Hydrogen wapakatikati frequency induction sintering furnace

A, kuwunikira kwa hydrogen wapakatikati frequency induction sintering furnace

1

2. Application of hydrogen intermediate frequency induction sintering furnace : used for sintering tungsten plate (rod) billet

3, hydrogen sing’anga pafupipafupi yotchinga sintering ng’anjo zofunika kwambiri: hydrogen sing’anga yotsekemera yotentha ndi ng’anjo ndiyofunikira kuti zitsimikizike, zodalirika, komanso zomveka bwino, zogwira ntchito, zosavuta kugwira ntchito ndi kukonza

B. Kusankhidwa kwa magawo aukadaulo wa hydrogen wapakatikati pafupipafupi wopangira sintering

1 , a sintered material: tungsten

2, kutentha kogwira ntchito: 2 30 0 deg.] C (kutentha 8H)

3, kutentha molondola: ± deg.] C. 1

4, kufanana kwa kutentha: mu -380 × 700 mkati mwa ± 15 deg.] C (njira zovomerezera: kutentha kwapakati pamalopo, pakati pa nyemba iliyonse kuyikidwa kocheperako kwa mtundu uliwonse wazitsanzo. kupatuka sikuli koposa 0.2g / cm3)

5, Tungsten Crucible Kukula: Ф450 (mkati mwake) ×. 8 50 (okwera) × 16 (makulidwe) mm

6 , a single furnace sintering quantity:    200Kg

7 , pre-vacuum degree:    10 Pa

8. Pre-vacuum time: less than 30 minutes when the furnace is empty

9, kuwongolera kutentha: Kutentha kokha, magwiridwe antchito akhoza kukhala

10, kuchokera munjira yodyetsera: kugwiritsa ntchito chindapusa

11 , working system: three shifts of continuous

12, Kutentha mphamvu: kutentha kwambiri gawo 2 0 0 deg.] C / H.

13. Kutentha kwamatangi: osakwana 50 ℃

C, hydrogen sing’anga pafupipafupi yochotsa uvuni zofunikira kwambiri

1, koyilo yochotsa

Gwiritsani chubu lopanda oxygen lopanda mpweya pambuyo poti annealing, utsi wa epoxy utomoni wothandizira kutchinjiriza, ndikupatsanso lipoti loyesa hydrostatic

2. Mbiya

Using Ф450× 8 50×16mm tungsten crucible ,

3. Zida zotchinjiriza

Zirconia zoyera kwambiri ndi njerwa za alumina zoyera kwambiri, njerwa zotchingira pogwiritsa ntchito 40mm zirconia, 30mm alumina, ndi 70mm zirconia pansi zimatha kutsimikizira kugwiritsidwa ntchito kotentha kwambiri ndikugwiritsanso ntchito satifiketi yofananira.

4.

5, kuwongolera kutentha

(1) Thermometer: Gwiritsani ntchito tungsten rhenium thermocouple pansipa 1200 ℃ Gwiritsani ntchito mitundu iwiri ya colorimetric mrisc1000 ~ 3000 pyrometer yamagetsi pamwambapa 1200 ℃, kutembenuka kozungulira kukhala kutentha

(2) Woyang’anira kutentha: FP23 woyang’anira kutentha

(3) Kutentha ndi zingalowe: chojambula chopanda mapepala

6, mayunitsi opanda kanthu

(1) Mpope wamakina: 2x-70 mtundu wozungulira wopopera pampu

( 2 ) Solenoid valve : ddc-tq80 solenoid with inflation valve

( 3 ) Metal vacuum gauge, low vacuum gauge :

7, dongosolo lamagetsi lamagetsi:

(1) Mphamvu yamagetsi imakhala ndi chitetezo chamakono komanso chopitilira muyeso, ndipo gulu loyang’anira limagwiritsa ntchito gulu lazachisanu lazoyang’anira.

( 2 ) SCR and comes with half a set of spare parts

8, ng’anjo:

(1) Khoma lamkati la ng’anjo limapangidwa ndi 304 zosapanga dzimbiri, makulidwe ake ndi 8mm; khoma lakunja limapangidwa ndi 35 # chitsulo, makulidwe ake ndi 10mm, ndipo limakhazikika m’madzi. (2) Dzenje lowonera ndi losavuta kuyeretsa

( 3 ) Manual hydraulic lifting and manual rotation of furnace cover ( self-locking during work )

(4) Thupi lamoto limakhala ndi njira zophulika (mtundu wamasiku)

9. Njira yozizira:

The main cooling portion (SCR, inductor, capacitor ) , and return each branch temperature , pressure monitoring test , once the failure is automatically power off

10. Natural backwater is adopted as the backwater method

D, kapangidwe ka haidrojeni wapakati pafupipafupi induction sintering furnace
