Cov raj hlau tuaj yeem muab faib ua ntau txoj hauv kev, thiab los ntawm kev tsim khoom, lawv tuaj yeem muab faib ua cov welded steel raj thiab seamless steel raj. Kab lus no tsom mus rau kev npaj thiab teem caij teeb meem hauv kev tsim cov seamless steel raj. Txij li thaum kev npaj ntau lawm thiab kev teem caij ntawm seamless steel tubes yog ze ze rau lawv cov txheej txheem tsim khoom, kev paub txog cov txheej txheem tsim khoom tuaj yeem pab txhawb kev ua tiav ntawm cov phiaj xwm ntau lawm thiab kev teem sijhawm.
Cov txheej txheem ntau lawm ntawm seamless steel raj feem ntau muaj kev kho kub deformation thiab kev kho mob khaub thuas. Kub deformation kev kho mob yuav tsum tsis tu ncua ua steel billets nyob rau hauv high-kub tej yam kev mob los tsim ib lub plhaub, siv cov cuab yeej xws li piercers, nruam casting tshuab, thiab stretch txo mills.
Kev kho mob khaub thuas, tseem hu ua cov txheej txheem ua tiav, yog hais txog cov txheej txheem ntawm kev hloov lub plhaub rau hauv lub raj hlau tiav hauv cov xwm txheej ib txwm muaj. Cov txheej txheem no suav nrog kev ua kom txias, ncaj, txiav, ntsuas qhov tsis zoo, thiab lwm yam.
Muaj ntau txoj hauv kev rau seamless steel raj, suav nrog kub dov, txias dov, thiab kos duab txias. Txawm li cas los xij, feem ntau cov neeg xaj xaj xav tau cov txheej txheem kub dov. Cov txheej txheem kub rolling ntws ntawm seamless steel raj yog qhia hauv daim duab 1, uas muaj cov raj khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob dov cov txheej txheem, rov ua kom sov hauv qhov cub, ua tiav dov, thiab thaum kawg, ua tiav rau hauv lub raj seamless steel tiav.
