Kev xav tau rau induction cua sov kho qhov chaw ntawm cov khoom siv hluav taws xob ntau zaus

1. Lub hardness ntawm induction hardened qhov chaw

Tom qab induction hardening ntawm hlau, qhov tau qhov chaw hardness tus nqi muaj kev sib raug zoo nrog cov ntsiab lus ntawm cov hlau. Noj 45 steel ua piv txwv, qhov nruab nrab HRC ntawm qhov hardness tiav tom qab induction hardening yog 58.5, thiab qhov nruab nrab HRC ntawm 40 steel yog 55.5.

2. Hardening cheeb tsam ntawm induction hardened qhov chaw

Lub hardened cheeb tsam ntawm induction hardened qhov chaw yog qhov ntau ntawm cov hardened cheeb tsam. Vim qhov tshwj xeeb ntawm induction cua sov, txhawm rau zam qee qhov quenching pov tseg, cov hauv qab no feem ntau yuav tsum tau txiav txim siab rau thaj tsam quenching:

Rau qhov quenched nto ntawm lub tog raj kheej, ib qho kev hloov chaw yuav tsum tau sab laug thaum kawg. Qhov kawg ntawm lub cylindrical ncej feem ntau muaj cov qauv chamfered. Qhov kawg no yuav tsum tawm ntawm 3-5 hli tsis-quenched cheeb tsam, uas feem ntau tsis cuam tshuam rau kev ua haujlwm ntawm quenched seem. Hardened los yog incompletely hardened hloov.

Lub hardened cheeb tsam yuav tsum muaj ib tug meej kam rau ua ntau yam. Lub induction hardened cheeb tsam yuav tsum muaj ib tug kam rau ua ntau yam xws li lub unwillingness ntawm machining. Yog tias cov xwm txheej ntawm kev tso cai siv, qhov kev zam no tuaj yeem tsim nyog loj dua.

3. Qhov tob ntawm hardened txheej ntawm induction hardened qhov chaw

Tam sim no induction hardened qhov chaw raug txiav txim siab raws li tus txheej txheem thoob ntiaj teb ISO3754 thiab lub teb chaws tus qauv GB / T5617-2005, thiab qhov zoo hardened txheej qhov tob yog txiav txim los ntawm kev ntsuas qhov hardness ntawm seem ntawm ib feem.
