Silicon Calcium Nrog Zoo Zoo

Cov ntsiab lus calcium ntawm silicon calcium alloy feem ntau yog nruab nrab ntawm 22% thiab 35%, thiab cov ntsiab lus silicon yog nyob nruab nrab ntawm 60% thiab 65%. Raws li YB 525-65 tus qauv, cov ntsiab lus calcium ntawm silicon calcium alloy tsis tsawg dua 31%, 28% thiab 24% feem. Silicon calcium alloy muaj lub peev xwm txo qis thiab yog qhov zoo tshaj plaws deoxidizer thiab desulfurizer. • Kev tsim cov silicon calcium alloy feem ntau yog siv cov txheej txheem ntawm carbon txo cov calcium oxide (lime) thiab silica. Rau silicon calcium alloy nrog qis cov ntsiab lus calcium, silicon thermal method yog siv.

Calcium thiab silicon nyob rau hauv silicon-calcium alloy muaj zog affinity nrog oxygen, tshwj xeeb tshaj yog calcium, uas muaj zog affinity tsis tsuas yog nrog oxygen, tab sis kuj nrog sulfur thiab nitrogen. Yog li ntawd, silicon-calcium alloy yog ib qho zoo tagnrho deoxidizer. Hauv cov txheej txheem steelmaking, silicon-calcium alloy tuaj yeem hnov ​​​​mob nrog oxides hauv cov hlau molten los tsim cov calcium oxide thiab koom nrog hauv kev tsim cov hlau oxide complexes, yog li txo cov pa oxygen hauv cov hlau molten thiab txhim kho cov purity thiab lub zog ntawm cov hlau. Silicon thiab calcium nyob rau hauv silicon-calcium alloy muaj zog txo cov khoom thiab tuaj yeem hnov ​​​​mob nrog sulfides hauv molten steel los tsim cov pa roj hydrogen sulfide (H2S), kom cov sulfur hauv molten steel yog txo thiab volatilized, ua tiav lub hom phiaj ntawm desulfurization thiab txhim kho cov steel zoo. Silicon thiab calcium hauv silicon-calcium alloy yog ob qho tib si txo cov neeg ua haujlwm thiab cov ntsiab lus alloying. Ntxiv silicon-calcium alloy rau molten steel tuaj yeem kho cov ntsiab lus tsis yog hlau hauv molten steel thiab ua rau muaj kev hloov pauv hauv cov ntsiab lus alloying hauv cov hlau. Piv txwv li, silicon-calcium alloy nrog cov ntsiab lus siab ntawm silicon tuaj yeem siv los ua kom cov ntsiab lus silicon thiab cov ntsiab lus ntawm cov khoom siv silicon alloying, yog li txhim kho cov kev ua tau zoo ntawm cov hlau thiab yoog raws cov kev thov sib txawv.

Silicon calcium alloy tuaj yeem txhim kho lub cev thiab tshuaj lom neeg ntawm cov hlau, thiab muaj txiaj ntsig zoo los txhim kho cov txheej txheem ntawm oxide thiab sulfide suav nrog hauv cov hlau tiav thiab cov castings. Qhov sib ntxiv ntawm silicon calcium alloy tuaj yeem txhim kho cov yas, cuam tshuam toughness thiab fluidity ntawm hlau, yog li txhim kho tag nrho cov kev ua tau zoo ntawm cov hlau. Silicon calcium alloy kuj tseem siv tau los ua ib qho inoculant rau cam khwb cia hlau, uas tuaj yeem txhim kho lub zog thiab hardness ntawm cam khwb cia hlau los ntawm refining cov nplej. Silicon calcium alloy kuj tsim nyog ua tus neeg sawv cev ua kom sov hauv converter steelmaking Rhiav, uas pab txhim kho steelmaking efficiency.

Hauv cov ntsiab lus, silicon-calcium alloy plays ntau lub luag haujlwm tseem ceeb hauv metallurgical teb, xws li deoxidation, desulfurization, alloy hloov, thiab txhim kho cov khoom steel. Nws yog ib qho indispensable additive nyob rau hauv cov txheej txheem steel smelting.
