High Heat Resistance Cordierite Ceramic Bobbin Core Heater for Industrial Electric Furnace

Product Description

Product Description

Product Features:
1. Seamless cold-drawn heat-resistant steel pipe (temperature is 1200ºC) made of high-quality raw materials.
2. The inner core is welded with the ends of U-shaped axial arrangement of resistance wires.
3, the resistance wire and the ceramic frame are basically shielded, and the temperature difference between the resistance wire and the furnace is small.
4. Operating temperature is maximum to 1500 degrees
5. The biggest advantage of the radiant tubes produced by our company is that seamless cold-drawn thin-walled heat-resistant steel tubes (1Cr25Ni20Si2 or 0Cr25Ni20Si2) are selected, and the thermal radiation of its products is 10% higher than that of similar products.
6. The service life of more than 8000 hours.
 

Characteristics & Advantages

Common faults in use and troubleshooting methods.

NO.	Fault phenomenon	Cause	Troubleshooting Methods
1	component short circuit	1. The resistance wire contacts the steel pipe	1. The resistance wire should be annealed and tied tightly.
		2. Improper transition of the resistance wire between the two core tubes	2. Adopt a reasonable transition method
		3. The heat-resistant core tube or porcelain plate is broken	3. Choose the right material and be careful not to break it
		4. Too much oxide scale falls to the bottom of the pipe	4. Place refractory bricks at the bottom of the pipe
			5. Material size is within the control range
2	The core tube or porcelain tube is broken	1. The quality of heat-resistant porcelain is poor	1. Pay attention to the quality of porcelain parts
		2. The flame contacts the porcelain parts during gas welding	2. Avoid flame contact with porcelain parts
		3. Severe collision or vibration during installation	3. Avoid collision and vibration
		4. Heating too quickly during use	4. Choose the right materials and improve the structure
3	Radiant tube cracking	1. Poor welding materials	1. Choose the right welding materials
		2. Improper welding operation	2. Welding according to specifications
4	Radiant tube deformation	1. The material of the radiation tube is not good	1. Choose materials
		2. Improper hanging or thermal stress deformation	2. Hang correctly. If there is any deformation, take timely measures
		3. Horizontal placement, improper force	3. When placed horizontally, a support frame should be provided
