Kev tsim cov kauj kub dov pib nrogkev npaj cov khoom siv raw, qhov twg cov hlau slabs zoo raug xaiv raws li cov tshuaj lom neeg thiab cov qauv xav tau.
Cov slabs ces raug cua sov rau hauv ib qholub cub tawg rov ua kom sovrau qhov kub siab tshaj qhov recrystallization point, kom ntseeg tau tias muaj plasticity zoo rau dov.
Tom ntej no, cov slabs uas tau raug cua sov raug hloov musdov ntxhib, qhov twg cov tuab maj mam txo qis los ntawm ntau zaus hla mus rau tsim cov hlau nruab nrab.
Tom qab roughing, lub strip nkag mus rau hauvcov chaw ua tiav dov, qhov twg kev tswj qhov tuab, qhov dav raug, thiab cov khoom siv kho tshuab tau ua tiav.
Tom qab ntawd, daim kab xev kub kub raug raulaminar flow txias, uas tswj qhov ceev txias kom zoo dua qub thiab txhim kho lub zog thiab kev tawv.
Thaum kawg, lub steel strip yogcoiled thiab ntim khoom, tsim cov kauj kub dov npaj rau kev khaws cia, kev thauj mus los, thiab kev ua tiav ntxiv xws li txiav, vuam, lossis tsim khoom.
Cov Txheej Txheem Ntim Rau Cov Hlau Kub Rolled
Kev Thauj Mus Los:Qhia (Xa Khoom Qauv), Huab Cua, Tsheb Ciav Hlau, Av, Tsheb Ciav Hlau, Kev Thauj Khoom Hiav Txwv (FCL lossis LCL lossis Ntau)
Q1: Cov khoom siv kub dov siv rau dab tsi?
Kev tsim cov hlau kub dov yog siv los tsim cov ntawv hlau thiab cov kauj rau kev tsim kho, kev tsim kho vaj tse, cov khoom siv tsheb, cov kav dej, thiab cov ntawv thov kev lag luam dav dav.
Q2: Vim li cas hlau thiaj raug cua sov ua ntej dov?
Kev ua kom cov hlau slab sov dua ua rau nws yooj yim dua los hloov pauv, txo qhov tsis kam hloov pauv, thiab ua rau nws yooj yim dua los hloov thaum lub sijhawm dov.
Q3: Lub hom phiaj ntawm kev dov ntxhib thiab kev dov tiav yog dab tsi?
Kev dov tsis ncaj yuav txo qhov tuab ntawm lub slab, thaum kev dov tiav ua kom muaj qhov loj me meej, zoo dua qhov zoo ntawm qhov chaw, thiab ruaj khov kho.
Q4: Laminar flow cooling siv rau dab tsi?
Kev txias laminar tswj qhov txias ntawm cov hlau, ua kom nws cov qauv me me zoo dua los txhim kho lub zog, kev tawv, thiab kev ua haujlwm zoo ib yam.
Q5: Cov txheej txheem no cuam tshuam li cas rau qhov zoo ntawm cov hlau?
Cov txheej txheem dov thiab txias uas tswj tau ua rau cov khoom siv kho tshuab zoo dua, ua kom muaj qhov tuab sib npaug, muaj zog, thiab ua tau zoo.
