Khoom Description
Ferrosilicon yog ib qho tseem ceeb deoxidizer hauv kev lag luam steel. Metallurgical coke txo tus neeg sawv cev feem ntau yog siv hauv smelting ferrosilicon, thiab steel seem yog tus tswj ntawm ferrosilicon. Nws yog dav siv nyob rau hauv steel kev lag luam, foundry kev lag luam thiab lwm yam industrial ntau lawm. Silicon muaj ob allotropes: amorphous thiab crystalline. Crystalline silicon yog hlau grey, thaum amorphous silicon yog dub. Silicon yog dav faib nyob rau hauv cov xwm, muaj li ntawm 27.6% nyob rau hauv lub ntiaj teb crust. Nws cov khoom siv tshuaj lom neeg kuj tseem ua haujlwm. Nws yog insoluble hauv dej, nitric acid thiab hydrochloric acid, tab sis soluble nyob rau hauv hydrofluoric acid thiab lye, thiab nws yog feem ntau siv los ua alloys xws li ferrosilicon thiab silicon steel.
Silicon alloy yog siv los txo tus neeg sawv cev hauv kev lag luam ferroalloy los tsim cov pa roj carbon tsawg ferroalloy. Qhov sib ntxiv ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem siv los ua ib qho inoculant rau cov hlau ductile, thiab tuaj yeem tiv thaiv kev tsim cov carbides, txhawb cov nag lossis daus thiab spheroidization ntawm graphite thiab txhim kho cov khoom ntawm cam khwb cia hlau. Ntxiv ib qho nyiaj ntawm silicon rau hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, txhim kho cov hlau nplaum permeability ntawm hlau thiab txo cov hysteresis poob ntawm transformer hlau. Kev lag luam steelmaking, foundry kev lag luam thiab ferroalloy kev lag luam yog cov neeg siv loj tshaj plaws ntawm ferrosilicon.
Txawm li cas los xij, vim tias ferrosilicon muaj cov phosphorus hlau me me, xws li calcium phosphide, thaum nws ntub dej, nws tuaj yeem tso cov phosphine, uas ua rau qhov chaw kaw tag nrho ntawm cov pa phem thiab ua rau muaj kev phom sij hauv lub tsev thiab cov neeg nyob ib puag ncig thaum lub sij hawm. kev thauj mus los. Phosphine lom tuaj yeem ua rau tuag taus thaum mob hnyav.
Cim npe nrov: zoo ferrosilicon nyob rau hauv Tuam Tshoj, Tuam Tshoj zoo ferrosilicon nyob rau hauv Tuam Tshoj manufacturers, lwm tus neeg, Hoobkas
