Radiation tube not only for domestic high-end electric processing equipment manufacturers and end-users supporting, and is the export of heat treatment equipment on the matching products. Radiation tube tube with cage frame, vertical winding, resistance wire around the type, the resistance wire using nickel-chromium, iron-chrome aluminum alloy material, jacket tube with seamless pipe, roll pipe and centrifugal pipe The General effective length: 550 ~ 3600; general casing diameter: φ50 ~ φ280. Single power: 1.5kw ~ 75kw; single voltage: 24v ~ 380v.
The series of products for the implementation of bright quenching, normalizing, carburizing, carbonitriding multi-purpose furnace and swivel, mesh belt, casting, continuous and other industrial heating.
First, the overview of electric heating radiant tube
1, wire-mounted spiral around the electric radiation tube
This heat radiating tube consists of heat-resistant alloy steel casing and heater, the heater generally by φ3-5 mm electric wire around the helical groove in the heat-resistant insulation ceramic die, the working voltage of 220V, power generally 5 -7KW.
2, ribbon spiral around the electric radiation tube
The structure of the heater is basically the same as the structure, except that the heating element is wound with a resistive tape. The resistive tape has a thickness of 1-3 mm and a width of 10-20 mm. The die is also composed of a plurality of grouping dies , In the same surface load, the heat radiation surface, the material can be saved, the general high-power point heating radiant tube in this form.
3, axial wave folding cage cabinet electric heating tube (commonly known as squirrel cage)
Its structure is the heating element resistance wire (belt) bent into "U" -shaped string into a number of high temperature resistant ceramic support plate, the middle with a heat-resistant rod fixed, the general effective length: 900 ~ 2400; Tube diameter: φ80 ~ φ280. Single power: 2kw ~ 40kw; single voltage: 30v ~ 220v. This radiant tube has a longer life span.
Second, the characteristics of electric heating radiant tube
1, practical and reliable. I plant products to users after production verification, reliable and durable quality.
2, the core material using DC argon arc welding, the surface load, resistance and other technical indicators are guaranteed.
3, heat-resistant insulation material is the German formula, the porcelain pieces of thermal shock, high temperature, long life, good surface quality.
Electric radiant tube, with high, medium and low temperature furnace and special atmosphere furnace specifications arbitrarily selected. Outer casing with seamless high temperature alloy pipe and coil, centrifugal cast pipe, non-metallic anti-carburizing tube and so on. And according to the radiant tube heating element in a variety of atmospheres and harsh cycle conditions, the general resistance alloy can not be applied.
Third, the advantages of electric radiation tube is
1, installation, testing, easy maintenance, are carried out in the furnace. No need to shut down or cool the furnace temperature to repair and replace the electric heating device. Under normal production conditions, the replacement only takes about 10 minutes, greatly reducing labor intensity and improving productivity. 2, compact structure, stable performance, single power, life is several times the ordinary electric heating pipe.
