FERRO Cacacium Silicon tshwj xeeb rau kev xa tawm

FERRO Cacacium silicon (Fecasi) yog tus ternary alloy muaj cov hlau (FE), calcium (ca). Nws yog dav siv nyob rau hauv cov statmaking thiab casting kev lag luam vim nws zoo deoxidizing zoo, desulfurizing, thiab inoculating zog. Qhov no alloy ua si lub luag haujlwm tseem ceeb hauv kev txhim kho qhov zoo thiab kev ua tau ntawm cov hlau thiab cov hlau cam los ntawm kev kho cov khoom siv thiab txhim kho cov khoom siv tshuab.

Ferro Calcium silicon feem ntau muaj:

Calcium (ca): 10–30%

Silicon (si): 50–60%

Hlau (FE):Seem

Cov alloy yog tsim nyob rau hauv submerged arc rauv taws los ntawm kev txo cov silica (sio₂) thiab txiv qaub (cao) nyob rau hauv muaj hlau scrap lossis hlau ore. Lub siab-smecting txheej txheem ua kom muaj kev tsim cov homogeneous alloy nrog tswj cov ntsiab lus calcium thiab silicon.

Haib deoxidization:

Calcium thiab silicon muaj kev muaj zog rau cov pa, ua kom zoo nkauj ntawm kev tshem cov pa oxygen los ntawm Molasen Steel, yog li tiv thaiv porosity thiab txhim kho cov hlau huv.

Lub Peev Xwm Desulfurization:

Calcium reacts nrog cov leej faj los ua cov calcium sulfide (CAS), uas tau muab tshem tawm cov ntsiab lus sulfur thiab txhim kho steel ductility thiab kev nruj.

Inoculation hauv cam khwb cia hlau:

Hauv cov hlau cam ntau lawm, Fecasi txhawb nqa graphite nucleation graphite nucleation graphite nucleation graphite flakes lossis spheroidal graphite lug, uas txhim kho tshuabsab thiab kev kho tshuab thiab lub zog.

Kev Hloov Kho ntawm Tsis yog Hlau Hlau Inclusions:

Lub alloy no pab hloov kev puas tsuaj alumina (al₂o₃) suav nrog tsawg alumicine aluminium thiab txo cov hlau nplaum thiab txo cov nozzle clogging hauv nrum txuas rau hauv nrum pleb.
