Txias dov yog hais txog txoj kev dov ntawm kev hloov cov duab ntawm cov hlau los ntawm extruding steel nyob rau hauv lub siab ntawm yob ntawm chav tsev kub. Txawm hais tias cov txheej txheem kuj heats li steel ntawv, nws tseem hu ua txias dov. Tshwj xeeb, qhov kub-dov steel coil rau txias dov yog siv los ua cov khoom siv raw, thiab cov nplai oxide raug tshem tawm los ntawm kev khaws cia, thiab tom qab ntawd kev ua haujlwm siab yog ua tiav, thiab cov khoom tiav yog ib qho nyuaj dov.
Feem ntau, txias-dov hlau xws li galvanized steel thiab xim hlau phaj yuav tsum tau annealed, yog li cov yas thiab elongation kuj zoo, thiab nws yog dav siv hauv tsheb, khoom siv hauv tsev, kho vajtse thiab lwm yam lag luam. Qhov saum npoo ntawm daim ntawv txias-kuav los tiag muaj qee qhov kev sib tw, thiab txhais tes zoo li smoother, feem ntau yog los ntawm pickling. Qhov saum npoo ntawm cov ntawv kub dov feem ntau tsis ua raws li qhov yuav tsum tau ua, yog li cov hlau kub-kuav los tiag yuav tsum tau txias-dov. Lub thinnest kub-dov steel sawb feem ntau yog 1.0mm, thiab cov kab hlau txias txias tuaj yeem ncav cuag 0.1mm. Kub dov yog dov saum lub crystallization kub taw tes, thiab txias dov yog dov hauv qab ntawm crystallization kub taw tes.
Kev hloov pauv ntawm cov duab ntawm cov hlau los ntawm txias dov belongs rau qhov txias txias deformation. Qhov txias ua hauj lwm hardening tshwm sim los ntawm cov txheej txheem no tsub kom lub zog, hardness thiab toughness thiab yas Performance index ntawm dov hard coil.
Rau kev siv kawg, txias dov deteriorates stamping zog, thiab cov khoom yog haum rau yooj yim deformation qhov chaw.
Product Advantage:
Nws tuaj yeem rhuav tshem cov qauv casting ntawm lub ingot, kho cov nplej ntawm cov hlau, thiab tshem tawm qhov tsis xws ntawm microstructure, kom cov qauv hlau yog ntom thiab cov khoom siv kho kom zoo tuaj. Qhov kev txhim kho no feem ntau yog tshwm sim hauv cov kev taw qhia dov, kom cov hlau tsis yog lub cev isotropic rau qee yam; cov npuas, tawg thiab porosity tsim thaum lub sij hawm casting kuj yuav welded nyob rau hauv qhov kev txiav txim ntawm kub thiab siab.
Qhov shortcoming:
1. Tom qab kub dov, cov non-metallic inclusions (tsuas yog sulfides thiab oxides, nrog rau silicates) nyob rau hauv cov hlau yog nias rau hauv nyias nyias, thiab delamination tshwm sim. Delamination zoo heev deteriorates lub tensile zog ntawm cov hlau los ntawm lub thickness, thiab muaj peev xwm rau interlaminar tearing raws li cov weld shrinks. Lub hauv paus strain induced los ntawm shrinkage ntawm weld feem ntau ncav cuag ob peb lub sij hawm lub yield point strain, uas yog ntau npaum li cas loj tshaj lub strain tshwm sim los ntawm lub load;
2. Kev ntxhov siab uas tshwm sim los ntawm qhov tsis sib xws. Residual stress yog qhov kev ntxhov siab ntawm tus kheej-theem equilibrium uas tsis muaj kev quab yuam sab nraud. Kub dov seem steel ntawm ntau seem muaj xws li residual stress. Feem ntau, qhov loj dua qhov loj ntawm cov seem steel, qhov loj dua qhov seem seem. Txawm hais tias qhov seem ntawm kev ntxhov siab yog qhov sib npaug ntawm tus kheej, nws tseem muaj qee yam cuam tshuam rau kev ua haujlwm ntawm cov tswv cuab steel nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam. Piv txwv li, nws yuav muaj kev cuam tshuam tsis zoo rau deformation, stability, thiab qaug zog ua hauj.
