Infrared heating furnaceThere are significant differences between electric heating furnaces and electric heating furnaces in terms of heating principles, heating efficiency, applicability, safety, and environmental friendliness. The following is a detailed introduction for you:
Heating principle
Infrared heating furnaceBy utilizing the principle of infrared radiation, infrared radiation is emitted directly onto the object being heated. Infrared radiation has strong penetration ability, which can be absorbed by objects and converted into heat energy, causing objects to heat up from the inside. For example, in food drying, infrared radiation can penetrate the surface of the food, causing internal moisture to evaporate.
Electric heating furnace: mainly relies on current passing through heating elements such as resistance wires to convert electrical energy into heat energy, and then transfers the heat to the heated object through convection, conduction, and other methods. For example, the common resistance furnace heats the air inside the furnace by heating the resistance wire, and then heats the workpiece placed inside the furnace.
Heating efficiency
Infrared heating furnace: With high energy utilization efficiency, infrared directly acts on objects, reducing energy loss in the intermediate heat transfer process. It has a fast heating speed and can quickly reach the desired temperature. For example, in some industrial drying processes, infrared heating furnaces can shorten the drying time compared to traditional electric heating furnaces.
Electric heating furnace: Due to the need to transfer heat to objects through heat conduction, convection, and other methods, there will be some energy loss during the process, and the heating speed is relatively slow. For example, for heating some large workpieces, an electric heating furnace may take a long time to uniformly raise the overall temperature of the workpiece.
Scope of Application
Infrared heating furnace: suitable for occasions that require high heating speed, rapid surface heating, or certain requirements for thermal uniformity, such as plastic processing, food drying, printing industries, etc. In plastic processing, infrared heating furnaces can quickly heat the surface of plastics to achieve a plastic state.
Electric heating furnace: With a wide range of applications, it can be used for heat treatment, melting, sintering and other processes of various metal materials, as well as experimental and production processes that require high temperature control accuracy. For example, in metal heat treatment, an electric heating furnace can precisely control the heating temperature and holding time to ensure the performance of the metal.
Safety and Environmental Protection
Infrared heating furnace: usually has good safety, infrared itself does not produce open flames, reducing fire hazards. Meanwhile, infrared heating furnaces have relatively low energy consumption, produce fewer pollutants, and are environmentally friendly.
Electric heating furnace: Safety depends on its design and usage. If the heating element ages or the circuit has problems, it may cause safety accidents such as fires. In addition, electric heating furnaces may produce some harmful gases during the heating process, such as resistance wires reacting with oxygen in the air at high temperatures, producing small amounts of oxides.
