Case Hardening vs. Induction Hardening – Kev Sib Piv
Yog hais tias ib tug piv ob txoj kev rau hardening steel workpieces (rau ib tug dav piav qhia ntawm hardening saib ntawm no: Hardening), ces thawj striking sib txawv yog cov khoom tuav. Thaum cov ntaub ntawv hardening txheej txheem ntau ntawm workpieces tib lub sijhawm, induction hardening tsom rau ntawm tus kheej workpiece. Nrog induction hardening, cov khoom yog hardened workpiece los ntawm workpiece. Rau cov ntaub ntawv hardening, "batch by batch" yuav yog qhov kev piav qhia zoo dua.
Ntawm chav kawm, qhov no muaj kev cuam tshuam rau kev tsim khoom. Thaum cov ntaub ntawv hardening cia siab rau qhov chaw logistics los nqa qhov chaw ntawm cov kab ntau lawm thiab hardening, induction hardening pas nrig lossis raj tuaj yeem ua ke ncaj qha rau hauv cov kab ntau lawm nrog lub tshuab hardening tsim nyog (xws li MIND series) thiab yog ib feem ntawm lub voj voog.
Case hardening nthuav dav
Raws li tau hais los saum no, cov ntaub ntawv hardening yog ua nyob rau hauv batch. Raws li nrog induction hardening, lub hom phiaj yog kom tawv txheej txheej ntawm workpieces.
Thaum hardening lub workpieces yog hardened los ntawm carburization. Cov hlau yog rhuab mus rau 880 degree los ua austenitic. Tom qab ntawd cov thee hloov mus rau hauv ib feem los ntawm CO-emitting nruab nrab los ntawm ib feem ntawm qhov chaw. Lub diffusion ua rau ntug ntawm lub workpiece kom tau txais cov pa roj carbon ntau dua, thaum cov pa roj carbon density tseem zoo ib yam mus rau qhov chaw.
Hardening tshwm sim tom qab siv cov pa roj carbon. Kev nkag mus ntawm carbon yog qhov tseem ceeb rau qhov hardness thiab qhov tob hardness yam ntxwv ntawm workpiece. Lub hardening, piv txwv li lub hardness thiab hardening qhov tob, yog txhais los ntawm cov carbonization qhov tob, lub receptiveness thiab yog li lub hardenability ntawm cov hlau, thiab lub quenching. Qhov ntau carbon nyob rau hauv ib cheeb tsam ntawm lub workpiece, qhov ua tau zoo ntawm hardening nyob rau hauv cheeb tsam ntawd. peb tuaj yeem ua induction hardened chrome plated pas nrig.
Tom qab hardening, lub workpieces yog annealed los kho ib co ntawm lawv cov plasticity. Lub hom phiaj ntawm cov txheej txheem hardening yog ua kom cov ntug resistant rau txhua yam loads thaum muab ib feem txaus elasticity deflect sab nraud rog yam tsis muaj kev puas tsuaj.
Induction hardening nthuav dav
Raws li tau hais los saum toj no, txhua qhov yog hardened nyias nrog induction hardening tshuab. Txhua feem yog kho cua sov, quenched, thiab annealed (yog tias tsim nyog) cais. Ntxiv nrog rau kev sib koom ua ke hauv cov kab ntau lawm, qhov zoo ntawm induction hardening yog kev tswj xyuas meej thiab rov tsim dua ntawm cov txiaj ntsig hardening. Txhawm rau ua tiav qhov no, tag nrho cov txheej txheem hardening los ntawm inductor thiab siv lub zog thiab zaus rau quenching thiab annealing yog tshwj xeeb rau cov khoom ua haujlwm. Qhov no yields zoo heev hardening tshwm sim, txawm rau workpieces nrog complex geometry.
Peb muaj peev xwm muab qhov zoo tshaj plaws hard chrome rods thiab chrome tuav rau peb cov neeg muas zaub. Yog tias koj txaus siab rau peb cov chrome plated tuav, tawv chrome pas nrig, induction hardened chrome tuav, tiv tauj peb txhua lub sijhawm koj xav tias dawb.
