Problems solved by technology

But its disadvantages are the same as electromagnetic stirring technology, high energy consumption and high cost
The above three methods have not yet entered into large-scale industrial production, and there is still a big gap between production efficiency and product quality compared with European and American countries

Abstract

The invention discloses an opposite-opening totally-closed melt confined flow induced nucleation semi-solid slurry preparation device, and belongs to the technical field of material processing. The device comprises an upper cooling plate and a lower cooling plate, after the upper cooling plate and the lower cooling plate are combined, a melt confined flow induction nucleation channel is formed between the upper cooling plate and the lower cooling plate, a feeding port is formed in the upper end, and a material receiving crucible is arranged at the lower end. The device can prepare semi-solid alloy slurry which is uniform and fine in structure and better in spheroidizing effect, alloy melt is directly poured into a melt constraint induction nucleation device through the feeding port, the melt constraint induction nucleation device is welded with an upper water tank and a lower water tank which are provided with an independent water inlet and an independent water outlet, under the combined action of the strong chilling action on the contact surface of the constraint induction nucleation device and the restraining action in the horizontal and vertical directions, semi-solid slurry in the shape of fine spheres or roses can be prepared. The device can be used for semi-solid rheoforming of alloys such as copper, aluminum and magnesium, and the process is simple in process, convenient to operate and low in cost.

Description

technical field [0001] The invention relates to a split-type fully-enclosed melt-constrained flow-induced nucleation semi-solid slurry preparation device, which belongs to the technical field of material processing. Background technique [0002] Semi-solid metal processing technology is that during the solidification process of metals, the formation of dendrites is suppressed or broken by controlling the solidification conditions, and the dendrites generated are formed to form equiaxed, uniform, and fine primary phases that are evenly distributed in the liquid phase. The semi-solid slurry is processed and formed by conventional techniques such as die-casting, extrusion, and die forging. At present, there are many methods for preparing semi-solid slurry, such as mechanical stirring method, electromagnetic stirring method, near liquidus casting method, ultrasonic vibration method, inclined plate method, etc. [0003] The principle of mechanical stirring technology is to use t...
