Mafomu Ekurapa Kupisa eStainless Steel Forgings

1. Annealing

Chinangwa:

• Deredza kuoma uye kuvandudza ductility

• Bvisa kushushikana kwemukati

• Natsa chimiro chezviyo

Process:

• Kupisa kune imwe tembiricha (800-1100 ° C zvichienderana negiredhi)

• Bata kwenguva yakatarwa

• Kutonhorera zvishoma nezvishoma, kazhinji muchoto

Used For:

• Ferritic (430)uyemartensitic (410, 420)mamakisi

• Kupfava mushure mekushanda kunotonhora

• Kuvandudza machinability

sakysteelinopa inodzorwa annealing masevhisi kuti ave nechokwadi cheyunifomu microstructure uye yakakwana kupfava kwekugadzira.

2. Solution Annealing (Solution Treatment)

Chinangwa:

• Dissolve carbides uye precipitates

• Dzorera kusagadzikana kwekuora

• Wana homogeneous austenitic chimiro

Process:

• Kupisa kusvika ~1040–1120°C

• Kurumidza kudzima mumvura kana mumhepo kuomesa chimiro

Used For:

• Austenitic simbi isina tsvina(304, 316)

• Zvinokosha mushure mekugadzira kana kupisa kushanda

• Inobvisa chromium carbide precipitates uye inodzoreredza kusagadzikana kwekuora

sakysteelinova nechokwadi chekugadzirisa annealing inoteverwa nekukasira kudzimwa kudzivirira kukurudzirwa uye intergranular corrosion.

3. Kuomesa (Kudzima)

Chinangwa:

• Wedzera simba nekuoma

• Vandudza kusapfeka kupfeka

Process:

• Kupisa martensitic simbi dzisina tsvina kusvika ~950–1050°C

• Bata kuti austenitize chimiro

• Kurumidza kudzima mumafuta kana mumhepo

Used For:

• Martensitic Stainless simbi(410, 420, 440C)

• Zvikamu zvinoda kuomarara kwepamusoro (mavharuvhu, mabhengi)

Cherechedza: Austenitic steels haigoni kuomeswa nekurapa kwekupisa.

4. Tempering

Chinangwa:

• Deredza brittleness mushure mekuoma

• Wedzera kuoma

• Gadzirisa kuoma kune zvinodiwa zvekushandisa

Process:

• Kupisa kusvika 150-600 ° C mushure mekuoma

• Bata kwemaawa 1-2 zvichienderana nekukura kwechikamu

• Kutonhorera mumhepo yakanyarara

Used For:

• Martensitic Stainless simbi

• Kazhinji inosanganiswa nekuomesera mune nhanho mbiri

sakysteelinodzora kutenderera kutenderera chaiko kuti ienderane nemakanika maratidziro ebatch yega yega.

5. Kunaya Kuoma (Kuchembera)

Chinangwa:

• Simbisa kuburikidza nekugadzirwa kwakanaka kwemvura

• Wana simba regoho repamusoro pasina kukanganisa kwakanyanya

Process:

• Solution kubata pa ~ 1040 ° C uye kudzima

• Zera pa480–620°C kwemaawa akati wandei

Used For:

• 17-4PH (UNS S17400)uye alloys akafanana

• Aerospace, nyukireya, uye yakakwirira-simba zvikamu

Benefits:

• Yakanakisa simba-kune-uremu reshiyo

• Good corrosion resistance

• Kukanganiswa kudiki kana kuchienzaniswa nekuomeswa kwemartensitic

---

6. Kuderedza Stress

Chinangwa:

• Bvisa kushushikana kwemukati kunokonzerwa nemachining, forging, kana welding

• Dzivirira kuchinja kwedimensional panguva yebasa

Process:

• Kupisa kusvika 300-600°C

• Bata kwenguva yakati

• Kutonhorera zvishoma nezvishoma

Used For:

• Zvikamu zvakakura zvakaumbwa

• Precision-machine components

sakysteelinopa kushushikana kwetsika kudzoreredza mhinduro kuchengetedza dimensional kugadzikana kweakaoma forgings.

7. Normalizing (Ishoma musimbi isina simbi)

Chinangwa:

• Natsa saizi yezviyo

• Kuvandudza kufanana mukugadzirisa uye zvivakwa

Process:

• Kupisa kusvika pamusoro pekushandura tembiricha

• Mhepo inotonhorera kusvika kune tembiricha yekamuri

Used For:

• Inowanzo shandiswa mucarbon uye alloy simbi

• Dzimwe nguva inoshandiswa kune ferritic Stainless simbi

---

Zvinhu Zvinokonzera Kusarudzwa Kwekurapa Kupisa

• Stainless simbi giredhi

• Sevhisi tembiricha uye mamiriro

• Corrosion resistance zvinodiwa

• Inodiwa ma mechanical properties

• Saizi yechikamu uye chimiro

• Post-processing matanho (welding, machining)

Kurapa kwakakodzera kwekupisa kunovimbisa kuti simbi isina simbi forgings inoita zvakavimbika munzvimbo dzine hutsinye uye inosangana nemichina yemaitiro.

Kudzora Kwehutano Mukurapa Kupisa

At sakysteel, kupisa kupisa kwesimbi isina tsvina forgings kunoitwa mumavira anodzorwa ane:

• Yakarurama tembiricha monitoring

• Thermocouple kuteverakune zvimedu zvakakura

• Kutevedzera ASTM A276, A182, A564 zviyero

• Kuongororwa mushure mekurapakusanganisira kuoma, kusimba, uye metallographic kuongorora

• EN 10204 3.1 / 3.2 chitupapakukumbira

---

Zvishandiso zveHeat Yakabatwa Stainless Simbi Forgings

• Flanges uye Fittings: Solution annealed kana normalized

• Shafts uye Valve Zvikamu: Akaomeswa uye ane hasha

• Pombi Dzimba: Stress yapera

• Zvikamu zveAerospace: Kunaya kwakaoma

• Kumanikidza Midziyo: Yakakwenenzverwa uye yakaedzwa kune ASME zviyero

sakysteelinoshandira vatengi mukugadzira magetsi, marine, midziyo yechikafu, mafuta & gasi, nezvimwe.

Mhedziso

Kurapa kwekupisa inhanho yakakosha mukugadzirwa kweStainless simbi forgings, kubvumira kutonga kwakanyatso pamusoro pesimba remagetsi, kusagadzikana kwekuora, uye chimiro chemukati. Zvichienderana nealloy uye kushandiswa, kupisa kupisa kunogona kusanganisira annealing, kugadziriswa kwekugadzirisa, kuomesa, kupisa, kuderedza kushungurudzika, kana kuchembera.

Nokunzwisisakupisa mafomu ekurapa kwesimbi isina tsvina forgings, mainjiniya nevatengi vanogona kutsanangura maitiro akakodzera ezvikumbiro zvakakosha. Atsakysteel, isu tinopa yakakwana yekuforoma uye yekupisa masevhisi ekurapa ayo anoenderana nepasi rose zviyero uye zvakatemwa nevatengi.
