What are Pusher Furnaces and How Do They Work?

The metallurgical study is an essential part of our day to day lives owing to the increasing demand for well-crafted metal utilities. To meet the market demands, technology has risen to help in the development of craftsmanship in engineering. In this process of upgrading the methods to curate efficient mechanisms, a number of products and technologies have been developed over the years. Of them, pusher furnaces are of immense importance.

What do you mean by Pusher Furnaces?

A pusher furnace is an instrument that is used for continuous processing. Industrially, metal pieces that are heated and processed into desired utilities need to be exposed to heat at a continuous pace. Doing this using human labour is not feasible owing to the high risks involved that may lead to fatality. However, by designing a special type of furnace in which the mechanism of continuous pushing is used, the desired result can be sought for.

How do Pusher Furnaces work?

Pusher furnaces are continuous furnaces in which metal goods or elements can be passed for processing. The goods that are needed to be processed have to be loaded onto a tray or a basket depending upon the size and weight. Therefore, the tray or the basket to be used must be durable. Following the loading, the tray or the basket has to be pushed into the furnace across the hearth for heating. The pushing of the tray is done using electric or hydraulic forces. The electric or hydraulic pushers are so designed that they are able to function without hindrance from behind the charge of a Pusher Furnace for Continuous Type Heat Treatment.

What are Pusher Furnaces used for?

Pusher furnaces are an essential aspect of the metallurgy industry in which heavy and light metal goods need to be processed. Using pusher furnaces, a metal good can be subjected to two main categories of desired output. First, the goods can be pushed into the furnace for being shaped with the infliction of hot pressure. Secondly, a metal good can be processed in a Pusher Furnace for Continuous Type Heat Treatment. These two broad classifications decide the fate of the metal good that is processed to be crafted into an efficient design that can be used further.

Why is the Pushing Technique used?

There are various techniques using which a metal good can be processed by exposing the same to heating. Of all the available techniques, the pushing technique has a widespread use. This can be justified because of the simplicity of the technique. It is much easier to get to tune electric and hydraulic systems to work as pushers than anything else and, hence, this technique is quite popular when it comes to affordability and convenience.

Does the Pushing Technique cause obstructions?

The pushing technique for heating and processing metal goods is very efficient. At the same time, this technique is not flawless. It is quite difficult to design the pusher in a way that it functions smoothly for every metal size that is loaded for heating into the furnace. It is often seen that the metal undergoes scraping against the hearth due to incorrect placement. Pushing at this stage makes the frictional force generated scrape off the metal pieces from the surface in contact with the hearth. To avoid this, the trays or baskets have to be built such that enough space is available between the metal good and the surface of the hearth.

Should Pushing Furnaces be used?

Pushing furnaces are, by far, the most flexible furnaces available. Despite the minor flaws, the efficiency at which the task is carried out under optimum condition is commendable. To remove the existing flaws, greater technology is being implemented to design high-grade pusher furnaces of rotary, roller-hearth, walking-hearth and rotary-ring types to suit the needs.

Hence, it can be concluded that pusher furnaces are one of the most efficient technologies which are safe to be used for the processing of metals. At present, this technique is being developed further to obtain better and intricate results. Hence, the possibilities are endless and should not be overlooked.
