Kev tsim khoom

Kev tsim khoom ntawm Metallurgical Qib Silicon 441 yuav tsum muaj cov txheej txheem nruj, thiab txhua kauj ruam cuam tshuam ncaj qha rau purity thiab zoo ntawm cov khoom kawg:

Raw khoom kuaj thiab pretreatment:

Xaiv high-purity silica (kom txo cov impurities), qis-sulfur thiab qis- tshauv coke (raws li tus neeg sawv cev txo qis), thiab zuaj thiab tshuaj xyuas cov ntaub ntawv raw kom ntseeg tau tias qhov loj me (silica loj feem ntau yog 50-150mm, coke loj yog 20-80mm) los txhim kho smelting efficiency. cov

Electric arc rauv smelting:

Cov ntaub ntawv raw pretreated tau muab tso rau hauv hluav taws xob arc rauv nyob rau hauv ib qho kev faib ua feem, thiab qhov kub siab (1800-2000 degree) tsim los ntawm electrode ua rau txo qis cov tshuaj tiv thaiv. SiO₂ nyob rau hauv silica yog txo mus rau metallic silicon los ntawm carbon: SiO₂ + 2C → Si + 2CO↑. Tag nrho cov txheej txheem yuav tsum tau tswj nruj ntawm qhov cub kub, lub sij hawm tshuaj tiv thaiv thiab cov khoom siv raw kom tsis txhob muaj ntau dhau ntawm impurities.

Refining thiab impurity tshem tawm:

Tom qab smelting, impurities xws li txhuas, hlau, thiab calcium nyob rau hauv molten silicon raug tshem tawm ntxiv los ntawm refining txheej txheem xws li nag lossis daus thiab tshuab (xws li argon) kom ntseeg tau tias cov impurity cov ntsiab lus raws li 441 qauv qauv. cov

Cooling thiab crushing:

Cov molten silicon refined yog cam khwb cia rau hauv cov duab, crushed thiab tshuaj ntsuam tom qab ntuj txias, thiab ua tiav rau hauv ntau qhov sib txawv (xws li 10-100mm blocks, 1-3mm granules, thiab lwm yam) raws li cov neeg siv khoom xav tau, thiab thaum kawg ntim thiab khaws cia.

FAQ

Q: Qhov txawv ntawm 441 thiab 553 yog dab tsi? Puas tsim nyog?

A: 441 yog 5%-10% kim dua 553. Txawm tias nws tsim nyog nws nyob ntawm koj qhov khoom muag. Rau high-end aluminium alloys, silicone, thiab tshwj xeeb hlau, siv me ntsis ntxiv ntawm 441 yog qhov tsim nyog.

Q: Koj 441 puas tuaj yeem tswj tau cov ntsiab lus silicon siab dua 99.1%?

A: Yog. Peb kuaj txhua batch ua ntej xa zaub mov kom ntseeg tau tias silicon Ntau dua lossis sib npaug rau 99.1%. Cov ntaub ntawv xeem tau suav nrog cov khoom.

Q: Dab tsi yog qhov zoo ntawm kev siv 441 tshaj 553 rau txhuas alloys?
