HEAT TREATMENT BY ELECTRIC RESISTANCE METHOD

The heat-treatment of metals in electric resistance furnaces lends the required mechanical, physical and chemical properties to metallic parts, and increases their strength and load limits, thus improving the quality of machinery and saving materials. 

In electric furnaces the heat treatment in progress is easy to control and automate, the structures being built so as to ensure a uniform distribution of temperature through the work compartment of the furnace in keeping with the technology of heat treatment.
