Khoom Description
Silicon calcium alloy yog tsim los ntawm silicon thiab calcium, uas cov ntsiab lus ntawm silicon yog li ntawm 60-65% thiab cov ntsiab lus ntawm calcium yog 22-35%. Silicon calcium yog cov xim tsis muaj xim, tsis muaj ntxhiab thiab tsw ntxhiab, uas muaj nyob ruaj khov ntawm qhov kub thiab txias. Nws muaj hardness zoo, uas yog nyuaj tshaj li feem ntau hlau.
Silicon calcium alloy tuaj yeem siv los ua deoxidizer hauv cov txheej txheem steelmaking. Molten steel muaj qee qhov nyiaj ntawm cov pa oxygen, uas yuav cuam tshuam rau cov khoom ntawm cov hlau yog tias nws tsis raug tshem tawm hauv lub sijhawm. Calcium nyob rau hauv silicon calcium alloy tuaj yeem hnov mob chemically nrog oxygen hauv molten steel los tsim oxides (xws li CaO) insoluble hauv molten steel, yog li ua tiav lub hom phiaj ntawm deoxidation. Nyob rau tib lub sijhawm, qhov sib ntxiv ntawm silicon calcium alloy tseem tuaj yeem tshem tawm cov teeb meem impurities xws li sulfur thiab phosphorus hauv cov hlau molten, thiab ntxiv txhim kho cov hlau zoo. Silicon calcium alloy kuj tseem siv tau los ua tus neeg ua haujlwm huv rau cov hlau molten thaum lub sij hawm steelmaking. Nws tuaj yeem cuam tshuam nrog nonmetallic inclusions (xws li alumina thiab sulfide) hauv molten steel los tsim cov tebchaw uas yooj yim rau ntab thiab tshem tawm, yog li purifying molten steel thiab txhim kho cov purity thiab zoo ntawm cov hlau.
Nyob rau hauv tus txheej txheem ntawm nruam casting, silicon calcium alloy kuj siv tau los npaj nruam casting pwm flux. Nruam casting flux yog ib hom slag txheej npog ntawm cov hlau molten, uas tuaj yeem tiv thaiv molten steel los ntawm oxidized thiab polluted los ntawm huab cua, thiab tib lub sij hawm ua lub luag hauj lwm ntawm lubrication thiab tshav kub hloov. Qhov sib ntxiv ntawm silicon calcium alloy tuaj yeem txhim kho cov khoom ntawm pwm flux, xws li txo nws cov melting point thiab txhim kho nws cov stability, txhim kho cov smoothness ntawm cov nruam casting txheej txheem thiab qhov zoo ntawm billet. Hauv ib lo lus, calcium silicate yog siv dav hauv metallurgy.
