib qho yooj yim los tsim ib tug siab melting point manganese sulfide nrog manganese thiab hloov mus rau hauv lub cub tawg slag, yog li txo cov sulfur cov ntsiab lus nyob rau hauv lub molten hlau thiab Kev txhim kho lub forgeability thiab rollability ntawm steel.Manganese kuj yuav ua rau kom lub zog, hardenability, hardness thiab hnav tsis kam ntawm cov hlau.Yog li cov ferro manganese feem ntau siv raws li deoxidizer, desulfurizer thiab alloy additive nyob rau hauv steel ua thiab uas ua rau nws siv ntau tshaj hlau. hlau alloy.
