Cov ncauj lus kom ntxaws txog kev tsim khoom ntawm 42CrV6 Steel

Cov txheej txheem tsim khoom ntawm 42CrV6 steel feem ntau suav nrog cov kauj ruam hauv qab no:

Kev npaj raw khoom: Xaiv cov ntaub ntawv tsim nyog xws li ferroalloys thiab seem hlau, thiab xyuas kom meej tias lawv cov khoom sib xyaw thiab cov khoom ua tau raws li qhov yuav tsum tau ua. Ua kev tshuaj xyuas thiab ua ntej ntawm cov khoom siv raw, suav nrog kev tu, crushing, thiab batching.

Melting: Ntxiv cov khoom nyoos npaj rau hauv lub qhov cub kom yaj. Cov furnaces muaj xws li hluav taws xob arc rauv thiab induction furnaces. Thaum lub sij hawm melting txheej txheem, cov ntaub ntawv raw yog melted los ntawm high-temperature cua sov thiab tshuaj lom neeg cov tshuaj tiv thaiv tshwm sim kom ua tiav cov tshuaj muaj pes tsawg leeg thiab kub.

Kev kho kom zoo: Ua kom cov hlau molten tom qab melting kom tshem tawm impurities thiab gases thiab txhim kho cov purity ntawm cov hlau. Refining txoj kev muaj xws li ladle furnace refining (xws li LF rauv, VD rauv, thiab lwm yam), argon stirring, thiab alloying.

Casting: Muab cov hlau ua kom zoo zoo rau hauv cov pwm rau casting kom tau txais ingots lossis nruam casting billets. Casting txoj kev muaj xws li ingot casting thiab nruam casting. Nruam casting muaj qhov zoo ntawm kev ua haujlwm siab, tus nqi qis, thiab ruaj khov zoo, thiab tau siv dav hauv kev tsim cov hlau niaj hnub.

Rolling: Yob cov ingots los yog nruam casting billets kom deform lawv mus rau hauv qhov xav tau cov duab thiab qhov ntau thiab tsawg, xws li steel phaj, steel kav, thiab tuav. Cov txheej txheem dov muaj xws li ntxhib dov, nruab nrab dov, thiab ua tiav dov. Los ntawm cov txheej txheem dov sib txawv thiab kev tswj xyuas qhov ntsuas, cov khoom siv steel nrog kev ua haujlwm zoo thiab qhov zoo ntawm qhov chaw tuaj yeem tau txais.

Kev kho cua sov: Raws li cov khoom yuav tsum tau ua, ua kev kho cua sov ntawm cov hlau dov, xws li quenching, tempering, normalizing, thiab lwm yam. Kev kho cua sov tuaj yeem txhim kho cov microstructure thiab cov khoom ntawm cov hlau thiab ua rau nws lub zog, hardness, toughness, thiab lwm yam.

Kev kho saum npoo: Txhawm rau txhim kho corrosion kuj, hnav tsis kam, thiab qhov zoo ntawm cov hlau, kev kho deg yuav tsum tau, xws li galvanizing, aluminizing, painting, thiab lwm yam.

Kev soj ntsuam zoo: Ua kev soj ntsuam zoo ntawm cov hlau nyob rau ntau theem ntawm cov txheej txheem tsim khoom, suav nrog tshuaj lom neeg kev tshuaj ntsuam xyuas, ntsuas cov cuab yeej cuab tam, kev soj ntsuam cov qauv metallographic, thiab ntsuas qhov ntev. Tsuas yog cov khoom siv hlau uas dhau qhov kev soj ntsuam zoo tuaj yeem muag.

Ntawm no yog ib daim ntawv qhia txog cov ntaub ntawv tseem ceeb ntawm 42CrV6 steel manufacturing txheej txheem:
