Kub dov hlauthiabtxias dov steelyog ob hom hlau siv rau ntau lub hom phiaj hauv kev lag luam sib txawv.
Ob leeg kub dov carbon steel thiab txias dov carbon steel yog ua tiav ntawm qhov kub sib txawv los muab lawv cov khoom tshwj xeeb. Kub dov hlau yog tsim nyob rau ntawm qhov kub siab tshaj qhov recrystallization point ntawm cov hlau, feem ntau nyob ib ncig ntawm 1700 ° F, thaum txias dov hlau yog ua nyob rau hauv chav tsev kub. Cov txheej txheem sib txawv no muab txhua hom hlau tshwj xeeb thiab cov tsos.
Txoj kev yooj yim tshaj plaws los sib txawv ntawm cov kub dov steel thiab txias dov hlau yog nyob rau hauv qhov chaw tiav. Vim yog qhov tsim ntawm oxide nplai thaum lub sij hawm txias, qhov oxide nplai muab kub dov hlau nws tus yam ntxwv xim dub los yog grey thiab ntxhib ntxhib ntxhib ntxhib los mos. Tsis muaj oxide scale ntawm txias dov hlau, yog li nws muaj ib tug smoother nto tiav thiab ib tug huv si, kaj tsos.
Lwm qhov sib txawv ntawm qhovkub dov low carbon steelthiabtxias dov qis carbon steelyog lawv dimensional tolerances thiab mechanical zog. Kub dov hlau nyhav yuav tsis tshua muaj qhov loj me thiab tsis sib xws hauv cov tuab thiab cov duab. Cold dov steel yog ua tiav kom nruj dua qhov ntev, yog li cov tuab thiab cov duab zoo ib yam.
Tsis tas li ntawd, qhov tensile thiab yield zog ntawm txias-kuav los tiag steel feem ntau siab dua cov kub-kuav los tiag steel, ua rau nws tsim nyog rau daim ntaub ntawv uas yuav tsum tau ib tug muaj zog thiab meej cov khoom. Hauv kev tsim, kub-kuav los tiag steel feem ntau yog siv rau loj, tuab steel khoom xws li rails, I-beams, thiab structural Cheebtsam, thaum txias-kuav los tiag steel feem ntau yog siv rau me me, complex khoom xws li automotive qhov chaw, khoom, thiab hlau rooj tog.
