The inner core of the electric radiant tube is composed of resistance wire and ceramic support
frame welded by U-shaped axial end, and there is no shielding between the inner core and the outer
protective sleeve. Rated working temperature of 1000 degrees of electric radiant tube, resistance
wire material for the Cr20Ni80 or 0Cr21Al6Nb, the surface operating temperature up to 1200 degrees,
with this material electric radiation tube maximum working temperature up to 1000 degrees, support
frame is corundum ceramic pieces. The material is 1Cr25Ni20Si2 or 1Cr25Ni35Si2, the high temperature
oxidation resistance of the material is good, the high temperature creep strength is high, has certain
anti-carburizing performance, the radiation tube design and selection safety factor Larger.
Rated working temperature of 1200 degrees of electric radiation tube, resistance wire material for
the 0Cr27Al7Mo2 or steel HRE, the surface operating temperature up to 1400 degrees, with this material
heating radiator short-term maximum working temperature of 1250 degrees, the support frame is steel
jade porcelain Pieces. The material is Fe-Ni-Cr-Al-Re alloy, the material has a high anti-oxidation
ability, in the oxidizing atmosphere of 1300 degrees can be long-term work, 1360 degrees short-term
anti-corrosion resistance, Oxidation. Applicable to high temperature and low oxygen partial pressure
and containing S, C environment work.
The factory development and production of electric radiation tube in addition to the domestic heat
treatment equipment manufacturers supporting, but also for users to design and manufacture of
non-standard products of the heater, according to the use of the situation can be divided into:
heat-resistant steel seamless tube, Welded pipe, centrifugal casting pipe and non-metallic casing.
High temperature electric radiant tube Features:
1, the use of high-quality raw materials for the production of seamless cold-drawn steel
(the highest temperature of 1200 degrees) manufacturing
2, the core with a resistance wire U-shaped axial end of the welding method
3, resistance wire and ceramic frame is basically no shielding, resistance wire and furnace
temperature difference is small
4, the maximum operating temperature of 1000 degrees or 1200 degrees
5, the company's radiation tube is the biggest advantage of the choice of seamless cold drawn,
thin-walled heat-resistant steel pipe (1Cr25Ni20Si2 or 0Cr25Ni20Si2), the thermal radiation of its
products than similar products 10%
6, the use of more than 8000h
