Abstract:In the field of zinc ingot casting, it has become a trend to use automated equipment, especially robot, to replace manual slag removal on the ingot surface. In order to improve the operation quality of the equipment, fluid simulation technology was used to model and simulate the automatic slag removal process of, and the effects of slag removal thickness, immersion depth, running speed, tilt angle and surface roughness on the slag removal effect were investigated. The study shows that the best immersion depth is 10~14mm, running speed is 0.06~0.09m/s, shovel tilt angle is 26°~45°. This study provides a useful reference for the design of shovel structure and working parameters, and enhances the stability of slag picking effect, which reduces metal waste and surface quality failure of the ingot.
