72 ferrosilicon, nrog kwv yees li 72% cov ntsiab lus silicon, yog qhov tseem ceeb ferrroalloy dav siv nyob rau hauv ntau yam kev lag luam xws li steelmaking, foundry, thiab tshuaj lom neeg engineering. To taub nws cov txheej txheem ntau lawm yog qhov tseem ceeb rau cov kws tshaj lij kev lag luam thiab cov txaus siab nyob hauv thaj teb ntawm Metallurgy.
Raw Khoom Npaj
1
Quartzite
Quartzite pab ua thawj qhov chaw ntawm silicon. Siab - Zoo Quartzite nrog silicon dioxide (sitio₂) cov ntsiab lus ntawm ntau tshaj 97% yog nyiam. Low - IF IRIST QARTZITE ua kom muaj kev coj dawb huv siab dua ntawm cov khoom kawg. Lub sitio₂ hauv quartzite yuav koom nrog hauv kev txo cov tshuaj tiv thaiv tom ntej los ua silicon.
2
Coek
Coke ua raws li tus neeg sawv cev txo tus neeg sawv cev hauv kev tsim cov ferrosilicon 72. Nws yuav tsum muaj cov ntsiab lus ntawm cov hmoov tshauv, thiab lwm yam impurities. Coke Metallurgical coke thiab roj roj coke yog feem ntau siv. Cov pa roj carbon hauv Coke reacts nrog cov pa hauv silicon dioxide kom txo nws rau silicon.
3
Hlau Seem
Scrap steel yog siv los kho cov hlau cov ntsiab lus hauv cov alloy thiab kuj tseem pab txhim kho cov kua dej thiab hluav taws xob zoo ntawm cov nplais. Nws yuav tsum huv si, pub dawb los ntawm cov roj thiab lwm yam paug. Cov hlau hauv cov steel slicap sib txuas nrog silicon los ua ferro silic silic silic silic silic silic

Kev sib tsoo
Yog qhov sib tua yog qhov tseem ceeb rau tau txais72 fesinrog cov yam xav tau. Raws li cov khoom uas yuav tsum muaj silicon thiab hlau cov ntsiab lus hauv cov khoom kawg, cov sib npaug ntawm quartzite, Coke, thiab steel scrap yog xam tau meej. Feem ntau, cov nyiaj quartzite rau cov feem sib npaug, thaum cov nyiaj ntawm Coke thiab steel scrap yog kho raws li cov kev siv ntau lawm. Txheej txheem batching yuav tsum nruj tswj kom ntseeg tau cov khoom zoo sib xws.
Hluav taws xob tshuab hluav taws xob smelting
Them
Lub npaj npaj raw khoom tau them rau hauv lub cub hluav taws xob hauv ib qho kev txiav txim tshwj xeeb. Feem ntau, ib txheej ntawm coke yog thawj nteg nyob rau hauv qab ntawm lub cub tawg, tom qab los ntawm kev sib xyaw ntawm quartzite thiab steel seem. Qhov kev them nqi no pab nyob rau hauv qhov kev pib du ntawm cov txheej txheem smelting thiab kev kho hluav taws xob tau zoo.
Lub zog - rau thiab arc - pib
Ib zaug them, hluav taws xob kom sov hluav taws xob yog siv rau. ARC yog tsim tawm ntawm cov electrodes thiab lub cub hluavtaws. Lub cua sov hnyav los ntawm arc sai sai nce qhov kub ntawm lub cub tawg mus rau lub xeev me me. Thaum lub sijhawm smelting, nruj nruj tswj ntawm cov hluav taws xob hluav taws xob, tam sim no, thiab lub hwj chim yog qhov tsim nyog. Qhov no ua kom muaj cua sov nyob rau hauv cov cub tawg nyob rau hauv cov cub tawg thiab txhawb nqa kev txhim kho kev ua kom du ntawm kev tawm tsam txo.
Txo cov tshuaj tiv thaiv
Raws li cov kub nce, kev tawm tsam kev txo qis tshwm sim. Cov pa roj carbon hauv Coke reacts nrog silicon dioxide hauv quartzite, ua silicon thiab carbon monoxide. Kev siv tshuaj rau cov tshuaj tiv thaiv no yog: sio₂ + 2 C → si + 2 co ↑. Ib txhij, cov hlau los ntawm cov hlau seem sib txuas nrog cov khoom ua si silicon tshiab los ua cov fesi alloy. Cov tshuaj tiv thaiv yuav tsum tau muaj kev kub ntxhov - ib puag ncig kub thiab lub sijhawm txaus. Yog li ntawd, tswj lub siab - lub xeev kub nyob rau hauv lub cub tawg thiab kho qhov cub thiab electrode txoj hauj lwm muaj raws li cov tshuaj tiv thaiv kev nce qib yog qhov tseem ceeb.
Ua kom ua kom ru tsev
Tom qab qee lub sijhawm ntawm smelting, ferro silicon alloy nyob rau hauv lub rauv yuav tsum tau ua kom zoo. Los kho cov muaj pes tsawg leeg thiab cov khoom ntawm cov nplais, impurities xws li sulphorus hauv alloy tuaj yeem tshem tawm ntxiv, yog qhov zoo ntawm cov silicon ferro. Thaum lub sij hawm ua kom zoo dua qub txheej txheem, cov ntaub ntawv tso ua ke xws li txiv qaub yuav tau ntxiv rau kev txhim kho kom zoo thiab ua kom zoo ntawm cov swb.
Casting thiab shaping
Thaum lub ferrosilicon alloy ncav tau muaj pes tsawg leeg tau muaj pes tsawg leeg thiab ntsuas kub, tus tophole ntawm cov hluav taws xob kom qhib, thiab cov molten alloy tau hliv rau hauv lub tsev. Yuav tsum tau txais kev saib xyuas kom tiv thaiv kom tiv thaiv kom tiv thaiv ntau ntawm cov molten alloy thiab huab cua kom tsis txhob oxidation.
Lub ladle uas muaj Molten Alloy tau thauj mus rau thaj chaw ua ke thiab hliv rau hauv cov pwm tshwj xeeb. Cov duab thiab qhov loj me ntawm cov pwm raug txiav txim siab raws li cov khoom lag luam cov khoom lag luam. Cov pwm cov pwm suav nrog suav cov pwm pwm thiab cov pwm tshuab granule. Raws li cov molten alloy txias thiab solidifies hauv pwm, nws yuav siv rau ntawm cov duab yam xav tau.
Tshuaj xyuas thiab ntim khoom
Kev kuaj thiab tshuaj xyuas
Cov qauv yog tshwm sim los ntawm kev cameat Silicon cov khoom lag luam los tshuaj xyuas lawv cov tshuaj lom neeg, cov khoom siv lub cev, thiab lwm yam ntsuas. Qhov no kom ntseeg tau tias cov khoom lag luam zoo ua tau raws li cov qauv muaj feem rau 72% Ferro Silicon. Yog tias cov khoom lag luam zoo tsis tau raws li qhov yuav tsum tau ua, kev ntsuas tsim nyog yuav tsum tau ua rau kev hloov kho lossis rov ua raws sijhawm.
Ntim thiab Warehousing
Tus soj ntsuam thiab tsim nyog ferrosilicon cov khoom lag luam tau ntim raws cov neeg siv khoom. Feem ntau, ntim ntim yog siv los tiv thaiv cov khoom lag luam los ntawm kev nqus dej los yog oxidized thaum lub sijhawm khaws cia thiab tsheb thauj mus los. Cov khoom ntim tau ntim tau ntim rau hauv lub tsev rau khoom, tos cov zaub mov xa tuaj.
Hauv kev xaus, kev tsim covFerrosilicon 72%koom nrog ntau cov kauj ruam nyuaj, los ntawm raw khoom npaj rau lub ntim kawg ntawm cov khoom. Txhua kauj ruam ib qib twg yuav tsum tau tswj nruj thiab ua haujlwm kom meej kom muaj kev tsim cov qib siab - zoo72 # fesiuas tau raws li cov kev xav tau ntawm ntau yam kev lag luam.
