What are radiation tubes made of?
At present, the current production of radiation tubes are basically heat-resistant steel, using centrifugal casting process. Radiation tube: the wall temperature is generally 50-100℃ higher than the workpiece processed in the furnace. Both materials are used at relatively high temperatures. Therefore, the temperature of different heat-resistant steel varies with the environment and control atmosphere. In the case of high furnace temperature, high temperature resistant fishing steel is difficult to meet the technological requirements. We need to choose other materials to make radiators. With the improvement of radiation tube materials, the extension of life and the improvement of overall performance, foreign countries have developed higher quality radiation tube, including aluminum plated low-carbon seamless steel tube, ceramic tube, SiSC composite material and other new radiation tube.
What is the difference between radiation tube and electric heating tube?
Radiating tube is heat transfer by radiating light wave/electric heat pipe, can transfer heat to a variety of media. The heating body is air: the efficiency of the radiation tube is higher than that of the electric heating tube. Radiator life is relatively short, but life is short.
What are the advantages of radiant tubes?
Cold radiating tube heating element is a kind of heating element used in drying furnace and kiln. Compared with the general electric heat pipe components, its advantages are:
1. Installation, testing, maintenance are very convenient, completely outside the furnace. No need to turn off or cool the furnace for maintenance and replacement of heating equipment. Under general production conditions, the replacement work time is about 10 minutes, which greatly reduces labor intensity and improves production efficiency.
2. Compact structure, stable performance, single power, service life is several times the general electric heat pipe. It is an ideal new product for tunnel kiln drying equipment.
What is an electric radiation tube?
The electric radiation tube is to convert the lost electric energy into a heat source, which is used to electrically heat the articles needed for electric heating. At work, the electric heating tube low temperature fluid medium is the use of heat transfer channel and its input quantity, the electric heater within the specified in hot runner, using the basic principle of electric heat pipe air fluid thermodynamics design route, will air electric heating tube electric heater of high temperature heat away at work, make the air electric heating pipe for heating medium temperature, Electric heat pipe to obtain process requirements of high temperature medium.
 
What are the classifications of electric heat dissipating tubes?

1. The helix is wound on the electric radiator tube.

The electric radiant tube consists of a high temperature resistant alloy housing and a heating furnace, usually with a heating wire wound around a spiral groove shaped high temperature resistant insulating ceramic tube core.

2. The ribbon spiral is wound on the electric radiator tube.

The structure of the utility model is basically the same as that of a structure, except that the electric heating element is wound with a resistance belt, and the tube core is composed of multiple groups. Under the same surface load, the thermal radiation surface is large and the material is saved. The general high-power point electric heating radiation tube adopts this form.

3. Axial corrugated cage type electric heating radiation tube (commonly known as squirrel cage type electric heating radiation tube)

The structure of the utility model is to fold the resistance strip of the electric heating element into a "U" shape and string it into a plurality of insulating and high-temperature resistant ceramic supporting disks, and the middle is fixed with a heat-resistant rod. The radiation tube has a long service life.
