Stainless hlau ua li cas?

Stainless hlau yog ib hom hlau alloy uas tau siv dav hauv ntau qhov kev lag luam vim nws cov khoom siv ntau yam thiab kev tiv thaiv corrosion. Txhawm rau ua cov hlau tsis muaj steel, muaj ob peb kauj ruam koom nrog hauv kev tsim khoom, uas peb yuav piav qhia hauv qab no.

1. Melting thiab refining

Thawj kauj ruam hauv kev ua cov hlau tsis muaj steel yog yaj cov ntaub ntawv raw hauv qhov cub. Cov khoom siv tseem ceeb hauv kev tsim cov hlau tsis muaj steel yog hlau ore, npib tsib xee, chromium, thiab carbon. Thaum cov ntaub ntawv yog melted ua ke, lawv yog poured rau hauv ib tug ladle thiab thauj mus rau ib tug refining chaw nres tsheb.

Ntawm qhov chaw refining, cov hlau yaj yog raug rau cov txheej txheem uas tshem tawm impurities thiab tsis xav tau gases. Cov txheej txheem no yog qhov tseem ceeb hauv kev ua kom cov khoom kawg ntawm kev ncaj ncees yog qhov zoo.

2. Casting

Tom qab refining, cov hlau melted ces poured rau hauv pwm los tsim ib qho khoom ntawm stainless hlau los yog dov tawm mus rau hauv cov nplooj ntawv sib txawv thicknesses. Muaj ntau hom pwm siv hauv casting stainless hlau, nrog rau cov xuab zeb, peev, thiab nruam casting pwm.

3. Rolling thiab tsim

Thaum cov hlau tsis muaj hlau tau raug muab pov tseg, nws tuaj yeem dov rau hauv cov duab sib txawv thiab ntau thiab tsawg. Rolling mills tuaj yeem tsim cov hlau rau hauv cov ntawv, phaj, tuav, thiab cov xov hlau, nyob ntawm tus neeg siv khoom xav tau. Cold-rolling thiab kub-dov yog ob txoj kev siv thaum lub sijhawm ua haujlwm no.

4. Kev kho cua sov thiab ua kom tiav

Tom qab dov thiab sib sau, cov hlau tsis muaj steel tau dhau los ua cov txheej txheem kho cua sov los kho nws cov qauv thiab txhim kho nws lub zog thiab hardness. Cov txheej txheem kev kho cua sov yuav tsum ua kom sov cov hlau mus rau qhov kub thiab txias kom ua tiav cov khoom xav tau.

Deg xov yog kauj ruam kawg hauv kev ua stainless hlau. Nws koom nrog cov txheej txheem xws li polishing, sib tsoo, thiab buffing, uas muab cov hlau tsis muaj steel nws tus yam ntxwv du thiab ci ci.

Hauv kev xaus, ua stainless hlau yog ib txoj kev nyuaj uas muaj ob peb kauj ruam. Txawm li cas los xij, nrog cov ntaub ntawv zoo, cov khoom siv, thiab cov neeg ua haujlwm txawj, stainless hlau tuaj yeem tsim nrog cov khoom zoo xws li kev tiv thaiv corrosion siab thiab kav ntev.
