Abstract

The invention discloses a device for preparing a semi-solid sizing agent. The device comprises a die-casting soup ladle, a mechanical stirring rod, a first stirring blade, a second stirring blade, a compressed air generator and a compressed air flow pipe, wherein the mechanical stirring rod is in a hollow structure; a first end of the compressed air flow pipe is connected with the compressed air generator; a second end of the compressed air flow pipe is inserted into the mechanical stirring rod; the first stirring blade and the second stirring blade are respectively arranged on the mechanical stirring rod; the mechanical stirring rod is inserted into the die-casting soup ladle. The invention also discloses a method for preparing the semi-solid sizing agent by using the device. The method comprises the following steps: putting the molten alloy into the die-casting soup ladle; stirring the molten alloy while introducing the compressed air into the stirring rod; and controlling the quality of the semi-solid sizing agent by controlling the related parameters. According to the device and technique, the preparing efficiency for sizing agent is high and the quality of the semi-solid sizing agent is excellent.

Description

technical field [0001] The invention relates to the field of semi-solid die casting production, in particular to a device and method for preparing semi-solid slurry. Background technique [0002] Semi-solid metal casting technology has experienced more than 20 years of research and development. This technology is a metal forming technology between solid forming and liquid forming. It has low liquid forming flow stress, high forming speed, and can form complex shapes. The advantages of the components are therefore widely concerned. The preparation technology and method of semi-solid slurry directly determines the quality and cost of semi-solid casting products, and is the key to semi-solid casting. [0003] At present, there are many preparation processes for semi-solid slurry, such as mechanical stirring method, electromagnetic stirring method, controlled solidification method, strain activation process, powder metallurgy method, etc., but these methods all have certain pro...
