As a functional alloy that converts electrical energy into thermal energy, resistance ribbon plays a key role in a number of fields. Let’s take a closer look at the properties of resistance ribbons, how they work and their main areas of application.
Materials and properties of resistance ribbons
Resistance ribbons are made of two materials, iron-chromium-aluminium and nickel-chromium alloys, and have the following characteristics:
High Temperature Capability: The maximum working temperature can reach more than 1,000 degrees Celsius, making it suitable for high temperature environments.
Resistance to oxidation: Iron chromium aluminium and nickel-chromium electric heating alloy have strong resistance to oxidation, which enhances the stability in various atmospheres.
Widely used: In metallurgy, construction, military industry, household appliances and other fields, as a key component of various electric heating elements are widely used.
Working principle of resistance ribbon
The working principle of resistance ribbon is based on the thermal effect of electric current. According to Joule’s law, when an electric current passes through a conductor, the amount of heat generated is proportional to the square of the current, the resistance of the conductor, and the duration of the passage of the current. resistance ribbons are designed to take advantage of this thermal effect by converting electrical energy into thermal energy.
Precautions for use of resistance ribbon
As the resistance ribbon may be damaged during manufacture, transport and installation, it is recommended that the user pre-oxidise the ribbon prior to use in order to prolong its service life. This treatment consists of heating the heating alloy element to 100-200 degrees below the maximum operating temperature under power, holding for 5-10 hours, and then cooling slowly.
Diameter and thickness of resistance ribbon
The diameter of the resistance ribbon is directly related to the maximum operating temperature. A larger diameter helps to overcome deformation problems at high temperatures and extends service life. For operation below the maximum operating temperature, it is recommended to keep the diameter not less than 3mm and the thickness of the ribbon not less than 2mm.
Areas of application
Due to their unique functional characteristics, resistance ribbons are widely used in the following areas:
Industrial heating equipment: used in metallurgy, construction, military and other fields of electric heating equipment, such as furnaces, electric furnaces and so on.
Medical field: In some medical equipment, resistance ribbon is used for heating elements, such as thermotherapy equipment.
Chemical industry: resistance ribbon is used in chemical equipment for heating and reaction processes.
Civilian heating appliances: resistance ribbon is widely used as an electric heating device in home appliances, such as electric kettles, electric blankets and so on.
