Lub tshuab txawv teb chaws yob txoj kev siv tshuab muaj keeb kwm ntau tshaj 100 xyoo thiab tau muab faib ua peb theem.
Thawj theem (1838-1909)yog lub sijhawm tshawb nrhiav thiab kev sim ntau lawm.Nyob rau theem no, kev tshawb fawb ntawm yob txoj kev tshawb xav thiab txias-tsim steel yog nce qeeb.Nrog rau txoj kev loj hlob sai ntawm kev lag luam tsheb thauj mus los, cov hlau txias uas tsim los ntawm cov txheej txheem yob tuaj yeem ua tsis tau raws li cov neeg siv khoom xav tau.
Theem II (1910-1959)yog theem ntawm kev tsim thiab maj mam popularizing cov txheej txheem yob txoj kev.
Qhov thib peb theem (los ntawm 1960 txog rau tam sim no)yog theem ntawm kev loj hlob sai ntawm yob txoj kev ntau lawm.Txoj kev loj hlob ntawm txawv teb chaws txias-tsim steel ntau lawm tuaj yeem suav nrog ntau yam:
1).Kev tsim tawm tseem nce ntxiv
Txij li thaum xyoo 1960, cov khoom tsim tawm ntawm txawv teb chaws txias-tsim steel tau nce sai heev.Qhov no yog qhov sib txawv.Raws li kev txheeb cais ntawm cov hlau ua txias txias hauv ntau lub teb chaws nyob rau xyoo dhau los, cov khoom tsim los ntawm cov hlau txias thiab cov khoom siv hlau tau ruaj khov ntawm ib qho piv txwv.Nws yog 1.5: 100 txog 4: 100.Piv txwv li, txoj kev loj hlob txoj kev npaj tsim los ntawm yav dhau los Soviet Union nyob rau hauv 1975 tau teev tseg tias cov zis ntawm txias-tsim hlau nyob rau hauv 1990 yuav suav rau 4% ntawm cov zis steel.Nrog rau kev txhim kho cov txheej txheem ntawm cov khoom txias-tsim steel, cov khoom specifications thiab ntau yam txuas ntxiv mus, thiab cov khoom zoo txuas ntxiv txhim kho Cov peev txheej ntawm daim ntawv thov nthuav dav.Lub qub Soviet Union tau rov tswj hwm tus thawj txoj kev loj hlob nyob rau hauv 1979, hais tias nws yuav ncav cuag 5% nyob rau hauv 1990. Qee lub teb chaws kuj npaj yuav ua kom cov khoom siv txias txias.Tam sim no cov zis ntawm txawv teb chaws txias-tsim steel yog hais txog 10 lab tons hauv ib xyoos.Nws suav txog 3% ntawm lub ntiaj teb tag nrho cov hlau.
2).Kev tshawb fawb ua haujlwm tob zuj zus
Kev tshawb fawb ua haujlwm ntawm yob txoj kev xav, kev tsim cov txheej txheem thiab cov cuab yeej tsim khoom yog qhov tob hauv txawv teb chaws, thiab kev ua tiav tau ua tiav hauv kev tshawb fawb txog kev siv cov khoom siv txias txias.Piv txwv li, yav dhau los Soviet Union thiab Tebchaws Meskas tau siv cov khoos phis tawj hluav taws xob los kawm txog lub zog thiab lub zog tsis muaj zog hauv kev ua kom txias txias thiab tshawb xyuas cov txheej txheem deformation nrog kev siv hluav taws xob qis tshaj.
3).Cov txheej txheem tshiab tseem tshwm sim
Txij li thaum cov txheej txheem yob txoj kev tau kawm tiav hauv Tebchaws Meskas hauv xyoo 1910, tom qab ntau xyoo ntawm kev txhim kho thiab kev ua tiav, cov txheej txheem tsim tau dhau los ua neeg paub tab.Raws li cov txheej txheem kev lag luam thiab kev lag luam ntawm cov hlau ua kom txias hauv cov ntawv siv tau raug lees paub ntau ntxiv, cov hlau txias txias tau siv dav hauv ntau yam kev lag luam hauv lub tebchaws.Cov neeg siv muaj ntau thiab ntau qhov kev xav tau nruj rau qhov zoo ntawm cov hlau ua kom txias, thiab lawv xav tau kev sib txawv ntawm ntau yam thiab cov lus qhia tshwj xeeb.Qhov no txhawb kev txhim kho txuas ntxiv ntawm cov txheej txheem yob txoj kev kom tau raws li cov neeg siv khoom xav tau.Cov teb chaws txawv teb chaws tau txais cov txheej txheem yob txoj kev thiab tsim cov khoom siv sib xws.Vertical Roll Forming Tshuab nrog plug-in hom, tsim chav nrog centralized hloov ntawm kev sib sau yob yog hu ua CTA unit (Central Tool Adjustment), ncaj ntug tsim chav tsev.
4) Cov khoom lag luam muaj ntau zuj zus ntxiv, thiab cov qauv khoom tau hloov kho tas li.
Nrog rau txoj kev loj hlob ntawm txias-tsim steel ntau lawm thiab nthuav dav ntawm daim ntawv thov, ntau yam txias-tsim steel txuas ntxiv nce, cov qauv khoom yog hloov kho tas li, thiab cov qauv khoom tau maj mam txhim kho.Nrog rau kev tshwm sim tsis tu ncua ntawm cov thev naus laus zis tshiab, ntau yam ntawm cov ntaub ntawv billet thiab cov lus qhia tshwj xeeb tau nthuav dav.Tam sim no muaj ntau tshaj 10,000 ntau yam thiab specifications ntawm txias-tsim steel tsim nyob rau txawv teb chaws.Cov specifications ntawm txias-tsim steel ntau ntawm 10mm mus rau 2500mm, thiab thickness 0.1 hli ~ 32mm.Los ntawm qhov kev xav ntawm cov khoom ntawm cov hlau txias, nws yog cov pa roj carbon steel ua ntej xyoo 1970, uas suav txog ntau dua 90%.Txij li thaum xyoo 1970, los ntawm kev sib piv ntawm cov khoom siv thiab kev lag luam, kev siv cov khoom siv hluav taws xob muaj zog tsawg, cov hlau tsis muaj hlau thiab cov hlau tsis muaj steel ua rau cov khoom siv carbon zoo tib yam txo xyoo los ntawm xyoo, thiab feem ntau ntawm cov hlau alloy, high-strength low-alloy steel thiab stainless hlau khoom nce xyoo los ntawm lub xyoo.
