Kev kho cua sov ntawm cov hlau yog cov txheej txheem uas cov hlau ua haujlwm yog rhuab mus rau qhov ntsuas kub kom haum rau hauv ib qho nruab nrab, thiab tom qab ntawd txias ntawm qhov sib txawv ntawm qhov nrawm tom qab khaws cia BAI nyob rau hauv qhov kub thiab txias rau ib lub sijhawm. Cov txheej txheem tseem ceeb hauv kev tsim khoom, piv nrog rau lwm cov txheej txheem ua, kev kho cua sov feem ntau tsis hloov cov duab ntawm lub workpiece thiab tag nrho cov tshuaj muaj pes tsawg leeg, tab sis los ntawm kev hloov cov microstructure sab hauv ntawm lub workpiece, los yog hloov cov tshuaj muaj pes tsawg leeg ntawm lub workpiece nto. , muab los yog txhim kho cov kev ua tau zoo ntawm lub workpiece.Nws yog tus cwj pwm los ntawm kev txhim kho qhov zoo ntawm lub workpiece, uas feem ntau tsis pom ntawm qhov muag liab qab.In thiaj li yuav ua rau cov hlau workpiece muaj qhov yuav tsum tau muaj txhua yam khoom, lub cev thiab tshuaj. cov khoom, ntxiv rau kev xaiv cov khoom tsim nyog thiab ntau yam txheej txheem, kev kho cua sov yog feem ntauQhov tseem ceeb. Hlau thiab hlau yog cov khoom siv dav siv hauv kev lag luam machinery, cov txheej txheem microstructure ntawm hlau tuaj yeem tswj tau los ntawm kev kho cua sov, yog li kev kho cua sov ntawm cov hlau yog cov ntsiab lus tseem ceeb ntawm kev kho cua sov hlau. Tsis tas li ntawd, txhuas, tooj liab, magnesium, titanium thiab lawv cov alloys kuj tuaj yeem hloov pauv los ntawm kev kho cua sov ntawm lawv cov khoom siv tshuab, lub cev thiab tshuaj lom neeg, txhawm rau kom tau txais kev ua haujlwm sib txawv.
Kev kho cua sov muaj xws li annealing, tempering, hardening thiab tempering.
●Annealing: tuaj yeem txo qhov hardness ntawm cov ntaub ntawv hlau, tshem tawm kev sib cais, sib xyaw ua ke, txhim kho cov qauv tsis xws luag hauv casting, dov, forging thiab vuam txheej txheem; Kho cov nplej, txhim kho cov khoom, thiab npaj cov qauv zoo rau kev kho cua sov kawg; Txo hardness, txhim kho. kev ua tau zoo; Tshem tawm kev ntxhov siab sab hauv, ruaj khov thiab txo qis deformation thiab tawg.
●Normalizing: tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov pa roj carbon tsawg, tuaj yeem kho cov nplej, txhim kho cov khoom siv kho kom zoo.
●Quenching: txhim kho hardness, hnav tsis kam, txhim kho elasticity, txhim kho lub zog thiab toughness;
●Tempering: txhawm rau txo thiab tshem tawm cov kev ntxhov siab sab hauv ntawm cov hlau tawv tawv.Stabilize cov qauv thiab qhov loj me.
