Seamless Ntshiab Calcium Cored Hlau Nrog Zoo Zoo

Seamless ntshiab calcium cored hlau muaj ib lub hauv paus ntshiab calcium core thiab ib txheej hlau txheej. Lub hauv paus txheej txheej yog high-purity calcium hlau, thiab txheej txheej yog seamlessly coated nrog ib tug tshwj xeeb hlau cov ntaub ntawv (xws li txhuas hlau sawb) los xyuas kom meej stability thiab kev ncaj ncees ntawm cov tub ntxhais hlau calcium. Cov qauv no ua rau seamless ntshiab calcium cored hlau los ua lub luag haujlwm zoo dua hauv cov txheej txheem steelmaking.

Lub purity ntawm lub hauv paus ntshiab calcium core yog siab li 97%, kom ntseeg tau qhov sib xws thiab ruaj khov ntawm cov tshuaj calcium kev kho mob. Cov txheej txheem tshwj xeeb yog siv rau cov txheej txheem seamless, zam qhov khoob uas tshwm sim los ntawm cov txheej txheem txheej txheem, thiab tiv thaiv cov khoom kom tsis txhob muaj oxidized thiab tsis zoo los ntawm huab cua. Vim yog siv cov txheej txheem seamless thiab hauv qab pub mis, cov calcium hlau tuaj yeem ncav cuag hauv qab ntawm lub ladle thiab yaj sai sai, txhim kho cov calcium rov qab zoo heev. Kev siv seamless ntshiab calcium cored hlau tuaj yeem ua kom yooj yim rau cov txheej txheem smelting, txo tus nqi ntawm cov khoom muaj txiaj ntsig ntxiv, thiab txo cov nqi kho kom zoo.

Seamless ntshiab calcium cored hlau yog dav siv nyob rau hauv ntau yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv smelting, casting thiab steel dov. Nyob rau hauv cov txheej txheem steelmaking, seamless ntshiab calcium cored hlau ua raws li ib tug deoxidizer thiab muaj peev xwm hnov ​​​​mob nrog oxygen nyob rau hauv molten steel los tsim calcium oxide, yog li txo cov pa oxygen hauv cov hlau molten. Deoxidation pab txhim kho lub purity thiab zoo ntawm cov hlau, txo qhov tsim ntawm non-metallic inclusions, thiab txhim kho cov neeg kho tshuab zog thiab corrosion kuj ntawm hlau. Cov calcium uas nyob rau hauv seamless ntshiab calcium cored hlau kuj tuaj yeem hnov ​​​​mob nrog sulfur hauv cov hlau molten los tsim cov calcium sulfide. Calcium sulfide muaj cov ntsiab lus melting tsawg thiab yooj yim tshem tawm ntawm cov hlau molten, yog li txo cov ntsiab lus ntawm cov sulfur hauv cov hlau molten. Desulfurization pab txo cov kub brittleness ntawm hlau thiab txhim kho cov khoom siv kho tshuab thiab ua cov khoom ntawm cov hlau. Los ntawm kev ntxiv seamless ntshiab calcium cored hlau, morphology thiab kev faib tawm ntawm cov khoom siv hauv cov hlau tuaj yeem hloov pauv. Cov inclusions ua me thiab ntau dispersed, uas yuav pab txhim kho cov neeg kho tshuab zog thiab corrosion kuj ntawm hlau.

Nyob rau hauv tus txheej txheem ntawm cam khwb cia hlau ntau lawm, seamless ntshiab calcium cored hlau yuav siv tau rau desulfurization ntawm molten hlau. Los ntawm kev txo cov sulfur cov ntsiab lus nyob rau hauv molten hlau, qhov zoo thiab kev ua tau zoo ntawm cam khwb cia hlau tuaj yeem txhim kho. Seamless ntshiab calcium cored hlau kuj tseem siv tau rau hauv spheroidization thiab inoculation txheej txheem ntawm cam khwb cia hlau. Spheroidization pab tsim spheroidal graphite thiab txhim kho lub zog thiab toughness ntawm cam khwb cia hlau. Inoculation pab ua kom cov graphite thiab matrix qauv hauv cam khwb cia hlau, ntxiv txhim kho kev ua haujlwm ntawm cam khwb cia hlau.
