Why does the mesh belt furnace heat up slowly?

Mesh belt furnace is a kind of heat treatment equipment for continuous heating treatment, which needs to be heated slowly during the heating process. The main reasons are as follows:

1. Avoid thermal stress: the workpiece in the mesh belt furnace will expand when heated, and the expansion degree of different parts may be different, which will produce thermal stress. If the temperature rises too fast, the thermal stress will increase, leading to problems such as deformation and cracking of the workpiece. Therefore, slow heating can avoid or reduce the generation of thermal stress.

2. Ensure the quality of workpiece: mesh belt furnace is usually used to heat metal materials, such as annealing and quenching. If the temperature rises too fast, the temperature difference between the surface and the interior of the workpiece may be too large, thus affecting the quality and performance of the workpiece. Therefore, slow heating can ensure that the workpiece is heated evenly, thus ensuring the quality and performance of the workpiece.

3. Safe operation: mesh belt furnace usually uses high temperature heating. If the temperature rises too fast, it may cause safety problems, such as high temperature in the furnace and damage to hot spots. Therefore, slow heating can ensure safe operation and avoid safety accidents.

To sum up, the mesh belt furnace needs to be heated slowly, mainly to avoid thermal stress and ensure the quality of the workpiece and the safety of operation. In actual operation, the heating rate should be set reasonably according to the specific situation to ensure that the workpiece can be effectively heated.
