Silicon Carbon Alloy Briquettes

Silicon carbon alloy briquettes yog spherical composite khoom tsim los ntawm kev tshawb fawb sib xyaw thiab compressing silicon thiab carbon, ob lub ntsiab lus tseem ceeb. These balls feature uniform density and typically measure 10–50 mm in diameter, ensuring convenient handling. Thaum lub sij hawm steelmaking, cov pa roj carbon thiab silicon nyob rau hauv silicon - cov pa roj carbon monoxide sai sai nrog oxygen nyob rau hauv cov hlau molten, yooj yim diffusion deoxidation. Lub unoxidized feem ncaj qha dissolves rau hauv cov hlau molten, ua tiav ob qho txiaj ntsig ntawm deoxidation thiab carbon enrichment. Lawv tau siv dav hauv kev tsim cov khoom qis- alloy structural steel, carbon steel, thiab bearing steel, thiab tseem ua tus neeg sawv cev txo qis hauv kev lag luam ferroalloy.

① Deoxidation

Cov silicon hauv silicon- cov pa roj carbon alloy cov khoom muaj cov tshuaj lom neeg muaj zog nrog cov pa oxygen, ua kom muaj txiaj ntsig zoo nrog cov pa oxygen hauv cov hlau molten kom ua tiav cov nag lossis daus deoxidation thiab diffusion deoxidation. Qhov no txo ​​qis cov pa oxygen hauv cov hlau molten, txo qis cov oxide inclusions, txhim kho steel purity, thiab ua kom cov khoom zoo.

② Silicon thiab Carbon Enhancement

Silicon thiab carbon tsis noj nyob rau hauv cov tshuaj tiv thaiv deoxidation yaj mus rau hauv cov hlau molten, ua rau nws cov silicon thiab carbon cov ntsiab lus kom tau raws li cov kev cai muaj pes tsawg leeg ntawm cov qib steel sib txawv. Qhov no kho lub zog, hardness, toughness, thiab lwm yam khoom ntawm cov hlau thaum txhim kho tus nqi rov qab ntawm cov ntsiab lus alloying thiab txo cov kev noj cov khoom siv alloy.

③ Thaum tshav kub kub tsim thiab rwb thaiv tsev

Silicon-cov pa roj carbon alloy cov khoom tso tawm cov cua kub ntau thaum combusted ntawm qhov kub thiab txias, ua haujlwm ua cov cua sov kom ua kom cov hlau kub kub thiab ua kom lub sij hawm luv luv. Tshwj xeeb tshaj yog thaum lub sij hawm thawj theem ntawm converter smelting thaum tshav kub tsis txaus, lawv leeb slag tsim, txhim kho slag fluidity, thiab txo lub zog noj.

④ Txhim kho Molten Steel Fluidity

Tsim nyog tus nqi ntawm silicon thiab carbon txo qhov nro ntawm cov hlau molten, txhim kho nws cov fluidity. Qhov no ua rau ntau qhov sib txawv ntawm cov pwm thaum lub sij hawm casting, txo qhov tsis xws luag, thiab txhim kho qhov zoo ntawm casting.

⑤ Hloov cov khoom siv sib xyaw ua ke

Silicon-carbon alloy npas tuaj yeem hloov cov khoom siv ib txwm siv xws li ferrosilicon, silicon carbide, thiab carbon additives. Qhov no txo ​​cov nqi tsim khoom, txo qis kev cia siab ntawm cov peev txheej tsawg, ua kom yooj yim rau cov txheej txheem smelting, thiab boosts ntau lawm efficiency.

⑥ Refining Grain Structure

Ntxiv silicon-cov pa roj carbon alloy cov khoom rau cov hlau molten pab ua kom zoo dua cov qauv ntawm cov nplej, txhim kho cov khoom siv zoo xws li lub zog, tawv, thiab hnav tsis kam, yog li txuas ntxiv lub neej kev pab cuam ntawm cov khoom steel.

⑦ Spheroidizing kho rau cov hlau nrum

Hauv kev tsim cov hlau cam khwb cia, silicon- cov pa roj carbon alloy cov khoom ua haujlwm ua inoculants rau ductile hlau, txhawb nqa graphite spheroidization thaum inhibiting carbide tsim. Qhov no txhim kho microstructure thiab cov khoom ntawm cov hlau cam khwb cia, txhim kho nws cov toughness thiab lub zog.

Silicon-carbon alloy balls zoo txhim kho metallurgical ntau lawm efficiency thiab cov khoom zoo los ntawm deoxidation, silicon/carbon enrichment, tsim tshav kub, thiab rwb thaiv tsev zog, thaum tib lub sij hawm txo nqi. Lawv ua cov khoom siv tseem ceeb hauv kev lag luam metallurgical niaj hnub.
