Kev txhim kho cov txheej txheem kev kho cua sov rau qib siab saw hlau 23MnNiMoCr54
Kev kho cua sovtxiav txim siab qhov zoo thiab kev ua tau zoo ntawm cov kab txuas txuas hlau, yog li tsim nyog thiab siv tau cov txheej txheem kho cua sov yog ib txoj hauv kev zoo los xyuas kom muaj kev ruaj ntseg zoo ntawm qib high-qib saw hlau.
Cov txheej txheem ntawm kev kho cua sov ntawm 23MnNiMoCr54 qib siab saw hlau
Qhov nruab nrab zaus induction cua sov txoj kev muaj cov yam ntxwv ntawm cov cua kub ceev ceev thiab tsawg oxidation, uas tsis tsuas yog ua raws li cov khoom ntsuab tam sim no, tab sis kuj nce mus txog qee qhov ntsuas ntawm cov kab hlau txuas txuas lub zog thiab toughness.Cov txheej txheem tshwj xeeb ntawm kev siv qhov nruab nrab zaus induction cua sov kho yog los txais yuav qhov nruab nrab zaus induction nruam rauv ntawm high-power induction cua sov cov khoom ua ntej, kom paub txog kev faib ntawm puag ncig steel txuas saw quenching thiab tempering.Lub quenching thiab tempering kub ua ntej cov saw yuav muab tso rau hauv hluav taws yog nruj me ntsis tswj los ntawm infrared ntsuas kub.Los ntawm kev sim hauv kev xyaum, nws pom tias qhov nruab nrab cua txias rau quenching thiab tempering yog dej, Cov dej kub tswj tau qis dua 30 ℃.Lub zog ntawm quenching cua sov yuav tsum tau tswj ntawm 25-35kw, cov saw ceev yuav tsum tau tswj ntawm 8-9hz thiab kub yuav tsum tau tswj ntawm 930 ℃ -960 ℃, yog li ntawd lub hardness ntawm hardened txheej thiab saw muaj peev xwm ua tau raws li tej yam kev cai. .Lub zog cua sov ntawm cov txheej txheem tempering yog tswj ntawm 10-20kw thiab kub tswj ntawm 500 ℃ -550 ℃.Cov saw ceev yog khaws cia ntawm 15 thiab 16Hz.
(1) Nyob rau theem pib ntawm kev uaround steel txuas saw, txoj kev kho cua sov yog radiant rauv, xws li rotary hearth rauv.Lub convection rauv yog siv rau tempering.Txoj kev no xav tau lub sijhawm cua sov ntev thiab kev ua haujlwm qis, qee qhov tseem xav tau cov saw hlau ntev ntev.Nyob rau hauv tag nrho cov txheej txheem cua sov ntawm cov saw, vim lub high degree ntawm oxidation nto, nws yog ib qhov nyuaj kom tau zoo heev austenite nplej, uas nws thiaj li ua rau lub dav dav zoo ntawm lub round steel txuas saw tsim nyob rau lub sij hawm ntawd.Nrog rau kev txhim kho txuas ntxiv ntawm kev kho cua sov thev naus laus zis, qhov nruab nrab zaus induction cua sov txoj kev tsim nyob rau theem tom qab tau siv dav, thiab kev kho cua sov zoo ntawm cov kab hlau txuas txuas tau zoo tuaj.
(2) Chain tempering thev naus laus zis, kev siv thawj zaug ntawm qhov ntsuas kub tsis sib xws, qhov tam sim no.txoj kev loj hlob ntawm ntau ruaj khov yog qhov nruab nrab zaus sib txawv kub tempering thiab uniform kub tempering ntxiv rau qhov sib txawv kub tempering.Qhov sib txawv ntawm qhov kub thiab txias yog xav txog tias qhov hardness ntawm txhua feem ntawm cov saw txuas yog tib yam tom qab tempering, tab sis cov saw txuas yog tsim los ntawm vuam.Yog tias qhov kub thiab txias qis dhau lawm, qhov sib txuas vuam yog ib qho yooj yim rau tawg, thiab cov saw txuas hardness siab, kev sib txhuam ntawm sab nraud ntawm caj npab ncaj thiab qhov nruab nrab ntawm lub conveyor kuj yooj yim heev los tsim cov kab nrib pleb.Yog hais tias qhov kub thiab txias yog tsawg, lub toughness ntawm cov saw kuj yuav txo tau.Qhov sib txawv ntawm qhov kub thiab txias tau txais cov cua sov induction, uas yog qhov tsim nyog rau cov cua sov ntawm cov saw hlau, uas yog, sab saum toj ntawm lub xub pwg saw muaj siab hardness thiab hnav tsis kam, thiab ncaj caj npab tsis tshua muaj hardness thiab zoo toughness.Txoj kev kho cua sov no tuaj yeem txhim kho qhov zoo ntawm cov saw hlau.
