Ferro Silicon Calcium (tseem hu uaCalcium Siliconlos yog CaSi) yog ib qho kev ua tau zoo ntawm - cov khoom sib xyaw ua ke, ua kom zoo zoo los ua lub zog deoxidizer, desulfurizer, thiab kev hloov pauv hauv kev tsim cov hlau huv thiab siab - zoo cam khwb cia hlau. Los ntawm kev sib koom ua ke lub zog deoxidation muaj zog ntawm silicon nrog qhov tshwj xeeb suav nrog- hloov kho cov peev txheej ntawm calcium, cov hlau no muaj kev sib koom ua ke rau kev txhim kho steel purity, txhim kho castability, thiab boosting the mechanical performance of the final products. Muaj nyob rau hauv ntau qib (piv txwv li, Ca31Si60, Ca28Si60), nws yog ib qho tseem ceeb rau cov neeg siv hlau niaj hnub no txhawm rau ua kom tau raws li cov qauv nruj.

Calcium silicon yog ib qho hlau alloy uas muaj calcium (Ca) thiab silicon (Si), uas feem ntau siv hauv kev lag luam xws li steel smelting thiab casting. Nws cov khoom tseem ceeb yog calcium thiab silicon, feem ntau muaj ib feem ntawm calcium thiab silicon, nrog rau cov ntsiab lus calcium feem ntau ntawm 20% -40% thiab cov ntsiab lus silicon ntawm 30% -70%.

1. Steel Refining: Deoxidation, Desulfurization & Inclusion Engineering

Hauv kev tsim steel theem nrab (piv txwv li, hauv LF lossis RH cov hlab ntsha), Ferro Silicon Calcium plays lub luag haujlwm ntau yam:

Ua kom muaj txiaj ntsig Deoxidation:

Silicon muab thawj deoxidation, thaum calcium ntxiv reacts nrog yaj oxygen, tsim oxides ruaj khov uas ntab mus rau hauv slag, ua rau cov hlau huv.

Muaj zog Desulfurization:

Calcium muaj affinity siab rau sulfur. Nws reacts tsim calcium sulfide (CaS), uas yog zoo tshem tawm mus rau hauv lub slag, ho txo cov sulfur ntsiab lus. Qhov no yog ib qho tseem ceeb rau kev txhim kho steel lub toughness, ductility, thiab kuj rau hydrogen-induced cracking (HIC).

Inclusion Morphology Control (Nws Lub luag haujlwm tseem ceeb tshaj plaws):

Hauv aluminium-tua steels, tawv, brittle alumina (Al₂O₃) suav nrog tuaj yeem txo qhov qaug zog lub neej. Calcium los ntawm cov alloy hloov cov no mus rau hauv tsis tshua muaj teeb meem, kua calcium aluminates nyob twj ywm spherical thiab me me, dramatically txhim kho cov hlau cov khoom thiab machinability.

2. Kev lag luam Foundry: Siab -Kev Ua Haujlwm Tsis Zoo rau Cast Irons

Hauv kev tsim cov ductile (nodular) thiab grey cam khwb cia hlau, Silicon Calcium yog ib qho zoo heev inoculant:

Graphite Nucleation:

Nws txhawb kev tsim ntawm ntau graphite nuclei thaum lub sij hawm solidification. Qhov no ua rau muaj kev sib faib ntawm nplua, Hom A graphite hauv cov hlau grey thiab cov nodule siab suav hauv cov hlau hlau.

Txias Txias:

Nws ua tau zoo txo cov kev nyiam rau kev tsim cov tawv tawv, nkig carbide cov qauv (txias) ntawm cov npoo casting, txhim kho machinability thiab txo cov cuab yeej hnav.

Khoom Txhim Kho:

Los ntawm kev ua kom zoo dua cov qauv graphite, nws txhim kho cov hlau cam khwb cia lub zog tensile, hnav tsis kam, thiab tag nrho cov tshuab ua haujlwm.

3. Alloying Agent rau Tshwj Xeeb Steels

Hauv kev tsim cov khoom siab- alloys lossis cov hlau tshwj xeeb (xws li, cua sov- cov hlau tsis muaj zog, qee cov qib stainless), Ferro Calcium Silicon tuaj yeem siv los ua cov alloying ntxiv los qhia txog cov tshuaj calcium thiab silicon rau kev txhim kho cov cuab yeej tshwj xeeb, xws li kev txhim kho siab - kub lub zog lossis oxidation tsis kam.
