Dab tsi yog Silicon-Carbon Alloy

Silicon-carbon alloy yog cov khoom siv ua haujlwm siab- cov khoom sib xyaw uas nws cov ntsiab lus tseem ceeb muaj silicon (65% ~ 75%) thiab carbon (15% ~ 25%). Nws yog tsim los ntawm smelting quartz, coke thiab hlau filings nyob rau hauv ib tug siab -kub hluav taws xob rauv ntawm 1800 ~ 2000 degree.

Cov alloy no txawj sib txuas ua ke zoo ntawm silicon thiab carbon, muaj ob qho tib si siab -kub tsis kam ntawm silicon thiab hluav taws xob conductivity ntawm carbon. Nws yog cov khoom tshwj xeeb uas ua rau nws tseem ceeb heev hauv ntau yam kev siv.

Cov khoom nyoos

Peb cov ntaub ntawv tseem ceeb rau kev tsim cov silicon- carbon alloys yog quartz, coke thiab hlau filings. Cov ntaub ntawv nyoos no tsis yog siv ncaj qha, tab sis yuav tsum tau ua raws li qhov sib piv thiab kev kho mob los npaj lawv rau cov txheej txheem smelting tom ntej thiab kom ntseeg tau qhov zoo ntawm cov khoom kawg.

Cov txheej txheem ntau lawm

Kev smelting ntawm silicon- carbon alloys nyob ntawm siab -kub hluav taws xob arc rauv, uas yuav tsum ncav cuag qhov kub ntawm 1,800 txog 2,000 degrees Celsius. Nyob rau hauv ib puag ncig kub zoo li no, cov khoom siv raw yuav dhau los ua cov tshuaj lom neeg ua haujlwm nyuaj, thiab dhau los ntawm cov txheej txheem ntawm kev hloov pauv, silicon - carbon alloy yog thaum kawg tsim.

Siab zog ceev

Hauv thaj teb ntawm lithium-Ion roj teeb, silicon-carbon alloys qhia tau zoo heev rau daim ntawv thov. Lub peev xwm theoretical ntawm silicon yog hais txog 4200mAh / g, uas yog ntau dua li 372mAh / g ntawm cov khoom siv graphite anode ib txwm muaj, thiab yog li nws tuaj yeem ua kom lub zog ntom ntom ntawm cov roj teeb.

Lub neej voj voog ntev

Silicon yog ib qho yooj yim rau ntim expansion thaum lub sij hawm them thiab tawm, uas yog zoo mitigated los ntawm silicon -carbon alloys. Cov yam ntxwv no ua rau lub roj teeb lub neej ua haujlwm txuas ntxiv, muab kev lees paub ntev - siv sijhawm ntev.

Hluav taws xob thiab Thermal conductivity

Silicon-carbon alloys muaj hluav taws xob zoo heev thiab thermal conductivity. Qhov no tsis yog tsuas yog txhim kho kev them nyiaj ceev ntawm lub roj teeb, tso cai rau cov neeg siv txo lub sijhawm tos, tab sis kuj tseem txhim kho kev nyab xeeb ntawm lub roj teeb thiab txo qhov kev pheej hmoo ntawm kev siv.

Kev tsim kho kom zoo

Los ntawm kev ua kom zoo dua qhov piv thiab cov qauv ntawm silicon thiab carbon, cov kws tshawb fawb tuaj yeem tsim cov khoom siv roj teeb anode nrog kev ua tau zoo dua thiab ruaj khov dua, ntxiv dag zog rau roj teeb technology.

Qhov zoo ntawm Deoxidation

Silicon-carbon alloy muaj cov khoom siv silicon, tom qab ntxiv silicon-carbon alloy hauv cov txheej txheem steel, cov khoom silicon yuav hnov ​​​​mob nrog oxygen kom paub qhov deoxidation ntawm hlau. Cov txheej txheem no tuaj yeem txhim kho qhov hardness thiab zoo ntawm cov hlau.

Nyob rau tib lub sijhawm, vim muaj kev sib raug zoo ntawm silicon thiab oxygen, hlau yuav tsis txaws tom qab ntxiv silicon -carbon alloy, uas lav kev nyab xeeb ntawm cov txheej txheem steelmaking.

Qhov zoo ntawm slag collection

Muab qee qhov kev faib ua feem ntawm silicon-carbon alloy rau hauv cov dej steel tuaj yeem txhawb nqa cov agglomeration sai ntawm oxides uas tsim nyob rau hauv cov txheej txheem steelmaking. Nyob rau hauv txoj kev no, nws yooj yim rau kev lim dej thiab ua rau cov hlau molten purer.

Thiab cov hlau ntshiab tuaj yeem ua kom qhov ntom ntom thiab tawv ntawm cov hlau, txhim kho tag nrho cov hlau zoo.

Qhov zoo ntawm qhov kub ntawm qhov cub

Silicon{0}} carbonalloy yog qhov kub zoo heev - cov khoom siv tiv taus. Ntxiv silicon-carbon alloy rau cov txheej txheem steelmaking tuaj yeem ua rau kom kub kub. Qhov kev nce hauv qhov kub ntawm qhov cub yuav pab ua kom lub zog hloov pauv ntawm ferroalloys, thiab tib lub sijhawm ua kom cov tshuaj tiv thaiv ntawm cov hlau thiab lwm cov ntsiab lus, txhim kho kev ua haujlwm ntawm steelmaking.

Tus nqi -txuag qhov zoo

Niaj hnub no, tus nqi ntawm cov ntaub ntawv ferroalloy tseem siab, thaum silicon carbon alloy, raws li hom tshiab ntawm metallurgical khoom, tsis tshua kim dua li cov khoom siv hlau. Nws tuaj yeem hloov cov khoom siv hlau kim xws li ferrosilicon nrog cov txiaj ntsig zoo.

Cov yam ntxwv no tso cai rau ntau tus neeg tsim khoom kom txuag tau cov nqi thiab yog li nce cov txiaj ntsig.

Silicon-carbon alloys yog siab-carbon elemental ferrous alloys nrog cov ntsiab lus carbon ntawm 15 - 30 thiab cov ntsiab lus silicon ntawm 55% - 65% ntawm cov khoom ferrosilicon.

Qhov tseem ceeb tshaj, tus nqi ntawm silicon{0}} carbon alloys qis dua li ntawm ferrosilicon. Cov txheej txheem tsim khoom txo cov nqi khoom, yog li yog tias koj tsis txhob txwm xav txog cov ntsiab lus carbon tab sis tsuas yog tsom mus rau cov ntsiab lus ntawm silicon, silicon -carbon alloys yog undoubtedly ib qho zoo tagnrho lwm txoj rau ferrosilicon.

Block form (10 - 50mm)

Silicon- carbon alloys nyob rau hauv bulk daim ntawv yog tsuas yog siv rau steel deoxidizing thiab casting carbon li. Hauv steel deoxidation, nws tuaj yeem txhim kho qhov purity ntawm hlau; hauv casting carbonization, nws tuaj yeem txhim kho qhov hnav tsis kam ntawm castings thiab txhim kho kev ua haujlwm ntawm castings.

Daim ntawv hmoov (100 - 200 mesh)

Silicon-carbon alloy nyob rau hauv hmoov daim ntawv tuaj yeem siv los ua ke silicon carbide, thiab tuaj yeem siv los ua cov khoom siv roj teeb tshiab. Thaum siv cov khoom siv roj teeb tshiab, nws tuaj yeem txhim kho cov kev ua haujlwm ntawm lub roj teeb, pab txhim kho kev ua haujlwm ntawm cov roj teeb hluav taws xob tshiab.

Hauv cov ntsiab lus, nrog nws qhov tshwj xeeb muaj pes tsawg leeg thiab cov txheej txheem tsim khoom, silicon - carbon alloy muaj ntau yam zoo heev thiab cov txiaj ntsig tseem ceeb, thiab muaj ntau yam kev siv tseem ceeb hauv steelmaking, casting, tshiab zog roj teeb thiab lwm yam.
