Cov txheej txheem kho cua sov ntau zaus ntawm cov hlau tsis huv hauv chav ua noj siv cov khoom siv hluav taws xob ntau zaus rau quenching

Tsev riam stainless hlau hauv tsev xav tau kev ntse, tsis muaj chipping, tsis muaj curling, thiab tiv taus xeb. Yog li ntawd, peb feem ntau siv cov cuab yeej quenching ntau zaus los tua thiab kho cua sov stainless hlau chav ua noj riam kom tau raws li lawv cov kev xav tau ua haujlwm thiab txhim kho lawv cov tawv, hnav tsis kam thiab ua haujlwm lub neej. Niaj hnub no, peb txhua tus yuav los saib cov txheej txheem kho cua sov ntau zaus ntawm cov riam hauv chav ua noj stainless hlau. Rau

Stainless hlau chav ua noj riam yog ua los ntawm 3Cr13 lossis 4Cr13, thiab nws qhov ntev yog 180mmX80mmX2.5mm. Tom qab ntxhib sib tsoo rau 0.8-0.9mm, qhov txiav ntug raug rau induction quenching kev kho cua sov hauv lub tshuab ua kom sov ntau zaus. Tom qab quenching, cov kev xav tau hauv qab no tau ntsib: hardness 50-56HRC, thaj tsam hnyav ntau ≥25mm, kev faib khoom tsis sib xws, thiab deformation ≤2mm. Rau

1) Cov ntsuas hluav taws xob ntawm cov cuab yeej siv. Cov tswv yim hluav taws xob yog 380V, qhov hluav taws xob anode yog 7.5kV, qhov tam sim no anode yog 2.5A, lub tank hluav taws xob qhov hluav taws xob yog 5kV, daim phiaj tam sim no yog 0.6A, zaus yog 250kHz. Rau

2) Txheej txheem cua sov. Siv lub tshuab ua kom sov ntau zaus rau quenching. Tshwj xeeb inductors yuav tsum tau tsim. Cov riam hauv chav ua noj yuav tsum tau muab tso rau hauv qhov chaw haum rau qhov inductor. Induction cua sov ceev feem ntau yog 200-400 ℃/s. Cov austenitization tau ua tiav hauv ib qho tam sim yam tsis muaj kev khaws cia cua sov. . Qhov ntsuas cua sov ua kom sov yog 1050-1100 ℃, thiab cov dej txias yog roj. Tempering ntawm 200-220 ℃. Rau

Tsis pub dhau thaj tsam 180mm X25mm hauv thaj tsam tawv, tawv tom qab quenching thiab tempering yog tag nrho> 50HRC, thiab qhov tawv yog qhov sib xws. Txhua qhov ntsuas tuaj yeem ua tau raws cov kev xav tau. Rau

Raws li riam riam hauv tsev, stainless hlau chav ua noj riam tau siv dav. Yog li ntawd, yuav ua li cas txhawm rau txhim kho nws cov txheej txheem thiab kho cua sov yog qhov teeb meem uas txhua tus neeg tsim khoom xav txog. Hnub no, kab lus no tham txog txheej txheem kho cua sov ntau zaus ntawm cov riam hauv chav ua noj tsis huv, Kuv vam tias nws yuav muaj txiaj ntsig zoo rau txhua tus.
