Mng’anjo yapakati yapakati pa induction sintering

1, kapangidwe ka zida

The ng’anjo ya sintering yapakati pafupipafupi makamaka amapangidwa thyristor wapakatikati pafupipafupi mphamvu magetsi, ndi ng’anjo haidrojeni sintering ndi basi dongosolo kutentha kulamulira. Kapangidwe ka gawo lililonse ndi motere:

1. The thyristor intermediate frequency power supply imakhala ndi KGPS-250/2.5 250KW 2.5KHz kabati yamagetsi, kabati yamagetsi yotenthetsera capacitor, kulumikiza mipiringidzo yamkuwa ndi makina a injini;

2. Ng’anjo yowotchera imapangidwa ndi thupi la thanki, inductor, alumina, zirconia refractory pot, tungsten crucible pot, thanki yamadzi yotseguka, hydrogen / nitrogen flow control valve control board, ndi gantry;

3. Makina owongolera kutentha amalimbikitsa njira izi:

4.1, makina owongolera kutentha amayezedwa ndi optical fiber sensor, yoyendetsedwa ndi chowongolera kutentha, ndikujambulidwa ndi chojambulira.

2, chachikulu luso zizindikiro kusankha njira ya sing’anga pafupipafupi kupatsidwa ulemu sintering ng’anjo

1 , m’mimba mwake: φ 400 × 750 × 16

2, zinthu zamkati: tungsten

3, kutentha kwambiri sintering: osachepera 2200 °C

4, kutentha kulamulira molondola: ± 10 °C

5, magetsi voteji: 380V, 50Hz, atatu gawo anayi waya dongosolo

6, pafupipafupi ntchito: 2500Hz

7, kuyeza kwa kutentha kwadzidzidzi, kuwonetsera, kujambula kokha

8. Kutetezedwa kwa ng’anjo ya haidrojeni, kutulutsa kosinthika koyenda, kutulutsa kwa slag

9, ndi overcurrent, overpressure, kusowa kwa gawo, kusakwanira kwa madzi, kutetezedwa kwa kutentha

10, kuchuluka kwa zida 1

4 , kufotokozera kamangidwe ka ng’anjo ya sintering

Doko loletsa kuphulika: nembanemba wosaphulika, gasket ya mphira ya silikoni ndi chotulutsa cha hydrogen chopondereza kwambiri.

Doko loyeserera lophulika: kuzindikira chotulutsa cha hydrogen mu ng’anjo.

Ng’anjo yamoto: zigawo ziwiri mkati ndi kunja, wosanjikiza wakunja ndi welded ndi 10mm wandiweyani 16Mn kuwotcherera zakuthupi. 8mm wandiweyani wosanjikiza wamkati ndi welded 1Cr18Ni9Ti, kuchuluka kulimbikitsa mipiringidzo, kupewa kwambiri madzi kuthamanga ng’anjo wamoto cholumikizira zigawo mkati ndi kunja, pakati ndi pansi.

Chophimba cha ng’anjo: kapangidwe kake ndi kofanana ndi thupi la ng’anjo.

Chophimba cha lens: Chingwe chozungulira chimamangidwa kuti chiteteze kuipitsidwa kwa disolo ndi utsi wa ng’anjo.

Madzi a hydrogen ndi nayitrogeni.

Flange mandala: okhala ndi silikoni mphira gasket kukhudzana ndi chivindikiro flange, mandala quartz wokhazikika kumtunda flange, chivindikiro ndi chabe detached mapiko nati flange wa mandala akhoza kutsukidwa.

Bulaketi yoyezera kutentha: Onjezani mutu woyezera kutentha kwa infrared, mutha kusintha magawo atatu kuti muwongolere.

Potulutsira madzi m’ng’anjo

10, chivundikiro cholowera

11, ng’anjo yamoto

12, chivundikiro cha ng’anjo chokweza silinda ya hydraulic hydraulic cylinder: chivundikiro cha ng’anjo yomangidwa ndikukweza manja ozungulira, chivundikiro cha ng’anjo chimatha kuzunguliridwa 20mm ndiyeno kuzungulira madigiri 0 ~ 90, chivundikiro cha ng’anjo chimakwera panthawi yozungulira.

13 , Kupinda phazi chopondapo: anakonza mu zigawo ziwiri za misalignment , amene angagwiritsidwe ntchito antchito kutulutsa zipangizo. Chifukwa cha squat yapamwamba, ma pedals amakonzedwa m’magulu awiri, mapazi atatu pamtunda uliwonse, ndipo m’munsi mwake ndi woti ogwira ntchito atenge pamwamba. Gwiritsani ntchito, gawo lapansi limagwiritsidwa ntchito ndi ogwira ntchito kuti atenge gawo lapansi. Mukamaliza kugwiritsa ntchito, pindani phazi la phazi kuti lisatenthedwe ndi sensa.

14 , ng’anjo ya ng’anjo

15. Malo otulutsirako haidrojeni, nayitrojeni, ma slag, ndi madzi.

16, kusindikiza kwa thermocouple kumatanthauza kukhala ndi mzere wa rabara wa silikoni, kusindikiza flange.

17, chubu chachitetezo cha thermocouple: chomangidwa mu thermocouple.

18 , mzati wa porcelain wotetezedwa

29 , ma porcelain pad bushings ndi ma washers adothi: kutchinjiriza magetsi.

20, coil induction.

21, mbale yothandizira zitsulo zosapanga dzimbiri.

22 , tungsten 坩埚: φ 400 × 750 × 16

23 , njerwa ya zirconia refractory

24 , njerwa za aluminium oxide refractory

25, pakati pa injini yolowera injini ndi flange, mkati mwa rabara ya fluoro, O -mphete ndi waya wamkuwa wamkuwa komanso kudzera m’madzi ozizira.

27, siteji: siteji kutalika kuchokera pansi ntchito padziko 1 8 M, kuchokera kutalika kwa ng’anjo kutsegula 0.6M, 2.9M kunja mipanda lonse kutalika, pakati anapereka Buti, Buti worktop ndi zitsulo mbale pamwamba ndi chitsanzo. Kulowa, osazembera. Bokosi lowongolera la haidrojeni ndi nayitrogeni limakonzedwa kumbali ya makwerero, ndipo mita yothamanga ya rotor ndi valve yosinthira mpweya imakonzedwa mkati kuti isinthe mpweya ndikuwongolera kuthamanga. Gantryyo imapangidwa kuti iwonongeke ndikulekanitsidwa mozungulira ng’anjo ya ng’anjo, ndipo thupi la ng’anjo limayikidwa. Mukayika, tsekani choyimira ndikumangitsani ndi mabawuti.

5, sintering ng’anjo yotentha yotentha yapakati pafupipafupi

Chotenthetsera cha tungsten crucible chimagwiritsidwa ntchito kutenthetsa chitsulo cha tungsten potenthetsera induction, kenako zinthu zomwe ziyenera kutenthedwa zimatenthedwa.

6, sing’anga pafupipafupi kupatsidwa ulemu ng’anjo refractory

Zinthu zokanira pakati pa inductor ndi tungsten crucible zimakhala ndi aluminium oxide ndi zirconium oxide. Popeza wosanjikiza wamkati ali pafupi ndi tungsten crucible ndi kutentha ndi mkulu, zirconia ndi refractoriness 2600 ° C amasankhidwa ngati zinthu refractory. Popeza wosanjikiza akunja ndi kutentha amateteza zotsatira za zirconia monga zinthu refractory ndi kutentha ndi m’munsi, ndi okusayidi zotayidwa ndi refractoriness m’munsi ndi kusungunuka kwa 2050 ° C angagwiritsidwe ntchito ngati zinthu refractory. Mwanjira imeneyi, mphamvu zonse zamoto ndi kutentha zimatha kutheka, ndipo mtengo wa zida ukhoza kuchepetsedwa moyenera.
