Factory Direct Sale Electric Muffle Furnace 1200cfor Heat Treatments

The heat treatment process generally includes three processes: heating, heat preservation, and cooling, sometimes only two processes: heating and cooling. These processes are interconnected and cannot be interrupted. Heating is one of the important processes of heat treatment. There are many heating methods for metal heat treatment, the earliest of which was using charcoal and coal as heat sources, and the recent use of liquid and gaseous fuels. The application of electricity makes heating easy to control and free from environmental pollution. These heat sources can be used for direct heating, as well as indirect heating through molten salts or gold, as well as floating particles.

Metal heat treatment is one of the important processes in mechanical manufacturing. Compared to other processing processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but rather endows or improves the working performance of the workpiece by changing the microstructure inside the workpiece or changing the chemical composition of the workpiece surface. Its characteristic is to improve the internal quality of the workpiece, which is generally not visible to the naked eye. In order to achieve the required mechanical, physical, and chemical properties of metal workpiece, in addition to reasonable selection of materials and various forming processes, heat treatment processes are often essential.
