Ua ib lub tuam txhab muag khoom tshwj xeeb hauv cov hlau ua tau zoo, peb kuj muab cov hlau puag ncig zoo uas tsis tau quenched thiab tempered nrog cov khoom siv 45MnVS. Cov no yog tsim los ntawm cov txheej txheem meej thiab ua tau raws li cov qauv siab ntawm kev lag luam. Cov lus qhia ntawm cov khoom muaj ntau yam, suav nrog cov hlau puag ncig 20mm mus rau 160mm hlau puag ncig uas xav tau rau kev lag luam hnyav, thiab tuaj yeem siv dav hauv kev tsim cov khoom siv siab xws li piston rods thiab ntau yam khoom siv ncej.
Peb likub dov alloy steel puag ncig tuav muaj cov yam ntxwv zoo tshaj plaws hauv qab no:
Lub zog thiab kev tawv ua ke: Haum rau kev tiv taus cov khoom thauj siab thiab kev co;
Kev siv tshuab tau zoo: Txhawb ntau yam txheej txheem machining xws li tig, milling, thiab drilling;
Kev ruaj khov ntawm qhov ntev: Cov txheej txheem kub dov ua kom cov qauv khoom sib xws, txo qhov kev pheej hmoo ntawm kev hloov pauv thaum lub sijhawm kho cua sov tom qab.
Kev siv tau dav: Npog ntau yam xws li cov khoom siv hluav taws xob, cov tshuab tsim kho, kev tsim khoom tsheb, thiab cov khoom siv hnyav.
Txawm yog kev yuav khoom ntau lossis kev cai tshwj xeeb, peb tuaj yeem muab cov hlau sib xyaw zoo uas ua tau raws li cov qauv thoob ntiaj teb xws li 45CrMo4, 8620, thiab 4340. Peb kuj tuaj yeem kho cov khoom raws li cov neeg siv khoom kos duab thiab cov lus qhia tshwj xeeb, pab cov tuam txhab txhim kho kev sib tw ntawm cov khoom thiab luv lub voj voog tsim khoom.
