Radiant tube for high temperature furnace

The radiant heating tube is designed to heat the heating wire or strip and the high-temperature porcelain support directly under the closed high-temperature heat-resistant protective sleeve. The high-temperature heat-resistant sleeve radiates heat to the furnace space and the workpiece to be processed. It is mainly used in heat treatment industrial furnaces for atmosphere protection and various electric heating equipment with relatively high heating conditions. It can be used in the form of flat, sling, plug-in, etc.

The radiant heating element is placed in the protective sleeve. The heat transfer process is different from that of the general open type electric heating element, and the heat shielding is large. Therefore, the electric heating material used in our radiant heating tube has high electrical resistivity and high efficiency electric heating. Conversion rate.

The electric heating radiant tube is made of squirrel-cage, vertical belt and spiral. Our heating elements for high-end electric heating equipment are used according to different needs. Sandvik (kantel) kanthalapm, kanthala-1, kanthalkanthalaf iron chrome Aluminum material or nikrothal80, nikrothal70, nikrothal60 nickel chrome material, outer protection tube for imported kanthalapm tube or Swedish high temperature alloy sheet, gas protection automatic submerged arc welding.

Material Description:                                                                 

The surface load of the radiant heater wire made of kantahl material can reach 3.5~4.0w/cm2 or more. At higher operating temperatures, the use of kanthal materials is superior and has a long component life.

Furnace type power: 2.5kw ~ 1wkw or more; Voltage: 24v ~ 600v or above, when using a series of components made of kanthalaf material, it is recommended to use thyristor to control the heating element.
