Tsis tshua muaj kub resistant seamless steel yeeb nkab, raws li lub npe qhia, yog seamless steel yeeb nkab uas tseem muaj peev xwm tuav tau zoo heev nyob rau hauv qis kub tej yam kev mob. Nws feem ntau muaj qhov zoo ntawm qhov kub thiab txias toughness, qaug zog tsis kam thiab corrosion kuj, thiab tuaj yeem tswj kev ruaj ntseg ntawm lub zog thiab hardness ntawm qhov kub tsis tshua muaj siab kom ntseeg tau tias kev ua haujlwm zoo ntawm cov kav dej thiab cov khoom siv. Tsis tas li ntawd, qhov kub-resistant seamless steel yeeb nkab kuj muaj kev ua haujlwm zoo thiab kev ua haujlwm vuam, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm ntau yam txheej txheem nyuaj.
Cov txheej txheem ntau lawm
Cov txheej txheem tsim khoom ntawm qhov kub thiab txias resistant seamless steel yeeb nkab feem ntau suav nrog cov kauj ruam ntawm smelting, dov, txias ua hauj lwm, kev kho cua sov thiab kev soj ntsuam zoo. Nyob rau hauv cov txheej txheem smelting, smelting khoom xws li hluav taws xob rauv los yog converter yog siv los deoxidise, deslag thiab alloy cov hlau kom tau cov hlau ntshiab. Nyob rau hauv cov txheej txheem dov, cov kua hlau yog txhaj rau hauv lub tshuab rolling rau dov, maj mam txo cov yeeb nkab txoj kab uas hla thiab tau txais cov phab ntsa thickness uas yuav tsum tau, thaum lub npoo ntawm cov yeeb nkab steel yog kho nrog lub ci tiav. Kev kho mob ua haujlwm txias xws li kos duab txias lossis txias dov tuaj yeem txhim kho qhov tseeb thiab qhov zoo ntawm cov yeeb nkab steel. Kev kho cua sov tshem tawm cov kev ntxhov siab nyob hauv cov yeeb nkab thiab txhim kho nws cov kev ua tau zoo tag nrho los ntawm kev kub siab tempering. Thaum kawg, cov yeeb nkab steel tau raug soj ntsuam nruj, xws li eddy tam sim no tsis pom kev, kuaj hydraulic thiab X-ray tshuaj xyuas, los xyuas kom meej qhov zoo thiab kev ntseeg siab ntawm cov yeeb nkab steel.
