Hauv kev tsim thiab tsim cov txheej txheem ntawm cov motors, txhawm rau kom tau txais qee qhov kev ua tau zoo ntawm qee qhov chaw, cov txheej txheem kev kho cua sov qee zaum siv. Cov ntaub ntawv sib txawv, qhov sib txawv, thiab qhov kev ua tau zoo sib txawv yuav tsum muaj kev kho cua sov sib txawv.
1. Cov txheej txheem Annealing txheej txheem no yog ua kom sov cov khoom mus rau 30 mus rau 50 degrees saum toj no qhov tseem ceeb kub, ua kom sov rau ib lub sij hawm, thiab ces maj mam txias rau hauv chav tsev kub. Daim ntawv thov kev kho annealing yog los txhim kho cov qauv sab hauv thiab kev siv tshuab ntawm cov khoom siv; nce lub plasticity ntawm cov khoom thiab tshem tawm qee qhov kev ntxhov siab; rau cov khoom sib nqus, nws tuaj yeem tshem tawm nws cov kev ntxhov siab sab hauv, txhim kho kev sib nqus conductivity, thiab txo lub zog poob. Cov ntaub ntawv uas tuaj yeem ua tiav los ntawm cov txheej txheem no feem ntau suav nrog cam khwb cia hlau, cam khwb cia hlau, forged steel, tooj liab thiab tooj liab alloys, cov khoom siv hlau nplaum, cov pa roj carbon siab, hlau alloy thiab stainless hlau. welded qhov chaw ntawm lub cev muaj zog (xws li welded shafts, welded tshuab bases, welded kawg npog, thiab lwm yam) thiab liab qab tooj liab tuav ntawm lub rotor tag nrho cov yuav tsum tau undergo qhov tsim nyog annealing txheej txheem.
2. Cov txheej txheem quenching: Cov txheej txheem no yog ua kom sov cov khoom saum toj no qhov ntsuas kub tseem ceeb, ua kom sov sov rau ib lub sijhawm thiab tom qab ntawd txias sai sai. Qhov nruab nrab cua txias yuav yog dej, dej ntsev, roj txias, thiab lwm yam, thiab nws lub hom phiaj yog kom tau txais cov tawv tawv dua. Feem ntau yog siv los ua kom tau raws li qhov kev ua tau zoo ntawm qhov chaw uas yuav tsum tau tiv taus siab loads lossis hnav tsis kam. Induction cua sov quenching yog ib txoj hauv kev siv lub hauv paus ntsiab lus ntawm electromagnetic induction los ua kom muaj qhov cuam tshuam tam sim no ntawm qhov chaw ua haujlwm. Los ntawm cov nyhuv ntawm daim tawv nqaij ntawm alternating tam sim no, nto ntawm lub workpiece yog sai rhuab mus rau ib tug austenitized lub xeev, thiab ces txias sai heev los hloov cov qauv nto. Nws yog martensite lossis bainite, yog li txhim kho qhov tawv tawv, hnav tsis kam thiab qaug zog lub zog ntawm cov khoom ua haujlwm, thaum tuav lub siab toughness hauv nruab nrab. Txoj kev no feem ntau siv rau qhov chaw xws li shafts thiab gears los txhim kho lawv cov khoom siv kho tshuab. 3. Qhov ntsuas kub tseem ceeb ntawm kev kho cua sov Qhov ntsuas kub tseem ceeb hauv kev kho cua sov yog hais txog qhov kub ntawm cov qauv ntawm cov khoom siv hlau hloov, uas ua rau muaj kev hloov pauv tseem ceeb. Qhov kub tseem ceeb ntawm cov khoom siv hlau sib txawv kuj txawv. Qhov kub tseem ceeb ntawm kev kho cua sov ntawm cov hlau yog li 740 ° C, thiab qhov kub tseem ceeb ntawm cov hlau sib txawv kuj txawv; Qhov kub tseem ceeb ntawm stainless hlau yog qis dua, feem ntau qis dua 950 ° C; Qhov kub tseem ceeb ntawm kev kho cua sov ntawm aluminium alloy feem ntau nyob ib ncig ntawm 350 ° C; Qhov kub tseem ceeb ntawm tooj liab alloy Qhov ntsuas kub tseem ceeb yog qis, feem ntau qis dua 200 ° C.
