Electromagnetic induction heater is a principle to the use of electromagnetic energy to thermal energy conversion devices. Electromagnetic internal heater in from the AC voltage rectifier circuit will hum into DC voltage, After control circuit (electromagnetic heating controller) 20-40KHz DC voltage conversion frequency of the RF voltage, rapid changes in current flow through the coil will produce rapid changes in the magnetic field. When the magnetic field lines through a magnetic field (or conductive material) base metal bodies produced countless small eddy. high heat conductive material so on its own, and then the heat conductive material things.

Electromagnetic induction heating technology in the plastics machinery of release dates : 2006-9-26 information sources : Changsha Yihong Technology Ltd. 1. At present, the government has been advocating universal electricity, joint action. China's power shortage and the provinces, according to the Electric Power Supervision Committee published "The situation of power supply and demand analysis and recommendations," disclosed, has reached 18. More than 140,000 of the total power cuts throughout the meeting, a total of 19 billion kilowatt-hours of electricity restrictions. Power shortage has seriously constrained China's economic development. Therefore, the government vigorously support energy-saving, environmental protection industries. According to incomplete statistics, there are now approximately 160 million sets of plastic machinery production, the rate of 15% annually. -- part of the heating capacity of 20 million kilowatts. Daily consumption is about 20 million kilowatts hours = 2 × 20 × 0.5 billion kilowatt hours. (0.5 for the heat off than machines, machines for 20 hours a day production). machine for every 300 working days per year, the annual consumption of plastic processing machinery 600 billion kilowatt hours. If all the machines are installed electromagnetic heating device, then save the country about 180 billion kilowatt hours of electricity. This year the Gezhouba generating capacity has more than 23 million kilowatt-hours of electricity to ease tension in the country. lower investment and lower production costs in the state have a very positive impact and significance. 2. Currently the plastic industry is very keen competition, and how to reduce product cost and improve the competitiveness of their products. Every enterprise is the core issue in the plastics industry and electric products account for a large fraction of the cost. the use of electromagnetic heating technology enterprises can effectively reduce production costs and enhance competitiveness. Domestic situation and the problems that exist A plastics industry. Products Industry : plastic products, plastic film, plastic granulator, drawing injection molding, pipe and other production enterprises. Currently, the production facilities of these enterprises are using electric heating ring to melt and die. after the melt-down of plastic raw materials to make plastics injection mold, draw, extrusion molding products. B. Problems : (1) : a big heat loss, the use of the existing heating, by winding wire resistance, Double heat outside the ring, inside (close Barrel) to melt the heat conduction. Most of the dissipation of heat and outside air, causing the loss of electric waste. (2) : As the temperature increased calorie lost, the surrounding temperature. Summer is a particularly significant impact on the environment, the site of the temperature exceeded 45 ° C, Some enterprises have air-conditioned lower temperature, which causes a waste of energy in the second. (3) Life is short, maintenance : As a large amount of resistance wire heating, the heating temperature to 800 ℃. easy to burn the high-temperature aging resistance wire, used electric circle about life in about half a year, so maintenance of a relatively large workload. 2. A heater in the electromagnetic characteristics and advantages. Compared to the original effective energy-saving result in resistance wire circles for more than 30% relative to the different materials, production of different products, energy-saving effect change. But the products have been used in the current power saving of up to 75% maximum efficiency. B. Good results can significantly reduce environmental temperature. C. Long life operation of the heating temperature of 100 ° C continuous circle around, there is no replacement of the heating ring. Compared with the original resistance wire reduces the chance of secondary input. D. Because the product can increase the production of high-efficiency heating, can significantly reduce heating time and improve product yield. Application examples : My company manufactures plastic film plant in Nanjing transform a 11 kW heating power for the Color Mixing Machine. Before the transformation, the aircraft 110 degrees for the 24-hour power consumption. After the transformation, the power consumption of 62 aircraft, power saving rate of 43%. Electricity plant 0.9 yuan /, or a monthly savings in electricity charges : 48 degrees × 0.9 yuan / =1296 degrees x 30 days, Taiwan plant currently has 30 such machines, if all of the transformation is completed, will save electricity for 39,000 2.The. This year will be 480,000 yuan for savings and investments were less than 200,000 yuan.

Electromagnetic Induction Heating Technology in the field of energy release dates : 2006-9-26 information sources : Changsha Yihong Technology Ltd. Changsha Yihong Technology Ltd. is a high-tech private-owned enterprises, Energy committed to product design, development, production and marketing. The company was founded in 2005, is located in the beautiful star-Changsha. Electromagnetic heating energy as a domestic industrial technology programs, and providers, promote energy-saving projects focus on the state model, since the date of the establishment, it based on the electromagnetic heating and energy-saving products (electromagnetic heating ring, electromagnetic heating controller) research and development, production, The program provides marketing and technology. Heating energy electromagnetic fields in the pipeline, the world's leading position. Supporting manufacturers, the company has passed ISO9001 : 2000 quality system certification. advanced production equipment and testing equipment to ensure that customers with high-quality products. Currently, the theme of domestic companies have applied for patents from the state as a substitute for traditional electric products. widely used in plastics, rubber products, chemicals, medicine, food, energy, printing, building materials and heating industries such as electricity, such as : Plastic Drawing, Color Mixing, granulation, such as injection heating; Cable extruder, extruder, thermoplastic plastic pipe. Profiles production of heating; Heat pipes, heating and temperature control. With the rapid growth of the world economy, a shortage in the supply of energy and raw materials. China is a big country plastics, energy consumption is very alarming rate in recent years, with the increase in manufacturing costs.
