Embodiment

[0074] By using the pressure solidification molding device and method for suspension manufacturing provided by the present invention, the spherical casting mold of Al droplets under the condition of electromagnetic suspension can be obtained.

[0075] (1) Selection of mold and mold movement mode: the experimental requirement is to design a spherical casting with r=20mm, design a spherical mold that can be die-cast, and choose one-sided mold to fix,

[0076] (2) Calculation of falling time: In a specific device, the radius of the melt is 0.023m, and the vertical distance between the first detector 5 and the axis of the mold is h 1 =0.5m, the vertical distance between the second detector 6 and the axis of the mold is h 2 =0.35m, then the time passing through the second detector is about t 1 =0.173s, the time required for falling to the mold center is 0.316s.

[0077] (3) Determine the moment to trigger the mold movement: unilateral mold movement. From the formula 7, it can be ...

Abstract

The invention discloses a pressure solidification forming device and method for suspension manufacturing, and relates to the technical field of liquid metal solidification forming. Through the combination of electric magnetic suspension technology, pressure solidification forming technology, photoelectric detection technology and a control system, accurate positioning of melt and timely response of mold movement are achieved, and pressure solidification forming of an alloy casting with excellent performance is achieved. According to the device, a melt position detecting system can accurately capture position and speed of the melt, and adjust the mold movement by using a controller according to the position information of the melt so as to facilitate the accurate forming of the high-speed falling melt; and the direct solidification forming of the large-volume metal melt is achieved by the pressure solidification forming device, so that the process flows such as the refining preparationof raw material, the active control of solidification process, and the direct forming of the material are integrated.

Description

technical field [0001] The invention relates to the technical field of liquid metal solidification forming, in particular to a pressure solidification forming device and method for suspension manufacturing. Background technique [0002] At present, the electromagnetic levitation containerless treatment technology is widely used in the fields of new material preparation, high-purity metal smelting and material solidification, etc. It has the characteristics of good stability, strong levitation force, and simultaneous levitation and heating. The preparation of the melt avoids contact with the crucible and the pollution is small. Combined with a variety of cooling methods, the microstructure under the supernormal solidification condition can be obtained. At the same time, the electromagnetically suspended liquid drop itself is in the high-frequency magnetic field generated by the coil, and the obtained Lorentz force produces violent electromagnetic stirring, which is enough to ...
