Re bolella seo constructional tšepe

Tšebeliso ea tšepe e telele e ho pharaletseng kene bophelong ba rōna 'me ha a etsa hore lipelaelo leha e le efe ka botleng ba eona. Empa ha rea lokela ho lebala hore tšepe e ka ba fapaneng. Kajeno ile a totobatsa 'maloa mefuta ea lintho tse bonahalang:

1. Mehaho tšepe.
2. Sesebelisoa tšepe.
3. Tšepe merero ea motho ka mong le thepa e khethehileng.

A re ke re bue kajeno ka steels le mehaho. Kahoo bitsoa mefuta eohle, tse sebelisitsoeng ka tlhahiso ea mehaho e haha, hammoho le likarolo tse ling tsa mechine le mekgwa.

mefuta ea lintho tse bonahalang

Mehaho tšepe e arotsoe ka lihlopha tse peli tse khōlō:

1. Boleng bo phahameng mehaho motsoako.
2. Boleng bo phahameng mehaho k'habone.

mefuta ena kaofela li sebelisoa ka sebaka ho khetheha ea tlhahiso, a phethang mesebetsi eo ba e abetsweng.

Mehaho alloyed tšepe

hangata ha ho ho ntlafatsa sebetsa ka, thepa 'meleng le lik'hemik'hale tsa matla a phaella ka ho re ho ea tšepe likarolo tse sa tšoaneng, ke hore, e doped. Ka kakaretso, tsena merero ea, chromium nikele, a mankanese a. Mehaho boleng tšepe ka 'na na le le leng kapa a' maloa likarolo tse joalo. Tabeng ena, ho ema ka ntle:

• Tlaase motsoako (nomoro ya ho sebelisoe ha se ho feta 2,5%).
• Srednelegirovannye (palo e ka tsoha ho 10%).
• Phahameng alloyed (likarolo tse eketsehileng etsang ho feta 10%).

E le hore re utloisise hore na ho sebetsa le ho tseloe, ha ho hlokahala hore ba utloisise ka bophara boitsebiso boo. E thehiloe ferrite (ka 90% ka bophahamo ba modumo). Likarolo alloying ba qhalwa ho ya ka ferrite, ka tsela eo ntlafatsa durability lona. Haholo-holo atlehang ka ho tabeng ena, ka silicon, nikele le mankanese. Empa chromium tungsten le molybdenum ba le phello e fokolang haholo.

Re lokela ho hlokomela hore mehaho motsoako tšepe fapane tlaase weldability. Sena ke ka lebaka la ho thatafatsa ea mocheso ameha libaka le sebopeho ka hare ho eona ba dibopeho tse senyehang habonolo. Ka lebaka leo, dithekeniki khethehileng li sebelisoa tshebetso tjheseletsa, ntshetswa pele le batho ka bomong ho mofuta ona wa tšepe.

Tlaase motsoako mehaho tšepe e sebelisoang ka bophara bathong bakeng sa tlhahiso ea locomotives, likariki le mechine fumanehang moo polasing. lihlahisoa tsena kaofela li tšoauoa ka bokhoni ba bona ba ho mamella mejaro polygonal. weldability entsprechen tsa tšepe ena u se ke ua ba le lithibelo leha e le efe.

Ho tloha phahameng-motsoako tšepe entse lehare le turbine rotors, reactors, liphaephe liphaephe mouoane ebe e manifolds.

K'habone mehaho Steel

The mofuta bobeli e tšoantšetsoang ke mefuta e seng mekae haholo, tse kang:

• Engineering. Mehaho tšepe ea mofuta ona e le sebelisitsoe ka tlhahisong ea likoloi.
• Automaton. Ke ka lebaka la tšepe ena etsa fasteners tse sa tšoaneng. Ho hang ha e loketse bakeng sa tjheseletsa, makolopetso 'ohle a sebetswa ka mechine ena.
• Boiler kamore. Bohlokoa haholo ho na le, moo ho tluoa tabeng ea ho tlhahisong ea litanka le lijana, eo na le ho mamella mocheso ho phahameng. tšepe ena e na le weldability molemo.

Mehaho tšepe - the tse bonahalang, ntle le e leng tlhahiso ea mefuta e itseng ea makala le dikarolo ke ke ha khoneha.
