Product Description

Porcelain Heater Ceramic Bobbin Resistors for Electric Furnace

Electric ceramic heating radiant tube is characteristic by excellent oxidation resistance and very good form stability resulting in long element life.they are typically used in electrical heating elements in industrial furnaces and home appliances.The inner core of the electric heat radiant tube is composed of the u-shaped axial array end welded resistance wire and ceramic support frame.

There is no shield between inner core and the outer protective sleeve.It has good cooling function, the rated working temperature of electric heating radiant tube is 1000 degrees.The material of resistance wire Cr20Ni80 or 0 cr21Al6Nb. lts surface temperature can reach 1200 degrees.The highest working temperature of this kind of electric heating radiant tube can reach1000 degrees.

The frame use high alumina ceramic.The outer protective casing is made of cold drawing seamless thin-wall heat-resisting steel,its material is 1Cr25Ni35Si2 or 1Cr25Ni20 Si2.The material has high temperature and good oxidation resistance,better high temperature creep strength.

The main technology and performance of ceramic radiant tubes with resistance wire:
1. Range tolerance of cold resistance of electric wire ≤3%
2. Insulation resistance between outside protector and electric resistance >2MΩ
3. Diameter of heater tube is from φ60mm~φ300mm
4. Power is from 2KW to 24kw
5. Length of heater tube is from 800 to 2800mm
6. Thickness of sleeve is from 1.5 to 16mm
Application:
1. Metallurgical industry
2. Heat treatment furnaces
3. Auto parts and accessories
4. Medical Instrument parts
5. Pipe Fittings or pipeline accessories
6. Other industry metal casting parts...

If with protection, it's cold drawing seemless thin thickness stainless steel tube, the material is Fe-Ni-Cr-Al-Re alloy, this material has super high-temperature oxidation-resistance, carburization resistance and high temperature strength; and woke on 1300 degrees for long time , anti-oxidation on 1360 degrees for short time.

Usage of Industrial sewing machine bobbins:
1. Avoid to heat over the temperature and overload for long time
2. When the furnace temperature higher than 400 degrees, avoid to be cold immediately.
3. Unload and load the material can't touch the ceramic heater
4. Pay attention to the red and blue buttons when the furnace on work, and change regularly when on thermal insulation
5. Pay attention to the instrument meter, and deal with in time when the furnace temperature is not matched with the meter.
6. The furnace Capacity over 100KW, it'll be better to fix the ammeter for check in every heat area.

Protection:
1. After using three to four months, take the ceramic heater, and pour-out the dust in the ceramic heater, and tuner the heater 180 degree.
2. Pay attention to the positive and negative pole, and two to four months make a change.
3. Can touch and hit the heater when take it out.
4. Check the screw regularly for the oxidation looseness,
