Cov yam ntxwv tseem ceeb ntawm induction melting rauv smelting

Induction melting rauv thiab hluav taws xob arc rauv smelting txoj kev muaj lawv tus kheej cov yam ntxwv sib txawv, yog li nws yog ib qho nyuaj rau kev hloov ib leeg, tab sis muab tag nrho cov kev ua si rau lawv cov kev zoo, txais yuav los yog koom tes nrog rau hauv zos tej yam kev mob kom ua tau zoo.

Table 4-1 Cov yam ntxwv tseem ceeb ntawm induction melting rauv melting (piv nrog cov hluav taws xob zoo tib yam arc rauv)

Serial tooj	Sib piv cov ntsiab lus	Hluav taws xob arc rauv	Induction melting rauv
1	Cua sov txoj kev	Tus nqi hlau yog rhuab, melted, thiab refined nyob rau hauv qhov ncaj qha kev txiav txim ntawm graphite electrode siab kub arc, thiab lub ntsiab muaj volatilization, oxidation poob thiab carbon nce.	Nyob rau hauv qhov kev txiav txim ntawm induction magnetic teb, tus nqi hlau generates eddy tam sim no, uas yog rhuab, melted thiab refined (tsis tiv tauj cua sov) los ntawm kev tiv thaiv tshav kub, thiab kub yog yooj yim los tswj. Element volatilization thiab oxidation poob yog me me, thiab alloy rov qab tus nqi siab
2	Slagging tej yam kev mob	Lub molten steel tshav kub qhov chaw ntawm high-temperature arc yog ncaj qha nyob rau hauv kev sib cuag nrog lub slag, thiab qhov kub ntawm lub molten slag yog yuav luag tib yam li cov hlau molten.	Lub slag yog yaj los ntawm tshav kub ntawm cov hlau molten, yog li lub slag kub yog qis dua li ntawm cov hlau molten. Nws belongs rau “txias slag” (hais lus hais), thiab nws cov fluidity thiab cov tshuaj tiv thaiv muaj peev xwm phem dua li hluav taws xob arc rauv slag.
3	Stirring tej yam kev mob ntawm molten hlau	Kev cia siab rau kev ntxhov siab ntawm lub pas dej molten tsim los ntawm cov tshuaj tiv thaiv decarburization los tsim cov co, lub peev xwm denitrification yog qhov phem tshaj qhov ntawm induction melting rauv.	Kev cia siab ntawm electromagnetic stirring ua kom qhov kub thiab muaj pes tsawg leeg ntawm molten steel uniform, nrog zoo degassing (N2) muaj peev xwm vim zoo stirring
4	Metallurgical muaj nuj nqi	Kev tshem tawm ntawm oxidation ntawm C, de P, nrog rau kev txo qis ntawm slag S, raw khoom tuaj yeem so kom txaus.	Tsis muaj kev ua haujlwm ntawm kev tshem tawm C thiab tshem tawm P thiab S (tsis muaj kev ntsuas tshwj xeeb), thiab cov khoom siv raw khoom hnyav
