Kev lag luam Foundry: tus yuam sij rau kev txhim kho casting zoo
Hauv kev lag luam foundry, silicon calcium feem ntau yog siv los ua ib qho inoculant thiab spheroidizer. Nyob rau hauv tus txheej txheem ntawm cam khwb cia hlau ntau lawm, morphology thiab tis ntawm graphite muaj ib tug txiav txim siab ntawm kev ua tau zoo ntawm castings. Silicon calcium tuaj yeem txhawb nqa graphitization, txo qhov nyiam ntawm cov hlau cam khwb cia dawb, thiab tso cai rau graphite kom muaj nyob rau hauv castings hauv ntau daim ntawv zoo tshaj plaws thiab kev faib tawm. Taking the production of automobile engine cylinder block as an example, after adding silicon calcium inoculant, the cylinder block has a more uniform and dense structure, and the strength and wear resistance are greatly improved, which effectively extends the service life of the engine. Nyob rau tib lub sijhawm, kev siv calcium silicon spheroidizer tuaj yeem spheroidize cov graphite hauv cam khwb cia hlau, txhim kho qhov toughness thiab plasticity ntawm cam khwb cia hlau, thiab tso cai rau cov castings tiv taus ntau dua loads. Nws yog dav siv hauv kev tsim khoom ntawm ntau yam khoom siv kho tshuab, yeeb nkab fittings, thiab lwm yam
Kev lag luam Ferroalloy: lub hauv paus ntawm ntau- cov khoom siv hlau alloy
Hauv kev lag luam ferroalloy, calcium silicon yog cov khoom siv tseem ceeb rau kev tsim khoom ntawm ntau lwm cov khoom ferroalloy. CaSi tuaj yeem ua ke nrog cov ntsiab lus xws li barium thiab txhuas los tsim ntau yam -cov khoom sib xyaw xws lisilicon calcium bariumthiab silicon calcium aluminium. Cov ntau- cov khoom sib xyaw ua ke no muaj ntau qhov nyuaj thiab zoo heev thiab tuaj yeem ua tau raws li cov kev xav tau tshwj xeeb ntawm cov hlau tshwj xeeb. Thaum ua tau siab - lub zog alloy steel, qhov sib ntxiv ntawm SiBaCa alloy tuaj yeem txhim kho kev ua haujlwm zoo thiab ua haujlwm kub ntawm cov hlau, txhim kho kev tsim khoom thiab txo cov nqi tsim khoom. Raws li cov khoom siv raw yooj yim, silicon-calcium muab qhov ua tau rau kev lag luam ferroalloy los txhim kho ntau dua -kev ua tau zoo thiab ntau yam khoom siv alloy. cov
Tsis yog -ferrous hlau kev lag luam: additives los txhim kho kev ua tau zoo alloy
Hauv kev ua haujlwm ntawm cov hlau tsis yog-ferrous hlau, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov txhuas thiab txhuas alloys, silicon-calcium kuj muaj cov ntawv thov tseem ceeb. Qhov kev ua tau zoo ntawm aluminium alloys muaj kev cuam tshuam zoo heev los ntawm lawv cov muaj pes tsawg leeg thiab lub koom haum. Qhov tsim nyog ntxiv ntawm silicon-calcium raws li ib qho ntxiv tuaj yeem ua kom zoo dua cov qauv ntawm aluminium alloys thiab txhim kho lub zog, hardness thiab kub tsis kam ntawm aluminium alloys. Nyob rau hauv siab -kev ua tau zoo aluminium alloy cov ntaub ntawv siv nyob rau hauv aerospace teb, qhov tsim nyog ntxiv ntawm silicon-calcium tuaj yeem ua kom cov hlau ua kom muaj cov khoom siv kho tshuab zoo nyob rau hauv qhov kub thiab txias, ua tau raws li qhov xav tau ntawm cov khoom siv rau aviation cav Cheebtsam, aircraft structural qhov chaw, thiab lwm yam., thiab pab cov non-ferrous hlau kev lag luam tsim cov khoom uas muaj kev ua tau zoo dua. cov
Kev lag luam tshuaj: ib qho tseem ceeb txhawb rau cov tshuaj tiv thaiv catalytic
Hauv kev lag luam tshuaj, calcium silicon tuaj yeem siv los ua tus nqa khoom lossis ntxiv rau cov tshuaj catalysts. Nws muaj ib tug tshwj xeeb lub cev qauv thiab ib tug tej yam tshuaj stability, uas muaj peev xwm muab ib tug loj cheeb tsam ntawm lub catalyst, ua rau lub active Cheebtsam sib npaug zos rau dispersed, yog li txhim kho cov kev ua si thiab stability ntawm catalyst.
