Melting thiab Casting
Cov khoom siv raw uas ua rau cov khoom tsis muaj steel hlau yog muab tso ua ke thiab yaj hauv lub cub hluav taws xob loj. Nyob rau hauv cov kauj ruam no, khaus kub yog thov nruj rau 8 mus rau 12 teev. Thaum lub melting tiav, cov hlau molten yog cam khwb cia rau hauv cov khoom uas xav tau semi-tiav lawm. Qee cov ntaub ntawv los yog cov duab feem ntau muaj xws li billets, round billets (rectangles), billets (uas tuaj yeem yog puag ncig lossis square), pas nrig thiab lub voj voog.
tsim
Nyob rau theem ob, lub semi-finished seem steel mus los ntawm ib tug series ntawm txoj kev tsim. Piv txwv li, stainless hlau yog kub dov (rhuab thiab dhau los ntawm cov menyuam loj loj). Cov pob zeb thiab cov pob zeb tau hloov mus rau hauv cov pas nrig thiab cov xaim. Cov phaj, ntawm qhov tod tes, yog ua rau hauv daim hlau, strips, los yog ntawv. Nws yog ib qho uas yuav tsum tau hloov lub semi-tiav steel duab rau hauv ib lub bar, raws li nws yog ntau yam stainless hlau zoo li (nws los ntawm ntau qib thiab ntau thiab tsawg). Muaj round, square, octagonal thiab hexagonal rods, txhua tus haum rau ntau hom kev siv.
Kev kho cua sov
Nyob rau hauv cov kauj ruam no, ntau yam stainless hlau daim ntawv yog kom huv si annealed. Annealing yog lwm lub npe rau kev kho cua sov ntawm stainless hlau los ntawm cua sov thiab txias rau hauv ib puag ncig tswj. Lub hom phiaj ntawm kev kho cua sov no yog txhawm rau txo cov kev ntxhov siab uas muaj nyob hauv cov hlau tsis huv thiab ua kom cov khoom muag muag kom haum rau ntau yam kev siv. Cov neeg ua haujlwm rau cov txheej txheem annealing yuav tsum tau ceev faj heev vim tias qhov kev hloov me me ntawm qhov kub, siab, lub sijhawm lossis qhov txias txias tuaj yeem ua rau cov khoom tsis ua haujlwm.
Kev tshem tawm
Thaum lub sij hawm annealing txheej txheem, ib tug npaum li cas ntawm scale tshwm nyob rau saum npoo ntawm stainless hlau. Qhov ntsuas no tuaj yeem raug tshem tawm siv ntau cov txheej txheem sib txawv uas suav nrog hu ua descaling. Pickling yog ib qho ntawm ntau txoj hauv kev los ua cov txheej txheem descaling.
Txiav
Cov ntaub ntawv semi-tiav, kub-kho, thiab descaled stainless hlau cov ntaub ntawv raug txiav rau hauv cov duab tshwj xeeb hauv cov kauj ruam no. Mechanical txiav yog ua nrog kev pab ntawm guillotine riam, blanking, nibbling, thiab high-ceev hniav.
Ua tiav
Kev ua tiav yog siv los pab cov khoom siv stainless hlau ua tiav nws qhov kos npe zoo nkauj txaus nyiam. Kev ua tiav kuj tseem xav tau los ua kom cov khoom siv stainless hlau du thiab yooj yim dua los ntxuav, uas yog ib qho tseem ceeb tshaj plaws hauv kev siv huv huv.
