Superior Zoo Steelmaking Casting Hlau FeSi / Ferro silicon / Ferro Silicon 75/72/65 Ferro Silicon

Ferro silicon 75 yog dav siv nyob rau hauv steel ua thiab casting. Hauv cov txheej txheem steelmaking, cov hlau yuav tsum tau oxygenated kom ua tiav qhov zoo tagnrho qhov kub thiab txias ib puag ncig, thiab cov pa ntau dhau ntawm cov theem tom ntej yuav tsim ntau cov oxides hauv cov hlau, uas cuam tshuam rau cov hlau zoo. Nyob rau tib lub sijhawm, ferro silicon 75 kuj tseem tuaj yeem txhawb nqa lub zog ntawm cov hlau, txhim kho tus nqi nqus, txo cov nqi tsim khoom thiab nce cov txiaj ntsig ntawm cov hlau zeb.

Ferro silicon 75 kuj tseem siv tau los ua lwm txoj hauv kev inoculants hauv casting los txhim kho qhov tsim thiab nce cov eutectic pellets. Qhov sib ntxiv ntawm ferro silicon 75 hauv kev tsim cov hlau ductile tuaj yeem tiv thaiv kev tsim cov carbides hauv cov hlau thiab txhawb cov nag lossis daus thiab spheroidization ntawm graphite. Nws tuaj yeem txhim kho qhov fluidity ntawm cov hlau, yog li tiv thaiv clogging ntawm lub qhov hluav taws xob thiab txo qhov nyiam ntawm lub qhov ncauj dawb ntawm lub casting.

Ferrosilicon muaj pes tsawg leeg lub rooj.

Cov ntsiab lus

Ferrosilicon yog ib hom ferroalloy uas yog tsim los ntawm kev txo cov silica los yog xuab zeb nrog coke nyob rau hauv muaj hlau. Tej qhov chaw ntawm hlau yog seem hlau los yog milscale. Ferrosilicons nrog silicon cov ntsiab lus txog li 15% yog tsim nyob rau hauv blast furnaces lined nrog acid hluav taws cib. Ferrosilicons nrog ntau dua silicon cov ntsiab lus yog tsim nyob rau hauv hluav taws xob arc furnaces.Cov formulations ib txwm nyob rau hauv lub lag luam yog ferrosilicons nrog 60-75% silicon, cov seem yog hlau, muaj li ntawm 2% muaj lwm yam xws li txhuas thiab calcium, ib tug overabundance ntawm silica yog siv los tiv thaiv kev tsim ntawm silicon carbide.
