Cov Hlau DOM Round Tubing tuaj yeem siv rau hauv qhov chaw kub kub
Jan 27, 2025
Steel DOM (Drawn Over Mandrel) Round Tubing tuaj yeem siv rau hauv qhov chaw kub kub, tab sis nws qhov tsim nyog nyob ntawm ntau yam.
1. Cov khoom siv hlau
Hom steel siv nyob rau hauv tubing plays lub luag haujlwm tseem ceeb. Cov pa roj carbon steel DOM tubing feem ntau tuaj yeem tiv taus qhov kub thiab txias txog li ntawm 400 - 500 degree (752 - 932 degree F) nyob ntawm cov ntsiab lus carbon thiab lwm yam alloying. Ntawm cov kub no, nws cov khoom siv tshuab pib hloov pauv. Rau siab dua - kub daim ntaub ntawv, alloy steels yog ntau haum. Piv txwv li, chromium-molybdenum alloy steel DOM tubing tuaj yeem tswj qhov kub txog li 600 - 700 degree (1112 - 1292 degree F) lossis siab dua. Cov alloying ntsiab lus no muab kev tiv thaiv zoo dua rau softening thiab tswj cov tubing txoj kev ncaj ncees.
2. Thaum tshav kub kub - kev kho mob thiab txheej
Thaum tshav kub kub zoo - kev kho mob tuaj yeem txhim kho qhov kub thiab txias ntawm cov tubing. Annealing thiab normalizing txheej txheem tuaj yeem pab daws kev ntxhov siab sab hauv thiab txhim kho cov khoom muaj peev xwm tiv taus thermal cycling. Tsis tas li ntawd, cov coatings tuaj yeem muab cov txheej txheem tiv thaiv ntxiv. Ceramic coatings, piv txwv li, tuaj yeem ua raws li thermal teeb meem, txo tus nqi ntawm cov cua kub hloov mus rau hauv cov raj thiab tiv thaiv nws los ntawm oxidation thiab lwm yam kub-kub degradation txheej txheem.
3. Kev txiav txim siab ntawm daim ntawv thov
Nyob rau hauv ib puag ncig kub, lub peev xwm thauj khoom ntawm lub raj yuav hloov. Nws yog ib qho tseem ceeb uas yuav tau xav txog lub siab thiab mechanical loads lub tubing yuav ntsib. Yog tias cov tubing siv rau kev hloov cov kua dej, qhov nthuav dav ntawm cov tubing vim cua sov thiab cov peev xwm hloov pauv ntawm cov kua dej kuj yuav tsum tau coj mus rau hauv tus account kom muaj kev nyab xeeb thiab ua haujlwm zoo.
