Heat-resistant karfe turboproizvodstve. Main halaye na kayan

Heat resistant steels da kuma gami a matsayin musamman irin shiri kayan fara da za a yi amfani da quite a baje dangane da ci gaban da injin turbin yi masana'antu. Injin turbin a matsayin makamashi Madogararsa ko transducer amfani da thermal ikon kayan aiki, jirgin sama da kuma jirgin injuna. In mun gwada kwanan wata yaduwa daga cikin gas injin turbin zane ga ƙasa birgima stock (manyan motoci, locomotives).

Tare da karuwa a gas mashiga zazzabi an rage takamaiman man fetur amfani da naúrar iko. A wannan batun, a wani fairly gajeren lokaci akwai zafi-resistant karfe. Yau wadannan kayan a injin turbin kayayyaki ne up to 50% na jimlar nauyi.

Heat kãfira karfe ne kayan aiki ba kawai a dagagge yanayin zafi. Shi ne m, a cikin yanayin slozhnonapryazhennogo jihar qaddara lokaci lokaci. A farko halayyar cewa kayyade yi na ce abu ne high-zazzabi ƙarfi.

A karkashin wannan quality bai fahimci haddasawa kai ga lalata wani ba nakasawa danniya wanda yake iya goyon bayan karfe abu a wani musamman zane a wata ba yawan zafin jiki ga wani takamaiman lokaci lokaci. Lokacin da aka shimfiɗa lokaci da kuma irin ƙarfin lantarki, da halayyar kira tensile ƙarfin (tsawon lokaci). Idan aka ƙaddara nakasawa, lokaci da danniya, da ingancin aka kira creep ƙarfi.

Heat-resistant steels da, baicin ƙarfi, ductility, wanda dole ne a kiyaye har karshen aiki. A cikin sharuddan plasticity reserves an kiyasta AMINCI daga karfe aiki.

A muhimmanci halayyar da abu ne mafi daraja ji na ƙwarai. Wannan ingancin aka ƙaddara a cikin nau'i na dangantakar elapsed lokaci har da gazawar da santsi da kuma zira kwallon samfurori gwada a wannan zafin jiki gajiyan. Heat resistant steels dauke m daraja a wani rabo daidai ko mafi girma daga hadin kai.

Saboda gaskiya cewa Yunƙurin zuwa zafin aiki ya auku a kan lokaci, cikinsa da aiki yayi dace da farko, yawanci wani yanayi zazzabi, mai girma hankali ne ya biya zuwa dabi'u na elasticity da kuma ƙarfi. Yana da muhimmanci cewa dabi'u gudanar da kaya a dakin da zazzabi kasance high isa.

Saboda gaskiya cewa da zafi resistant steels slozhnonapryazhennogo sarrafa karkashin wani yanayin wanda aka halin m canji a cikin alamar da kuma girma na kaya, ba tare da muhimmanci da kuma wani babban gajiya juriya.

Yau da yin amfani da rikitarwa fasaha mafita ga halittar Tsarin wajabta da karfe kayan da ciwon high fasaha halaye. Saboda haka, a cikin yi da ruwan wukake a gas injin turbin injuna amfani ƙirƙirãwa, daidaici Forging, polishing, inji aiki hanya da kuma gama articles sandunansu, daidaici simintin, polishing. Production na konewa bẽnãye zafi-resistant karfe zanen gado da aka yi amfani da wani m, sanyi kafa, tabo waldi da sauran kimiyoyi. Mafi na kowa dabaru ake waldi lantarki gogayya yadawa bonding, brazing kayayyakin. Duk wadannan jan bukatar high quality halaye na kayan amfani.

Superalloys da karfe inherently iya rike ƙara ƙarfin Manuniya kamar yadda ga ma'aikatan da kuma aiwatar da yanayin zafi. Wannan, bi da bi, ya dora wani takamaiman lamba a kan dukan karfe redistribution fasahar amfani, tare da nakasawa da ingot da kuma kafin a karshe karewa ayyukan, kayayyakin da ake bukata surface smoothness kuma so girma.
