Dab tsi yog cov khoom faib ntawm steel rau boilers?
Los ntawm cov khoom siv, boiler steel phaj tuaj yeem muab faib ua ob pawg: tshwj xeeb carbon steel phaj thiab qis alloy kub-resistant steel phaj.
Boiler steel phaj siv rau hauv cov khoom ntawm cov tshuaj muaj pes tsawg leeg, tshwj xeeb tshaj yog rau phosphorus, sulfur thiab lwm yam teeb meem thiab chromium, npib tsib xee, tooj liab thiab lwm yam khoom seem muaj kev tswj hwm nruj; smelting yuav tsum tau zoo deoxidation thiab tshem tawm ntawm non-metallic inclusions los xyuas kom meej zoo plasticity thiab toughness; lub koom haum cov qauv yuav tsum tau uniformity, lub grain loj tswj nyob rau hauv ib tug tej yam ntau yam (feem ntau cia siab hais tias lub grain loj nyob rau hauv thaj tsam ntawm 3 mus rau 7); qhov zoo ntawm qhov chaw thiab qhov tsis xws luag sab hauv kuj tseem yuav tsum nruj; Ntxiv nrog rau qhov kub thiab txias ntawm cov khoom siv kho tshuab yuav tsum tau ua kom ntseeg tau Qhov zoo ntawm qhov chaw thiab sab hauv tsis zoo kuj muaj cov kev cai nruj; ntxiv rau chav tsev kub thiab kub kub txhua yam khoom yuav tsum tau lav.
Hauv GB / T713-2014 "boiler thiab siab hlab ntsha steel phaj" tus qauv qhia meej meej tias cov pa oxygen converter lossis hluav taws xob rauv smelting yuav tsum tau siv thiab yuav tsum tau ua kom zoo rau sab nraum lub qhov cub, thaum cov txheej txheem tsim khoom yuav tsum xyuas kom meej tias qhov nruam casting billet ingot nyob rau hauv lub kub dov compression piv tsis tsawg tshaj li 3.
