Abstract

The invention discloses a device and a method for preparing a large-size light alloy semi-solid billet, relates to the device and method for preparing the light alloy semi-solid billet, and aims at solving the problem of low speed of the large-size light alloy semi-solid billet prepared by the prior art. An electric furnace 24 is communicated with a stirring cavity 9 through a feed delivery pipe 24-1; a first heating device 10 is wrapped at the outer side of the stirring cavity 9; a round pipe 9-1 is arranged at the bottom of the stirring cavity 9; a second heating device 13 is arranged outside the round pipe 9-1; a mobile work bench 17 is arranged below a baffle plate mechanism 12; a light alloy cast billet is heated through the electric furnace 24; the light alloy cast billet is melted into a liquid state; light alloy liquid slurry is conveyed inside the stirring cavity 9; the light alloy liquid slurry is condensed into semi-solid slurry 20, enters the round pipe 9-1 through a mixing propeller, and enters inside a mobile work bench 17 through the baffle plate mechanism 12, and a semi-solid billet is formed in an air cooling manner. The device and method are used for preparing the large-size light alloy semi-solid billet.

Description

Technical field [0001] The invention relates to a device and method for preparing a light alloy semi-solid blank. Background technique [0002] The semi-solid thixoforming technology is a metal precision forming technology invented by M.C. Flemings and D.B. Spencer of the Massachusetts Institute of Technology in the 1970s. The semi-solid thixoforming technology is a precision and near-net forming technology that inherits the comprehensive advantages of casting and forging processes. Compared with traditional liquid die casting, semi-solid thixoforming technology has the advantages of low forming temperature (liquid-solid phase temperature zone), long mold life, high precision of parts, uniform structure and high mechanical properties; it is comparable to solid forging Compared with that, its significant advantage is that it can form structural parts with complex shapes and mechanical properties close to forgings at a time with smaller force and lower cost. The main technical ro...
