Silicon Carbon Balls: Reshaping Steelmaking Efficiency Nrog Tus Nqi -Txuag & Tsawg-Carbon Zoo

Silicon carbide spheres muaj ntau yam haujlwm xws li cua sov, deoxidation, thiab carbonization, thiab yog tus nqi pheej yig - siv tau los tsim.

Cov khoom no yog cov khoom pelletized ua los ntawm silicon, silicon dioxide, thiab carbon. Nws tuaj yeem hloov qee yam ntawm ferrosilicon thiab carbonizing cov neeg ua haujlwm, tso cai rau cov cua sov, deoxidation, thiab carbonization ua tiav hauv ib kauj ruam. Thaum ntxiv rau cov hlau molten, nws tsis ua rau tshuab- tawm, ua tsis muaj nplaim taws, thiab muaj cov khoom siv raw khoom siab. Nws txhim kho tau zoo raws li cov teeb meem ntawm kev hlawv- tawm thiab ib puag ncig muaj kuab paug cuam tshuam nrog cov txheej txheem ib txwm siv siv ntau cov hmoov deoxidizers thiab cov tshuaj carbonizing. Vim lawv lub ntiajteb txawj nqus, cov silicon carbide spheres tog rau hauv cov hlau molten thiab maj mam nce hauv qab ntawm lub cub tawg, tsim cov pa roj carbon monoxide, uas ua rau cov hlau molten thiab txhim kho steel zoo. Nyob rau tib lub sijhawm, kev tsim cov silicon carbide spheres ua rau kev siv cov peev txheej loj ntawm kev lag luam pov tseg, tig cov khoom pov tseg rau hauv cov khoom muaj nqis thiab txo cov nqi ntau lawm steel.

Kev siv tseem ceeb thiab tus nqi
Silicon carbide npas yog siv feem ntau hauv cov txheej txheem diffusion deoxidation thaum lub sij hawm smelting ntawm cov pa roj carbon zoo tib yam. Lawv txo lub sij hawm deoxidation, txuag lub zog, thiab tus nqi pheej yig. Qhov no txhim kho steelmaking efficiency, txo cov khoom siv raw, txo cov pa phem ib puag ncig, thiab txhim kho kev ua haujlwm. Tsis tas li ntawd, lawv cov pa roj carbon - txhim kho cov nyhuv yog qhov tseem ceeb rau kev txhim kho tag nrho kev ua haujlwm ntawm hluav taws xob arc rauv steelmaking.

Raws li ib yam tshiab ntawm alloy rau converters, silicon carbide npas yuav hloov ferrosilicon, silicon carbide, thiab carbon enhancers, txo tus nqi ntawm deoxidizer siv. Lawv tsim nyog rau deoxidation alloying txheej txheem hauv converter smelting. Kev siv cov khoom no ua rau kev ua haujlwm ruaj khov; Cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab kev tswj hwm sab hauv ntawm cov hlau tsim tau zoo dua li cov txheej txheem ib txwm muaj. Nws tuaj yeem ua kom zoo dua steel zoo, txhim kho cov khoom zoo thiab kev ua tau zoo, txo cov nqi ntawm cov khoom siv raw khoom ntxiv, txo cov nqi steelmaking, thiab nce nyiaj txiag kev lag luam rau cov lag luam.

Keeb kwm
Tau ntev, hom alloys siv nyob rau hauv converter smelting tsis tau zoo kho, uas ua rau ib tug kuj yooj yim qauv ntawm tsoos alloy ntau yam. Piv txwv li, Q195 thiab Q235 steel qib siv cov txheej txheem smelting ntawm MnSi + FeSi + SiAicaBa + SiCic + Carbonizer, thaum HRB335 thiab HRB400 steel qib siv cov txheej txheem ntawm MnSi + FeSi + Aisi + Carbonizer. Txawm li cas los xij, cov khoom lag luam ntawm cov tshuaj ferrosilicon thiab silicon manganese alloys tau nruj zuj zus, thiab cov nqi lag luam tau nce tsis tu ncua, ua rau muaj kev nce ntxiv hauv cov nqi ntawm converter steelmaking thiab compressing cov txiaj ntsig ntawm cov khoom steel. Tsis tas li ntawd, tus nqi rov qab ntawm cov tsoos alloys muaj kev cuam tshuam zoo heev los ntawm kev hloov pauv kev ua haujlwm; yam xws li tapping ntim, qhov kawg kub, thiab slag tawm tuaj yeem ua rau muaj kev hloov pauv loj hauv cov hlau ua tiav, uas ua rau muaj kev ruaj ntseg tsis txaus ntawm cov tshuaj muaj pes tsawg leeg ntawm cov qib steel smelted thiab qis dhau tus nqi rau kev tswj xyuas sab hauv ntawm cov khoom tiav. Tawm tsam qhov teeb meem no, silicon carbide spheres tau tshwm sim thiab tau siv dav.

Cov khoom sib xyaw thiab cov yam ntxwv

Cov ntsiab lus tseem ceeb ntawm silicon carbide spheres yog SiC hais. Cov khoom no yog tsim los ntawm kev txo cov tshuaj tiv thaiv ntawm SiO₂ thiab C, thiab lawv txoj kab uas hla feem ntau yog nyob rau hauv micrometer ntau yam, nrog rau cov duab xws li puag ncig mus rau qhov tsis sib xws. Tsis tas li ntawd, polytetrafluoroethylene, polyurethane thiab lwm yam khoom siv polymer ntxiv rau cov pob silicon carbide, uas tuaj yeem txhim kho qhov yooj yim thiab ua haujlwm ntawm cov pob silicon carbide.
