Txias dov phaj yog cov khoom siv hlau tsim los ntawm cov ntawv hlau los yog cov coils rau cov txheej txheem dov ntawm lossis me ntsis hauv qab chav tsev kub. Cov txheej txheem no yog hu ua txias dov, thiab nws yog siv los tsim cov hlau nrog txhim kho qhov chaw tiav, nruj dua qhov ntev, thiab cov khoom siv kho kom zoo dua qub, piv rau cov hlau kub kub, uas muaj cov khoom zoo dua qub thiab zoo.
Lub sij hawm "txias dov steel" tuaj yeem npog ntau hom hlau, txhua tus muaj cov tshuaj sib txawv thiab cov yam ntxwv ua haujlwm kom tau raws li ntau yam kev siv. Cov hauv qab no yog qee yam hom txias dov steel:
Cold Rolled Carbon Steel: Qhov no yog ib qho ntawm ntau hom txias dov hlau thiab feem ntau yog siv rau hauv kev tsim cov khoom siv dav dav, cov kav dej, qhov chaw tsheb thiab cov khoom siv hlau dav dav. Nws feem ntau muaj lub zog siab thiab hardness.
Cold Rolled Stainless Hlau: Stainless hlau muaj hlau, chromium, thiab lwm yam alloying ntsiab uas muab kev tiv thaiv corrosion thiab kub kub. Cold-Rolled Stainless Steel yog siv rau hauv kev tsim cov khoom noj khoom haus, cov khoom siv tshuaj, cov khoom siv thiab lwm yam khoom uas yuav tsum tau muaj kev tiv thaiv corrosion.
Cold Rolled Alloy Steel: Alloy steel muaj cov alloying uas tsis yog hlau thiab carbon, xws li chromium, nickel, molybdenum, thiab titanium. Cov alloys no txhim kho cov khoom ntawm cov hlau, xws li lub zog, hnav tsis kam thiab corrosion kuj. Cold rolled alloy steels yog siv los tsim cov khoom siv muaj zog, cov kabmob, cov cuab yeej thiab cov khoom siv tsheb.
Cold Rolled Electrical Steel: Cov hlau no tshwj xeeb tsim los rau kev siv hluav taws xob thiab hluav taws xob xws li transformers thiab lub cev muaj zog. Nws feem ntau muaj tsawg permeability thiab siab tiv thaiv kom txo qis eddy tam sim no poob.
Cold Rolled Kub Forming Steels: Cov hlau no tshwj xeeb tshaj yog txias dov los muab lub zog siab thiab kub ua haujlwm rau cov txheej txheem kub txheej txheem hauv kev tsim tsheb, xws li tsheb lub cev.
Cold-Rolled High Strength Low Alloy Steels: Cov hlau no sib xyaw ua ke siab zog nrog zoo weldability thiab feem ntau siv hauv kev tsim tsheb, kev tsim choj thiab kev tsim kho.
Cold Rolled Strip Steel: Sawb steel yog nyias, dav sawb ntawm cov hlau uas feem ntau siv los ua cov khoom siv, rab chais hniav, thiab cov cuab yeej txiav.
