Resistance Heating Strip
The Resistance Heating Strip is a flat or ribbon-shaped electric heating element that generates heat when electric current passes through it. It is widely used in industrial furnaces, heat treatment equipment, drying systems, and electrical heating devices due to its stable performance, fast heating response, and uniform heat distribution.
Compared with round heating wires, resistance heating strips offer a larger surface area, improved heat dissipation, and better thermal efficiency.
Danyang Dingfeng Industrial Furnace Co., Ltd. is one of the most reliable manufacturers and suppliers of resistance heating strip in China. If you're going to wholesale durable resistance heating strip made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Product Definition
The Resistance Heating Strip is a flat or ribbon-shaped electric heating element that generates heat when electric current passes through it. It is widely used in industrial furnaces, heat treatment equipment, drying systems, and electrical heating devices due to its stable performance, fast heating response, and uniform heat distribution.
Compared with round heating wires, resistance heating strips offer a larger surface area, improved heat dissipation, and better thermal efficiency.
Working Principle
The strip operates based on Joule heating (resistive heating). When an electric current flows through the high-resistance alloy strip, electrical energy is converted into thermal energy. Due to its flat and wide shape, the heating strip offers a larger surface area compared to a round wire of the same mass. This allows for a lower surface load (watt density), resulting in more uniform radiation, better heat transfer efficiency, and a longer service life. The wavy shape also accommodates thermal expansion and contraction during heating and cooling cycles.
Features
High Heat Efficiency & Surface Area
Flat structure delivers superior radiant heat transfer and faster heating response than round wire elements.
Excellent High-Temperature Resistance
Constructed from FeCrAl or NiCr alloys for continuous operation at 1000℃–1400℃.
Superior Structural Stability
Corrugated design allows free thermal expansion without sagging or collapse, maintaining stable installation gaps.
Strong Oxidation Resistance
Forms self-healing alumina or chromia protective layers at high temperatures to resist continuous oxidation.
Flexible & Easy Installation
Supports hanging, clipping and welding, adapting to box, pit, car-bottom and various furnace sizes.
