Shot blasting technology of electric heating wire

Abstract

The invention belongs to the field of processing of electric heating wires, and specifically relates to a shot blasting technology of an electric heating wire. The technology comprises the following steps of (1) preprocessing the surface of an electric heating wire coil rod; (2) premixing shots in a shot blasting machine; (3) feeding the electric heating wire coil rod into a shot blasting chamber;rotating the electric heating wire coil rod at the speed of 1-3 rad / min; adjusting the distance from the shot blasting machine to the electric heating wire, the injecting direction of the shot blasting machine and the shot blasting speed based on the diameter of the electric heating wire; and blasting the shots for 3-10 min; and (4) conveying the electric heating wire coil rod into a cleaning chamber after shot blasting; and cleaning the shots adhered to the electric heating wire coil rod. According to the technology, the surface of the electric heating wire is processed with the shot blasting technology, so that the problems such as low pickling processing efficiency, environmental pollution and the like can be avoided; the diameter of the shot is 0.1-0.5 time that of the electric heating wire; the contact area of the electric heating wire can be increased due to the small diameter of the shots, and thus the shot blasting efficiency can be improved.

However, the surface treatment of electric heating wires still uses pickling process, and the pickling process requires first The oxide layer and oil stain on the surface are removed by pickling, then cleaned, and then dried. This process not only has a long treatment cycle, but also requires the treatment of the used pickling solution. The cost of wastewater treatment is high, and improper discharge will cause environmental pollution
