Qhov tseem ceeb ntawm Industrial Quenching furnaces hauv Manufacturing

Quenching furnaces ua lub luag haujlwm tseem ceeb hauv kev tsim khoom niaj hnub no, tshwj xeeb tshaj yog nyob rau hauv kev kho cua sov ntawm cov ntaub ntawv hlau. Los ntawm kev tswj hwm cov haujlwm xws li cua sov, tuav thiab ua kom txias txias ntawm cov hlau ua haujlwm, lawv hloov cov qauv sab hauv ntawm cov hlau, yog li txhim kho nws cov cuab yeej cuab tam thiab ua tau raws li cov kev cai nruj rau cov khoom siv zog, hardness, toughness thiab hnav tsis kam nyob rau hauv ntau yam kev ua haujlwm nyuaj.

Hom ntawm quenching rauv

Quenching furnaces tuaj nyob rau hauv ntau hom kom haum rau workpieces ntawm cov khoom sib txawv, qhov ntau thiab tsawg, thiab cov duab, nrog rau cov txheej txheem tshwj xeeb.

1. Lub thawv- hom quenching rauv:Qhov no yog hom ntau tshaj plaws. Nws cov qauv yog qhov yooj yim, nrog lub thawv -zoo li lub cub tawg chamber. Cov khoom ua haujlwm tau muab tso rau ntawm racks sab hauv lub qhov cub rau cua sov. Hom qhov cub no yog tsim rau quenching dav me me mus rau nruab nrab- qhov loj me ntawm cov hlau, xws li shafts, gears, thiab pwm. Nws muaj cov khoom sib khi zoo, tiv thaiv kom tsis txhob muaj cua sov thiab oxidation, thiab tseem pab tswj qhov kub thiab txias.

2. Pit-hom quenching rauv:Feem ntau yog siv los ua cov ncej ntev, cov pas nrig, thiab qee lub nplhaib loj - zoo li qhov chaw. Nws lub qhov cub lub cev yog zoo li lub qhov taub ntsug, nrog cov workpieces raug tshem tawm sab hauv. Cov khoom siv cua sov tshwj xeeb thiab cov tshuab ua haujlwm kom ntseeg tau tias cov cua sov sib npaug sib npaug mus rau txhua qhov chaw ntawm cov khoom ua haujlwm, ua tiav cov txiaj ntsig siab - zoo quenching.

3. Nruam quenching rauv:Ib qho khoom siv ua haujlwm siab heev uas ua rau muaj kev noj zaub mov tsis tu ncua, cua sov, quenching thiab unloading ntawm workpieces, zoo heev txhim kho efficiency. Nws yog tsim rau loj - nplai, txheem hlau qhov chaw tsim khoom, xws li kev sib dhos kab ua haujlwm hauv tsheb thiab cov kabmob kev lag luam. Nws txo cov kauj ruam ua haujlwm, txo cov nqi tsim khoom, thiab ua kom ruaj khov ntawm cov khoom zoo.

Txoj cai ua haujlwm

Lub hauv paus ntsiab lus ua haujlwm ntawm lub qhov cub quenching yog ua raws li theem kev hloov pauv ntawm cov khoom siv hlau.

1. Cua sov theem

* Cov hlau ua haujlwm yog rhuab mus rau qhov tsim nyog kub, ua rau nws cov qauv siv lead ua los hloov mus rau hauv austenite (siab-kub theem).

* Kev tswj xyuas qhov kub thiab txias thiab tuav lub sijhawm yuav tsum tau ua kom ntseeg tau tias cov khoom siv austenite tsis sib xws thiab zam qhov tsis xws li overheating thiab hlawv (uas yuav cuam tshuam rau cov khoom siv loj).

2. Lub caij txias

* Lub workpiece tau xa mus sai sai ntawm lub qhov cub cua sov mus rau qhov nruab nrab quenching kom txias.

* Kev xaiv nruab nrab quenching: Nyob ntawm cov khoom siv ua haujlwm thiab kev ua haujlwm, dej, roj, dej ntsev, lossis cov tshuaj tua hluav taws tshwj xeeb tuaj yeem xaiv tau (cov xov xwm sib txawv muaj peev xwm sib txawv).

* Cov nyhuv txias: ceev ceev ceev tiv thaiv austenite los ntawm decomposing thiab ncaj qha hloov nws mus rau hauv martensite thiab lwm yam quenched lug, muab lub workpiece siab hardness thiab siab zog.

3. Cov ntsiab lus tseem ceeb tswj

* Tus nqi cua txias yuav tsum tau tswj nruj me ntsis: tus nqi nrawm heev tuaj yeem ua rau cov khoom tawg yooj yim thiab deformation; qeeb qeeb tus nqi yuav tsis ua tiav qhov xav tau quenching nyhuv.

* Kev tsim thiab kev ua kom zoo ntawm cov quenching rauv qhov kev ua haujlwm tsis zoo yog qhov tseem ceeb rau kev ua kom quenching zoo.

Qhov zoo thiab qhov txwv

Qhov zoo ntawm quenching furnaces nyob rau hauv lawv lub peev xwm los txhim kho lub zog ntawm cov khoom siv hlau, muab cov khoom ua haujlwm siab dua, lub zog, tawv, thiab hnav tsis kam, yog li ua tau raws li qhov yuav tsum tau ua ntawm ntau yam kev ua haujlwm nyuaj thiab siab -load haujlwm. Nyob rau tib lub sijhawm, cov txheej txheem cua sov thiab cua txias ntawm lub tshuab hluav taws xob quenching tuaj yeem tswj tau thiab ua kom zoo dua los ntawm kev tswj xyuas qhov tseeb, ua tiav kev tswj xyuas nruj ntawm cov txheej txheem tsis zoo thiab ua kom muaj kev ruaj ntseg thiab zoo ib yam ntawm cov khoom zoo. Tsis tas li ntawd, quenching furnaces muaj ntau yam kev siv, muaj peev xwm ua cov hlau ua haujlwm ntawm ntau yam ntaub ntawv, qhov ntau thiab tsawg, thiab cov duab, muab cov kev hloov pauv siab thiab ntau yam.

Txawm li cas los xij, quenching furnaces kuj muaj qee qhov kev txwv. Thaum lub sij hawm quenching txheej txheem, cua txias ceev tau yooj yim tsim quenching kev ntxhov siab nyob rau hauv lub workpiece, ua rau muaj kev tsis xws luag xws li deformation thiab cracking. Cov kev tsis zoo no yuav tsum tau muab tshem tawm hauv kev kho cua sov tom ntej, ua rau kom qhov nyuaj thiab tus nqi ntawm cov txheej txheem. Tsis tas li ntawd, quenching furnaces muaj kev siv hluav taws xob ntau, tshwj xeeb tshaj yog thaum ua cov khoom loj, yuav tsum muaj ntau lub zog los ua kom sov thiab tswj qhov kub ntawm qhov cub, ua rau muaj teeb meem rau kev siv hluav taws xob thiab kev tswj xyuas cov nqi. Tsis tas li ntawd, kev khiav hauj lwm lub tshuab hluav taws xob quenching yuav tsum muaj cov kws tshaj lij tshwj xeeb, xav tau kev txawj ntse thiab kev paub dhau los ntawm cov neeg ua haujlwm. Kev ua haujlwm tsis raug yuav ua rau cov khoom seem lossis cov khoom puas tsuaj, cuam tshuam rau kev tsim khoom thiab cov khoom zoo.

Txawm hais tias cov kev txwv no, quenching furnaces ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv kev tsim khoom lag luam. Nrog kev txhim kho thev naus laus zis tsis tu ncua, quenching furnace thev naus laus zis tau hloov kho thiab txhim kho tas li. Piv txwv li, kev tsim kho tshiab quenching media, kev siv hluav taws xob-txuag thev naus laus zis, thiab kev txhim kho ntawm cov tshuab tswj tsis siv neeg yog txhua yam txuas ntxiv txhim kho kev ua tau zoo thiab kev ua haujlwm ntawm quenching furnaces, txo cov nqi tsim khoom thiab kev cuam tshuam ib puag ncig, muab kev txhawb zog rau kev tsim kho kev lag luam, thiab txhawb nqa cov ntaub ntawv hlau kub kho kev lag luam mus rau qib siab dua.
