txheej txheem ntau lawm:
1. Uncoiling: Muab lub kauj rau hauv lub uncoiler thiab theem nws.
2. Pre- straightening: Ua ntej-txiav thiab pre-weld straightening ntawm steel sawb ntawm ib tug kauv leveling tshuab.
3. Kev sib sau: Siv HF vuam tshuab los nias lub steel sawb mus rau hauv cov yeeb nkab zoo, ces hla nws los ntawm qhov puag ncig.
4. High zaus welding: Siv lub tshuab vuam ntau zaus los vuam cov yeeb nkab welded.
5. Loj square: Tshawb xyuas lub welded raj loj square thiab kho cov duab los ntawm sizing tshuab.
6. Internal welding tu: Siv lub taub hau dej txias kom tshem tawm cov slag sab hauv thiab vuam sparks.
7. Sab nrauv txheej: Siv lub tshuab pickling thiab denoising los pleev xim rau sab nrauv ntawm cov yeeb nkab welded.
8. Zinc plating: Siv high-voltage zinc plating tshuab los ua kom cov corrosion kuj ntawm cov yeeb nkab welded.
9. Kev tshuaj xyuas: Siv cov cuab yeej kuaj kev tshaj lij los tshuaj xyuas cov yeeb nkab welded, thiab coj cov kev kho mob sib xws lossis tsis lees txais kev ntsuas raws li qhov yuav tsum tau ua.
10. Ntim: Ntim cov yeeb nkab welded nrog cov khoom ntim tshwj xeeb los tiv thaiv cov yeeb nkab.
HFW welded yeeb nkab muaj qhov tseeb qhov tseeb, siab phab ntsa tuab, kev ua haujlwm zoo ib yam, kev ua tau zoo thiab kev ua haujlwm zoo thiab cov khoom siv kho tshuab, nrog rau perforation, perforation, perforation, thiab lwm yam.
Vuam siab yog ib qho tseem ceeb ntawm cov txheej txheem vuam. Tom qab ob lub npoo ntawm lub raj khoob yog rhuab mus rau qhov kub thiab txias, cov hlau zoo sib xws yog tsim los ntawm kev ua ntawm extrusion quab yuam, uas yog, kev sib nrig sib crystallization thiab vuam. Qhov loj ntawm vuam siab cuam tshuam lub zog thiab toughness ntawm vuam. Yog hais tias lub vuam siab thov me me, cov hlau vuam npoo tsis tuaj yeem raug nias siab, thiab cov hlau tsis muaj hlau thiab cov hlau oxides seem hauv cov vuam tsis yooj yim tawm vim qhov tsis tshua muaj siab, lub zog vuam raug txo, thiab nws yog yooj yim tawg tom qab kev ntxhov siab; Yog tias lub siab siab dhau lawm Thaum lub vuam kub ncav cuag, feem ntau ntawm cov hlau yog extruded, uas tsis tsuas yog txo lub zog ntawm cov vuam, tab sis kuj ua rau muaj qhov tsis xws luag xws li ntau dhau ntawm sab hauv thiab sab nraud burrs lossis lap welding. Yog li ntawd, qhov zoo tshaj plaws vuam siab sib xws rau nws yuav tsum tau txais nyob rau hauv kev xyaum raws li ntau yam thiab specifications. Raws li kev paub dhau los, chav vuam siab feem ntau yog 20 ~ 40MPa.
