Why is your steel plate induction heating not ideal?

Vim li cas koj steel phaj induction cua sov tsis zoo tagnrho? Hlau phaj induction cua sov cov cuab yeej tseem yuav cuam tshuam qhov kawg tshwm sim ntawm quenching thiab tempering.

Cov khoom siv kub dov uas tau quenched thiab tempered los ntawm nruab nrab zaus induction cua sov yog sai rhuab mus rau ib tug zoo heev martensite qauv tom qab quenching los ntawm austenite, thiab ces tempered ntawm kub kom tau zoo tempered sorbite. Qhov tempered sorbite no muaj lub zog tensile siab thiab lub zog tawm los, nrog rau cov duab zoo thiab toughness.

Hlau phaj induction cua sov quenching thiab tempering yog ib qho kev kho cua sov dual ntawm quenching thiab kub tempering, thiab nws lub hom phiaj yog ua kom cov workpiece muaj cov khoom zoo txhua yam.

Hlau phaj induction cua sov muaj ob pawg: carbon quenched thiab tempered steel thiab alloy quenched thiab tempered steel. Txawm hais tias nws yog carbon steel los yog hlau alloy, nws cov ntsiab lus carbon yog tswj nruj me ntsis. Yog tias cov ntsiab lus carbon siab dhau lawm, lub zog ntawm lub workpiece tom qab quenching thiab tempering yog siab, tab sis lub toughness tsis txaus. Yog tias cov ntsiab lus carbon tsawg dhau, qhov toughness yuav nce thiab lub zog yuav tsis txaus. Txhawm rau kom tau txais kev ua tau zoo ntawm cov quenched thiab tempered qhov chaw, cov ntsiab lus carbon feem ntau yog tswj ntawm 0.30 ~ 0.50%.

Lub zog ntawm cov khoom siv thiab kev teeb tsa ntawm cov khoom tseem ceeb yog txhua yam uas cuam tshuam rau lub tshuab hluav taws xob hluav taws xob hluav taws xob. Nws raug nquahu kom nrhiav ob peb lub tuam txhab ntxiv rau kev sib piv, koj tuaj yeem sab laj firstfurnace@gmail.com
