Take you to understand the fully automatic temperature closed loop intermediate frequency magetsi oyatsira moto

The 750KW/1.0KHZ intermediate frequency induction heating furnace adopts three automatic selection mechanisms of feeding, feeding, discharging and temperature. The specially proposed temperature closed-loop control uses two power supplies and three sensors. The thermometer adopts perforated temperature measurement, the first thermometer is in the preheating section, and the second thermometer is at a certain position away from the furnace outlet. The first thermometer collects the temperature of the specific temperature measurement point and feeds it back to the PLC. The PLC intelligent output ensures that the temperature of the furnace outlet meets the set temperature. Two thermometers, two power supplies, multiple sensors, modular design It constitutes a fully closed-loop temperature control system.

Njira zazikuluzikulu za ng’anjo yotenthetsera yapakati pafupipafupi ndi izi:

1. Zinthu zopanda kanthu: 45 # zitsulo, etc.

2. Mitundu yazinthu zopanda kanthu: m’mimba mwake Φ70-160, kutalika 120-540. Mipiringidzo yambiri imadyetsedwa ndi mtundu wa washboard, ndi omwe amaposa makina odyetserako zakudya kapena amadyetsedwa pawokha poyambira ngati V.

3. Kutentha kutentha: 1250 ℃.

4. Kumenya: Zopanda kanthu Φ120, kutalika 250mm: 44 masekondi / chidutswa. Diameter Φ90 ndi kutalika 400mm: 40 masekondi / zidutswa. Diameter Φ150 ndi kutalika 300mm: 82 masekondi / chidutswa.

5. Kutentha kumakhala kokhazikika panthawi yogwira ntchito, ndipo kusinthasintha kwa kutentha pakati pa gawo lililonse la zinthu kumakhala mkati mwa ± 15 ° C; axial ndi radial (tebulo pachimake) ≤100°C.

6. Kuthamanga kwa madzi ozizira kumapangitsa kuti madzi azizizira kwambiri kuposa 0.5MPa (kuthamanga kwa madzi wamba kumakhala kwakukulu kuposa 0.4 MPa), ndipo kutentha kwakukulu ndi 60 ° C. Kuthamanga kofananira kwa payipi ndi mawonekedwe ake ziyeneranso kuchulukitsidwa molingana ndi miyezo yachitetezo.
