Heating Characteristics of Medium Frequency Induction Furnaces
2022.10.17
Medium frequency induction furnaces are a leading choice in the global metal processing industry, valued for their efficiency, rapid heating, and clean operation. From forging and casting to precision heat treatment, these furnaces provide consistent and cost-effective heating solutions.
In this article, Luoyang Judian outlines the key heating characteristics of medium frequency induction furnaces and how they benefit modern manufacturing processes.
Efficient Electromagnetic Heating
The core operating principle of a medium frequency furnace is electromagnetic induction. Heat is generated directly within the metal workpiece through eddy currents induced by a medium frequency magnetic field. This method requires no direct flame or contact, enabling fast and efficient heating.
Compared to traditional furnaces, induction systems allow operators to start production within minutes. There is no need for preheating or continuous operation overnight, reducing energy consumption and labor requirements.
Low Oxidation and Material Waste
Induction heating minimizes oxidation and material loss during processing. Oxidation rates by furnace type:
Induction furnace: approximately 0.5%
Gas furnace: approximately 2%
Coal furnace: up to 3%
This efficiency translates into reduced waste. An induction furnace can save 20 to 50 kilograms of steel per ton of forgings, with a steel utilization rate of up to 95 percent.
Uniform Temperature and Improved Quality
The temperature within the workpiece is evenly distributed, with a minimal difference between the surface and the core. This consistency improves product quality and extends tool and mold life. Additional benefits include:
Reduced forging die wear
Surface roughness typically below 50 microns
Lower rejection rates due to temperature inconsistencies
Enhanced mechanical properties of finished parts
Energy Savings and Operational Cost Reduction
Medium frequency induction furnaces offer 5 to 40 percent energy savings compared to coal or gas-fired furnaces. Combined with faster cycle times and reduced scrap, these savings lead to a significant reduction in overall production costs.
Cleaner, Safer Working Environment
Induction furnaces eliminate open flames, smoke, and direct combustion. This not only meets environmental regulations but also significantly improves workplace conditions:
Reduced heat radiation
No harmful gas emissions
Lower physical strain on operators
Improved safety and comfort result in higher productivity and reduced labor turnover.
Versatile Applications Across Metals
Luoyang Judian’s induction furnaces are designed for versatility and adaptability. They can be used for:
Melting ferrous and non-ferrous metals such as pig iron, stainless steel, tool steel, copper, aluminum, gold, silver, and their alloys
