Metallurgical Product Description
Seamless ntshiab calcium hlauplays lub luag haujlwm tseem ceeb hauv casting thiab steelmaking. Nws tuaj yeem yaj tau zoo dua thiab nqus cov hmoov txhuas. Nws yog ib yam khoom uas muaj kev siv tau zoo heev, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, thiab cov txiaj ntsig kev lag luam siab heev.
Cov tub ntxhais hlau tau siv txij li xyoo 1970 los cuam tshuam nrog cov hlau molten. Nrog rau kev txhim kho ntawm cov phaj nyias txuas ntxiv mus rau kev siv thev naus laus zis hauv xyoo 1990, qhov zoo ntawm seamless calcium hlau tau lees paub los ntawm feem coob ntawm cov hlau mills thiab yog li tau txais kev nyiam thoob plaws ntiaj teb. Niaj hnub no, kev ua lag luam sib koom ntawm cov calcium hlau ntshiab hauv North America tau tshaj 70%, thiab European lag luam kuj tau mus txog 40%, cov xov hlau cored tau ua tiav cov txiaj ntsig zoo ntawm kev lag luam thiab kev sib raug zoo xyoo dhau los.

ZhenAn Metallurgy muaj kev paub dhau los hauv kev tsim khoom thiab tuaj yeem muab cov khoom lag luam txhim khu kev qha.
ntawm seamless calcium technology
Cov khoom lag luam zoo hloov pauv hauv steelmaking deoxidation, uas muaj peev xwm txhawb kev kho calcium uas cuam tshuam rau cov hlau molten zoo dua thiab ruaj khov.
qhov zoo ntawm seamless calcium cored hlau
Nws zam kev qhia txog cov ntsiab lus tsis zoo (S, P, C, Si) hauv cov hmoov calcium-cored hlau, kov yeej qhov tshwm sim uas cov hmoov calcium-cored hlau yog hollow lossis cov hmoov tseem ceeb ntawm cov hmoov tsis sib xws, uas yuav cuam tshuam rau kev pub mis. Nyob rau tib lub sijhawm, txij li cov hlau cored yog seamless, nws yuav tsis coj cua mus rau hauv cov hlau molten, uas kuj txo cov txaws tom qab nkag mus rau hauv cov hlau molten.
Nrog kev pab los ntawm cov hlau feeder, molten steel yog input kom ceev li sai tau, melting thiab dissolving tob nyob rau hauv lub molten steel, ua si lub luag hauj lwm ntawm deoxidation, desulfurization, thiab tshem tawm ntawm inclusions. Nyob rau tib lub sijhawm, qhov muaj pes tsawg leeg tuaj yeem raug kho kom zoo, nce cov txiaj ntsig ntawm cov hlau, tsis tshua muaj ntiaj teb, thiab lwm yam, thiab muaj peev xwm ua kom muaj kev ruaj ntseg ntawm cov khoom sib xyaw. Txo cov nqi ntawm cov khoom muaj txiaj ntsig ntxiv nrog rau txo cov nqi kho kom zoo.
