Detailed explanation of power distribution of box-type resistance furnace industrial electric furnace

According to national standards, industrial resistance furnaces are classified into medium-temperature resistance furnaces, high-temperature box-type electric furnaces with metal heating elements, and high-temperature box-type electric furnaces with silicon carbide heating elements. For small resistance furnaces with a furnace length of no more than one meter, there is a uniform power distribution on the side walls and the bottom of the furnace. For large resistance furnaces, the power will be appropriately increased in areas with large heat dissipation, while the power will be appropriately reduced in areas with small heat dissipation.

When heating the furnace charge, it must be in the air medium. Since there is no mechanized device for discharging, only small batches of workpieces can be used for normalizing, annealing and other heat treatments.

The power distribution of box-type resistance furnaces is widely used in the industrial field. When distributing the power of the resistance furnace, it will be specifically analyzed according to the size of the resistance furnace. Just like this type of resistance furnace is divided into large and small, the power has different distribution methods for different resistance furnaces when distributing.
