Research On Frequency Conversion Water Cooling Control System Of Intermediate Frequency Furnace

With the development of science and technology and national economy,all walks of life are put forward higher requirements on the casting production,and smelting furnace is an important equipment of foundry industry,automatic control technology is adopted to effectively improve the efficiency and performance of medium frequency furnace is very important.This paper in order to improve the casting production capacity and work efficiency,saving energy and reducing consumption as the goal,according to the Shijiazhuang Industrial Pump Company Limited three mine branch foundry are melting capacity,cooling water system obsolete,waste water energy and other issues,on the basis of the original equipment can be matched,added 3 tons and 10 tons of intermediate frequency melting furnace holding furnace,and the design of speed control of water cooling system can be based on PLC and inverter frequency furnace.This paper introduces the structure of the basic knowledge of induction heating and intermediate frequency furnace,analyzes 3 tons of intermediate frequency furnace body comprises a furnace,crucible,sensors and other process parameters,determine the selection of medium frequency power supply parallel resonant frequency power supply,data related to the rectifier and inverter part and calculate the.According to the control requirement of the intermediate frequency smelting furnace cooling water,the requirement of energy saving and environmental protection is fully considered,the PLC control inverter is designed,and the instant communication between the touch screen and the two operating modes in summer and winter are designed.The cooling water needs to be supplied,the energy saving and the intermediate frequency furnace are safe and reliable,and the production capacity and the efficiency are ensured...
