High Carbon Silicon Alloy
High carbon silicon, tseem hu ua silicon -carbon alloy, yog tus nqi- siv tau zoo metallurgical khoom sib txuas cov silicon thiab carbon. Nws tau dav siv hauv steelmaking thiab foundries ua deoxidizer, alloying tus neeg sawv cev, thiab carbon raiser. Ntau tus hauv kev lag luam paub lub npe tab sis tsis meej txog nws cov txiaj ntsig tiag tiag, kev qhia tshwj xeeb, thiab qhov zoo tshaj plaws - siv cov xwm txheej. Kab lus no rhuav tshem nws hauv cov lus yooj yim tshaj lij.
Kev sab laj ntawm Customized High Carbon Silicon
Core Composition & Basic nta
High carbon silicon feem ntau muaj55-70% silicon, 10-20% carbon, nrog tsawg phosphorus thiab sulfur.
Uniform muaj pes tsawg leeg ua kom ruaj khov cov tshuaj tiv thaiv hauv qhov cub.
Tsawg melting point tshaj ferrosilicon, yog li nws melts sai dua thiab ua haujlwm zoo.
Ua raws li ob qho tib si deoxidizer thiab cov khoom siv carbon hauv ib qho ntxiv.
Lub luag haujlwm tseem ceeb hauv Steelmaking & Foundry
Muaj zog deoxidation: Reacts sai nrog oxygen hauv molten hlau los ua SiO₂, txo porosity thiab inclusions; cov hlau huv huv, tsawg dua qhov tsis xws luag.
Kev kho carbon: Muab cov pa roj carbon monoxide khaws cia, txo lossis tshem tawm qhov xav tau ntawm cov recarburizers cais; zoo tagnrho rau nruab nrab-tsawg carbon steel.
Alloying nyhuv: Silicon boosts steel zog, hardness, thiab corrosion kuj.
Cov txiaj ntsig ntawm Foundry: Txhim kho molten hlau fluidity, nto tiav, thiab graphitization nyob rau hauv grey hlau thiab ductile hlau casting.
Qhov zoo tshaj li cov khoom siv niaj hnub
Kev txuag nqi: 20-40% pheej yig dua ferrosilicon lossis silicon carbide; tuaj yeem hloov ib feem ntawm ob qho tib si, txiav cov nqi raw khoom los ntawm 10-30%.
Kev ua haujlwm siab dua: Kev yaj sai dua, slag tsawg dua, thiab siab dua Si / C rov qab.
Kev txuag hluav taws xob: Exothermic cov tshuaj tiv thaiv pab tswj qhov kub thiab txias, txo lub zog thiab siv hluav taws xob.
Eco-phooj ywg: Kev siv hluav taws xob qis dua thiab rov ua dua silicon slag txo cov khib nyiab, haum rau cov hom phiaj ntsuab metallurgy.
Tej kev siv
Steelmaking: Converter (BOF), hluav taws xob arc rauv (EAF), thiab ladle refining (LF) rau kev tsim steel, rebar, structural steel, thiab cov hlau alloy.
Foundry: Grey hlau, ductile hlau, thiab dav casting los txhim kho fluidity thiab mechanical zog.
Alloy ntau lawm: Raws li cov khoom siv rau lwm yam silicon-based ferroalloys.
