Pusher Furnace Reheating
Pusher Furnace Reheating is a type of heat treatment which is used to provide a consistent and uniform microstructure throughout a material. It is an integral part of heat treatment cycle. In this process, the material is heated up above its recrystallization temperature and captured between two rolls. The material is then pushed through a reheating furnace with a rolling action in order to ensure a uniform temperature that is distributed throughout, giving it the desired properties.
The basic principle behind the Pusher Reheating process is that a uniform heating of the material with a set temperature is necessary in order to bring it to the desired microstructure. During the heating phase, the material is pushed through the furnace in a continuous motion, allowing it to achieve a uniform temperature distribution. This method is beneficial as it helps eliminate defects such as warping, shrinkage or oxidation and can help to improve the mechanical and physical properties of the material as well. Additionally, the uniform heating of the material also allows for a better control on the cooling process, which is an important factor in the overall heat treatment cycle.
There are several different types of pusher furnaces that can be used for reheating a material. Depending on the type and size of the material and the desired properties, the right type of furnace can be selected to best suit the needs. These furnaces can be operated in a range of temperature up to 1000°C and typically consist of heat elements located around the periphery and a pusher bar that can push the material along.
As with all heat treatments, there are certain aspects to consider when selecting the right equipment for the application. It is important to select the correct type of furnace, such as an induction or gas-fired pusher furnace, as these are the most efficient. Other factors to consider include the type of material, the quantity of the material, the heat elements and the type of cooling method used.
Using the Pusher Furnace Reheating process is an effective way to provide a consistent microstructure throughout a material and offers a wide range of advantages over other heat treatments. It is a cost-effective and efficient method for providing a uniform heating of the material and is well suited for many different types of materials. With the right equipment and a careful selection process, it can be used to achieve the desired properties for many different applications.
