Hauv kev lag luam roj thiab roj, cov kav dej seamless steel ua lub luag haujlwm tseem ceeb. Raws li ib tug high-precision, high-lub zog steel yeeb nkab, nws muaj peev xwm tiv taus ntau yam hnyav ib puag ncig xws li kev kub siab, siab kub, corrosion, thiab lwm yam., yog li nws yog dav siv nyob rau hauv kev thauj mus los pipelines thiab siab hlab ntsha nyob rau hauv tshiab zog teb xws li roj thiab natural gas.
1. Cov yam ntxwv
Seamless steel kav siv hauv cov roj thiab roj muaj cov yam ntxwv hauv qab no:
1. High precision: Seamless steel yeeb nkab muaj cov phab ntsa zoo ib yam thiab siab precision, uas tuaj yeem xyuas kom meej qhov smoothness thiab sealing ntawm cov yeeb nkab.
2. Lub zog siab: Txij li cov kav dej seamless steel tsis muaj welds, lawv muaj zog dua thiab tawv thiab tuaj yeem tiv taus qhov chaw hnyav xws li kev kub siab thiab kub.
3. Corrosion resistance: Cov kua qaub thiab alkali Cheebtsam hauv cov roj thiab cov nkev roj yuav ua rau corrosion rau steel kav, tab sis cov khoom siv hauv cov kav dej seamless steel siab dua, yog li nws muaj kev tiv thaiv corrosion zoo dua thiab tuaj yeem ua kom muaj kev ua haujlwm zoo ntawm cov kav dej.
4. Lub neej ntev: Vim yog cov txheej txheem tsim khoom nruj ntawm seamless steel kav, lawv lub neej kev pab cuam tuaj yeem lav tau ntev rau ntau xyoo, yog li txo qhov zaus ntawm kev hloov thiab cov nqi sib xws.
2. Cov txheej txheem tsim khoom
Kev tsim cov txheej txheem ntawm seamless steel kav rau cov roj thiab cov roj av feem ntau suav nrog cov kauj ruam hauv qab no:
1. Smelting: Ntxiv molten hlau rau hauv lub qhov cub rau smelting kom tshem tawm impurities thiab gases kom ntseeg tau lub purity ntawm cov yeeb nkab steel.
2. Nruam casting: Lub molten hlau yog poured rau hauv lub nruam casting tshuab kom solidify los ua ib tug steel billet.
3. Rolling: Lub steel billet yog raug rau ntau cov txheej txheem dov kom deform nws thiab tsim cov qauv tubular xav tau.
4. Perforation: Cov yeeb nkab steel dov yog perforated los ntawm lub tshuab perforation los ua cov phab ntsa ntawm cov yeeb nkab steel seamless.
5. Kev kho cua sov: Kev kho cua sov yog ua rau ntawm cov yeeb nkab perforated seamless steel kom tshem tawm cov kev ntxhov siab sab hauv thiab txhim kho nws cov khoom siv kho tshuab.
6. Kev Ua tiav: Nto xov thiab kev ua tiav ntawm cov kav dej kub-kho seamless steel kav kom tau raws li cov neeg siv khoom xav tau.
7. Kev tshuaj xyuas: Kev tshuaj xyuas nruj yog ua tiav ntawm cov kav dej seamless steel, nrog rau qhov tseeb qhov tseeb, phab ntsa thickness uniformity, sab hauv thiab sab nrauv zoo, thiab lwm yam, kom ntseeg tau cov khoom zoo.
Nyob rau hauv luv luv, seamless steel kav siv nyob rau hauv cov roj thiab roj teb, raws li ib tug high-precision, high-strength steel yeeb nkab khoom, ua lub luag hauj lwm tseem ceeb nyob rau hauv kev sib txuas lus pipelines thiab siab hlab ntsha nyob rau hauv lub zog teb.
