Txias Rolling Zeb: Ib qho precision yav dhau los hauv kev lag luam niaj hnub

Raws li cov khoom siv tseem ceeb hauv kev ua haujlwm hlau, kev tswj lub xov tooj ntawm lub xov tooj hlau tsis zoo tshaj plaws hauv phab ntsa, peb tuaj yeem tshawb pom cov khoom lag luam me me cov txheej txheem txias-dov .
Kuv {. lub cev lub cev ntawm cov txheej txheem txias txias
The cold rolling process conducts plastic deformation below the recrystallization temperature of the metal. The metal grains elongate along the rolling direction to form a fibrous structure, and the sharp increase in dislocation density brings about a significant work hardening effect. The reconstruction of this microstructure enables the material's yield strength to increase by 30%-50%, and the Rockwell Hardness HRB tus nqi feem ntau nce los ntawm10-20}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} {}}
Thaum lub sij hawm yob cov txheej txheem, peb-seem kev ntxhov siab ua rau muaj kev sib txawv ntawm cov khoom siv sib txhuam thiab cov kev sib txawv ntawm cov khoom sib txawv Dov system nyob rau hauv lub sijhawm tiag tiag los ntawm cov khoom lag luam yob tawm, uas tuaj yeem tswj cov hlau txuas ntawm lub ntsej muag ntawm 0.3mm ntawm cov khoom lag luam ntawm cov khoom siv tshwj xeeb.
II {{.} iterative evolution ntawm cov khoom siv
Tus tsim qauv ntawm Intermediate Support yob nyob rau hauv lub rau-siab Rolling Mill qauv, los yog tseem muaj kev them nyiaj ntau dua li ntawm cov khoom siv ± 0 {{.} 00 00 001mm thaum dov 0 . 05mm stainless hlau ntawv nyiaj. Hauv 2022, qee yam kev lag luam Japanese tsim cov pob Tungsten carbide yob tau txhawb nqa nrog cov npoo av ntawm 10nm.
Cov kab sib txuas tas los ntawm kev ua haujlwm rollersible rolling {} Lub ntsej muag sib xyaw ua ke ntawm lub limtiam no tuaj yeem ua tiav kev hloov pauv hloov ntawm lub zog ntawm 50ms, kom ntseeg tau tias qhov tuab fickness hloov nyob rau hauv high-ceev rolling tsis pub tshaj 1 . 5% ntawm cov nqi teeb.
III {. Technical tawg rau lub neej yav tom ntej
Digital ntxaib thev naus laus zis tswj cov txheej txheem sib txawv los ntawm kev sib txuas lus ntawm lub cev, nce qib kev sib tw ua ntej ntawm 70% thiab ua kom luv dua cov khoom tsim kho ntawm 40% {{. Nyob rau hauv 2023, yssenkrupic, txo kev siv hluav taws xob ib tev ntawm steel los ntawm 15% .
Cov khoom siv hluav taws xob uas muaj zog ntxiv rau cov khoom siv hluav taws xob kom ua tiav. Cov txheej txheem annealing ib txwm ua thaum nce cov khoom elongation los ntawm 20% {8} prickological sib xyaw ntawm cov txias thiab kub dov thiab kub hauv lub sijhawm tshiab ntawm kev tsim cov hlau.
Nyob rau hauv nthwv dej 4 {{. 0, txias rolling rabtion {{{{} Tus phoj ib puag ncig lub neej 30% lub zog tus kheej txoj kev tiv thaiv. cov kev lag luam hluav taws xob tsis yog siv cov khoom siv txias thiab cov khoom siv hluav taws xob ntau dua, tab sis kuj siv cov lus qhia tshiab
