silicon yapompopompo Chithunzi Chowonetsedwa

silicon nthawi yomweyo

Instant silicon Metal silicon, yomwe imadziwikanso kuti silikoni yamafakitale, ndi chowonjezera chomwe chimagwiritsidwa ntchito kwambiri pakusungunula zitsulo ndipo chimagwiritsidwa ntchito ngati chochepetsera pakusungunula.Silicon ndi chinthu chabwino muzitsulo za aluminiyamu, ndipo ma aloyi ambiri opangidwa ndi aluminiyamu amakhala ndi silicon.Silicon pompopompo ndi pamwamba pa silicon chitsulo kuphatikiza flux.Ntchito ya flux ndi kupanga kutentha kwambiri m'kati zitsulo smelting, kuti pakachitsulo zitsulo amasungunula mwamsanga, ndi mmene kutentha kwa flux zambiri si mkulu, pafupifupi 740 digiri Celsius, kotero mtundu uwu wa Zitsulo pakachitsulo. ndi flux wowonjezera amatchedwanso instant silicon.Amagwiritsidwa ntchito posintha zomwe zili mu silicon mu ma aloyi a aluminiyamu.

Ubwino wogwiritsa ntchito silicon nthawi yomweyo

1. Liwiro losungunuka ndilothamanga kwambiri, zomwe zimachitika mwachangu, ndipo nthawi imasungidwa.

2. Zomwe zili pamwambazi ndi 95%, zomwe zingathe kulamulira ndendende kuchuluka kwa silicon yowonjezeredwa, ndikukonzekera mwamsanga gawo lililonse la aluminium-silicon alloy.

3. Ndizosavuta kugwiritsa ntchito, ingoikani pamwamba pa aluminiyumu yamadzimadzi, ikani ndikugwedeza.Mlingo wochira ndi wamkulu kuposa 90%.

4. Njira yabwino yosinthira ma aluminiyamu-silicon aloyi wapakatikati.Imachotsa ma inclusions ambiri ndi zinthu zovulaza zomwe zimabweretsedwa mosavuta mu aluminium-silicon alloys, ndikupewa kugwiritsa ntchito zinyalala ndi zotayidwa zosiyanasiyana pokonzekera ma alloys a aluminium-silicon, omwe ndi ovuta kuwongolera mtundu wa aloyi yomaliza ya aluminium.

5. Kuchepetsa kwambiri kutentha kosungunuka, kuchepetsa kwambiri nthawi yosungunuka, ndi kuchepetsa kwambiri mtengo wa zosakaniza za alloy.

Kugwiritsa ntchito

Chingwe chilichonse chokhala ndi silicon kapena aluminiyumu yopangidwa ndi golide.Kugwiritsa ntchito kutentha: 740-770 ℃ (kutentha kwapamwamba, kumapangitsanso bwino)

Momwe mungagwiritsire ntchito

Zonse zikasungunuka, gwedezani bwino ndikutenga zitsanzo kuti muwunike.Werengani kuchuluka kwa silicon yosungunuka mwachangu malinga ndi zotsatira za kusanthula.Pamene aluminiyamu yosungunuka ifika pa 740-770 ° C (njira yowonjezeretsa silicon ndi endothermic reaction, kutentha kwachitsulo chosungunuka kuyenera kutenthedwa kuti kutentha kusatsike kuposa 740 ° C), kuponyera silicon pompopompo pa chosungunuka. aluminium pamwamba kuti mugwiritse ntchito, ndikusindikiza belulo mu aluminiyamu yosungunuka.Onetsetsani kwa mphindi 2-5.Mafotokozedwe a mankhwala: Zomwe zili pa silicon ndi 95%, ndipo zimatha kusungunuka mofulumira pa kutentha kochepa, zomwe zimachepetsa kwambiri mtengo wa zosakaniza za aloyi, ndipo zimatha kukonzekera mwamsanga aloyi iliyonse ya silicon-aluminium yokhala ndi silicon;kuwongolera kalembedwe ndikolondola kwambiri, ndipo kuchuluka kwa zophatikizika ndi zinthu zovulaza zomwe zimabweretsedwa mosavuta mu alloy master zimachotsedwa.Zonyansa, kupewa kugwiritsa ntchito zinyalala zotayidwa zotayidwa kukonzekera zotayidwa-pakachitsulo mbuye aloyi ndi zotsatira pa khalidwe la aloyi chomaliza zotayidwa zovuta kulamulira.
