Lub phaj steel yog ib lub tiaj tus hlau uas yog cam khwb cia nrog molten steel thiab nias tom qab txias.
Cov ntawv hlau yog tiaj tus, duab plaub thiab tuaj yeem ncaj qha dov los yog txiav los ntawm cov hlau dav dav.
Cov hlau phaj yog muab faib raws li thickness, nyias steel phaj yog tsawg tshaj li 4 hli (thinnest yog 0.2 hli), nruab nrab-thick steel phaj yog 4-60 hli, thiab lub thickness ntawm steel phaj yog 60-115. mm.
Cov ntawv hlau tau muab faib ua phaj kub dov thiab txias dov phaj raws li dov.
1. Kub Rolled Steel Phaj
Kub dov txheej txheem muaj xws li kub dov, forging, extrusion thiab lwm txoj kev.
2. Txias Rolled Steel Phaj
Cov txheej txheem txias dov muaj xws li txias dov, kos duab txias thiab kos duab txias, txias khoov, txias extrusion thiab lwm txoj kev.
Txoj kev txias dov yog txuas ntxiv ua cov kub dov hlau hauv qab qhov kub ntawm recrystallization kom nws txias dov hlau.Siv cov txheej txheem txias dov tuaj yeem txhim kho cov khoom siv ntawm cov hlau, thiab tau txais cov khoom lag luam nrog qhov tseeb qhov tseeb thiab qee qhov smoothness.
