PJSC "Nadezhda Metallurgical Cog" yog ntawm kaum sab saum toj cov neeg tsim khoom ntawm cov hlau dov. Ntxiv nrog rau cov hlau, lub tuam txhab tsim cov hlau cam khwb cia, tsim cov pob zeb thiab cov pob zeb ua vaj tse. NMZ nyob rau sab qaum teb ntawm cheeb tsam Sverdlovsk, hauv nroog Serov.

Creation

Lub Urals tau yog qhov tseem ceeb tshaj plaws kev lag luam mining thiab chaw lag luam ntawm Russia txij li lub sijhawm Peter I. Tom qab kev tsim kho ntawm Trans-Siberian Railway nyob rau hauv lub xyoo pua 19th, lub cheeb tsam tau txais cua thib ob. Nws tau dhau los ua kev tsim kho kev lag luam hauv thaj chaw tshiab, kev txhim kho uas yav dhau los cuam tshuam los ntawm kev thauj mus tsis tau.

Tom qab kev tsim kho ntawm txoj kev tsheb ciav hlau nyob rau hauv ib qho chaw deb ntawm Urals, kev tsim kho ntawm cov cog hlau loj loj tau pib. Kev tso ntawm lub lag luam tau tshwm sim rau lub Tsib Hlis 29, 1894. Tom qab 19 lub hlis, thawj cov hlau tau smelted, me ntsis tom qab ntawd lawv pib tsim cov tsheb ciav hlau.

Cov nroj tsuag tau txais lub npe poetic Nadezhdinsky nyob rau hauv kev hwm ntawm tus poj niam ntawm tus tswv ntawm lub tuam txhab A. A. Polovtsova - Nadezhda Mikhailovna. Nws yog qhov loj tshaj plaws metallurgical ntau lawm hauv Urals. Cov khoom siv los ntawm cov tuam txhab zoo tshaj plaws hauv Belgium, Fabkis thiab lub teb chaws Yelemees. Los ntawm 1913, ib feem tsib ntawm tag nrho cov Ural hlau tau smelted nyob rau hauv nws phab ntsa.

Kev txhim kho

Lub kiv puag ncig thiab kev ua tsov rog ntshav tshwm sim tsis tau cuam tshuam kev ua haujlwm ntawm Nadezhda Metallurgical Cog. Txog rau xyoo 1931, lub hauv paus ntawm kev tsim khoom yog tag nrho tib txoj hlua, ntu thiab vov tsev hlau, cov ntaub ntawv refractory, blanks rau mos txwv.

Txij li xyoo 1931, qhov profile ntawm NMZ tau hloov pauv ntau heev. Tsoomfwv tau qhia kom npaj cov khoom lag luam zoo tshaj plaws thiab cov khoom siv dov ntawm ntau ntu, yog li tsim nyog rau kev lag luam hauv tebchaws Soviet. Xyoo 1933, lub khw muag khoom loj tau qhib, uas cov khoom dov tau ua los ntawm kev kos duab txias, ua raws li kev tig thiab sib tsoo.

Thaum tsov rog, kev cia siab tshwj xeeb tau pinned ntawm Nadezhda Metallurgical Cog (Serov). Nws yog ib qho ntawm ob peb tus neeg xa khoom ntawm cov hlau zoo thiab cov khoom dov ntawm ntau tshaj li ib puas qib. Ntawm no mastered txoj kev alloying nrog titanium, nickel, vanadium, chromium, molybdenum. Xyoo 1946, cov neeg ua haujlwm hauv lub Hoobkas tau txais qhov khoom plig zoo - Qhov Kev Txiav Txim Siab ntawm Kev Ua Haujlwm Liab.

Ua raws li kaum xyoo, kev tsim khoom tau tsim kho tsis tu ncua. Kev tsim khoom lag luam, kev ua haujlwm kab lis kev cai tau nce, vaj tse thiab kev tsim vaj tsev tau tsim, kev sib raug zoo thiab kev coj noj coj ua tau ua tiav. Xyoo 1975, kev tsim cov pas nrig rau cov twj (submersible thiab roj) tau pib.

Newstage

Lub Nadezhda Metallurgical Plant tau ntsib nws thib ob yug los ua ib feem ntawm Ural Mining thiab Metallurgical Company. Rau 16 xyoo, lub tuam txhab tau dhau los ua qhov kev tsim kho loj, uas yog raws li kev hloov pauv los ntawm kev qhib-hearth mus rau hluav taws xob steelmaking.

Hluav taws xob steel-smelting complex muaj EAF-80, tawm ntawm lub cub tawg steel ua chav tsev (ntev rauv thiab lub tshuab nqus tsev degasser) thiab lwm yam khoom siv pabcuam muab ntau tshaj 500,000 tons ntawm cov hlau txhua xyoo. Lub sijhawm no, kev tsim khoom ntawm 328 qib hlau tau ua tiav.

Ua tsaug rau kev ua haujlwm nqus, qhov ntsuas zoo ntawm cov hlau xa mus rau lub tshuab tsim thiab kev lag luam tsheb tau nce. Tsis tas li ntawd, Nadezhda Metallurgical Plant rov tsim cov pob bearing steel nrog lav zoo. Muaj ntau yam khoom (tshaj li 400 hom), Nadezhda Metallurgical Cog txhua xyoo replenishes nws nrog tshiab profile qhov ntau thiab tsawg ntawm cov khoom dov ntawm seem mills 850, 450 thiab 320. Nyob rau theem ntawm sizing ntau lawm, calibrated dov cov khoom nrog txhim kho machining zog rau kev lag luam tsheb yog tsim.

Tshaj li 7 xyoo dhau los NMZ tau paub txog 19 qhov tshiab dov profile. Los ntawm 2014, qhov ntim ntawm kev tsim cov khoom lag luam tshiab tau nce mus txog 80,000 tons, uas yog 16% ntawm tag nrho cov ntim ntawm cov hlau uas tau muag rau xyoo.

Kev piav qhia

Nyob rau xyoo 2016, lub tuam txhab ua kev zoo siab rau nws 120th hnub tseem ceeb. Tom qab ib puas xyoo, ob peb tiam ntawm cov kws tshaj lij tau hloov pauv, cov cuab yeej tsim khoom tau hloov kho, thiab cov khoom lag luam tau nthuav dav heev. Today PAONMZ yog ib feem tseem ceeb ntawm UMMC tuav.

Cov nroj tsuag ua haujlwm ntawm cov thev naus laus zis ntawm kev ua tiav metallurgical. Rolled steel yog tsim ntawm no:

• carbon raws li GOST 1050-88;
• alloyed raws li GOST 4543-71;
• pob bearing raws li GOST 801-78;
• automatic raws li GOST 1414-75.

Tag nrho 328 stamps. Kev tsim khoom ntawm Nadezhda Metallurgical Cog yog 550,000 tons ntawm calibrated steel thiab dov hlau.

Cov khoom tso tawm yog tsom rau kev lag luam hauv tsev. Ntawm qhov zoo ntawm kev ua haujlwm yog qhov ua tau ntawm kev xaj me me-tonnage batches ntawm cov khoom siv hlau dov, kev tsim khoom thiab xa khoom uas tau ua tiav hauv lub sijhawm luv luv.

Production

Txoj haujlwm muaj zog tshaj plaws ntawm Nadezhda Metallurgical Cog yog nyob rau hauv calibration steel sector, qhov twg lub tuam txhab tuav 2-3 txoj haujlwm ntawm Lavxias teb sab manufacturers. Hauv cov khoom lag luam ntev, NMZ tau nyob hauv TOP-10 ntawm cov neeg tsim khoom hauv tsev tau ntau xyoo. Thiab qhov no yog txawm tias lub siab ntawm cov loj loj xws li Mechel, MMK, Severstal thiab lwm yam nroj tsuag loj.

Cov nroj tsuag tau paub txog kev smelting ntawm ib hom hlau tsis tshua muaj - hollow drilling. Ib txhia ntawm nws yog exported. Nyob rau hauv cov kev taw qhia no, lub tuam txhab occupies ib tug thawj coj. Nyob rau hauv lub sector ntawm cov yeeb nkab blanks, muaj ib tug metallurgical nroj tsuag npe tom qab. A. K. Serov yog qhov tsis tseem ceeb - txog 1% ntawm kev ua lag luam. Txawm li cas los xij, NMZ muaj kev lag luam muag khoom ruaj khov, muab cov yeeb nkab blanks rau tus khub ntev, OJSC PNTZ.

khoom

Metallurgical cog lawv. A. K. Serova nqa tawm ntau lawm:

• dov cov khoom nrog tshwj xeeb nto tiav;
• rolled gauge (hexagonal, round);
• yob bar (hexagonal, square, round);
• npua hlau;
• hlau vitriol;
• ntau qhov khoob (pipe, axial).

Dhau li ntawm, NMZ muaj ntau yam khoom siv ntxiv dag zog:

• puab kab teeb, txhawb nqa;
• phab ntsa thaiv rau hauv qab daus, sab hauv tsev thiab sab nraum zoov;
• flights of stairs, parapet slabs;
• pem teb panels;
• laj kab slabs thiab posts, tiaj tus slabs;
• driven pawg.

Modernization

Txhawm rau kom muaj kev sib tw, kev tswj hwm ntawm UMMC tuav tau ua tiav ib ntus rov tsim kho ntawm PJSC NMZ. Ib qho hlau-smelting arc 80-tuj hluav taws xob rauv tau muab tso rau hauv kev ua haujlwm. Nrog rau kev siv zog ntau lawm, hluav taws xob steelmaking tshuab tau txais txiaj ntsig ntau dua.

Ib lub chaw kho dej, chaw tu roj, cov chaw siv hluav taws xob kuj tau tsim, thiab lub tshuab nqus tsev Italian tau muab tso rau hauv kev ua haujlwm. Lub tuam tsev tshiab tau qhib, qhov twg ferroalloys tau npaj. Launched argon thaiv. Ib qho kev ua tiav tseem ceeb yog qhov pib ntawm lub khw oxygen. Cov cuab yeej siv ntawm lub tuam txhab Italian SIAD tso cai tsim 5100 m3 ntawm oxygen ib teev 3oxygen.

Cov cuab yeej tau txais tshiab ua kom yooj yim duantau lawm, ho upgrade the assortment, rebuild the technological capacities in raws li kev ua lag luam. Tam sim no, mus txog 30 melts ntawm hlau yog nqa tawm ntawm NMZ ib hnub.
