Yuav ua li cas stainless hlau strips ua?

Stainless hlau daim kab xev yog ib yam ntawm cov khoom siv hlau dav siv nyob rau hauv ntau yam kev lag luam, paub txog nws zoo heev corrosion kuj, siab kub zog thiab mechanical zog. Yog li cas cov khoom tseem ceeb no ua li cas? Cov hauv qab no yuav qhia luv luv txog kev tsim khoom ntawm stainless hlau siv.

 

Kev npaj cov khoom siv raw

Kev tsim cov khoom siv stainless hlau pib nrog kev xaiv cov ntaub ntawv tsim nyog. Feem ntau, cov khoom tseem ceeb ntawm stainless hlau yog hlau, chromium thiab npib tsib xee, ntawm cov ntsiab lus chromium tsawg kawg yog 10.5%, uas ua rau cov hlau tsis muaj corrosion kuj zoo heev. Ntxiv nrog rau cov khoom tseem ceeb no, lwm cov ntsiab lus yuav raug ntxiv los txhim kho lawv cov khoom, xws li carbon, manganese, silicon, molybdenum, tooj liab, thiab lwm yam.

 

Nkag mus rau theem melting

Nyob rau hauv lub melting theem, cov khoom sib tov yog muab tso rau hauv ib tug hluav taws xob arc rauv los yog induction rauv rau melting. Qhov kub hauv qhov cub feem ntau ncav cuag li 1600 degrees Celsius. Lub molten kua hlau yog refined kom tshem tawm impurities thiab gases los ntawm nws.

 

Ncuav rau hauv lub tshuab nruam casting

Cov kua stainless hlau yog poured rau hauv lub nruam casting tshuab, thiab stainless hlau sawb yog tsim los ntawm cov txheej txheem nruam casting. Nyob rau hauv cov txheej txheem no, kua stainless hlau yog nruam nruam mus rau hauv ib tug rotating pwm los tsim ib tug strip blank ntawm ib tug tej thickness. Qhov ntsuas cua txias thiab ntsuas kub ntawm cov pwm muaj qhov cuam tshuam tseem ceeb ntawm qhov zoo thiab kev ua haujlwm ntawm cov sawb.

 

Nkag mus rau qhov kub dov theem

Lub billet yog kub dov los ntawm kub dov zeb los ua ib tug steel phaj nrog ib tug tej thickness thiab dav. Thaum lub sij hawm kub dov txheej txheem, steel phaj yog raug rau ntau yam dov thiab kub hloov kho kom tau raws li qhov xav tau qhov loj me thiab cov khoom.

 

Pickling theem

Nyob rau hauv cov txheej txheem no, stainless hlau sawb yog soaked nyob rau hauv ib tug acidic tov kom tshem tawm cov nto oxides thiab impurities. Qhov saum npoo ntawm stainless hlau sawb tom qab pickling yog smoother, uas muab lub hauv paus zoo rau tom qab txias dov thiab nto kho.

 

Qhov txias dov theem

Nyob rau theem no, stainless hlau sawb txuas ntxiv dov los ntawm lub tshuab txias kom ntxiv nws cov thickness thiab flatness. Cov txheej txheem txias dov tuaj yeem txhim kho qhov zoo ntawm qhov chaw thiab qhov tseeb ntawm stainless hlau sawb.

 

Qhov kawg theem

Tom qab cov txheej txheem tom qab kev kho mob xws li annealing, polishing thiab txiav, stainless hlau sawb thaum kawg ua tiav cov txheej txheem tsim khoom. Cov txheej txheem annealing tuaj yeem tshem tawm qhov kev ntxhov siab hauv cov hlau tsis huv, txhim kho nws cov yas thiab tawv; Polishing txheej txheem tuaj yeem ua rau saum npoo ntawm stainless hlau sawb ntau du thiab ci; Cov txheej txheem txiav txiav cov hlau tsis xeb hlau mus rau qhov xav tau ntev thiab dav raws li xav tau.

 

Hauv cov ntsiab lus

Cov txheej txheem tsim khoom ntawm stainless hlau sawb suav nrog kev npaj cov khoom siv raw, melting, nruam casting, kub dov, pickling, txias dov thiab tom qab kho thiab lwm yam txuas. Txhua kauj ruam yuav tsum muaj kev tswj xyuas cov txheej txheem tsis raug thiab cov qauv zoo los xyuas kom meej tias cov khoom kawg ua tau raws li qhov yuav tsum tau ua. Kev siv dav ntawm stainless hlau strips yog vim nws zoo heev corrosion kuj thiab txhua yam khoom, thiab kev tswj zoo ntawm cov txheej txheem tsim khoom yog tus yuam sij kom ua tiav cov khoom no.
