Them mloog mus rau ib puag ncig tus phooj ywg thiab kev nyab xeeb ntau dua yuav yog txoj kev loj hlob ntawm kev lag luam tsheb, uas yuav ua rau muaj kev loj hlob ntawm kev lag luam.txias dov tsheb ntawvnyob rau hauv cov kev taw qhia ntawm ultra-drawability, ultra-siab zog, txheej thiab tshwj xeeb.
Qhov tshwm sim ntawm interstitial-free steel (IF steel) tau ua rau kev lag luam tsim cov ntawv txias-dov tsheb nrog ultra-dav duab qhov kev ua tau zoo. Txo cov nqi tsim khoom ntawm IF steel thiab ntxiv kev txhim kho cov khoom qib tam sim no yog qhov tseem ceeb ntawm IF steel ntau lawm thiab kev tshawb fawb.
Nrog rau txoj kev loj hlob ntawm kev lag luam tsheb, cov qauv zoo ntawm cov ntawv txias-kuav los ntawm cov tsheb loj muaj zog tau txais ntau dua thiab siab dua. Thaum ua kom muaj kev ua tau zoo, cov khoom siv zog kuj yuav tsum tau txhim kho zoo heev los xyuas kom meej tias cov khoom muaj zog thiab formability zoo sib xws.
Coated steel daim hlau yog ntau yoog raws li cov kev xav tau ntawm kev txhim kho tsheb lub neej thiab kev tiv thaiv corrosion. Raws li cov txheej txheem kev ua tau zoo tsis tu ncua, tag nrho qhov zoo ntawm cov hlau phaj yog txhim kho ntxiv, thiab kev siv yuav nce sai.
Cov txheej txheem ntawm cov ntaub ntawv txias-kuav los tiag tsheb yog qhov nyuaj thiab nyuaj, thiab kev tsim khoom thiab kev ua haujlwm zoo ntawm txhua txoj kev txwv ib leeg. Nyob rau hauv xyoo tas los no, cov ntawv txias txias-kuav los tiag ntawm lub tsheb hauv tsev thiab txawv teb chaws tau maj mam tsim, tsim thiab txhim kho lub hauv paus ntsiab lus ntawm kev tsim khoom zoo ib yam, thiab sib koom ua ke ntawm ntau yam txheej txheem koom nrog hauv smelting, nruam casting, kub dov, txias dov, annealing thiab txheej. Kev npaj ntau lawm thiab kev tswj xyuas zoo muab cov txheej txheem thev naus laus zis thiab kev tswj hwm kev txhawb nqa rau kev tsim cov ntawv txias-kuav los tiag ntawm lub tsheb.
