State and support is provided with the inside of fire door, described infrared thermometer is arranged on support.
When the utility model is used, infrared thermometer monitors the temperature in spun furnace main body, and temperature is passed to closes
In ring control system, information is processed and is communicated to according to work at present progress after PLC receives temperature information
PID adjustment modules, then heater, cooling device and vacuum extractor are adjusted by PID adjustment modules, then heating is filled
Put, cooling device and vacuum extractor are made and perform action, then the temperature in spun furnace changes, then by infrared thermometry
Instrument detects newest temperature and is delivered to next link, so as to realize spun furnace from the full-automatic control for being preheated to casting process
System.Meanwhile, PLC and PID adjustment modules can be by real-time Data Transmissions to display screen, so that supervisor can be from aobvious
The information such as the temperature in spun furnace, the order being carrying out are obtained in display screen.
The beneficial effects of the utility model are：1., by the effect of spun furnace melting automatic control system, band is got rid of in realization
Stove is from the Automatic Control for being preheated to casting process, it is possible to reduce operating personnel, reduces human cost；2. the life of product is made
Product process uniformity is improved, and contributes to the uniformity of product to improve, it is ensured that the quality of product.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is the sectional view of spun furnace main body.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
1~Fig. 3 of reference picture, a kind of spun furnace melting automatic control system, including spun furnace main body 1, described spun furnace
