Kodi Ferro Alloys Ndi Chiyani?

Aloyi ndi chosakaniza kapena cholimba chopangidwa ndi zitsulo. Momwemonso, ferroalloy ndi chisakanizo cha aluminiyamu chosakanikirana ndi zinthu zina monga manganese, aluminiyamu kapena silicon mochuluka. Alloying bwino thupi katundu wa zinthu, monga kachulukidwe, reactivity, Young modulus, madutsidwe magetsi ndi matenthedwe madutsidwe. Chifukwa chake, ma ferroalloys amawonetsa zinthu zosiyanasiyana chifukwa zosakaniza zachitsulo zosiyanasiyana mosiyanasiyana zimawonetsa zinthu zambiri. Kuphatikiza apo, alloying amasinthanso mawonekedwe azinthu zamakolo, kutulutsa kuuma, kulimba, ductility, ndi zina zambiri.
Zogulitsa za Ferroalloy
Zopangira zazikulu za ferroalloys ndi ferroaluminium, ferrosilicon, ferronickel, ferromolybdenum, ferrotungsten, ferrovanadium, ferromanganese, ndi zina zotero. Kusiyanitsa pang'ono kutentha, kutentha kapena kapangidwe kake kumatha kupanga ma aloyi okhala ndi zinthu zosiyana kwambiri. Ntchito zazikulu za ferroalloys ndi zomangamanga, zokongoletsera, magalimoto, mafakitale achitsulo ndi zida zamagetsi. Makampani azitsulo ndi omwe amagula kwambiri ma ferroalloys chifukwa ma ferroalloys amapereka zinthu zosiyanasiyana kuzitsulo zazitsulo ndi zitsulo zosapanga dzimbiri.

Ferromolybdenum
Ferromolybdenum nthawi zambiri amagwiritsidwa ntchito popanga chitsulo cha aloyi kuti apititse patsogolo kuuma, kulimba komanso kulimba kwachitsulo. Zomwe zili molybdenum mu ferromolybdenum nthawi zambiri zimakhala pakati pa 50% ndi 90%, ndipo kugwiritsa ntchito mosiyanasiyana kumafunikira zinthu zosiyanasiyana za ferromolybdenum.

Ferrosilicon
Ferrosilicon nthawi zambiri imakhala ndi silicon 15% mpaka 90%, yokhala ndi silicon yayikulu. Ferrosilicon ndi chinthu chofunika kwambiri cha aloyi, ndipo ntchito yake yaikulu ndi kupanga zitsulo. Ferroalloys amathandizira kutulutsa chitsulo ndi chitsulo. Kuphatikiza apo, imathandizanso kulimba, mphamvu komanso kukana dzimbiri. China ndiye wopanga wamkulu wa ferrosilicon.

Ferrovanadium
Ferrovanadium nthawi zambiri amagwiritsidwa ntchito popanga zitsulo za aloyi kuti apititse patsogolo mphamvu, kuuma komanso kuvala kukana kwachitsulo. Vanadium yomwe ili mu ferrovanadium nthawi zambiri imakhala pakati pa 30% ndi 80%, ndipo kugwiritsa ntchito mosiyanasiyana kumafuna zinthu zosiyanasiyana za ferrovanadium.

Ferrochrome
Ferrochrome, yomwe imadziwikanso kuti chromium iron, nthawi zambiri imakhala ndi 50% mpaka 70% chromium polemera. Kwenikweni, ndi aloyi ya chromium ndi chitsulo. Ferrochrome imagwiritsidwa ntchito kwambiri popanga zitsulo, zomwe zimawerengera pafupifupi 80% yazakudya padziko lonse lapansi.

Nthawi zambiri, ferrochrome imapangidwa mu ng'anjo zamagetsi zamagetsi. Kapangidwe kake kamakhala ndi carbothermic reaction, yomwe imachitika pakutentha kwambiri komwe kumayandikira 2800 ° C. Kuchuluka kwa magetsi kumafunika kuti afikire kutentha kwakukuluku. Choncho, ndi okwera mtengo kwambiri kupanga m'mayiko omwe ali ndi magetsi okwera mtengo. Opanga kwambiri a ferrochrome ndi China, South Africa ndi Kazakhstan.

Ferrotungsten
Ferrotungsten amagwiritsidwa ntchito popanga chitsulo cha aloyi kuti awonjezere kuuma, kukana kuvala komanso kukana kutentha kwachitsulo. Zomwe zili mu tungsten mu ferrotungsten nthawi zambiri zimakhala pakati pa 60% ndi 98%, ndipo ntchito zosiyanasiyana zimafunikira zinthu zosiyanasiyana za ferrotungsten.
Kupanga ferrotungsten makamaka ikuchitika ndi kuphulika ng'anjo ironmaking kapena ng'anjo magetsi njira. Popanga chitsulo chamoto, miyala yokhala ndi tungsten imayikidwa mu ng'anjo yoyaka moto pamodzi ndi coke ndi miyala yamchere kuti asungunuke kuti apange ferroalloys yokhala ndi tungsten. Mu njira ya ng'anjo yamagetsi, ng'anjo yamagetsi yamagetsi imagwiritsidwa ntchito kutentha ndi kusungunula zipangizo zomwe zili ndi tungsten kukonzekera ferrotungsten.

Ferrotitanium
Titaniyamu mu ferrotungsten nthawi zambiri imakhala pakati pa 10% ndi 45%. Kupanga ferrotungsten makamaka ikuchitika ndi kuphulika ng'anjo ironmaking kapena ng'anjo magetsi njira. China ndi amodzi mwa omwe amapanga ferrotungsten padziko lonse lapansi.

Kugwiritsa ntchito ferroalloys

Aloyi kupanga zitsulo
Ferroalloys ndi chimodzi mwazinthu zofunika kwambiri popangira chitsulo cha alloy. Powonjezera mitundu yosiyanasiyana ya ferroalloys (monga ferrochrome, ferromanganese, ferromolybdenum, ferrosilicon, etc.) ku chitsulo, katundu wa chitsulo akhoza kusintha, monga kuwongolera kuuma, mphamvu, kuvala kukana, kukana dzimbiri, etc., kupanga zitsulo zambiri. oyenera madera osiyanasiyana a uinjiniya ndi kupanga.
Kupanga chitsulo
Chitsulo chachitsulo ndi chinthu chodziwika bwino choponyera, ndipo ma ferroalloys amagwira ntchito yofunika kwambiri popanga chitsulo. Kuonjezera gawo lina la ferroalloys kumatha kukonza makina, kukana kuvala ndi kukana kwa dzimbiri kwachitsulo choponyedwa, ndikupangitsa kuti ikhale yoyenera kupanga zida zamakina, mbali zamagalimoto, mapaipi, ndi zina zambiri.

Makampani opanga magetsi
Ferroalloys amagwiritsidwanso ntchito m'makampani opanga magetsi, monga zida zoyambira zosinthira magetsi. Aloyi chitsulo ali wabwino maginito permeability ndi otsika hysteresis, amene angathe kuchepetsa mphamvu kutaya kwa thiransifoma mphamvu.

Munda wa zamlengalenga
Kugwiritsiridwa ntchito kwa ferroalloys m'munda wamlengalenga ndikofunikanso kwambiri, monga kupanga magawo apangidwe ndi mbali za injini za ndege ndi maroketi, zomwe zimafuna kuti zigawozi zikhale ndi makhalidwe monga opepuka, mphamvu zazikulu komanso kutentha kwambiri.

Chemical Viwanda
M'makampani opanga mankhwala, ma ferroalloys nthawi zambiri amagwiritsidwa ntchito ngati zonyamulira zonyamula ma organic synthesis reaction, kuyeretsa gasi ndi njira zina.

Refractory zipangizo
Ma ferroalloys ena angagwiritsidwenso ntchito pokonzekera zida zotsutsa kuti apititse patsogolo kutentha kwa zinthuzo. Nthawi zambiri amagwiritsidwa ntchito popanga zinthu zokanira m'mafakitale monga zitsulo ndi zitsulo.
