Abstract

1419852 Making cast iron balls TAIHEIYO KINZOKU KK 1 March 1973 [6 March 1972] 9989/73 Heading B3A [Also in Division B2] A method of making high toughness iron balls comprises casting hypo-eutectic pig iron into a white cast iron block, subjecting the block after heating to hot plastic deformation at a temperature such as to form white cast iron balls having a fine non-network eutectic cementite structure uniformly and concentrically-spherically dispersed throughout a pearlite matrix, rapidly cooling the balls, and tempering them at a temperature below the A c1 point of the cast iron or alternatively annealing them. The hypo-eutectic pig iron is cast into a white cast iron bar by means of a sand or metallic mould or by continuous casting. The bar is placed in a furnace at 1080‹ C. and balls are formed from the bar by a hammer, a freeforging machine or a die-forging machine at 900-1120‹ C. The balls are immediately cooled in water, oil or an air blast and then they are either annealed at 150-250‹ C. or tempered. The cast iron balls ae used in ball mills for grinding cements, ores, coal and the like.
