Dav Hlau Sawb Txhim Kho Nto Zoo Thiab Thickness raug

Thawj tiam ntawm kub strip rolling mill Qhov ntxov tshaj plaws kub strip rolling zeb tau muab tso rau hauv kev ua haujlwm hauv Tebchaws Meskas hauv xyoo 1926. Lub tshuab plaub-siab yog siv los ua kom nruj thiab tsim cov khoom dav thiab nyias. Lub cev muaj zog ntawm lub tshuab tiav yog DC lub cev muaj zog, uas yog siv los ntawm lub tshuab hluav taws xob. Lub slab siv nyob rau hauv tiam no ntawm dov mills yog 150-200 hli tuab, 1200-1550 hli dav thiab 2.5-5m ntev. Lub thickness ntawm dov Tshuag los ntawm lub roughing zeb yog feem ntau 20 mus rau 30 hli, thiab lub siab tshaj plaws ceev ntawm lub finishing zeb yog 8 mus rau 10 meters ib ob. Qhov siab tshaj plaws coil hnyav yog tsawg dua 10 tons, thiab lub coil hnyav ib chav tsev dav yog li 8kg / mm. Lub peev xwm tsim tau txhua xyoo yog li 600,{14}} txog 2,{16}},{17}} tons. Lub 1700mm ib nrab txuas ntxiv dov zeb muab tso rau hauv kev ua haujlwm los ntawm Tuam Tshoj Anshan Hlau thiab Hlau Tuam Txhab hauv xyoo 1959 yog hom no.

Qhov thib ob tiam kub sawb kub dov zeb tau muab tso rau hauv kev ua haujlwm hauv Tebchaws Meskas hauv xyoo 1961, thiab yog tus cwj pwm los ntawm kev siv cov txheej txheem nrawm nrawm ntawm dov zeb. Thaum lub sawb tawm ntawm lub tshuab tiav thiab lub hauv ntej kawg yog pub rau hauv lub coiler, lub tshuab tiav, lub rooj rau cov menyuam thiab cov coiler tau nrawm rau tib lub sijhawm, kom qhov ceev ntawm lub tshuab tiav yog nce mus rau 15-20 m ib ob, thiab lub kauj qhov hnyav ntawm ib chav tsev dav yog 18-20kg / mm, qhov hnyav yob yog 30 tons, thiab muaj peev xwm tsim tau txhua xyoo yog 4 lab tons. Tsis siv neeg thickness tswj, thickness thiab dav ntsuas ntsuas, zoo meej descaling thiab sawb cua txias tswj system, zoo ceev tswj system thiab micro nro looper ntaus ntawv yog saws nyob rau hauv no hom ntawm dov zeb. Nyob rau tib lub sijhawm, qhov kev nruj ntawm lub tshuab dov thiab lub zog ntawm lub ntsiab lub cev muaj zog tau nce ntxiv, kev hloov pauv ceev ceev tau ntxiv, thiab lub khoos phis tawj tswj hwm tau raug coj los txhim kho qhov zoo ntawm qhov chaw thiab tuab qhov tseeb.

Qhov thib peb-tiam dav band kub nruam dov zeb Nrog rau kev loj hlob thiab daim ntawv thov ntawm lub thib ob-tiam dov zeb tshuab, ua ke nrog kev loj hlob ntawm nruam casting tshuab thiab taug kev rauv, lub thib peb-tiam rolling zeb yog tsim los ntawm 197{{17} } mus txog rau xyoo 1978. Lub cub tawg nrog lub tshuab dov hom no tuaj yeem ua kom sov slabs hnyav txog li 45 tons thiab ntev txog li 15 meters. Nws tseem tuaj yeem txo cov cim dub uas ua rau lub sijhawm cua sov thiab txo qhov khawb ntawm qhov chaw ntawm lub slab. Lub peev xwm cua sov ntawm txhua qhov cub yog 300 tons. Lub coil hnyav ib chav tsev dav yog 36kg / hli, thiab qhov siab tshaj plaws dov ceev yog 28.5m ib ob. Lub peev xwm tsim tau txhua xyoo yog 6 lab tons. Qhov thib peb tiam dov zeb muaj cov yam ntxwv hauv qab no: ① Txo qhov ntev ntawm lub roughing zeb, txuag cov cuab yeej thiab cog kev nqis peev, thiab feem ntau siv 3/4 nruam dov mills. Lub tsheb ciav hlau tiav zeb muaj 7 qhov chaw, thiab lub thickness ntawm cov khoom dov nkag mus rau lub tsheb ciav hlau tiav yog 30-50 hli. ② Qhov luaj li cas ntawm cov khoom dov yog nyob ntawm 0.8 mus rau 25 hli, tab sis lawv cov kev lag luam rationality tseem yuav tsum tau txiav txim siab los ntawm tag nrho cov kev xav. ③Siv cov khoom siv hydraulic bending los tswj cov duab ntawm lub phaj thiab siv cov laminar ntws txias ntawm cov sawb los txhim kho cov hlau phaj zoo. Thiab sim rau nruab cov duab ntes kaw-voj tswj cov duab. ④ Cov txheej txheem tsim khoom ntawm tag nrho cov rhiav (los ntawm slab warehouse rau cov khoom tiav warehouse) yog tswj thiab tswj los ntawm lub computer. ⑤ Kev ua tiav tau ua tiav hauv kev txo qis kev siv hluav taws xob, txhim kho kev ua haujlwm, txhim kho cov khoom zoo, thiab txhim kho cov txiaj ntsig zoo, xws li qhov dav siab ntev ntawm cov sawb hlau ncav cuag ± 1 hli, lub thickness kam rau siab ncav cuag 0.05mm, tus nqi tsis kam lees yog txo mus rau 0.02 feem pua, thiab qhov poob ntawm hlau oxide nplai yog txo. Nws yog 0.7 feem pua, tus nqi txiav yog 0.05-0.1 feem pua, thiab cov khoom tiav tiav mus txog 99 feem pua. Txhim kho cov khoom ntawm cov rolls, siv cov roj lubricants kom ntev lub neej ntawm cov yob; thiab nruab ib lub tshuab hloov ceev ceev kom txo tau tag nrho cov yob hloov lub sij hawm los ntawm 10 mus rau 15 feem pua ​​​​ntawm tag nrho cov sij hawm ua hauj lwm mus rau 4 feem pua, thiab cov dov zeb ua hauj lwm tus nqi nyob rau hauv ib co kev cob qhia tau nce mus rau 90 feem pua.
