Technical Field
The invention belongs to the technical field of magnesium alloy rolling, and particularly relates to a process method for cast rolling-rolling integrated production of a magnesium alloy section.
Background
In recent years, China has been greatly developed in the magnesium industry, and is just like to be a strong world industry nation. The magnesium alloy pipe, rod, plate and special-shaped material have important application value and wide application prospect in the fields of automobiles, electronics, aviation, aerospace and the like. In addition, magnesium alloy profiles are becoming increasingly attractive to industries that use structural applications extensively, particularly in the automotive industry. However, the magnesium alloy has poor processability and high temperature sensitivity, and the complex production process increases the processing difficulty of the magnesium alloy section. Currently, two major obstacles to the industrial application of magnesium alloy components are the high manufacturing costs and the cumbersome processes resulting from poor formability. Under the condition of room temperature, the performance of the magnesium alloy section formed by bending is poor, and the magnesium alloy section is mainly characterized by unstable size, poor forming quality, distorted section shape and large rebound quantity. The structure of the magnesium alloy obtained after thermal deformation is more uniform, the comprehensive mechanical property is better improved, and the mechanical property of the obtained magnesium alloy product is higher than that of a cast product.
The traditional magnesium alloy section bar mainly adopts an extrusion process: the magnesium alloy ingot is subjected to solution treatment and then passes through a lathe carriage, and defects of hot cracks, serious reduction of surface quality and the like of an extruded piece can be caused if the extrusion speed is not proper during extrusion. The magnesium alloy section manufactured by the traditional extrusion process has the advantages of complex process, low processing efficiency, larger period and cost, and difficult satisfaction of the requirement of industrial mass production of the magnesium alloy section.
