ABSTRACT:
A metallic coolant for a metallurgical bath, the composition of the coolant substantially corresponding to that of the bath consists of ball-shaped bodies of sizes not less than 5 mm and not more than 60 mm, preferably 12 to 60 mm, the ball-shape factor B of the coolant having a value of at least 0.57. The ball shape factor (herein defined) relates the shape to that of spherical balls. The coolant can be made, using a hammer mill, from scrap.
