Hluav taws xob arc rauv steelmaking, tseem hu ua short-process steelmaking, yog ib txoj kev smelting uas siv hluav taws xob cua sov. Nws ntiav cov hlau molten, seem steel, lossis Direct Reduced Iron ua cov khoom siv los tsim cov hlau tshwj xeeb zoo, tuav txoj haujlwm tseem ceeb hauv kev tsim cov hlau niaj hnub.
1. Cov yam ntxwv ntawm hluav taws xob arc rauv steelmaking
Kub kub thiab tswj tau yooj yim.Cov pa hluav taws xob hloov pauv tsuas yog tso siab rau lub cev thiab tshuaj cua sov ntawm cov hlau molten kom kub, thaum lub tshuab hluav taws xob arc rauv siv hluav taws xob cua sov, uas tuaj yeem tsis tsuas yog yaj ntau yam siab melting point alloys, tab sis kuj ceev thiab raug kub, nrog rau thermal efficiency. ntau tshaj 65%;
EAF tuaj yeem tsim kom muaj cua txias.Piv nrog rau qhov muaj zog oxidizing tej yam kev mob ntawm kev sib xyaw tshuab converter, hluav taws xob arc rauv tuaj yeem ntxiv cov khoom siv los txo cov cua, uas muaj txiaj ntsig zoo rau kev deoxidation thiab desulfurization, thiab txo qhov kub ntawm cov khoom yooj yim oxidizable;
Cov cuab yeej siv tau yooj yim.Muab piv rau cov pa oxygen converters, nws yuav tsum tau nqis peev tsawg dua thiab nyob hauv thaj chaw me me. Lub tshuab hluav taws xob arc rauv siv hluav taws xob ntau, txog 500kW.h ib tuj hlau, thiab cov ntsiab lus nitrogen thiab hydrogen hauv cov hlau yog siab dua me ntsis (H=0.005-0.008%, N{ {4}}005-0.010%).
2. Ib txwm siv hluav taws xob arc rauv smelting txheej txheem
Cov txheej txheem oxidation smelting ib txwm yog lub hauv paus ntawm EAF steelmaking, thiab cov txheej txheem tseem ceeb suav nrog tsib theem: them, melting, oxidizing, txo, thiab tapping; Nyob rau hauv cov txheej txheem ntawm EAF steelmaking, peb theem ntawm melting, oxidizing, thiab txo tam sim no feem ntau hu ua "laus peb theem".
