Process and equipment for manufacturing wide-width magnesium alloy plate in coils

Abstract

The invention relates to the technical field of process and equipment for a new non-ferrous metal material and discloses a process and equipment for manufacturing a wide-width magnesium alloy plate. In the process, an as-cast rod material is subjected to milling face scaling, multi-axis forging, machining, high-temperature ageing, heating, extruding, flattening and coiling to finish the coiling production of the wide-width magnesium alloy plate. The equipment comprises a multi-axis forging machine, an extruding machine, a flattening machine and a coiling machine; the extruding machine, the flattening machine and the coiling machine are arrayed along a discharging axis of the magnesium alloy plate and are controlled by a synchronous control system, wherein the extruding machine is internally provided with a semi-circular or wavy arc-shaped extruding and distributing module; and a rod material heater is arranged at the inlet end of the extruding and distributing module. According to the invention, by utilization of the small-tonnage extruding machine and a mould in which an arc line between two points is longer than a straight line between the two points, the wide-width magnesium alloy plate which is larger than the size of the outlet of the extruding machine is produced in coils through an arc surface rolling and flattening machine for flattening an arc surface. The coiling production of the wide-width magnesium alloy plate can be finished with smaller investment.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal material processing and equipment, in particular to a process and equipment for producing wide-width magnesium alloy strips in coils. Background technique [0002] Magnesium is one of the most abundant elements on the earth. In current engineering applications, it is the metal material with the lightest mass (1.74g / cm3) and the highest specific strength. Compared with light engineering plastics, magnesium alloys have higher elasticity and Plastic deformation ability; compared with aluminum alloy (2.8g / cm3), magnesium alloy is not only light, but also has high anti-vibration and noise reduction ability, and has strong corrosion resistance, electromagnetic shielding performance, radiation protection performance, recycling rate Advanced advantages. Therefore, it is the most ideal and practical lightweight structural material in pillar industries such as transportation (automotive), aerospa...

It is not suitable for continuous production in rolls

[0007]2. Finish rolling after extruding the billet. The advantage is that the material structure is good, it is easy to realize continuous production and supply in coils. The disadvantage is that the one-time investment is large, Shape control is difficult

[0008] It can be seen that the high cost caused by high investment in process equipment, low-efficiency production, and low yield limit the mass application of high-performance magnesium alloy rolled sheets
