Abstract

The invention relates to an alloy workpiece casting method, and discloses a casting technological method of a large-size magnesium alloy flat structural component. The method comprises the first step of preparation before casting and the second step of smelting casting, and further comprises the steps such as adopting sand casting as a casting method, carrying out gravity casting, carrying out upper and lower two-box modeling, adopting a solvent method for alloy smelting, and carrying out gravity casting. High-quality casting of the large-size magnesium alloy flat structural component is achieved, various indexes of the structural component meet design requirements, and the beneficial effects that no crack or shrinkage cavity defect is produced, and the interior quality and fluorescence detection meet requirements of I-type castings are achieved.

Description

technical field [0001] The invention relates to a casting process method for large-size magnesium alloy flat structural parts, specifically aimed at casting magnesium alloy structural parts, through reasonable design of gating system, feeding riser, and pouring parameters, high-quality, defect-free castings are obtained . Background technique [0002] Compared with iron and steel materials, cast magnesium alloys have the characteristics of small volume and mass, high specific strength, good corrosion resistance, good cutting performance and excellent casting performance. In order to reduce structural weight and improve product performance, more and more parts are made of lightweight materials. Magnesium alloys are more and more widely used in aerospace, and the demand for large magnesium alloy parts is also increasing. . [0003] For large-scale magnesium alloy flat structural parts, which are large in size and thin in wall thickness, and are usually Class I castings, the ...
