Kub- dov nyias daim ntawv (lub sij hawm txawv teb chaws: * latten *) yog cov khoom siv metallurgical nrog lub thickness ntawm 1.2 mus rau 6 hli. Nws yog feem ntau ua tiav thiab tsim siv tas li kub- dov mills, nyias-slab nruam casting thiab dov kab, los yog ESP (Endless Strip Production) kab; nws tseem tuaj yeem tau txais kev kho mob pickling thiab annealing los ua cov coiled kub- dov nyias strips. Cov khoom tau muab faib ua ob hom: "raws li-rolled coils" thiab "finished coils." Cov ntaub ntawv qib suav nrog carbon structural steel, qis- alloy steel, alloy structural steel, thiab lwm yam, ua raws li tus qauv GB/T 912. Nws cov khoom siv kho tshuab raug suav nrog lub zog tensile ntawm Ntau dua lossis sib npaug ntawm 310 MPa thiab elongation ntawm Ntau dua lossis sib npaug li 38%; tshwj xeeb, cov hlau tsim los ntawm Ansteel rau cov neeg caij tsheb npav ua haujlwm nta ib qho kev sib hloov elongation ntawm Ntau dua lossis sib npaug li 28% thiab ua tiav dhau 180℃transverse txias dabtsi yog khoov kuaj.
Cov khoom siv no tau siv dav hauv ntau qhov chaw, suav nrog cov tshuab, tsheb, kev tsim kho, thiab lub zog. Tshwj xeeb, nws yog ua haujlwm nyob rau hauv kev tsim cov tshuab casings, tsheb springs, photovoltaic mounting brackets, corrosion-cov hlab ntsha, thiab cov khoom zoo sib xws. Los ntawm nyias-slab nruam nruam casting thiab dov tshuab, nws muaj peev xwm tsim tau ultra- nyias ntsuas mus txog 0.8 hli, nrog cov txheej txheem pickling thiab annealing siv los ntxiv txhim kho qhov zoo. Muab piv rau cov ntawv txias- dov nyias, cov khoom no yog cov yam ntxwv ntawm qhov muaj cov nplais; Tsis tas li ntawd, leveraging ESP thev naus laus zis ua kom tiav cov txheej txheem ntau lawm-los ntawm cov hlau molten mus rau 0.7 mm tiav coil- kom ua tiav hauv tsuas yog xya feeb.
