China's refractory industry should accelerate the promotion and application of industrial microwave equipment

Industry expert Zhang Rui, vice president of Zhengzhou Institute of Aeronautical Industry Management, said: At present, the refractory materials and ceramics industries in developed countries are increasingly using industrial microwave ovens as heating and drying devices. China's industrial microwave ovens have only begun to develop in recent years. The total power of microwave ovens is less than 10,000 kilowatts. The major enterprises of industrial microwave oven enterprises in China are located in Zhengzhou, Henan, Guangzhou, Zhuzhou and other places in Henan Province. There are certain representative enterprises such as Henan Boda, Nanjing Sanle, Guangzhou Kewei, Zhuzhou Zhiyuan, etc. These enterprises are all industrial microwave ovens in China. The promotion and application made a lot of contributions. However, the overall level of our country lags behind that of some other industrialized countries and urgently needs to accelerate the pace of development and popularization.

China's electricity supply is insufficient, and microwave ovens have obvious power-saving benefits. Therefore, it is necessary for China's refractory and ceramic industries to substitute new-type industrial microwave ovens for those electric heating devices that consume large amounts of energy and time, making China's refractory and ceramic industries Drying technology and equipment have been upgraded to a new level.

Industrial microwave ovens use microwaves as heating energy, consisting of electromagnetic waves at a frequency of several billion Hz per second. When the refractories are dried, the refractories are exposed to the microwave electric field. Under the action of the electric field, the moisture in the material generates billions of vibrations, collisions, and frictions per second until it circulates, generating kinetic energy, and is very short. The internal heat of the material is caused within the time, and then the material is gradually heated from the inside to the outside, just opposite to the traditional heating method. The biggest feature of industrial microwave ovens is that they work at room temperature, and they also have the following advantages:

Fast and efficient Because the industrial shock wave furnace can heat instantly, it can greatly save the drying time of the refractory material. Compared to traditional drying methods, microwave heating saves two-thirds of the time. Increases production efficiency by 100% to 300% compared to conventional heating devices.

Energy-Saving and Power Saving Although the power of industrial microwave ovens is relatively large, due to the short drying time of the refractory materials, it generally saves 50% to 70% of the energy of the infrared heating devices, and the dehydration capacity per degree of electricity is 5 times that of infrared rays.

Save equipment space General industrial microwave ovens can complete the workload of more than two common heating equipment, thus saving equipment space and saving many equipment purchase costs. In addition, industrial microwave ovens also have features such as easy maintenance and low cost.

It is particularly affirmed that Henan Boda Microwave Equipment Co., Ltd. has adopted new technologies and completed the R&D and production of ultra-large industrial microwave drying special production line equipment, and successfully applied it to the refractory production industry, achieving great economic effects. Recognized and praised by the domestic refractories industry, it has solved the problem of atmospheric pollution that has plagued the refractories industry for many years and reduced the practical problems of energy. It has been recognized by many customers.
