Description
technical field [0001] The invention relates to the technical field of electrothermal radiant tube processing, in particular to a resistance wire winding device and a winding method for a spiral electrothermal radiant tube. Background technique [0002] The electric heating radiant tube is a device that consumes electric energy and converts it into heat energy to heat the material to be heated. The electric heating radiant tube seals the electric heating element in the protective sleeve. Heat the workpiece. [0003] At present, the inner core of the electric heating radiant tube is mostly composed of axially arranged resistance wires and ceramic support frames. This kind of electric heating radiant tube has a small radiation area and low heating efficiency. Therefore, our company has produced a spiral electric heating radiant tube, such as figure 1 As shown, the spiral radiant tube 100 includes a ceramic tube core 10 and a resistance wire 20, the ceramic tube core 10 includ...
