The inner core of the electric heating radiant tube is composed of a U-shaped axially arranged electric wire and a ceramic support frame welded at the end. There is no shielding between the inner core and the outer protective sleeve, and the heat dissipation is good. The electric heating radiant tube has a rated working temperature of 1000 degrees. The material of the electric wire is Cr20Ni80 or 0Cr21AI6Nb. The surface working temperature can reach 1200 degrees. The maximum working temperature of the electric heating radiant tube using this material can reach 1000 degrees. The support frame is a high-aluminum ceramic part. . The outer protective casing is a cold-drawn seamless thin-walled heat-resistant steel pipe made of 1Cr25Ni20S12 or 1Cr25Ni35S12. This material has good high-temperature oxidation resistance, high high-temperature creep strength, and has certain carburization resistance. The design and material selection of the radiant tube have a safety factor. larger.
Features of high temperature electric heating radiant tubes:
1. Made of seamless cold-drawn heat-resistant steel pipes (maximum temperature 1200 degrees) produced from high-quality raw materials
2. The inner core adopts U-shaped axial arrangement of resistance wire and end welding method.
3. The resistance wire and ceramic frame are basically unshielded, and the temperature difference between the resistance wire and the furnace is small.
4. The maximum working temperature is 1000 degrees or 1200 degrees. 5. The biggest advantage of the radiant tubes produced by our company is that it uses seamless cold-drawn, thin-walled heat-resistant steel tubes (1Cr25Ni20Si2 or 0Cr25Ni20Si2). The thermal radiation of its products is 10% higher than similar products. 6. Use more than 8000h
Radiant tubes have the following advantages:
(1) It can ensure the controllability of the atmosphere in the furnace;
(2) Temperature control, installation and maintenance are more convenient and easy to seal;
(3) Since there is no muffle tank in the furnace, the furnace volume is expanded and the production capacity is improved;
(4) Strong heating capacity and high efficiency;
(5) Heat-resistant steel is saved.
Use
(1) Prolonged over-temperature and over-load use is prohibited;
(2) When the furnace temperature is 400°C, rapid cooling is not allowed;
(3) Do not touch the radiant tube during loading and discharging;
(4) When the furnace is working, always pay attention to whether the traffic lights on the control panel are normal. During heat preservation, the traffic lights must be replaced after a period of time to avoid burning the radiant tube due to failure of the control switch; (5) Pay attention to the working condition of the instrument at any time. If you find that the furnace Abnormal temperature and instrument indications must be analyzed and dealt with in time; (6) For furnaces with a capacity exceeding 100KW, it is best to install an ammeter for inspection in each heating zone. An ammeter should be installed for each phase of the three-compartment high-temperature electric furnace.
