Txheej txheem ntau thiab cov yam ntxwv ntawm kev sib tsoo pob ntau lawm

Yuav ua kom haum rau cov kev xav tau ntawm lub lag luam thoob ntiaj teb, peb nquag ua kom paub cov tshiab technologies, ntxiv dag zog rau cov cuab yeej ua kom tiav, tsim cov haujlwm tshiab, los ntawm kev tsim cov khoom sib tsoo, tsim hluav taws xob rau cov khoom siv hluav taws xob, cov khoom siv thiab kev kho cua kub, los ntawm cov cuab yeej tswj, nws tuaj yeem tsim cov khoom kub zoo milled steel npas thiab lwm hom kev sib tsoo ntawm ntau yam kev sib zog thiab cov khoom sib fais fab raws li cov neeg yuav tsum tau ua.

Piv rau cov txheej txheem forging forging, lub ntsiab kom zoo dua cov pob zeb tawg uas ua los ntawm kev sib tsoo pob ntau lawm kab yog lub pob txha tsis nquag siv. Hauv cov txheej txheem kev sib tsoo ntawm cov khoom sib tsoo ntau lawm, cov khoom siv khib nyiab xws li cov hlau khawb thiab cov kav hlau khib nyiab yog cua sov ntawm cov hluav taws xob hluav taws xob kom tawg tag. Thaum lub sij hawm melting txheej txheem ntawm lub them nyiaj, precious hlau alloy yog ntxiv rau lub cub tawg rau tshuaj lom neeg muaj quenching thiab tempering. Tom qab qhov kub ncav siab tshaj 1550 ° C thiab ua tau raws li cov txheej txheem ntawm cov txheej txheem, tsim nyog hlau raug muab pov rau hauv qhov sib tsoo steel pob pwm los yog hlau pob ntau lawm kab tuaj pwm.

Qhov txoj kab nruab nrab ntawm kev sib tsoo pob ntsuas yog ntsuas los ntawm ib qho ntsuas ntsuas nrog qhov tseeb ntawm tsis pub tsawg tshaj li 0.1 hli. Qhov sib tw ntawm qhov taub ntawm pob zeb casting dua los ntawm qhov chaw ntawm lub qhov rooj thiab qhov chaw ntawm lub pob yuav tsum tsis pub tshaj 3HRC, thiab txoj kab uas hla ntawm lub pob zeb sib tsoo pob zeb yuav tsum ntsuas los ntsuas ntawm qhov ntsuas tsis tsawg dua li 0.1 hli. Yog hais tias qhov nyuaj ntawm lub siab chromium pob (HRC) yog tsawg dua 54 los ntawm kev siv Rockwell hardness tester, lub siab chromium pob tsis raug ntxig rau kev kho cua sov ntawm tag nrho los yog lub hardness tsis quenched.
