OJSC "Lipetsk Metallurgical Cog "Svobodny Sokol" yog lub tuam txhab qub tshaj plaws hauv nroog Lipetsk, uas tau ua kev zoo siab rau ib puas xyoo ntawm keeb kwm. Kev tsim tshwj xeeb hauv cov khoom tshwj xeeb rau Russia - high-strength cam khwb cia hlau dej siab kav.

keeb kwm keeb kwm

Lipetsk Metallurgical Cog tau tsim nyob rau xyoo 1899 los ntawm Belgian ua lag luam. Txij li thaum cov chaw tsim khoom nyob rau hauv lub zos ntawm Sokolsk, uas tom qab ntawd los ua ib feem ntawm lub nroog txwv Lipetsk, lub enterprise hu ua Sokolsky Metallurgical Cog. Lub tuam txhab tau mus txog nws lub peev xwm tag nrho hauv 1900 tom qab tso tawm ob lub qhov cub tawg.

Nyob rau hauv lub sijhawm Soviet, cov khoom tau hloov npe hu ua Lipetsk Metallurgical Cog Svobodny Sokol. Tau ntau xyoo, lub tuam txhab tau tsim cov khoom lag luam zoo cam khwb cia hlau. Txij xyoo 1934, lub koom haum tau hloov mus rau kev tsim cov kav dej cam khwb cia hlau.

Iron production

Hnub no, Lipetsk Metallurgical Cog suav nrog 14kev tsim tawm. Cov khoom tseem ceeb yog blast-kuav thiab cov yeeb nkab foundries. Lub khw muag khoom hluav taws xob muaj ob lub qhov cub nrog lub peev xwm ntawm 700 m 3txhua tus nrog cov txheej txheem ntawm lub raj mis thiab cov cuab yeej pabcuam. Lawv muab tso tawm cov kua thiab npua hlau. Lub rooj cob qhia tsim cov khoom tsim thiab qhov kawg hlau ntawm ntau pawg.

Vim qhov ntim me me ntawm qhov cub tawg, metallurgists muaj peev xwm smelt zoo heev hlau nyob rau hauv ib tug ntau npaum li cas, txawm nyob rau hauv me me batch. Lub tshuab casting ua rau nws muaj peev xwm ua tiav cov hlau zoo tshaj plaws, cov qauv uas yog cov yam ntxwv ntawm cov khoom siv ruaj khov, tsis muaj cov cementite dawb hauv microstructure, tsawg heev nyiam ntug sib cais thiab zoo heev machinability. cam khwb cia hlau yog tsim nyob rau hauv ingots txog li 9 kg, lawv yooj yim thauj nyob rau hauv tej nyob rau hauv freight rail tsheb.

Pib ntau lawm

Nyob rau hauv 1990, nyob rau hauv ua ntej ntawm lub cev qhuav dej ntawm lub USSR, ib tug yeeb nkab foundry nruab nrog niaj hnub khoom raug commissioned nyob rau hauv lub Lipetsk Metallurgical Cog rau zus tau tej cov high-strength cam khwb cia hlau dej siab kav, nyob rau hauv cov qauv ntawm uas. graphite yog nyob rau hauv ib tug kheej kheej (spherical) lub xeev. Cov khoom siv no sib xyaw cov khoom tshwj xeeb - cov khoom siv zoo ntawm cov hlau thiab corrosion kuj ntawm cam khwb cia hlau:

• siab elongation;
• cuam tshuam;
• tensile zog;
• plasticity.

Cov khoom no tau txais los ntawm kev hloov kho cov xim grey cam khwb cia hlau nrog magnesium. Hloov graphite hais nyob rau hauv high-lub zogcov khoom yog nyob rau hauv daim ntawv ntawm microscopic spheres-pob. Lawv tshem tawm qhov tsim thiab nthuav tawm ntawm cov kab nrib pleb, muab cov hlau nrum hardness thiab ductility.

zoo li castings

Lipetsk Metallurgical cog mastered serial ntau lawm:

• Dej txias tub yees daim hlau rau blast furnace cooling device. Lawv tau ua los ntawm cov hlau tsis tshua muaj chromium cam khwb cia hlau hauv ntau qhov ntau thiab tsawg los ntawm 1.58 txog 2.9 tons.
• Chutes rau npua hlau, nrog rau cov slag los ntawm lub qhov cub tawg.
• Castings los ntawm cam khwb cia hlau qib SCH-15, SCH-20 nrog qhov ntev 3x1, 2x1 m thiab qhov hnyav tshaj plaws ntawm 3.5 tons.
• Castings los ntawm aluminium alloys txog li 8 kg.

Cov nroj tsuag npaj los tsim cov khoom lag luam rau cov khoom ntim hauv qab ntawm lub tshuab hluav taws xob cua sov cua sov (hauv qab ntim grate, txhawb txhua kab).

Synticom

Svobodny Sokol cog tau paub txog kev tsim khoom lag luam ntawm chav kawm tshiab ntawm cov khoom siv hlau sib txuas nrog lub npe lag luam Sintik. Tus nqi billet rau metallurgical ntau lawm yog ib yam khoom uas muaj cam khwb cia hlau thiab hlau oxides, muaj pes tsawg leeg, zog thiab yav tom ntej tus cwj pwm uas yog teem nyob rau hauv lub manufacturing theem.

Sintikom yog tsim los ntawm npua hlau qib P1, P2 los yog foundry npua hlau PL2 thiab tus neeg sawv cev oxidizing (hlau pellets los ntawm Lebedinsky los yog Mikhailovsky GOKs) nyob rau hauv daim ntawv ntawm pyramidal castings hnyav 7-10 kg, zoo ib yam li cov hlau ingots..

Lwm yam khoom

JSC "Lipetsk Metallurgical Cog" ua ntau yam khoom:

• Zoo li casting: cam khwb cia hlau manholes rau cable xov tooj thiab manholes; laj kab gratings; sib tsoo hlau pob. Cov tom kawg yog ua los ntawm cov hlau cam khwb cia dawb nrog cov qauv perlite-cementite thiab yog tsim los rau kev sib tsoo ntau yam khoom hauv pob zeb.
• Blast furnace sludge. Nws yog siv nyob rau hauv castings nyob rau hauv hlau foundries. Vim lub ntim me me ntawm cov nroj tsuag tawg rauv thiab cov khoom siv niaj hnub no, metallurgists tau txais cov cam khwb cia hlau qib L1-L6 ntawm cov khoom zoo txaus.
• Nodular cam khwb cia hlau yog siv los tsim cov khoom tseem ceeb.
• Npua hlau yog xav tau rau kev tsim cov pa roj hmab.
• Crushed moj tej tawg-kuav slag feem: 0-5 mm, 10-20 mm, 20-40 mm.
• Dump moj tej tawg-kuav slag: feem 40-250 mm.
• Coke cua: feem 0-10 hli, cov hmoov tshauv tsis tshaj 18%, av noo tsis tshaj 24%.
• Flare plua plav.
• Qab hlau 5A, 12A.

Prospects

Hnub no "Free Falcon" tab tom dhau lub sijhawm nyuaj. Txawm hais tias cov khoom tshwj xeeb nyob rau hauv daim ntawv ntawm cov kav hlau kav, cov nroj tsuag tau poob nyiaj tiag tiag. Txawm li cas los xij, cov txheej txheem kev lag luam poob tsis tas txhais tau tias yog kaw ntawm kev tsim khoom. Cov tswv lag luam thiab cov thawj coj muaj sijhawm los siv rau kev txhim kho kev lag luam. Tsis yog cov neeg qiv nyiaj lossis cov tub ceev xwm hauv nroog tsis txaus siab txwv kev tsim khoom.
