Chromium silicon alloyyog ib qho kev sib xyaw ferro alloy uas ua lub luag haujlwm tseem ceeb hauv cov hlau thiab lwm yam kev lag luam. chromium silicon alloy yog ib qho hlau uas muaj silicon, chromium, hlau thiab ib qho me me ntawm lwm cov khoom ua los ntawm hluav taws xob rauv smelting nrog chromium ore, silica, coke thiab lwm yam khoom siv raw li cov ntaub ntawv tseem ceeb. Cov khoom tseem ceeb yog silicon (Si), chromium (Cr) thiab hlau (Fe). Feem ntau chromium silicon alloys muaj 30% - 40% silicon, 25% - 35% chromium, thiab tus so yog hlau thiab me me ntawm impurities xws li carbon, phosphorus, sulfur, thiab lwm yam. Cov ntsiab lus ntawm txhua tus. cov khoom hauv chromium silicon alloys rau ntau lub hom phiaj yuav raug kho.

Cov chaw thov
Steelmaking kev lag luam
Raws li ib tug deoxidizer, silicon thiab chromium nyob rau hauv chromium silicon alloy reacts nrog oxygen nyob rau hauv molten hlau los tsim silicon dioxide thiab chromium oxide, txo cov pa cov ntsiab lus nyob rau hauv steel, tiv thaiv tsis xws luag xws li pores thiab looseness los ntawm oxygen, thiab txhim kho lub purity thiab zoo ntawm cov hlau. hlau. Nyob rau tib lub sijhawm, nws kuj yog ib qho tseem ceeb alloying tus neeg sawv cev. Chromium tuaj yeem txhim kho lub hardenability, hnav tsis kam, corrosion kuj thiab kub siab zog ntawm cov hlau, thiab silicon tuaj yeem ua rau lub zog, hardness thiab elastic txwv ntawm cov hlau. Yog li ntawd, nws yog dav siv nyob rau hauv zus tau tej cov alloy steels xws li stainless hlau, tshav kub-resistant steel, thiab pob bearing steel.
Casting kev lag luam
Ntxiv chromium silicon alloy thaum lub sij hawm casting txheej txheem tuaj yeem kho cov nplej, txhim kho cov txheej txheem ntawm cov casting, thiab txhim kho lub zog, hardness thiab hnav tsis kam ntawm casting. Nws yog feem ntau siv los tsim cov khoom hnav-resistant castings thiab high-strength castings, xws li hauv ob sab phlu ntawm mining machinery, rauj ntawm crusher, thiab cov khoom tseem ceeb ntawm lub tsheb cav, thiab lwm yam, kom ntev kev pab cuam lub neej ntawm cov castings.
Lwm yam teb
Hauv kev tsim cov ferroalloys, chromium silicon alloy tuaj yeem siv los ua cov khoom siv raw rau kev tsim cov ferroalloys xws linruab nrab-carbon ferrochromethiabtsawg-carbon ferrochrome. Hauv kev tsim cov khoom siv vuam, ntxiv chromium silicon alloy tuaj yeem hloov pauv cov ntsiab lus ntawm cov hlau vuam, txhim kho lub zog, toughness thiab corrosion kuj ntawm cov vuam, thiab xyuas kom cov vuam zoo. Nws yog tshwj xeeb tshaj yog haum rau vuam ntawm tshwj xeeb steels xws li stainless hlau.
