Silicon hlau 97

Silicon hlau 97, tseem hu ua substandard silicon los yog industrial silicon, feem ntau yog siv los ua ib qho additive rau non-ferrous alloys. Cov txheej txheem tsim khoom ntawm 97 metallic silicon yog qhov yooj yim thiab ua tau. Los ntawm kev siv cov hluav taws xob sib xyaw, roj av coke, thiab cov thee bituminous los txo cov silicon ore, ua ke nrog slag refining, thiab siv cov kev taw qhia kev ua kom muaj zog kom tshem tawm ntau yam impurities, nws ua tau raws li cov kev cai ntawm qib siab-purity silicon, yog li txhim kho qhov zoo ntawm 97 metallic silicon khoom thiab haum rau kev lag luam ntau lawm.

Silicon hlau 97 yog cov khoom lag luam tsim los ntawm smelting silica thiab xiav charcoal nyob rau hauv lub cub hluav taws xob, nrog rau cov ntsiab lus tseem ceeb ntawm silicon cov ntsiab lus ntawm txog 98% (nyob rau hauv xyoo tas los no, 99.99% Si cov ntsiab lus tseem suav nrog 97 silicon), thiab cov khoom seem tsis zoo. yog hlau, txhuas, calcium, thiab lwm yam.

Cov kauj ruam rau smelting 97 metallic silicon yog:

a. Txuas lub hwj chim ntawm lub tshuab hluav taws xob ore, ua kom sov lub tshuab ua kom sov lub cev, nce qhov kub ntawm lub cub tawg mus rau 500 degree -700 degree, thiab ntxiv cov silicon ore raw khoom rau hauv lub cub tawg tom qab crushing, tshuaj xyuas, tu, thiab ziab;

b. Ntxiv cov khoom sib xyaw rau hauv lub qhov cub arc submerged thiab kub txog 1600 degree -1900 degree rau calcination thiab melting, ua rau txo qis cov tshuaj tiv thaiv;

c. Tom qab kev txo cov tshuaj tiv thaiv tiav lawm, slag forming tus neeg sawv cev yog ntxiv los ntawm qhov kawg pub, thiab cov ore cub tawg yog rhuab mus rau 1200 degree -1400 degree . Ib qho tshuaj tiv thaiv tshwm sim rau slag refining. Tom qab lub slag refining tiav lawm, cov kua sib tov tso cai rau sawv ntsug, thiab cov kua silicon ntab tuaj thiab sib cais los ntawm theem slag;

d. Cov kua silicon tom qab slag refining ntws tawm ntawm lub qhov hluav taws xob ntawm submerged arc rauv. Thaum lub sij hawm tus txheej txheem no, lub tshuab cua txias yog qhib rau kev taw qhia solidification;

e. Los ntawm kev siv cov cuab yeej uas qhov sib npaug sib cais coefficient ntawm impurities nyob rau hauv cov txheej txheem crystallization ntawm silicon kua yog tsawg tshaj li 1, txoj kev taw qhia solidification yog saws mus txuas ntxiv cais impurities los ntawm cov khoom-kua interface rau hauv silicon kua. Tom qab cov kua silicon yog tag nrho crystallized, lub siab impurity concentration ib feem yog mechanically tshem tawm kom tau 97 metallic silicon.
