Ferro Silicon Lump

Ferro silicon lumps yog alloys tsim los ntawm smelting nyob rau hauv hluav taws xob furnaces siv coke, steel seem, thiab quartz (los yog silica xuab zeb) ua raw khoom. Txij li thaum silicon yooj yim ua ke nrog oxygen los ua silicon dioxide, ferro silicon feem ntau yog siv los ua deoxidizer hauv steel ua. Nyob rau tib lub sijhawm, cov tshuaj tiv thaiv exothermic ntawm silicon dioxide tsim tawm cov cua kub tseem ceeb, uas yuav pab txhawb cov hlau kub kub thaum deoxidation. Tsis tas li ntawd, ferro silicon ua hauj lwm raws li ib tug alloying ntsiab additive, dav siv nyob rau hauv qis- alloy structural steels, caij nplooj ntoos hlav steels, bearing steels, tshav kub- resistant steels, thiab hluav taws xob silicon steels.

Cov txheej txheem tsim khoom ntawm ferro silicon lumps muaj tsib theem tseem ceeb:raw khoom npaj, batching thiab them, hluav taws xob rauv smelting, hlau tapping thiab casting, thiab tiav thiab kev soj ntsuam zoo.

I. Raw Material Preparation

• Core Raw Khoom: Quartzite, carbon txo tus neeg sawv cev, hlau qhov chaw, electrode paste.
• Ua ntej-kev kho mob: Sib tsoo, ntxuav, thiab qhuav silica kom tshem tawm cov impurities. Qhuav cov neeg ua haujlwm kom txo cov dej noo. Ntxuav cov hlau qhov chaw ntawm cov roj thiab xeb, tom qab ntawd faib thiab khaws cia los ntawm kev sib xyaw.

II. Kev them nyiaj yug thiab cub Loading

• Kev sib xyaw: Uniformly muab silica, txo cov neeg ua haujlwm, thiab cov khoom siv hlau hauv qhov kev faib ua feem kom ntseeg tau tias muaj kev kub ntxhov.
• Kev Them Nyiaj: Ua haujlwm txuas ntxiv lossis batch them kom thauj khoom sib tov rau hauv lub tshuab hluav taws xob hluav taws xob (peb-theem electrodes). Sib sib zog nqus ntxig electrodes rau hauv cov txheej txheem los tsim ib qho faus arc, tiv thaiv kev tawg thiab hluav taws xob pov tseg.

III. Hluav taws xob rauv Smelting

• Fais fab-Rau thiab cua sov: Pib electrode arcing, maj mam nce lub zog kom txog thaum lub cub tawg kub txog 1800-2000℃. Cov pa roj carbon monoxide txo cov silica. Hlau oxides nyob rau hauv cov hlau qhov chaw raug txo, thiab silicon reacts nrog hlau los tsim ferro silicon alloy.
• Furnace Condition Control: Saib xyuas tam sim no, qhov hluav taws xob, txoj haujlwm electrode, thiab tus nqi txo qis. Kho qhov them zaus thiab lub cub tawg ramming kom ruaj khov crucible cheeb tsam thiab cov hlau tsis sib xws.

IV. Hlau Tapping thiab Casting

• Hlau Tapping: Thaum ua tiav lub hom phiaj muaj pes tsawg leeg thiab qhov kub thiab txias, qhib lub tapping kais kom tso cov ferrosilicon molten rau hauv lub ladle.
• Casting: Pour molten FeSi los ntawm lub ladle rau hauv ingot pwm los yog casting tshuab, tswj ingot thickness (FeSi75 Tsawg dua los yog sib npaug rau 100mm, FeSi45 Tsawg dua los yog sib npaug rau 150mm) los tiv thaiv kev sib cais. Tso cai rau ntuj txias lossis yuam cua txias kom khov rau hauv FeSi ingots.

V. Kev Ua tiav thiab Kev Tshuaj Xyuas Zoo

• Crushing thiab tshuaj ntsuam: Crushed txias FeSi ingots thiab tshuaj ntsuam rau qhov sib txawv particle loj rau cov neeg siv khoom.
• Kev soj ntsuam zoo: Kuaj cov khoom muaj pes tsawg leeg thiab cov ntsiab lus impurity. Ua kom pom kev tshuaj xyuas kom tsis txhob muaj cov kab noj hniav shrinkage lossis tawg. Ntim thiab khaws cia thaum dhau kev kuaj xyuas.
