Abstract
The behaviour of die lubricant during casting in die-casting process has not been fully investigated. We added small amount of HCl solution of radioactive H3PO4 to the die lubricant (called “Die Slick”) mechanically and the radiographs of the surface and the inner part of the casting were taken after solidification. Comparatively large amount of radioactive lubricant was applied to the gates of cavities or to the points marked by X in the photo. 1∼8. Zinc alloy ZAC No. 1 was cast in the dies shown in Fig. 1 and 2. The results obtained were as follows:—(1) The lubricant travelled with the flow front of the molten metal through the die cavity and accumulated at the place where the movement of molten metal came to end or remarkable turbulent motion occurred. (2) A large amount of lubricant was entrapped in the casting and distributed comparatively uniformly. (3) The chilled layer of casting occluded hardly any particles of the lubricant. (4) The entrapping of lubricant increased with the rise of casting temperature and with the increase of gate area.
