Abstract

The invention provides a semi-solid continuous pulping system. The semi-solid continuous pulping system comprises a large quantitative holding furnace, a small quantitative holding furnace, a stirringdevice and a die-casting island, wherein an extraction pipeline is arranged between the large quantitative holding furnace and the small quantitative holding furnace; and a conveying pipeline is arranged between the small quantitative holding furnace and the die-casting island. Alloy melt is extracted into the small quantitative holding furnace from the large quantitative holding furnace, the small quantitative holding furnace is used for improving the holding precision, and the pipeline is used for extracting to transfer and transport pulp, so that related mobile transportation equipment such as soup feeding in a conventional pulping process is reduced, the preparation cost is reduced, and the operation is simple; and the semi-solid preparation method can be used for continuously pulping, so that the pulping time is greatly saved, and the production and preparation efficiency is improved; and moreover, the method can be used for extracting relatively pure alloy melt for pulping, so that relatively high-quality die-casting parts are obtained.

Description

technical field [0001] The invention mainly relates to the technical field of semi-solid preparation, in particular to a semi-solid continuous pulping system. Background technique [0002] Semi-solid metal processing is the metal in the solidification process, strong stirring or by controlling the solidification conditions, inhibit the growth of dendrites or break the dendrites generated, forming an equiaxed, uniform, fine primary phase, which is evenly distributed in the liquid phase Suspended semi-solid slurry, this slurry still has good fluidity when the solid phase ratio reaches 60% under the action of external force. [0003] At present, the commonly used method in the preparation of semi-solid slurry is to place the alloy melt in a large-quantity holding furnace, use a crucible or ladle to hold the alloy melt, and move the crucible or ladle by moving the connecting rod. Stirring at the mixing equipment, and then transported to the die-casting equipment for molding, wh...
