Abstract: Based on the policy of energy saving, emission reduction and electric energy replacement in the 14^th Five-year Plan of The People’s Republic of China, a more energy saving, safe and efficient alternative scheme of metal fiber felt electric film was proposed to replace traditional coal-fired heating and carbon heating. The static resistance characteristics, dynamic electrothermal characteristics and aging characteristics of stainless steel metal fiber sintered felt and needled felt were studied experimentally. The resistance-temperature characteristics of sintered felt electrothermal film are stable and the temperature response characteristics are good. Needled felt electrothermal film has higher resistivity, better electrothermal conversion effect, uniform temperature distribution and good aging characteristics.
