Lus piav qhia luv luv:

Kub dov kauj yog hais txog kev nias ntawm billets rau hauv qhov xav tau tuab ntawm cov hlau ntawm qhov kub thiab txias. Nyob rau hauv kub dov, hlau yog dov tom qab tau rhuab mus rau ib lub xeev yas, thiab nto yuav oxidized thiab ntxhib. Kub dov coils feem ntau muaj qhov loj me me thiab tsis muaj zog thiab tawv, thiab tsim nyog rau kev tsim kho, cov khoom siv kho tshuab hauv kev tsim khoom, cov kav dej thiab cov ntim khoom.

Txheej txheem ntau lawm

Cov txheej txheem ntau lawm ntawm kub dov steel kauj yog qhov txuas tseem ceeb hauv kev tsim steel. Nws tsuas yog tsim cov hlau billet rau hauv lub phaj uas xav tau los ntawm kev kub kub dov. Cov hauv qab no yog nws cov kauj ruam tseem ceeb:
Kev npaj raw khoom
Siv nruam casting billet los yog pib dov billet li raw khoom, thiab cov billet thickness feem ntau yog 150-300mm.
Lub billet yog nto huv si (xws li nplaim taws tu los yog txhua yam sib tsoo) kom tshem tawm oxide nplai thiab tsis xws luag los xyuas kom meej dov zoo.
Cua sov
Lub tshuab hluav taws xob xa mus rau lub tshuab hluav taws xob kauj ruam-kab cua sov thiab ua kom sov rau 1100-1300 ℃ kom lub pob zeb ncav cuag qhov kub thiab txias thiab txhim kho cov yas.
Tswj lub sijhawm cua sov thiab qhov kub tsis sib xws kom tsis txhob overburning lossis kub tsis txaus.
Rough Rolling
Lub pob zeb tuab yog txo mus rau 30-50mm los ntawm kev thim rov qab ntxhib dov zeb (xws li ob-yob lossis plaub-yob zeb) los ua ib qho nruab nrab ntawm cov pob zeb.
Kev kub siab dej descaling tuaj yeem ua tau tom qab txhua qhov dov dhau los tshem tawm cov txheej oxide saum npoo.
Ua tiav Rolling
Qhov nruab nrab billet nkag mus rau hauv lub zeb tiav (feem ntau yog 6-7 plaub-yob lossis rau-yob mills), thiab maj mam thinned mus rau lub hom phiaj thickness (xws li 1.2-25mm) los ntawm kev nruam dov.
AGC (automatic thickness tswj) thiab phaj zoo tswj qhov system yog siv los xyuas kom meej qhov tseeb qhov tseeb thiab phaj duab ncaj.
Cov rollers yuav tsum tau txias thiab lubricated thaum dov los tiv thaiv thermal deformation thiab hnav.
Txias
Lub tshuab ua kom txias laminar yog siv los ua kom txias txias ntawm steel sawb los ntawm qhov kawg dov kub (kwv yees li 800 ℃) mus rau chav tsev kub los ntawm kev tswj cov dej ntim thiab txias npaum li cas (xws li 30-50 ℃ / s).
Cov txheej txheem cua txias ncaj qha cuam tshuam rau microstructure (xws li ferrite thiab pearlite piv) thiab txhua yam khoom ntawm cov hlau kauj.
Coiling
Cov hlau sawb yog dov mus rau hauv ib lub kauj hlau los ntawm lub pinch roller thiab coiler, thiab qhov nro yog tswj ntawm 100-500N / mm² kom ntseeg tau tias lub kauj zoo yog nruj thiab tsis muaj xoob coil.
Lub coiling kub feem ntau yog tswj ntawm 550-700 ℃ kom ua tau zoo.
Kev kho mob tom ntej
Kev kho saum npoo: pickling kom tshem tawm oxide nplai, los yog galvanizing, aluminium plating thiab lwm yam txheej txheej.
Annealing: txhim kho cov khoom ductility (xws li recrystallization annealing ua ntej txias dov).
Smoothing: tshem tawm cov yield platform thiab txhim kho nto tiav los ntawm kev txo tus nqi me me dov.
Kev soj ntsuam zoo thiab ntim khoom: xyuas qhov loj me, txhua yam khoom thiab qhov chaw zoo, thiab yob, ntim thiab cim raws li cov neeg siv khoom xav tau.
