Stainless hlau seamless kav yog tsim los ntawm ob peb kauj ruam, xws li:
- Melting: Thawj kauj ruam yog yaj cov hlau tsis huv hauv lub tshuab hluav taws xob arc rauv, uas tom qab ntawd ua kom zoo dua thiab kho nrog ntau yam alloys kom ua tiav cov khoom xav tau.
- Nruam Casting: Cov hlau molten yog tom qab ntawd nchuav rau hauv lub tshuab nruam nruam, uas ua rau lub zog "billet" lossis "bloom" uas muaj cov duab thiab qhov loj me.
- Cov cua sov: Cov khoom siv hluav taws xob tau muab tso rau hauv qhov cub kom sov li ntawm 1100-1250 ° C kom nws tuaj yeem ua tau yooj yim thiab npaj rau kev ua haujlwm ntxiv.
- Piercing: Lub rhuab billet yog ces pierced nrog ib tug taw tes mandrel los tsim ib tug hollow raj.Cov txheej txheem no hu ua "piercing."
- Rolling: Lub raj hollow yog dov rau ntawm mandrel zeb kom txo nws txoj kab uas hla thiab phab ntsa thickness rau qhov loj me.
- Kev kho cua sov: Cov yeeb nkab seamless yog tom qab ntawd kho cua sov los txhim kho nws lub zog thiab tawv.Qhov no suav nrog cua sov cov yeeb nkab mus rau qhov kub ntawm 950-1050 ° C, tom qab ntawd txias sai hauv dej lossis cua.
- Kev Ua tiav: Tom qab kev kho cua sov, cov yeeb nkab seamless yog ncaj, txiav kom ntev, thiab ua tiav los ntawm polishing lossis pickling kom tshem tawm cov impurities saum npoo thiab txhim kho nws cov tsos.
- Kev Xeem: Cov kauj ruam kawg yog sim cov yeeb nkab rau ntau yam khoom, xws li hardness, tensile lub zog, thiab qhov tseeb, kom ntseeg tau tias nws ua tau raws li cov qauv xav tau.
Thaum cov yeeb nkab tau dhau tag nrho cov kev ntsuas uas yuav tsum tau ua, nws tau npaj xa mus rau cov neeg siv khoom.Tag nrho cov txheej txheem yog ua tib zoo saib xyuas thiab tswj xyuas kom cov yeeb nkab seamless ua tau raws li cov qauv tsim nyog.
