Dab tsi yog qhov txawv ntawm kub dov square steel thiab txias dov square steel?
Ua ntej ntawm tag nrho cov, kub-kuav los tiag square steel yog tau los ntawm dov lub steel billet ntawm kub kub. Nyob rau hauv cov txheej txheem kub dov, tom qab lub steel billet yog rhuab mus rau ib tug ntau dua kub, nws yog tsis tu ncua dov mus tas li hloov tus ntoo khaub lig-sectional duab ntawm cov hlau kom tau lub thickness ntawm cov square steel.
Nyob rau hauv sib piv, txias-dov square steel yog ntxiv ua thiab kho nyob rau hauv chav tsev kub. Nyob rau hauv cov txheej txheem txias dov, cov kub-kuav los tiag square steel yog thawj annealed kom txo tau lub hardness, thiab ces dov los ntawm ib tug txias dov zeb ua rau cov hlau nto smoother thiab zoo li qub.
Nyob rau hauv cov nqe lus ntawm lub cev khoom, kub dov square steel muaj ntau dua plasticity thiab toughness. Vim yog dov ntawm qhov kub thiab txias, cov nplej sab hauv ntawm kub dov square steel yog loj dua thiab cov qauv yog looser, yog li nws muaj plasticity zoo dua thiab tsim nyog rau kev ua ntau yam duab. Cold-rolled square steel muaj ntau dua hardness thiab lub zog. Nyob rau hauv cov txheej txheem txias dov, lub tshuab txias ua haujlwm tuaj yeem ua rau cov hlau nplej zoo thiab cov microstructure zoo ib yam thiab ntom, yog li txhim kho lub zog thiab hardness ntawm cov hlau.
Tsis tas li ntawd, muaj qhov sib txawv ntawm qhov zoo thiab cov tsos ntawm kub dov square steel thiab txias-dov square steel. Muaj qee qhov nplai thiab xeb ntawm qhov kub-kuav los tiag square steel, thiab cov tsos zoo li ntxhib, thiab tom qab kho nto (xws li pickling, polishing, thiab lwm yam) yuav tsum tau tshem tawm cov tsis xws luag. Txawm li cas los xij, txias-kuav los tiag square steel muaj ib tug smoother nto, tsis muaj nplai thiab xeb, thiab muaj ib tug zoo tsos zoo tom qab ua tiav los ntawm ib tug txias dov zeb, thiab tuaj yeem siv ncaj qha rau kev tsim thiab siv.
Kuj tseem muaj qee qhov sib txawv ntawm cov khoom tshwj xeeb thiab cov teb siv tau ntawm cov kub dov square steel thiab txias-dov square steel. Kub dov square steel ntau lawm kab feem ntau muaj peev xwm ntau lawm thiab tuaj yeem tsim cov square steels ntawm ntau yam specifications, uas yog dav siv nyob rau hauv kev tsim kho, machinery manufacturing, shipbuilding thiab lwm yam teb. Cold-rolled square steel ntau lawm kab feem ntau tsim me me specifications ntawm cov khoom, nrog rau ntau lub kaum sab xis steels, ca steels, thiab lwm yam, uas yog tsuas yog siv nyob rau hauv lub tsev kho kom zoo nkauj, automotive qhov chaw thiab lwm yam teb.
