Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of casting detection equipment, and particularly relates to a tool for making a molding sand refractoriness test sample. Background Art
[0002] During the lost foam casting process, the sandbox is filled with silica sand to form a fixed pattern. Molten iron is poured into the sandbox, causing the EPS pattern to vaporize, fill the mold, and solidify into a metal shell. The entire casting process requires the silica sand to have sufficient refractoriness to withstand the high temperature of the molten iron, preventing it from melting and adhering to the casting surface, causing casting defects. Therefore, whether the refractoriness of the silica sand meets technical requirements is a key factor affecting the quality of the casting. Therefore, testing the refractoriness of silica sand is considered a key quality control measure in the foundry industry. Currently, different companies in the industry use different testing equipment and methods to meet their respective testing requirements, resulting in significant variations in efficiency and convenience.
