Description

technical field [0001] The invention relates to a solidification device, in particular to a device for continuously processing alloy solid-liquid interface and alloy melt by super-strong traveling wave magnetic field during directional solidification process of alloy castings. Background technique [0002] At present, the traditional solidification equipment cannot effectively meet the requirements of purifying the alloy melt, eliminating segregation defects, eliminating shrinkage porosity, shrinkage cavity, and ensuring the overall uniformity of alloy castings; moreover, traditional static gravity casting equipment needs to design gates, pouring It is cumbersome and inconvenient to consider the pouring method, pouring gap and feeding pressure. In market applications, due to its complex process, cumbersome operation, low material utilization rate and high industrial cost, continuous automation of industrial production and market cannot be realized. Therefore, traditional met...
