He aha ngā āhuatanga kua legiruemye parahi?

Kei te mohiotia te reira e konganuku ki te whakaaro ma tiketike (99.99 ōrau ranei taonga parakore atu) i iti te kaha, te uaua ratou ki te whakamahi i. Okotahi e konumohe, me te parahi, kua whakamahia i roto i te engineering hiko. Steel, i roto i te hononga ki to ratou taumahinga, me riro rigidity, kakahu resistance, pakeke, me i roto i ētahi wā, elasticity me te kōngohe, heoi te rino i roto i te puka parakore ki te waihanga ratou kāore.

Legiruemye maitai rerekē i noa aroaro tāpiritanga āwenewene whakaurua e whakatau etahi āhuatanga o te koranu o te heke mai. Ko te kupu, i roto i te mau maitai waro i roto i roto i ngā hanganga "witi" ferrite, cementite, me Onemata. Ki te whakataki o nga mea timatanga alloying tau waro maha heke i roto i te pearlite (faarahi kaha maitai).

Legiruemye maitai i te whakauru maha whai matū atu te faahuru ê ripekapeka karaihe, e kia whakarato pokey atu (i roto i huri Onemata witi me te ferrite), he hekenga i roto i te ahotea ā, tūponotanga iti o hangai i roto i pakeke hua i roto i te hohonu o te rauemi me te calcining al ranei.

Ko te āhuatanga o kowiri tira e tika ti'aturi i runga i ngā wāhanga atu. Hei tauira, te chromium ngā huānga me te konukōreko anake wahi maitai i te waikura, faarahi konupora pānga ātete, kakahu piki resistance me te pakeke. Taua te huānga pērā i silicon, ka taea e tuhinga ki te tu pai pānga waikawa me whakanuia ana konukurahina te kaha nui-pāmahana.

Kei te wehea Legiruemye hanganga maitai matū ki teitei, ähua tata me iti-koranu (te ihirangi o tāpiritanga he neke atu i te 10%, 2.5 - 10% me te iti iho i te 2.5% anō). I roto i te pehu hua maitai srednelegirovannye (tāpiritanga Kei roto e pā ana ki 5-6%) o te hanganga pearlite. He iti noa te tahi atu alloys hanganga o te hanganga (martensitic, carbide, austenitic, ferritic).

Hoki ngā rauemi o tenei momo, kia rite ki te pai kia rite ki hoki ētahi atu hua ahumahi, he ona ake GOST. E whakarōpūtia e paerewa kāwanatanga koranu steels № 4543 - 71, i nei e taea te kite i tetahi te maha o ngā wāhanga atu i roto i te maitai o te ngā waitohu. Hei tauira, koranu hromomargantsovonikelevy ki Titanium me molybdenum 25HGNMT tauira tito te o runga ki te 0,29% waro, ki runga ki te 0.37% silicon, ki runga ki te 0.8 ōrau konupora, ki runga ki te 0.6%, me te 1.10% o chromium me te konukōreko (aua ), ki runga ki te molybdenum hawhe ōrau me 0,09 ōrau Titanium. I tua atu ki te whakaritenga Whārangi me hangarau GOST kei raraunga tonu i runga i ngā tikanga whakamātau hua, ture whakaaetanga, waka, tākai me etahi atu.

Kua wehea Legiruemye ano ki te maha o ngā rōpū rite ki o ratou whakaaro: hanga, taputapu (o e kawe tapahi taputapu pērā i ngā akoako, ngā kōnae, kani, kaitarai mira, me ētahi atu (E whakamahia i roto i te engineering aunoa, hanga o piriti, waka tereina, te hinu me te hau, puna, puna, etc..) .) me-whakaaro motuhake maitai he ātete nui ki te waikura o te iahiko momo.
