Advantages of Induction Heating


Induction heating is one of the most recent heating technologies mostly used in casting and automotive industries. The growing popularity of induction heating can be traced to several factors. This is the reason why most businesses prefer induction heating over radiant, convection and open flame heating. As a business, it is possible to find a used induction furnace or a metal melting furnace for your steel melting needs. However, you need to understand the advantages induction heating over other heating methods.

Optimized Consistency
When you take into account a heating method such as open flame heating, there is a lot of inconsistencies in both heating and quality. However, induction heating eliminates these inconsistencies as long as the system is calibrated and set up correctly. Generally, the heating pattern in induction heating is consistent even when power is turned on or off. So how exactly is this consistency achieved in induction heating? Induction furnaces have loop temperature control systems that ensure conformity of temperature control during heating. Advanced induction heating systems also have advanced capability to measure temperatures on individual parts. A used induction furnace can effectively optimize your heating needs just as a new one would especially if you are dealing with refurbished equipment or in precision casting business.

Maximized Productivity
One of the greatest advantages of induction heating is that it works very fast. Inside an induction furnace, heat is developed at a rate of (>2000ยบ F. in < 1 second). A used induction furnace might not automatically generate temperatures at this rate but the variance is not that great. The startup inside the induction melting furnace is instantaneous. This means that some induction heating processes that required parts to be sent in batches to a remote metal melting furnace have become faster and efficient. For example, a soldering process that would previously require offline batch heating has since been replaced by a more continuous and seamless one-piece flow production system.

Improved Product Quality
Whether you are using a used induction furnace for heating or an advanced induction system, there is improved quality of the end product. This quality upgrade is mainly because in induction heating, the part being heated is never in direct contact with the heating element of flame. The heat in in fact induced into the part through alternation of electric current. In order to prevent oxidation during the heating process, the part can be placed in an enclosed space or a vacuum.


A Reduction in Energy Consumption
Utility costs are sometimes a huge nightmare for businesses that use heating during production. For example, a typical melting furnace is only 45% energy-efficient but if you decide to use an induction furnace, the energy efficiency is significantly improved. Ideally, induction heating requires no cool down or warm up cycle-which is why energy is greatly conserved during the heating process. In addition to this, induction heating is often compatible with most energy-efficient system because of the consistency in heating further reducing energy consumption.

Environmentally Sound
Induction heating is one of the most non-pollutant heating methods when compared to other heating methods such as open flame or convection heating. This is because in induction heating, no burning of traditional fossil fuels occurs. You can easily improve the working conditions of your staff by eliminating common workplace excesses such as noise, heat waste and noxious emissions. More importantly, there is no open flame during the heating process that can expose your employees to greater risk. Without the risk of an open flame, it means that your business can use non-conductive materials in close proximity to the induction furnace.
