Qhov txawv ntawm Cold Rolled Steel thiab Kub Rolled Steel

Qhov txawv ntawm Cold Rolled Steel thiab Kub Rolled Steel

COLD ROLLED STEEL:

Qhov feem ntau ntawm cov hlau tau ntsib los ntawm kev ua hauj lwm hmoov txheej, cov khoom no yog dov los ntawm kev ua siab ntev thiab ua tiav zoo, haum rau stamping, sib sau, thiab kev ua haujlwm nruab nrab. Cov khoom no tuaj yeem khoov rau ntawm nws tus kheej yam tsis muaj cracking. Lub hauv paus zoo rau phosphate conversion txheej. Cov lus pom zoo ua ntej yog Ntxuav, Phosphate, yaug, thiab foob lossis deionize yaug.

HOT ROLLED STEEL:

Cov pa roj carbon tsawg yog tsim rau kev tsim, xuas nrig ntaus, vuam, thiab kos duab ntiav. Qhov saum npoo muaj cov nplai zeb ib txwm uas yuav tsum tau muab tshem tawm los yog tshuaj lom neeg ua ntej siv cov txheej txheem hloov dua siab tshiab los yog cov organic topcoat. Qhov zeb nplai no adheres tsis muaj zog rau cov hlau thiab tsim ib txheej ntawm cov khoom siv tiav thiab cov hlau substrate. Yog li, tag nrho cov khoom adhesion ntawm kev ua tiav ntawm cov nplai zeb yuav nyob ntawm qhov tsis muaj zog adhesion ntawm cov nplai zeb rau lub hauv paus hlau.

HOT ROLLED STEEL PICKLE THIAB OIL:

Cov khoom siv qis carbon tsawg los ntawm cov nplai zeb tau raug tshem tawm los ntawm acid pickling. Lub teeb roj yog siv tom qab cov kua qaub pickling los tiv thaiv corrosion ntawm cov hlau. Cov khoom no muaj ib tug du nto, haum rau stamping, kos duab, thiab pretreatment ua ntej txheej.
