Chimwe chinyorwa chekunzwisisa vacuum high pressure gas quenching furnace

1. Chii chinonzi vacuum high pressure gasi quenching?

Vacuum high pressure gasi quenching inoreva simbi yekushandisa, high-speed simbi uye alloy simbi zviri nyore kuomesa zvinhu. Mushure mekuiswa muchoto chevacuum kuti usvike padhigirii rekutsvaira rakatsanangurwa nemaitiro, inopisa kune yakaoma tembiricha Ac3 kana Ac1 kana pamusoro, uye inochengetwa ichidziya zvinoenderana nezvinodiwa maitiro. Kwenguva yenguva, wobva wazadza yakakwira-kudzvanya inert gasi (Iye, Ar) kana isiri-reactive gasi N2 kana imwe gasi yakasanganiswa, mukamuri inosvika pakumanikidzwa kwakataurwa (10bar, 20bar, 40bar), uye panguva imwe chete. batidza feni ine simba guru kuti utyaire feni inodzivirira kupisa. Iyo inopisa workpiece inoputirwa nekumhanya kukuru. Mushure mekunge mhepo inopisa inoyerera ichipfuura nepakati yakasarudzika yekupisa yekutsinhana uye kutonhora, iyo inotonhora inoyerera inonatsa iyo workpiece zvakare, uye pakupedzisira kupisa kwekupisa kwemartensitic quenching chimiro kunowanikwa.

Schematic dhizaini yekudzima tembiricha yemhando yesimbi

2. Kushandiswa kwevacuum high pressure gasi inodzima muchoto Tool Simbi, Die Steel, High Speed ​​Steel, Ultra High Strength Simbi.

3.Kushandiswa kwevacuum high pressure gas quenching furnace

• 300M simbi, gasi kudzima pasi pe10bar N₂:

Zvinogona kuonekwa kubva pamufananidzo kuti kuomarara kweF60 round bar kwasvika pakudzima mafuta (kazhinji anenge 53HRC), uye core is a lath martensite structure ine good hardability. Iyo Ф80 kutenderera bhaa haizadzise zvinodiwa pamusoro apa. Izvi zvinoratidza kuti dhigirii yekuomeswa kweiyo workpiece inobatwa nekuoma kwekugona kwemidziyo.

• 8Cr4Mo4V simbi, gasi kudzima pasi pe0.2MPa N₂:

Miedzo mhinduro ye8Cr4Mo4V simbi roller inotakura D10 XX /01 pasi pegasi / mafuta ekudzima maitiro

Kudzima zvinodiwa: kuoma 60 ~ 64HRC; sangano M2 ~ M4; deformation (cylindrical, flatness) inofanira kudzorwa pakati pe 0.20mm.

Kana iyo kuomarara uye microstructure inosangana nezviyero, iyo isingakodzeri mitengo yekutenderera uye flatness yegasi rakadzimwa workpiece iri 20% uye 10%, zvichiteerana, nepo iyo yemafuta akadzima workpiece ari 70% uye 70%. Zvinogona kuonekwa kuti kudzima gasi kunogona kuderedza zvakanyanya deformation ye workpiece.

4. Zvakanakira vacuum high pressure gasi quenching

• Hunhu hwepamusoro hweiyo workpiece yakanaka, hapana oxidation, hapana kuwedzera kabhoni, uye hapana alloying element depletion.

• Iko kudzima kufanana kwakanaka, uye deformation ye workpiece idiki.

• Kumhanya kwekutonhora kunodzoreka. Iko kutonhora kwekumhanya kunodzorwa nekushandura inflation pressure uye airflow direction, uye fan speed (frequency conversion). Nenzira yakanaka, inogona kuva pedyo ne isothermal quenching.

• Iyo yese muitiro haina kusvibiswa uye haina tsvina gasi emission, uye gasi rakadzimwa workpiece haidi kucheneswa kwechipiri, iyo inoshanda, inochengetedza simba uye ine ushamwari kwezvakatipoteredza.

5. Izvo zvikuru zvinopesvedzera zvinhu zvekudzima mhedzisiro yeyakanyanya kumanikidza gasi kudzima choto.

6. Zvinhu zvikuru zvinokanganisa chiyero chekutonhora che workpiece

7.Zvinhu zvikuru zvinokanganisa kudzika kwekudzika kwe workpiece

◆ Iyo gasi inodzimisa kudzvinyirira haingoiti chete kutonhora kweyero ye workpiece, asiwo inokanganisa kuoma kwayo, saka inofanira kusarudzwa zvakanyatsonaka.

8, ACME Vacuum Mhepo Inodzima Furnace

Vertical pazasi kuchaja vacuum mhepo inodzima choto

Tekinoroji maitiro e ACME yakatwasuka pazasi kuchaja vacuum mhepo inodzima choto:

• Muviri wechoto wakamira, imwe-chamber, pasi-loading, kunyanya yakakodzera kune yakareba tsvimbo-yakaita workpieces.

• Iyo yepasi pechoto chegonhi inosimudza nzira yekufambisa inotora bhora screw, iyo inofamba mumutsara wakatwasuka, isiri nyore kunamira, uye ine chivharo chekudzivirira kudzivirira kusvibiswa kweguruva.

• Iyo dhizaini-inoshandura kutonhora tekinoroji inogona kushandiswa kune ese ari maviri longitudinal pfapfaidzo kutonhora uye 360 ​​° circumferential kutonhora.

• Iyo bracket yekusimudza yakashongedzerwa ine otomatiki chiyero chekugadzirisa masisitimu, iyo inobvisa otomatiki kukanganisa kwekuwedzera kweiyo yekusimudza system. Kusimudza kwakadzikama uye hapana kuzunguzika.

Horizontal vacuum high pressure gasi inodzima vira

Tekinoroji maitiro e ACME horizontal vacuum yakakwira kumanikidza gasi kudzima choto:

• Iyo liner yevira inogadzirwa modularly, uye kufanana kwetembiricha yechoto uye kutonhora kwakafanana zvese zvakanaka.

• Zvichienderana neakasiyana ekutonhora kutonhora zvinodiwa zvezvikamu, imwe chete yekupisa yekupisa uye maviri-nhanho kana kunyange yakawanda-nhanho yekupisa yekupisa yevira yekupisa chimiro inogona kusarudzwa.

• Kune izvo chaizvo zvekugadzirisa zvikamu, iyo yekumashure yekusveta gasi inodzima kutenderera system kana yekumberi yekusveta gasi inodzima kutenderera system inogona kusarudzwa.

• Yakasiyana-siyana-matanho maviri ekupisa kupisa, nzvimbo yekutsinhanisa kupisa inopetwa kaviri kana ichienzaniswa neyakajairika.

Unyanzvi Zvimiro zve ACME Gasi Kudzima Furnace

◆Circular thermal field structure: Iyo nozzle type inogona kuronga akawanda ma nozzles akatenderedza kamuri yekudziya pa 360 °, kuitira kuti mhepo inofefeterwa kune workpiece mumativi ese kuti iwane kutonhora kwakafanana, uye sisitimu ine chimiro chakareruka uye ndiyo inonyanya kushandiswa. .

◆Square thermal field structure: Iyo yakanyanya-kumhanya inotonhora mweya inopfurwa kune workpiece kuburikidza nemuromo wemhepo yekuparadzira ndiro, uye mweya unopisa unoburitswa kuburikidza nendiro yekugovera. Mushure mekuchinjana kupisa kuburikidza nemuchinjisa wekupisa, mweya wekudzoka unotenderera uchitevedza pombi uye unovhuvhuta uchienda kunzvimbo yekushanda kuti uwane kutonhora kwe isothermal. Yapera process.

◆Katatu kutonhora maitiro (ACME patented tekinoroji): Yakasarudzika yekumashure yekudzoka mhepo yekuyerera tekinoroji, katatu kutonhora basa, kumberi uye kumashure maviri maviri ekupisa kupisa kuchinjika, zvirinani kuita.
