Nqa Roj Lub tog raj kheej txhawb nqa

Peb muaj kev paub dhau los hauv kev tsim hydraulic lub tog raj kheej txhawb nqa. Cov khoom siv casting tuaj yeem ua kom zoo raws li cov neeg siv khoom sib txawv. Tom qab multi-theem kev kho cua sov (quenching + siab -temperature tempering), lub hauv paus cov ntaub ntawv hardness ncav cuag HB 280-320, thiab lub tensile zog yog ntau tshaj los yog sib npaug rau 850MPa, uas ua rau kom lub load{11}} bearing muaj peev xwm los ntawm 40% piv nrog cov pa roj carbon steel qhov chaw. Peb nruj me ntsis ua raws li ASTM A148 tus qauv rau kev tswj cov tshuaj muaj pes tsawg leeg kom ntseeg tau tias qhov kub thiab txias cuam tshuam toughness (-40℃KV2 Ntau dua lossis sib npaug rau 27J) thiab weld compatibility. Peb kuj muaj peev xwm rau precision machining. Peb siv ntau yam khoom siv xws li kev sib koom tes ntsuas tshuab, metallographic microscope, magnetic particle flaw detector, thiab ultrasonic flaw detector kom ntseeg tau tias peb cov khoom.
