Txias dov yog ua tiav thiab dov los ntawm kub dov coils. Feem ntau hais lus, nws yog txheej txheem kub dov ---pickling---txias dov. Cov ntawv kub dov muaj qhov hardness tsawg, ua haujlwm yooj yim thiab zoo ductility. Cov ntawv txias-kuav los tiag muaj siab hardness thiab kuj nyuaj rau txheej txheem, tab sis nws tsis yooj yim rau deform thiab muaj lub zog siab. Lub zog ntawm cov phaj kub dov yog qhov tsawg, thiab qhov zoo ntawm qhov chaw tsis zoo (oxidation tsis tiav), tab sis cov yas yog zoo, feem ntau nruab nrab thiab tuab daim hlau, txias-kuav los tiag daim hlau: siab zog / siab hardness, siab nto. tag, feem ntau nyias daim hlau, tuaj yeem siv los ua stamping Siv lub rooj tsavxwm.
Cov khoom siv hluav taws xob ntawm cov ntawv kub dov steel yog qhov qis dua rau kev ua haujlwm txias, thiab tseem qis dua rau kev ua haujlwm forging, tab sis lawv muaj qhov zoo dua toughness thiab ductility.
Txias-rolled steel phaj muaj qee qhov kev ua haujlwm hardening thiab tsis tshua muaj zog, tab sis nws tuaj yeem ncav cuag cov txiaj ntsig zoo dua. Nws yog siv rau txias-bending caij nplooj ntoos hlav nplooj ntawv thiab lwm yam. Nyob rau tib lub sijhawm, vim tias qhov taw tes tawm los ze dua rau lub zog tensile, tsis muaj kev phom sij thaum siv. Foreseeability, kev huam yuaj yog nquag tshwm sim thaum lub load tshaj qhov tso cai load.
