An Introduction to Functioning of Resistance Heated Furnaces
As the furnace manufacturing technology has advanced considerably, many new concepts have emerged in this area. Gone are the days of simple wood or coal fired furnaces and experts have come up with various new approaches and technologies based on which furnaces work. One key advancement has been the emergence of resistance heated furnaces. These are a type of industrial furnace that uses electrical resistance to generate heat. These furnaces are designed to heat materials to high temperatures and are commonly used for a wide range of applications, including heat treating, annealing, and brazing. The basic principle of resistance heating is that an electrical current is passed through a resistive material, such as a coil of wire, which generates heat. In a resistance heated furnace, the resistive material is typically a coil of wire that is wrapped around the heating chamber. When an electrical current is passed through the coil, it generates heat, which is then transferred to the materials inside the heating chamber.
Key advantages of resistance heater furnaces
One of the main advantages of resistance heated furnaces is that they are relatively simple to operate and maintain. Unlike other types of industrial furnaces, such as gas or oil-fired furnaces, resistance heated furnaces do not require a fuel source and do not produce any emissions. This makes them a clean and environmentally friendly option for many industrial and laboratory settings.
Another advantage of resistance heated furnaces is that they are highly precise and can generate very high temperatures. Because the heat is generated by electrical resistance, the temperature can be easily controlled and regulated, which makes them ideal for applications that require precise temperature control, such as heat treating and annealing.
Common Applications of These Industrial and Laboratory Furnaces
Resistance furnaces are also versatile and can be used for a wide range of applications. They are commonly used for heat treating, which involves heating materials to high temperatures to change their properties, such as strength and hardness. They are also used for annealing, which involves heating materials to a lower temperature to make them more flexible and less brittle. Additionally, they are also used for brazing, which involves heating materials to a high temperature to join them together. The furnaces are also widely used in the manufacturing industry, especially in the aerospace, automotive, and defense industries. They are also used in the production of semiconductors and electronic devices, as well as in the ceramic and glass industries.
In addition, some resistance furnaces are also used as laboratory furnaces as they are specially designed to be used in laboratories and research settings. These furnaces are typically smaller and more compact than industrial-grade furnaces and are designed to be used for a wide range of applications, including metallurgy, materials science, and ceramic research. Since all these areas require very high degree of precision in terms of the temperature they can reach and operate at, and at the same time they need to maintain a very clean operating environment so that anything left from one experiment does not impact other experiments, laboratory furnaces which use resistance heating tend to become the preferred choice by many a scientists.
The times of old unclean and clunky furnaces which were either powered by timber or by fossil fuels have passed in most of the developed markets and these high tech furnaces are also very close to becoming highly affordable and easily accessible even for people and businesses who do not have a lot of scope in their budget. As more and more time passes and economies of scale continue to build up, the resistance furnaces are expected to become the go-to option for everyone.
