Calcium Silicon Cored Hlau Rau Hloov Steelmaking

Calcium Silicon Cored Hlau rau Converter Steelmaking yog ib qho tseem ceeb tsis tau siab -kawg metallurgical khoom nyob rau hauv converter steelmaking thiab ladle refining txheej txheem. Siv high-purity calcium silicon alloy hmoov ua cov khoom siv tseem ceeb, nws tau raug qhwv thiab dov los ntawm siab -zoo qis- carbon txias- dov steel strip. Los ntawm cov xaim feeder, nws raug pub kom nkag mus tob rau hauv cov hlau molten, daws teeb meem xws li oxidation hnyav thiab volatilization, tsis tshua muaj txiaj ntsig, thiab tsis ruaj tsis khov metallurgical teebmeem cuam tshuam nrog cov tsoos blocky calcium silicon alloys.

Q1: Vim li cas silicon-calcium cored hlau nyiam rau converter steelmaking es tsis txhob blocky silicon-calcium alloy?

A1: Tom qab tapping los ntawm lub converter, molten steel kub yog siab, thiab cov ntsiab lus oxygen thiab sulfur siab. Ntxiv blocky silicon-calcium alloy yooj yim ua rau oxidation sai thiab volatilization, uas ua rau cov calcium uas tsis tshua muaj, tsis ruaj tsis khov metallurgical teebmeem, thiab cov plua plav tseem ceeb. Silicon-calcium cored hlau, qhwv nrog steel sawb, tuaj yeem raug pub rau hauv cov txheej sib sib zog nqus ntawm cov hlau molten, tiv thaiv calcium oxidation, ua kom cov qoob loo ntau dua 100%, thiab muab cov txiaj ntsig zoo metallurgical. Nws kuj ua kom yooj yim rau kev khiav lag luam thiab txo cov nqi, ua rau nws nyiam cov khoom siv rau siab -kawg converter steelmaking.

Q2: Yuav ua li cas xaiv ntawm Ca28Si60 thiab Ca30Si60 qib?

A2: Ca30Si60 muaj cov ntsiab lus calcium ntau dua, ua rau muaj zog deoxidation thiab desulfurization cuam tshuam, ua rau nws tsim nyog rau kev tsim cov qib siab -kawg steels xws li qis- carbon steel, ultra- low- sulfur steel, pipeline steel, thiab automotive steel. Ca28Si60 muaj cov nqi zoo dua{10}}kev ua tau zoo, nrog rau kev deoxidation thiab desulfurization cuam tshuam txaus rau kev tsim cov pa hlau xws li cov pa roj carbon steel thiab qis{11}} alloy steel. Qhov kev xaiv nyob ntawm koj qhov kev xav tau tshwj xeeb steel thiab cov nqi siv nyiaj.

Q3: Yuav ua li cas yog cov hlau pub tus nqi precisely tswj? Koj puas muab kev txhawb nqa?

A3: Tus nqi pub hlau yog txiav txim siab raws li qhov kawg ntawm cov pa oxygen thiab sulfur cov ntsiab lus ntawm cov hlau molten, qib steel, thiab cov nqi hluav taws xob. Tus qauv tus nqi yog 0.8-1.5 kg / t ntawm hlau, uas tuaj yeem hloov kho rau 1.5-2.0 kg / t ntawm cov hlau hauv qhov sib sib zog nqus desulfurization scenarios. Peb yuav npaj cov kws tshaj lij metallurgical engineers los muab cov txheej txheem meej xws li xaim pub tus nqi thiab pub ceev raws li koj cov kev hloov pauv thiab qib steel, muab kev qhia tag nrho thiab pab koj hauv kev ua kom koj cov txheej txheem steelmaking.
