Take you to understand the fully automatic temperature closed loop intermediate frequency induction inapokanzwa tanuru

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.

Vigezo kuu vya mchakato wa tanuru ya joto ya induction ya mzunguko wa kati ni kama ifuatavyo.

1. Nyenzo tupu: 45 # chuma, nk.

2. Upeo wa vipimo tupu: kipenyo Φ70-160, urefu wa 120-540. Baa nyingi hulishwa kiatomati na aina ya ubao wa kuosha, na zile ambazo huzidi safu ya mashine ya kulisha au hulishwa kwenye groove ya umbo la V kwa mikono.

3. Joto la kupasha joto: 1250℃.

4. Piga: Kawaida tupu Φ120, urefu 250mm: sekunde 44 / kipande. Kipenyo Φ90 na urefu 400mm: sekunde 40 / vipande. Kipenyo Φ150 na urefu 300mm: sekunde 82 / kipande.

5. Inapokanzwa ni imara wakati wa operesheni ya kawaida, na mabadiliko ya joto kati ya kila sehemu ya nyenzo ni ndani ya ± 15 ° C; axial na radial (meza kuu) ≤100°C.

6. Shinikizo la mfumo wa usambazaji wa maji baridi ni kubwa kuliko 0.5MPa (shinikizo la kawaida la maji ni kubwa kuliko 0.4 MPa), na joto la juu ni 60 ° C. Shinikizo la hose sambamba na kiolesura pia kinahitaji kuongezwa sawia kwa viwango vya usalama.
