Cov khaub thuas dov npuag yog cov hom hlau ua tau los ntawm cov yas deformation ntawm kub dov cov hlau hauv cov kab txias dov. Raws li cov txheej txheem ntawm cov txheej txheem no cov khoom muaj tighter dimensional tolerances, zoo dua saum npoo zoo thiab cov yam ntxwv zoo dua li piv nrog cov ntaub sov npuag. Tsis tas li ntawd, los ntawm cov dov txias nws muaj peev xwm kom tau txais cov ntaub npog nyias nyias uas tam sim no tsis muaj nyob rau cov khoom kub dov (ntau dua 0.8-1.0mm).
Kev faib tawm, ntau yam thiab cov khoom ntawm txias txias ntawm cov yeeb yaj kiab
Cov qauv ntawm cov teb chaws txawv hais txog cov kev xav tau rau cov khaub thuas kuav los tiag cov khoom lag luam steel, xws li EN 10130, EN 10268, EN 10209, ASTMA1008 / A1008M, DSTU 2834, GOST 16523, GOST 9045, GOST 17066, thiab lwm yam, ntxiv cov sib txawv thiab ntau thiab tsawg ntawm cov khoom lag luam no, lawv daim ntawv thov (profiling, txias tsim, pleev xim, siv dav dav, thiab lwm yam), cov khoom siv cav, thaj chaw zoo thiab lwm yam tsis suav.
Cov qauv rau cov khaub noom txias txias
Qee qhov ntawm cov txheej txheem feem ntau ntawm European rau kev tsim cov khaub thuas dov txias yog EN 10130, EN 10268 thiab EN 10209.
EN 10130 yog siv rau kev muag cov pa roj carbon txias uas tsis muaj qis dua cov hlau ntawm hom DC01, DC03, DC04, DC05, DC06, DC07 rau kev kho siab txias, tsis muaj txheej, nrog cov hlau dov dav tsawg kawg 600 hli thiab qhov tsawg kawg nkaus tuab ntawm 0.35 hli Cov.

Cov neeg tseem ceeb ntawm cov khaub thuas txias txias yog kev tsim kho, kev tsim kho tshuab, kev tsim kho tsheb, hlau thiab organic coated khoom thiab khoom vaj khoom tsev.
Hauv qhov kev tsim kho, txias kuav los tiag hlau yog siv dav los ua cov hlab kaw thiab cov ntawv xa khoom, qib ntsej muag thiab cov qauv hlau. Lub ntsiab lus tseem ceeb uas cov khaub thuas txias yuav tsum tau muaj xws li tuab yam tsawg kawg thiab ua kom hnyav li 25 tons. Lub zog muaj zog, cov hlau me uas tsis tshua muaj siab ua rau muaj ntau dua vim lawv tuaj yeem txo qhov kev siv ntawm cov hlau thiab nce load-cov kabmob muaj peev xwm ntawm steel qauv.
Txias kuav los tiag steel chev ntau lawm
Cov khoom pib pib los ntawm kev uas tau muab cov khaub thuas txias los ua ib txheej kub kub txias. Lub kauj hlau ua ntej undergoes acid pickling thiab ntxuav hauv tas li pickling kab kom tshem tawm cov paug los ntawm daim ntawv saum npoo.
Cov coils tom qab ntawd tau txau rau hauv kev nruam thiab rov qab txias txias yob mills, qhov chaw uas lawv tau hla cov yas deformation tsis muaj qhov ua ntej mus txog rau ntu ntu ntawm cov khoom ua tau raws li qhov kev txiav txim xav tau. Yog li, sab nraud deformation quab yuam ua rau muaj kev hloov pauv ntawm tus qauv thiab yog li ntawd hauv cov yam ntxwv ntawm cov hlau, uas yog hu ua txias yam tawv tawv. Nws yog qhov tshwm sim los ntawm cov hlau duct nyuaj dua thiab muaj zog dua, tab sis muaj qis dua plasticity thiab viscosity, txawm hais tias cov yam ntxwv no yuav txawv nyob ntawm ntu hla ntawm coil. Yog li ntawd, ib zaug lawv tawm hauv lub zeb, feem ntau cov ntaub thaiv txias txias mus los ntawm kev kho cua sov, ua kom muaj kev kub ntxhov, hauv cov qhov cub qhov cub lossis hauv cov kab txuas ntxiv.
Hauv theem kawg ntawm kev tsim khoom, cov khaub thuas txias thiab cov kav hlau txuas tau hloov mus rau txoj kab winding, mus dhau ntawm daim tawv nqaij hla thiab cov txheej txheem tawv tawv, hlais thiab hla cov kab txiav, tom qab ntawd los soj ntsuam thiab ntim. Thaum ua tiav cov txheej txheem, cov kauj yuav raug coj mus rau cov khoom ntim khoom tiav lawm.
