Maitiro Ekurapa Kupisa kwe431 Stainless Steel Forged Block

Kurapa kupisa kwe431 bhuroko rakagadzirwa nesimbi isina ngurakazhinji zvinosanganisira matanho matatu makuru:kunaya, kuomesa (kudzima)uyekudziyaDanho rega rega rine basa rakakosha mukuwana hunhu hwekupedzisira hwemakanika uye hunodzivirira ngura.

1. Kunyungudutsa - Kuderedza Kushushikana uye Kunyorovesa

KunyungudutsaInoitwa kunatsiridza chimiro chegorosi uye kuderedza kushushikana kwemukati kunoitika panguva yekuumba. Danho iri rinoita kuti chinhu chacho chive nyore kuchina uye rinoita kuti chive chakafanana chisati chaoma.

Maitiro Akajairika Ekuwedzera:

  • Kupisa Tembiricha:850–900°C

  • Nguva Yekubata:Zvakakwana kuti bhokisi rese risvike pakupisa

  • Kutonhodza:Kutonhodza zvishoma nezvishoma muchoto kudzivirira kukanganisa

Mabhenefiti eAnnealing:

  • Inoderedza kuomarara uye kuputsika

  • Inovandudza mashandiro emuchina uye kugona kushanda zvakanaka

  • Inoderedza kushushikana kwemukati kuti pave nekugadzikana kuri nani kwechimiro

Mushure mekunamirwa, chinhu chacho chinowanzova chakapfava uye chagadzirira kushandiswakugadzira nemazvo or matanho anotevera ekurapa kupisa.

2. Kuomesa (Kudzima) – Kuvandudza Simba Rakawanda

IyokuomaDanho ndiro danho rakakosha zvikuru kune431 bhuroko rakagadzirwa nesimbi isina ngura, sezvo ichichinja zvinhu kubva pachimiro che ductile kuitachikamu chemartensitic chakasimba kwazvo.

Magadzirirwo eKuomesa Maitiro:

  • Kupisa Tembiricha:980–1035°C

  • Nguva Yekubata:Yakareba zvakakwana kuti ikwanise kuomeswa zvachose (kazhinji maminetsi makumi matatu kusvika makumi matanhatu, zvichienderana nehukuru)

  • Nzira Yokudzimisa:Oiri kana mhepo, zvichienderana nekukora kwechikamu uye mwero wekutonhodza waunoda

Munguva yekupisa, chimiro chinoshanduka kubvaferrite to austeniteKana yatonhodzwa nekukurumidza (yadzimwa), austenite inoshanduka kuitamartensite, chimiro chakasimba uye chakasimba chakaita sekristaro.

Mhedzisiro yeKuomesa:

  • Simba reKusimba:Kusvika ku1300 MPa

  • Kuoma:260–300 HB (inogona kusvika ku40 HRC zvichienderana nekudziya kwemhepo)

  • Simba reKubereka:750–950 MPa

Zvinhu Zvikuru Zvekufunga nezvazvo:

  • Kudzima mhepo kunoderedza kukanganiswa kwemabhuroko makuru akagadzirwa.

  • Kudzima mafuta kunoita kuti zvive zvakaoma zvikuru kuzvikamu zvidiki.

  • Kudzora kwakakodzera kwekukurumidza kwekutonhora kwakakosha kudzivirira kutsemuka kana kupotoka.

Mushure mekuoma, chinhu chacho chinosimba zvakanyanya asi chinogonawo kupwanyika - ndosakakudziyaDanho rakakosha.

3. Kudzikamisa - Kuenzanisa Simba uye Kusimba

Magadzirirwo Ekugadzirisa Maitiro:

  • Kureba kweTembiricha:620–760°C

  • Nguva Yekubata:Maawa 1–2 zvichienderana nehukuru hwebhuroko

  • Kutonhodza:Kutonhodza kwemhepo

Migumisiro yeKudzikisa:

  • Inoderedza kushushikana kwemukati uye kuputsika

  • Inovandudzakuomauyekuramba kukanganiswa

  • Zvinowedzerakugadzikana kwehukurupanguva yebasa

  • Inobvumira kugadzirisa kuomarara zvichienderana nekushandiswa

Semuyenzaniso:

  • Tembiricha yakaderera (~620°C):Inoramba yakasimba uye yakasimba.

  • Kupisa kwakanyanya (~750°C):Inopa kusimba kuri nani uye ductility.
