Cov txheej txheem tsim khoom ntawm 314 stainless hlau xaim feem ntau suav nrog cov kauj ruam hauv qab no:
1.Raw khoom xaiv: Thawj kauj ruam yog xaiv cov khoom siv raw uas tsim nyog uas ua tau raws li cov khoom siv tshuaj lom neeg thiab cov khoom siv kho tshuab rau 314 stainless hlau. Feem ntau, qhov no suav nrog kev xaiv cov hlau zoo nkauj lossis cov tuav uas tom qab ntawd yaj thiab ua kom zoo.
2.Melting thiab refining: Cov khoom siv raw xaiv tau yaj hauv lub cub tawg thiab tom qab ntawd ua kom zoo dua los ntawm cov txheej txheem xws li AOD (argon-oxygen decarburization) lossis VOD (lub tshuab nqus pa oxygen decarburization) kom tshem tawm cov impurities thiab kho cov tshuaj muaj pes tsawg leeg mus rau qib siab xav tau.
3.Casting: Cov hlau molten yog ces muab pov rau hauv billets los yog tuav siv nruam casting los yog ingot casting txoj kev. Tom qab ntawd cov cam khwb cia hlau yog dov rau hauv cov hlau rods.
4. Kub dov: Cov hlau rods yog rhuab mus rau ib tug kub kub thiab dhau los ntawm ib tug series ntawm rollers kom txo lawv txoj kab uas hla mus rau qhov xav tau loj. Cov txheej txheem no kuj tseem pab ua kom zoo dua cov qauv ntawm cov hlau, ua rau nws muaj zog thiab zoo ib yam.
5.Annealing: Cov hlau yog ces annealed tshem tawm cov residual stresses thiab txhim kho nws ductility thiab machinability. Annealing feem ntau yog ua nyob rau hauv qhov chaw tswj kom tsis txhob oxidation thiab ua kom cov cua sov zoo ib yam.
6.Cold drawing: Lub annealed hlau yog ces txias los ntawm ib tug series ntawm tuag kom ntxiv txo nws txoj kab uas hla thiab txhim kho nws nto tiav thiab mechanical zog.
7.Qhov kawg ntawm kev kho cua sov: Cov hlau yog tom qab ntawd kho cua sov kom ua tiav cov khoom kawg uas xav tau, xws li lub zog, hardness, thiab corrosion kuj.
8.Coiling thiab ntim: Cov kauj ruam kawg yog coil cov xaim mus rau spools lossis coils thiab ntim khoom xa tuaj.
Cov ntsiab lus tshwj xeeb ntawm cov txheej txheem tsim khoom yuav txawv nyob ntawm cov chaw tsim khoom thiab cov phiaj xwm kev thov ntawm cov hlau.
