Matters needing attention when heating with direct heating resistance furnace

Attention should be paid when using direct heating resistance furnace for heating:
direct heating resistance furnace

①In order to make the material heated uniformly, the conductive cross section and conductivity of each part of the material are required to be the same;

②Since the resistance of the material itself is quite small, in order to achieve the required electric heating power, the working current is quite large, so the power transmission and the material should be in contact to avoid arcing to burn the material, and the resistance of the power transmission bus should be small to reduce circuit loss;

③When supplying AC power, short network should be reasonably configured to avoid excessive inductance and low power factor.
