What is a mesh belt furnace?
A Mesh Belt Furnace, also known as a Mesh Belt Conveyor Furnace, is a type of continuous industrial furnace commonly used for various heat treatment processes, such as sintering, brazing, annealing, and drying. It is designed to convey workpieces or materials through the furnace on a continuous mesh belt or conveyor system.
The primary feature of a Mesh Belt Furnace is the mesh belt itself, which is typically made of a heat-resistant alloy or stainless steel. The mesh belt acts as the conveyor that transports the workpieces or materials through the furnace, facilitating their exposure to controlled temperature zones.
The operation of a Mesh Belt Furnace typically involves the following steps:
-
Loading: The workpieces or materials to be heat treated are loaded onto the mesh belt or conveyor system outside the furnace.
-
Heating: The furnace is heated to the desired temperature using burners, electric heating elements, or other heat sources. The heat is transferred to the furnace chamber, raising the temperature to the required level for the specific heat treatment process.
-
Conveyor Movement: The mesh belt or conveyor system moves the workpieces or materials through the furnace chamber at a controlled speed. The movement can be continuous or step-wise, depending on the specific process requirements.
-
Heat Treatment: As the workpieces or materials pass through the furnace, they are exposed to different temperature zones and dwell times for the required heat treatment process. This can include heating, soaking, cooling, or any other required stages.
-
Unloading: Once the heat treatment process is completed, the workpieces or materials are unloaded from the mesh belt or conveyor system at the end of the furnace for further processing or handling.
Mesh Belt Furnaces offer advantages such as uniform heating, precise temperature control, and the ability to handle a continuous flow of workpieces or materials. They are commonly used in industries such as automotive, electronics, ceramics, and metal manufacturing, where continuous and efficient heat treatment is essential.
It's important to note that the design and features of Mesh Belt Furnaces can vary based on specific application requirements and manufacturer specifications. Different variations may include additional features like atmosphere control systems, quenching chambers, or protective gas environments to meet the specific needs of the heat treatment process.
