What are the factors affecting the power consumption of medium frequency furnace?

The medium frequency furnace is a heating equipment specially used for heating metal blanks. It has the advantages of fast heating speed, high productivity, strong adaptability, flexible use, convenient start-up operation, and high degree of automation. Since it is a high-power electric heating equipment, its power consumption is particularly important in production. Understanding the factors affecting the power consumption of the medium frequency furnace is the first thing we should consider when designing, manufacturing, selecting and using it.

In order to reduce the power consumption of the medium frequency furnace, it is necessary to understand the factors affecting the power consumption of the medium frequency furnace. The four main factors affecting the power consumption of the medium frequency furnace are:

1. Medium frequency power supply: The configuration level of the power density of the medium frequency furnace meets the heating requirements for the best, but the large selection of high-power medium frequency furnace wastes heating power and affects the power consumption of the medium frequency furnace. The wiring inside the power cabinet of the medium frequency furnace is messy, which will affect the processing capacity of the power supply, resulting in unstable power supply, low power conversion efficiency, and low energy consumption.

2. Medium frequency heating: During the medium frequency heating process, the cleanliness of the surface of the metal raw material is also a factor affecting energy consumption. It is calculated that if there are 5% impurities in the heated metal raw materials, 5% of electrical energy is required to melt these impurities, which will affect the service life of the lining. The appropriate length of the furnace body will affect the electrical efficiency and melting quality of the medium frequency furnace, generally 200~300mm is appropriate;

3. Refractory materials: The use of suitable lining refractory materials for the medium frequency furnace can increase the heating speed. Quartz sand refractory materials have high temperature resistance and can be used with medium frequency furnaces. The metal materials in the lining generate heat through induction heating, which can reduce heat transfer consumption.

4. Improper operation of the medium frequency furnace will lead to high energy consumption: the temperature of the medium frequency furnace heating metal is too high, exceeding the requirements of the thermal process, causing the heated metal to overheat. This operation is not only unsafe, but also increases energy consumption and destroys the metal structure, which is harmful but not beneficial.

In short, there are many factors that affect the energy consumption of the medium frequency furnace, among which the above four factors are particularly important. It is hoped that they can be improved in the production of the medium frequency furnace to avoid unnecessary medium frequency furnace electricity consumption and reduce production costs, thereby improving the heating production efficiency of the medium frequency furnace.
