A Guide To Industrial Furnaces and Their Types

There are many industries that use different industrial furnaces for different uses such as chemical, biochemistry, metalworking, medical devices, jewelleries and many more. Many furnaces work with various materials, including powdered metals, solid metals, ceramics, glass melting furnaces, and many more.

Depending on the application, these furnaces are made in different shapes and sizes to produce a range of atmospheres and temperatures. The primary examples are that the factory and lab use for manufacturing and research, checking the combustibility of the chemicals, hardening the metals for use in bearing balls, or uniform drying of the paper pulp. This post closely discusses parts and features that industrial furnace company use for making industrial furnaces.

Parts And Features Of Industrial Furnace

From the outside, industrial furnaces look simple, but there are many complexities involved within the furnace. Variations in the furnace features and parts allow for many options for thermal processing and heat treatment applications. Following are the most common components founded in the commercial furnaces, such as

  • Muffles

Muffles are used for creating separate chambers for fuel combustion and for heating. It is essentially important to avoid contamination from the byproduct’s combustion. They are also the cooling and preheating zones or areas for holding materials at high temperatures. Muffles are either made up of ceramic or metal.

  • Double and Simple Chamber Design

The cooling and heating occur in the same chamber in the simple chamber furnace. On the other hand, the double chamber furnace has two areas specifically made for cooling and heating. A door separates to keep the atmosphere and temperatures from mixing. 

The design of the double chamber glass melting furnaces retains the heat generated within the chamber instead of leaking it every cycle as the chamber cools down. The double chamber furnace is more efficient and affordable since only the material is heated every cycle, not the whole chamber. It is also possible to offer two atmospheres in specific chamber.

  • Heat Source

The best industrial furnace company makes these furnaces in a way so that they can also be heated with natural gas combustion, electric heating coils, and electric boilers. Which is why you should consider your needs such as needed temperature, material you want to melt to choose the best furnace system.

  • Control Systems

Some furnaces also comes with digital control and monitoring systems. It is also possible to track the performance trends such as belt speed, temperature fluctuations, or fan speed over time. Some features send alerts and reports to the operators and reminders for the system testing. 

Processes Industrial Furnaces Helps To Complete

The majority of components listed above are available in any type of furnace. There are also many processes for which industrial furnaces are used, such as:

  • Annealing

The annealing process is used for heating the metals to very high temperatures to enhance the machineability and reduce the brittleness. In this, timing is necessary so that the temperatures of the material in the furnace can be raised or lowered to find the perfect temperature.

  • Brazing

The brazing process is used for joining the metal components with the dissimilar filler metal at a temperature of 1288 ̊C / 2350 ̊F. It is usually used with the base metals such as carbon steel, copper, stainless steel, and brass, as well as filler metal such as copper, nickel alloys, and silver. 

  • Heat Treatment

These furnaces are customized for many heat treatment processes followed by rapid annealing and quenching. They are generally used for tempering the austenitized and quenching the hardened steel or the iron temperatures below the temperature of 1300°F and hardened steel around 300°F.

Before choosing the industrial furnace, you will have to consider your requirement and applications to get the best and most efficient furnace for your needs.
