Silicon hlau 421 Block

Hlau silicon 421yog ib qho txawv ntawm cov hlau silicon nrog cov yam ntxwv thiab kev siv. Nws pom kev siv dav hauv ntau qhov kev lag luam vim nws cov khoom tshwj xeeb.

Hauv kev lag luam metallurgy, hlau silicon 421 plays lub luag haujlwm tseem ceeb hauv cov txheej txheem deoxidation, txhim kho qhov zoo thiab cov khoom ntawm cov hlau uas ua tau. Nws muaj nyob rau hauv aluminium alloys txhim kho lawv cov neeg kho tshuab thiab lub cev yam ntxwv, ua rau lawv haum rau ntau yam kev siv.

Tsis tas li ntawd, nyob rau hauv lub realm ntawm semiconductor manufacturing, hlau silicon 421 yog ib qho tseem ceeb raw khoom. Nws txhawb kev tsim cov khoom siv hluav taws xob ua haujlwm siab, ua kom muaj kev nce qib hauv cov khoom siv hluav taws xob thiab thev naus laus zis.

Tam sim no, cov txheej txheem ntau lawm ntawm cov pa roj carbon thermal txoj kev tsim cov hlau silicon hauv Suav teb: Txoj kev siv feem ntau yog siv silica los ua cov khoom siv raw, thiab siv roj av coke, charcoal, wood chips, low-ash thee, etc. txo cov neeg ua haujlwm, thiab ua kom kub kub smelting hauv cov ntxhia thermoelectric rauv kom txo cov hlau silicon los ntawm silica. Nws yog slag-dawb faus arc high-temperature smelting txheej txheem.

Nws tuaj yeem pom tias daim ntawv thov ntawm cov hlau silicon yog qhov dav. Nws yog dav siv nyob rau hauv aerospace, electronics thiab hluav taws xob, kev tsim kho, kev thauj mus los, lub zog, tshuaj textiles, zaub mov, lub teeb kev lag luam, kev kho mob, kev ua liaj ua teb thiab lwm yam lag luam. Raws li kev txheeb cais, xyoo 1985, lub ntiaj teb tau siv txog 500,{2}} tons ntawm hlau silicon nyob rau hauv tag nrho, ntawm cov hlau silicon siv nyob rau hauv aluminium alloys suav txog li 60%, uas siv hauv cov organic silicon tsawg dua 30%, thiab uas siv nyob rau hauv semiconductors suav txog li 3%, thiab tus so yog siv nyob rau hauv steel smelting thiab precision ceramics, thiab lwm yam.

Kev siv dav ntawm cov hlau silicon qhia tau tias nws lub luag haujlwm tseem ceeb thiab muaj txiaj ntsig hauv ntau qhov chaw. Nws cov khoom thiab cov yam ntxwv ua rau nws yog ib qho tseem ceeb hauv ntau cov txheej txheem kev lag luam thiab kev siv. Nrog rau kev txhim kho txuas ntxiv thiab kev nce qib ntawm cov thev naus laus zis, daim ntawv thov ntawm cov hlau silicon yuav tsum txuas ntxiv nthuav dav thiab ua lub luag haujlwm tseem ceeb ntxiv.
