Hexin Machinery has a professional design and all kinds of high, medium and low temperature radiant tube, radiant tube is enclosed in protective sleeve inside electric heating elements of ohmic heating, indirectly by the sleeve lining and heat radiation heats the workpiece in the form of a squirrel-cage, vertical and spiral and so on. Heating core components used Nickel-chromium wire, and nickel chrome with, and iron chrome aluminum silk, and iron chrome aluminum with, and casing used seamless tube, and volume business pipe, and centrifugal casting tube and non-metallic dedicated make carburizing casing,, has resistance rate stable, anti-oxidation performance good, high temperature strength high and good of processing performance and the can welding sex, using life long, advantages, widely used in heat treatment industry of various kinds of heating furnace.
matters need attention :  1 radiant tube during use to periodically check the leads to the terminals of loose oxide bolt should be tightened. 2, do not touch when charging and discharging the radiation tube. 3, radiant tubes in use for some time after taking the tube, it tubeturn used after the dust. 4, against extremely mild overload for a long time.
