OAO "Lipetsk Iron Emikhulu Kakhulu 'Svobodny Sokol" »: umlando, ukukhiqizwa, imikhiqizo

OAO "Lipetsk Iron Emikhulu Kakhulu 'Svobodny Sokol" "- ibhizinisi endala kwedolobha Lipetsk, siphawula indaba wakudala. It ngokukhethekile imikhiqizo eyingqayizivele eRussia - ipayipi lamanzi ka ductile cast iron.

Imininingwane zomlando

Lipetsk Iron Works yasungulwa ngo 1899 by osomabhizinisi waseBelgium. Njengoba izindawo zokukhiqiza zitholakala edolobhaneni Sokol, kamuva ngemvume kwemikhawulo emzini Lipetsk, inkampani okuthiwa Sokolsky ironworks. Uma zigcwele, inkampani wangena 1900 emva kwethulwa amaziko amabili kuqhuma.

Phakathi nenkathi yamaSoviet, ukukhiqizwa siqanjwe kabusha e Lipetsk Iron Emikhulu Kakhulu 'Svobodny Sokol ". Kwaphela iminyaka eminingi inkampani wahlanganyela ukukhiqizwa eliphezulu yensimbi ezimbonini. Kusukela ngo-1934, le nhlangano wathutha ukukhululwa kwamanzi-ingcindezi cast iron amapayipi.

Ironmaking

Namuhla, i-Lipetsk Metallurgical Plant siqukethe imikhiqizo 14. Isizinda eziyinhloko truboliteyny nezitolo. Blast esithandweni isitshalo has amaziko amabili umthamo 700 m ³ ngesethi ekubunjweni futhi imishini elisizayo ngamunye. Zinikeza ukukhululwa okusamanzi kanye ingulube yensimbi. Esitolo nemikhiqizo Foundry ingulube yensimbi ezigabeni ezehlukene.

Ngenxa yenqwaba encane kuqhuma esithandweni steelmakers bayakwazi aphele metal high kakhulu noma eliphi inani, ngisho izinto eziningi ezincane. ekubunjweni ubuchwepheshe evumela ukufeza high metal, isakhiwo zazo kuyahluka izakhiwo mechanical ezinzile, ukungabi khona cementite khulula kule microstructure, ukuthambekela ubuncane emnyangweni onqenqemeni futhi oncomekayo workability. Sakaza yensimbi ikhiqizwa ingots-9 kg, kulula ukuthutha ngobuningi yizimpahla railcars.

ipayipi Ukukhiqiza

Ngo-1990, ngaphambi kokuwa zase-USSR, ngesikhathi Lipetsk Metallurgical Plant laqanjwa ifakwe imishini yesimanje truboliteyny isitshalo ukwenziwa amanzi-ingcindezi amapayipi ezensimbi ductile, isakhiwo lapho graphite uku eyindilinga (globular) isimo. Le nto ehlanganisa izakhiwo unique - izakhiwo mechanical ukugqwala ukumelana lensimbi:

• ukunwebeka okusezingeni eliphezulu;
• nomthelela ukumelana;
• amandla eqine;
• ductility.

Lezi izakhiwo etholakala ngokuzikhandla ukuguqulwa ezivamile grey cast magnesium. Kushintshwe graphite izinhlayiya e ductile ezibonakalayo ngesimo sphere ngesibonakhulu, ubuhlalu. Abasusa ukwakheka kanye esiphelweni imifantu, okwenza cast iron kokubili ubulukhuni futhi ductility.

Castings okwenyanga

Lipetsk Metallurgical Plant kahle ukukhiqizwa batch:

• Plates ifriji lwaluyophola amanzi lwaluyophola esithandweni kuqhuma. Zenziwa low-ingxubevange chromium cast iron ezahlukene Ubukhulu isisindo kusuka amathani 1.58 ukuze 2.9.
• Bamba ithambo emikhombeni kanye slag kusuka kuqhuma amaziko.
• Castings yensimbi amamaki MF-15, MF-20 nge Ubukhulu 3x1,2x1 m kanye isisindo esiphezulu 3.5 tonnes.
• Aluminium ingxubevange Castings kuya kwezingu-8 kg.

Lesi sitshalo afuna ukuqala ukukhiqizwa izingxenye podnasadochnogo kudivayisi izitofu kuqhuma amaziko (podnasadochnyh grid, ukusekela amakholomu).

"Synthicom"

Isitshalo "Svobodny Sokol" yingcweti ukukhiqizwa yezimboni isigaba esisha zokwenziwa esiyinhlanganisela isitokwe metal enegama commercial "Synthicom". Workpiece Mix impahla ekukhiqizeni Metallurgical sisetshenziselwa izinto i-iron nensimbi oxides, ukwakheka, properties kanye ukuziphatha esizayo isethwe at esiteji yokukhiqiza.

"Synthicom" ikhiqizwa ingulube yensimbi emamaki P1, P2 noma ingulube yensimbi Foundry futhi PL2 kanye oxidant (nsimbi zithutha Lebedinsk noma Michael GOKov) njengoba Castings mbhoshongo emise enesisindo 7-10 kg, ingots ezifanayo owawufanekiselwa insimbi.

neminye imikhiqizo

OAO "Lipetsk Metallurgical Plant" kuveza anhlobonhlobo imikhiqizo:

• Ukusakaza Shaped: cast iron kubhaklazeka ngoba ikhebula ngocingo futhi manholes; kocingo ngehele; yensimbi ukugaya amabhola. Zakamuva ezenziwe elimhlophe isakhiwo yensimbi-lukhuni futhi senzelwe ukugaya izinto ezahlukene ibhola Mills.
• Blast esithandweni kodaka. It is lisetshenziswe ukulahlwa Castings ngensimbi Foundries. Ngenxa yenqwaba encane kuqhuma esithandweni izitshalo kanye nempahla zanamuhla steelmakers baphonswa yensimbi Foundry kumaka L1-L6 quality eyanele.
• Nodular cast iron isetshenziswa ekwakheni Castings wemfanelo.
• Pig yensimbi iyadingeka ukuze kukhiqizwe Castings ezivamile.
• Nechobozekile kuqhuma esithandweni slag kukhishwa nezingxenyana ezithile 0-5 mm, 10-20 mm, 20-40 mm.
• Blast esithandweni slag mpilo: ingxenyenamba 40-250 mm.
• Coke ohelezayo: ingxenyenamba 0-10 mm, umlotha okuqukethwe hhayi ngaphezulu kuka-18%, umswakama ezingekho ngaphezu 24%.
• uthuli flue.
• Scrap 5A metal, 12A.

amathemba

Namuhla, "Svobodny Sokol" ihlangabezana ne nezikhathi ezinzima. Naphezu imikhiqizo eyingqayizivele ngesimo amapayipi ensimbi ductile, isitshalo empeleni ungeke uzithole usuwile. Nokho, inqubo ucabanga akusho kuvalwe ukukhiqizwa. Ngesikhathi bamasheya kanye nokuphatha uhlala isikhathi ukuqhuba ibhizinisi yokutakula. Ngiphakathi abakweletwayo noma iziphathimandla zedolobha ukumisa ukukhiqizwa sithakazelo.
