Abstract

The invention relates to a method for continuously extruding and molding zinc alloy structural materials, belonging to the technical field of plastic molding of zinc alloy tubing, section bar and wire stocks. In the technology, the plastic processing performance of zinc and alloy thereof can be dramatically improved by the method of modified fine grain strengthening and polishing, and deformation strengthening-great cutting deformation mode is in favor of refining crystals. Sufficient extruding force and heat quantity can be generated by utilizing strong friction of the continuously extruding technique on the zinc alloy structural material stock such as rod materials, granules or molten metal and the like and the rotary extruding wheels of the extruding device, thus directly extruding the zinc alloy structural material stock into finished products by the great cutting deformation mode. The invention solves the problems of long flow, high energy consumption caused by multiple heating, low material utilization rate, high production cost and the like existing in the current conventional techniques.

Description

technical field [0001] The invention belongs to the technical field of plastic forming of zinc alloy pipes, profiles and wires, and in particular relates to a continuous extrusion forming method for deformed zinc alloy structural materials. Background technique [0002] Zinc and zinc alloys have the characteristics of excellent atmospheric corrosion resistance, applicable mechanical properties, good electromagnetic field properties, suitable chemical properties and excellent process properties, low melting point, low energy consumption, and low production cost. At present, people's attention to zinc alloys is mainly focused on the application in the casting field. Except for superplastic zinc alloys that have attracted people's attention, other deformed zinc alloy structural materials have not been involved, so the application of zinc and zinc alloys is limited. Later, it was discovered that titanium has a good effect on refining and strengthening the structure of zinc alloy...
