Silicon Slag yog los ntawm byproduc tsim hauv kev lag luam ntau lawm (xws li cov txheej txheem smelting ntawmSilicon Hlauthiabferrosilicon). Nws lub tseem ceeb tivthaiv yog silicon oxide, thiab nws tseem muaj qee qhov nyiaj ntawm Si, FE thiab lwm cov neeg tawg nkoj. Silicon Slag siv nyob rau hauv daim teb ntawm steelmaking yog feem ntau yog cov khoom lag luam thiab kho kom haum rau qhov yuav tsum tau ua ntawm steelmaking deoxidation. Piv txwv li, hauv kev tsim cov silicon hlau, lub slag tawm ntawm cov ore-}} READ cov khoom siv rau steelmaking tom qab tau ua los ntawm crushing, tshuaj ntsuam thiab lwm yam txheej txheem.

Silicon caij hauv Silicon Slag muaj lub zog txo cov cuab yeej. Nyob rau hauv cov kev mob siab ntawm steelmaking, nws tuaj yeem hnov cov pa roj oxygen nyob rau hauv molten steel los tsim cov roj av los ua cov silicon dioxide, yog li ua tiav lub hom phiaj ntawmdeoxidationCov. Nyob rau tib lub sijhawm, lwm yam hauv silicon slag xws li ib qho kev cuam tshuam hauv Molten hlau, uas yuav muaj qee yam cuam tshuam ntawm cov hlau thiab kev ua haujlwm ntawm Molten Steel.

Deagidation nyob rau hauv lig theem ntawm tshuab

Hauv kev hloov pauv cov txheej txheem, C, MN thiab lwm cov ntsiab lus nyob rau hauv cov hlau molten hlau yog tsuas yog muab tshem tawm los ntawm tshuab pa hauv lub sijhawm ntxov. Nyob rau hauv lub caij nyoog qeeb ntawm tshuab tawg, Molten steel tseem muaj qee qhov ntau ntawm cov pa oxygen. Nyob rau lub sijhawm no, nws yog haum rau ntxiv silicon slag rau deoxidation. Tus si nyob rau hauv lub silicon slag reacts nrog oxygen nyob rau hauv molent steel los tsim silicon dioxide, yog li txo cov ntsiab lus oxygen ntawm Molten hlau. Tsis tas li ntawd, tus pob loj ntawm converter steelmaking loj, thiab kev siv ntawm silicon slag, tus nqi pheej yig, tuaj yeem txo cov nqi ntau lawm.

Kawg taw tes sib haum

When converter steelmaking is close to the end point, the composition of the molten steel needs to be fine-tuned to meet the requirements of the target steel grade. Nws tsis tuaj yeem tsuas yog deaxidize, tab sis kuj ntxiv ib qho nyiaj ntawm silicon rau cov hlau molten, thiab pab kho cov khoom sib xyaw ua ke ntawm Molten hlau. Yog li ntawd, nws yog qhov tsim nyog kom siv cov seelicon slag nyob rau theem no.

Cov txheej txheem hluav taws kub:

Deoxidation thaum kawg ntawm oxidation

Lub sijhawm oxidation ntawm hluav taws xob rauv stat steelmak yog mas kom tshem impurities xws li phosphorus thiab carbon hauv cov hlau molten. Cov ntsiab lus oxygen ntawm cov hlau Molten ntawm qhov kawg ntawm oxidation yog tus kheej. Nws tuaj yeem raug ntxiv ua Deagidizer nyob rau lub sijhawm no kom hnov mob nrog oxygen nyob rau hauv lub molten steel los ua kom tiav deoxidation. Ib qho ntxiv, kev tswj hwm ntawm kev sib xyaw ua ke ntawm Molten Steel thaum lub tshuab hluav taws xob hluav taws xob ntau ntxiv, siv tau zoo dua ntawm cov hluav taws xob hluav taws xob sib xyaw ntawm Molten hlau.

Refining Theem

Nyob rau hauv lub chaw ua kom zoo ntawm cov roj hluav taws xob hluav taws xob loj, nws yog qhov tsim nyog yuav txo cov pa oxyging hauv cov hlau thiab tshem tawm cov impurities los txhim kho cov purity ntawm cov hlau. Nws tuaj yeem siv ua ke nrog lwm tus neeg sawv cev kom ua kom cov txheej txheem ua kom zoo dua qub kom ua lub luag haujlwm hauv kev ua kom yuag, uas pab kom cov txheej txheem kev txhim kho kom huv.

Qhib {{0- Hearth statmaking txheej txheem (txawm hais tias maj mam tshem tawm, qee tus tseem siv):

Qhib - Hearth Steelmaking siv sijhawm ntev, thiab thaum lub sij hawm statmaking, thiab qhov sib xyaw thiab kub ntawm Molten Steel hloov pauv yooj yim. Nws tuaj yeem raug ntxiv rau deoxidation ntawm ntau theem, xws li thaum lub sij hawm yaj thiab ua kom zoo nkauj ntawm cov khoom sib xyaw ntawm Molygen cov ntsiab lus hauv cov hlau. Nyob rau tib lub sijhawm, tus nqi qis ntawm Silicon Slag kuj tau ntsib tus nqi tswj yuav tsum muaj ntawm kev qhib- Hearth} Heubth steelmaking.

Ladle kev kho txheej txheem ua ntej txuas ntxiv cam khwb cia:

Molten Steel yuav tsum tau kho ntxiv nyob rau hauv lub tsev ua ntej txuas ntxiv ua ntej kom ntseeg tau tias qhov zoo ntawm Molten Steel tau ua raws li qhov yuav tsum ua ntawm nrib pleb. Ntxiv silicon slag mus rau lub ladle tuaj yeem ua qhov kawg deoxidation thiab zoo- kev sib xyaw ntawm MolenTater cov ntsiab lus ntawm Molten Steel thaum lub sij hawm txuas ntxiv ua cov txheej txheem txuas ntxiv.
