Dab tsi yog Cov Txheej Txheem Txheej Txheem Txias Rolled Sheet?

Cov ntawv txias dov muaj qhov zoo ntawm lub zog siab, qib siab nto, kev ua haujlwm zoo, zoo corrosion kuj, zoo heev qhov tseeb thiab ruaj khov lub cev, thiab yog dav siv nyob rau hauv kev tsim khoom ntawm nws pib qhov chaw, cov khoom siv hauv tsev, cov khoom siv hauv tsev, thiab chemical khoom thiab lwm yam kev lag luam.
Cov ntawv txias-dov yog cov khoom siv hlau uas tau dov thiab ncab ntawm chav tsev kub. Nws yog dav siv hauv kev tsim tsheb, khoom siv, kev tsim kho thiab ntau yam khoom siv.
Ua ntej yog kev npaj cov khoom siv raw: Cov txheej txheem tsim khoom ntawm cov ntawv txias-dov steel pib nrog kev npaj cov khoom siv raw. Ua ntej ntawm tag nrho cov, nws yog ib qhov tsim nyog yuav tau cov khoom zoo kub-kuav los tiag steel daim hlau. Cov hlau phaj no tau dov ntawm qhov kub thiab txias, muaj zog hardness thiab muaj zog, thiab muaj kev ua tau zoo heev. Txhawm rau kom ntseeg tau qhov zoo ntawm cov hlau phaj, tshuaj lom neeg muaj pes tsawg leeg thiab kev ntsuas kev ua tau zoo ntawm cov tshuab kuj tseem yuav tsum tau.
Tom qab ntawd dov thiab txias: Thaum lub phaj hlau tuaj txog ntawm lub Hoobkas, nws mus dhau lub tshuab dov rau thawj zaug dov thiab ncab. Rolling mills compresses cov ntawv hlau mus rau qhov xav tau thickness thiab ua rau nws thinner thiab ntau uniform. Tom ntej no, chav tsev txias txias txias lub phaj steel sai sai coj nws mus rau qhov xav tau hardness thiab lub zog.
Annealing kev kho mob: Txij li thaum cov hlau phaj ua nkig heev tom qab txias, annealing yuav tsum tau kho. Thaum lub sij hawm annealing, cov nplooj ntawv steel raug rau qhov kub thiab txias kom lawv softer thiab ntau ductile. Tom qab annealing, steel phaj tuaj yeem ua tiav thiab zoo li yooj yim dua.
Trimming thiab txiav: Thaum lub phaj tau mus txog qhov xav tau ntawm hardness, lub zog thiab toughness, nws yuav tsum tau txiav thiab txiav. Trimming yog txiav thiab shaping ntawm cov npoo ntawm cov hlau phaj kom tau raws li qhov tshwj xeeb qhov ntev thiab geometric. Kev txiav yog txiav cov hlau phaj mus rau qhov xav tau ntev thiab dav.
Kev kho qhov chaw xaus: txias dov steel phaj yuav tsum tau kho deg. Qhov no suav nrog txoj hauv kev xws li pickling, polishing lossis txheej. Pickling tuaj yeem tshem tawm oxides thiab lwm yam impurities nyob rau saum npoo ntawm lub phaj steel los txhim kho nws cov tsos thiab corrosion kuj. Polishing tuaj yeem ua rau saum npoo ntawm cov hlau phaj du thiab zoo ib yam. Cov txheej tiv thaiv cov hlau phaj los ntawm corrosion thiab lwm yam kev puas tsuaj.
