ST37 Carbon steel kauj

Pickling phaj yog ua los ntawm high-zoo kub-kuav los tiag ntawv raws li raw khoom. Tom qab lub pickling chav tsev tshem tawm cov oxide txheej, trims thiab ua tiav, qhov zoo ntawm qhov chaw thiab kev siv (feem ntau yog txias-tsim los yog stamping kev ua tau zoo) nyob nruab nrab ntawm kub dov thiab txias dov Cov khoom nruab nrab ntawm cov phaj yog ib qho zoo tagnrho hloov rau ib co kub dov daim hlau thiab txias dov daim hlau. Piv nrog cov phaj kub-kuav los tiag, lub ntsiab zoo ntawm cov phaj pickled yog: 1. Zoo nto zoo. Vim tias cov ntawv kub dov cov ntawv tshem tawm cov nplai oxide, qhov zoo ntawm cov hlau zoo tuaj, thiab nws yooj yim rau vuam, roj thiab pleev xim. 2. Qhov tseeb qhov tseeb yog siab. Tom qab leveling, lub phaj zoo tuaj yeem hloov mus rau qee qhov, yog li txo qhov sib txawv ntawm qhov tsis sib xws. 3. Txhim kho qhov chaw tiav thiab txhim kho cov nyhuv zoo. 4. Nws tuaj yeem txo qhov kev ua qias tuaj ib puag ncig los ntawm cov neeg siv cov khoom tawg. Piv nrog cov ntawv txias-dov, qhov zoo ntawm cov nplooj ntawv pickled yog tias lawv tuaj yeem txo cov nqi yuav khoom zoo thaum ua kom ntseeg tau qhov kev xav tau zoo. Ntau lub tuam txhab tau muab cov kev xav tau siab dua thiab siab dua rau kev ua haujlwm siab thiab tus nqi qis ntawm cov hlau. Nrog rau kev nce qib ntawm cov hlau dov technology, qhov kev ua tau zoo ntawm cov ntawv kub dov tau nce mus txog ntawm cov ntawv txias-dov, yog li ntawd "hloov txias nrog cua sov" yog technically paub. Nws tuaj yeem hais tau tias cov phaj pickled yog cov khoom lag luam uas muaj kev ua tau zoo-rau-tus nqi sib piv ntawm cov phaj txias-dov thiab cov phaj kub-kub, thiab muaj kev lag luam zoo tsim kev cia siab. Txawm li cas los xij, kev siv cov phaj pickled hauv ntau qhov kev lag luam hauv kuv lub teb chaws nyuam qhuav pib. Kev tsim cov ntawv pov thawj kev tshaj lij tau pib thaum lub Cuaj Hlis 2001 thaum Baosteel's pickling ntau lawm kab tau muab tso rau hauv kev ua haujlwm.
