Kev tsim cov txheej txheem kho cua sov rau cov hlau saw hlau qib siab 23MnNiMoCr54
Kev kho cua sovtxiav txim siab qhov zoo thiab kev ua tau zoo ntawm cov hlau txuas puag ncig, yog li cov txheej txheem kho cua sov tsim nyog thiab ua haujlwm tau zoo yog ib txoj hauv kev zoo los xyuas kom meej tias cov hlau txuas zoo ruaj khov.
Cov txheej txheem ntawm kev kho cua sov ntawm 23MnNiMoCr54 qib siab saw hlau
Txoj kev siv cua sov induction nruab nrab muaj cov yam ntxwv ntawm kev kub ceev thiab tsawg dua oxidation, uas tsis yog tsuas yog ua raws li cov khoom ntsuab tam sim no, tab sis kuj ncav cuag qee qhov ntsuas ntawm lub zog thiab kev tawv ntawm cov hlau txuas saw hlau. Cov txheej txheem tshwj xeeb ntawm kev siv cua sov induction nruab nrab yog siv lub cub hluav taws xob induction nruab nrab ntawm cov khoom siv cua sov induction siab ua ntej, kom paub txog kev faib ntawm cov hlau txuas saw hlau quenching thiab tempering. Qhov kub quenching thiab tempering ua ntej cov saw hlau raug muab tso rau hauv hluav taws yog tswj hwm nruj me ntsis los ntawm kev ntsuas kub infrared. Los ntawm kev sim hauv kev xyaum, nws pom tias cov khoom siv txias rau quenching thiab tempering yog dej, Qhov kub ntawm dej raug tswj hwm hauv qab 30 ℃. Lub zog ntawm kev kub quenching yuav tsum tau tswj hwm ntawm 25-35kw, qhov ceev ntawm saw hlau yuav tsum tau tswj hwm ntawm 8-9hz thiab qhov kub yuav tsum tau tswj hwm ntawm 930 ℃ -960 ℃, yog li qhov nyuaj ntawm cov txheej tawv thiab saw hlau tuaj yeem ua tau raws li qee qhov kev xav tau zoo. Lub zog cua sov ntawm cov txheej txheem tempering yog tswj hwm ntawm 10-20kw thiab qhov kub yog tswj hwm ntawm 500 ℃ -550 ℃. Qhov ceev ntawm cov saw hlau yog tswj hwm ntawm 15 thiab 16Hz.
(1) Thaum pib ntawm kev ualub voj voog hlau txuas saw, txoj kev kho cua sov yog lub cub tawg radiant, xws li lub cub tawg rotary hearth. Lub cub tawg convection siv rau tempering. Txoj kev no xav tau lub sijhawm ua kom sov ntev thiab ua haujlwm tsawg, qee qhov kuj xav tau cov saw hlau ntev. Hauv tag nrho cov txheej txheem cua sov ntawm cov saw hlau, vim yog qib siab ntawm qhov chaw oxidation, nws nyuaj rau kom tau txais cov noob austenite zoo heev, uas thaum kawg ua rau qhov zoo ntawm cov saw hlau sib txuas uas tsim tawm thaum lub sijhawm ntawd. Nrog rau kev txhim kho tas mus li ntawm cov thev naus laus zis kho cua sov, txoj kev cua sov zaus nruab nrab induction tsim nyob rau theem tom qab tau siv dav, thiab qhov zoo ntawm kev kho cua sov ntawm cov saw hlau sib txuas tau zoo dua.
(2) Cov thev naus laus zis tempering saw, thawj zaug siv cov kub sib npaug tempering, tam sim no. kev txhim kho ntawm kev ruaj khov dua yog qhov nruab nrab zaus sib txawv kub tempering thiab sib npaug kub tempering ntxiv rau qhov sib txawv kub tempering. Qhov hu ua uniform kub tempering yog xav txog tias qhov nyuaj ntawm txhua qhov ntawm cov saw txuas yog tib yam tom qab tempering, tab sis cov saw txuas yog ua los ntawm kev vuam. Yog tias qhov kub tempering qis dhau, qhov sib koom ua ke vuam yooj yim tawg, thiab qhov nyuaj ntawm cov saw txuas 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 tias qhov kub tempering qis, qhov tawv ntawm cov saw kuj tseem yuav raug txo qis. Qhov sib txawv kub tempering siv induction cua sov, uas yog qhov tsim nyog dua rau cov xwm txheej cua sov ntawm cov saw, uas yog, sab saum toj ntawm lub xub pwg saw muaj qhov nyuaj siab thiab hnav tsis kam, thiab caj npab ncaj muaj qhov nyuaj tsawg thiab tawv zoo. Txoj kev kho cua sov no tuaj yeem txhim kho qhov zoo ntawm cov saw.
