High Carbon Ferro Silicon HCFeSi

High carbon ferro silicon (HCFeSi) yog ib qho hlau uas muaj hlau, silicon, thiab carbon, nrog cov ntsiab lus carbon feem ntau li ntawm 2 feem pua ​​​​rau 8 feem pua. Cov ntsiab lus silicon feem ntau yog nyob nruab nrab ntawm 65 feem pua ​​​​mus rau 70 feem pua ​​​​, thaum seem seem yog tsim los ntawm lwm cov khoom xws li txhuas, calcium, thiab manganese.

HCFeSi feem ntau yog siv los ua deoxidizer thiab tus neeg sawv cev alloying hauv kev tsim cov hlau. Nws cov ntsiab lus carbon siab tso cai rau nws kom tshem tawm cov pa oxygen los ntawm cov hlau molten, uas yuav pab txhim kho cov hlau cov khoom, xws li lub zog thiab hardness. Cov ntsiab lus silicon pab tswj cov nplej loj ntawm cov hlau, uas tuaj yeem cuam tshuam nws cov khoom kawg.

Tsis tas li ntawd, HCFeSi tuaj yeem siv rau hauv kev tsim cov hlau cam khwb cia, qhov twg nws tuaj yeem pab txo qhov tsim ntawm graphite thiab txhim kho qhov hnav tsis kam ntawm cov cam khwb cia hlau. Nws kuj tseem siv rau hauv kev tsim cov hlau tsis tshua muaj hlau thiab stainless hlau los txhim kho lawv cov machinability thiab corrosion kuj.

HCFeSi yog cov khoom tseem ceeb hauv kev lag luam steel, vim nws tuaj yeem pab txo cov nqi tsim khoom thiab txhim kho qhov zoo ntawm cov khoom kawg. Nws kuj yog feem ntau siv nyob rau hauv foundries thiab steel mills los hloov kho rau cov muaj pes tsawg leeg ntawm cov hlau thaum lub sij hawm ntau lawm.
