Title:
CUTTING AND BREAKING DEVICE FOR HOMOGENIZING AND REFINING METALLIC MELTS AND RHEOLOGICAL FORMING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/180362
Kind Code:
A1
Abstract:
Disclosed is a cutting and breaking device for homogenizing and refining metallic melts, comprising a cutting blade mechanism, a stirring cavity (8), a liquid level protection cover (3) or an upper blocking port (24), a coupler (4), an additive mechanism (41) and an electric motor (6). The cutting disk mechanism provided in an axial direction of the stirring cavity (8) comprises a cutting blade (1) and a rotating shaft (2), and the cutting blade (1) is mounted on the rotating shaft (2); the rotating shaft (2) and the electric motor (6) are connected via the coupler (4); the liquid level protection cover (3) or the upper blocking port (24) is provided below or above a melt liquid level (10) inside the stirring cavity (8). The cutting blade (1) is a type of knife, having a sharp rotating front end, and an inclined, plane or curved side surface. The device may further comprise a movable rail (7) or a lifting platform. The rotating shaft can also reciprocate up and down in the axial direction while driving the cutting blade to rotate at a high speed inside the stirring cavity, and is able to generate a "controllable turbulence" as well as a "cutting and breaking effect", such that all solute inside the melts is highly dispersed and homogenized, thereby obtaining a homogenized, fine and excellently compacted casting solidification structure. Further disclosed is a cutting, breaking and rheological forming method for homogenizing and refining metallic melts.
