Feem ntau cov piston qws yog tsim los ntawm 40Cr steel. Kev khiav dej num tseem ceeb yog: forging, normalizing, machining (ntxhib), kev ntxhov siab ua kom tsaug zog, ua haujlwm (semi-finishing), quenching, tempering, thiab thaum kawg machining (nplua ua). Hauv kev lag luam ntawm cov khoom siv, pist pas nrig yog ib qho ntawm lub zog ntawm cov quab yuam, yog li nws yog qhov tsim nyog rau cua sov-kho 40Cr steel los txhim kho ntau yam khoom siv ntawm cov khoom kom tau raws li qhov kev xav tau tiag.
Hauv cov txheej txheem ntawm kev kho cua sov, kev ua haujlwm ua ntej yuav tsum tau ua kom yooj yim rau kev ua thiab muab cov khoom siv zoo thiab zoo hnav zoo. Txhawm rau tshem tawm cov kev ntxhov siab ntawm kev ua hauj lwm thiab tsis txhob ua cov kev ua rau tsis zoo, yuav tsum muaj kev nyuaj siab rau kev ntxhov siab. Tom ntej no, tus txheej txheem tseem ceeb ntawm txoj kev kho cua sov, kev ua haujlwm tawm thiab kev ua haujlwm ua haujlwm raug muab coj los txhawm rau txhim kho cov khoom sib txuas ntawm cov piston pas nrig.
Tom qab ntawd, qhov zoo ntawm piston pas nrig yuav tsum tau kuaj xyuas kom paub meej cov khoom zoo. Hauv kev xaus, raws li ib yam ntawm cov feem sib dhos, cov txheej txheem cua sov txheej txheem ntawm piston pas nrig 40Cr steel tau soj ntsuam. Los ntawm kev sib piv ntawm kev ua tau zoo nyob rau hauv ntau yam, lub sub-kub quenching tshav kub kho tau zoo txhim kho cov kev ua tau zoo ntawm cov khoom.http: //www.xhychromerod.com/
