Take you to understand the fully automatic temperature closed loop intermediate frequency ukufudumeza iziko

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.

Iiparamitha eziphambili zenkqubo ye-intermediate frequency induction furnace zimi ngolu hlobo lulandelayo:

1. Izinto ezingenanto: 45 # intsimbi, njl.

2. Uluhlu lweenkcukacha ezingenanto: ububanzi Φ70-160, ubude be-120-540. Uninzi lweebhari zondliwa ngokuzenzekelayo ngohlobo lwebhodi yokuhlamba, kwaye ezo zidlula uluhlu lomatshini wokutyisa okanye zondliwa kwi-V-shaped groove ngesandla.

3. Ubushushu bokufudumala: 1250℃.

4. Ukubetha: Isiqhelo esingenanto Φ120, ubude be-250mm: imizuzwana ye-44 / isiqwenga. Ububanzi be-Φ90 kunye nobude be-400mm: imizuzwana ye-40 / amaqhekeza. Ububanzi Φ150 kunye nobude 300mm: 82 imizuzwana / iqhekeza.

5. Ukufudumala kuzinzile ngexesha lokusebenza okuqhelekileyo, kunye nokufudumala kweqondo lokushisa phakathi kwecandelo ngalinye lezinto eziphathekayo ngaphakathi kwe-± 15 ° C; i-axial kunye ne-radial (itafile engundoqo) ≤100 °C.

6. Uxinzelelo lwenkqubo yokubonelela ngamanzi okupholisa lukhulu kune-0.5MPa (uxinzelelo lwamanzi oluqhelekileyo lungaphezu kwe-0.4 MPa), kwaye ubushushu obuphezulu bungama-60 ° C. Uxinzelelo lombhobho ohambelanayo kunye nojongano nazo kufuneka zonyuswe ngokulinganayo kwimigangatho yokhuseleko.
