siab carbon chrome
A ferro alloy composed mainly of silicon, chromium and iron. Also known as silicon ferro chrome alloy. It is mainly used as an intermediate alloy for the production of medium, low and micro-carbon iron by electro silicothermal process. Used in steelmaking as a deoxidizer (instead of ferro silicon) and as a chromium additive. Generally containing Cr>30%, Si>35%, qhov nyiaj pub rau hlau thiab me me ntawm impurities. Cov txheej txheem ntau lawm muab faib ua ob hom: ib-kauj ruam txoj kev (feem ntau hu ua "slag method" los yog "ore method") thiab ob-kauj ruam txoj kev (feem ntau hu ua "slag free method"). yog silica, chromium ore thiab coke. Cov khoom siv raw siv nyob rau hauv ob-kauj ruam smelting txheej txheem yog silica, carbon ferro chrome thiab steel chips. Ob txoj kev smelting siv coke los txo tus neeg sawv cev.
Silicon chrome yog cov khoom siv alloy feem ntau yog tsim los ntawm silicon thiab chromium. Silicon chrome feem ntau yog siv rau hauv cov hlau tsim thiab casting txheej txheem hauv kev lag luam metallurgical. Nws lub luag haujlwm tseem ceeb yog los ua cov khoom siv alloy los txhim kho cov khoom siv kho tshuab thiab hnav tsis kam ntawm cov hlau.
Silicon chrome tuaj yeem txhim kho qhov hardness, lub zog thiab corrosion kuj ntawm steel, ua rau cov khoom steel ntau ruaj thiab hnav-resistant. Tsis tas li ntawd, silicon-chromium alloy tseem tuaj yeem txhim kho cov thermal stability thiab kub tsis kam ntawm cov hlau, yog li cov hlau tuaj yeem siv tau ntev hauv qhov kub thiab txias ib puag ncig yam tsis poob kev ua haujlwm.
Hauv kev tsim cov hlau, Silicon chrome feem ntau yog siv los ua cov khoom siv ntxiv thiab ntxiv rau lub qhov cub rau smelting nrog lwm cov alloys los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm cov khoom kawg. Nyob rau hauv cov txheej txheem casting, Silicon chrome alloy kuj tuaj yeem siv los kho cov kua dej thiab cov khoom siv hlau thaum lub sij hawm casting txheej txheem, thiaj li tau txais cov khoom zoo tshaj plaws casting.
Cov txheej txheem ntau lawm ntawm Silicon chrome alloy feem ntau suav nrog hluav taws xob rauv smelting txoj kev, silicon-muaj txoj kev txo qis thiab hlau molybdenum txo txoj kev. Cov txheej txheem ntau lawm muaj qee yam cuam tshuam rau qhov zoo thiab tus nqi ntawm cov khoom, thiab qhov chaw tsim khoom tseem ceeb tseem yog Tuam Tshoj.
Silicon chrome alloy muaj ntau yam kev siv hauv kev lag luam metallurgical. Nws yog ib qho tseem ceeb ntawm cov khoom siv hlau thiab ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau thiab cov txheej txheem casting. Nws cov nyhuv hloov kho ua rau cov ntaub ntawv steel siv tau ntau dua thiab siv tau, thiab tseem muaj peev xwm ua rau kev hloov kho thev naus laus zis thiab cov khoom lag luam hauv kev lag luam steel.
Nyob rau hauv luv luv, Silicon chrome alloy yog ib qho tseem ceeb alloy khoom nrog ntau yam kev siv nyob rau hauv steel metallurgy thiab casting industries. Nws zoo li txhim kho kev ua tau zoo thiab zoo ntawm cov khoom steel, thiab pab txhim kho tag nrho cov kev sib tw thiab kev txhim kho kev muaj peev xwm ntawm kev lag luam steel.
