Kev tsim khoom lag luam
Ua haujlwm siab
Tsis muaj kev nyuaj siab me ntsis
Kub dov yog cov cuab yeej zoo tshaj plaws rau kev tsim khoom loj ntawm cov khoom siv steel ntev par zoo heev vim nws feem ntau pheej yig dua li cov hlau txias. Tsis tas li ntawd, nws tso cai rau cov khoom siv ua tiav thiab tsim tau yooj yim. Lwm qhov txiaj ntsig tseem ceeb yog, qhov kub dov steel yog xyaum tsis pub muaj kev ntxhov siab sab hauv, vim tias cov hlau tau txias zuj zus. Txawm li cas los xij, kev pom zoo yuav tsum tau ua raws li qhov tseeb ntawm qhov profile thiab qhov kawg ntawm qhov kub-dov profiles.
Cold-rolled steel yog dab tsi?
Nyob rau hauv sib piv rau kub dov, nyob rau hauv txias dov, cov khoom dov feem ntau yog tsim nyob rau hauv chav tsev kub thiab yog li hauv qab no lub recrystallization kub. Thaum txias dov profiles, ib tug hlau pas nrig yog siv raws li ib tug semi-tiav khoom. Qhov xav tau profile cross-section ntawm cov khoom kawg kuj txiav txim siab lub cheeb ntawm cov hlau. Cov txheej txheem feem ntau yog siv los ua cov khoom siv dav dav xws li cov ntawv hlau.
Rau qhov tshwj xeeb ntawm qhov profile hla ntu, ntau cov txheej txheem dov yuav tsim nyog. Qhov no ua rau cov profiles yuav tsum tau daws annealed ua ntej dhau cov hauv qab no. Lub hom phiaj tseem ceeb ntawm kev txias dov yog txo cov thickness ntawm cov ntawv hlau. Cov khoom uas yuav tsum tau dov feem ntau twb dhau los kub dov.
Qhov zoo ntawm txias-kuav los tiag steel
Siab raug
Nce hardness
Ua kom muaj zog
Zoo heev nto finish
Txias dov tuaj yeem siv los tsim cov kev ua siab ntev heev. Nws yog li ntawd ib txoj kev tsim khoom zoo tshaj plaws rau kev tsim khoom me me rau nruab nrab qhov tshwj xeeb profiles. Raws li cov hlau yog zoo li tus nyob rau hauv qis kub, txias-kuav los tiag steel muaj ib tug ntxiv hardness txog li 20% nrog rau kev txhim kho cov qoob loo thiab tensile zog. Tsis tas li ntawd, qhov chaw ua los ntawm txias-kuav los tiag steel muaj ib tug heev du nto, tsis muaj xeb thiab nplai.
