Abstract
A bloom 6 is made by bottom casting in a mould 4 and during pouring and solidification of the bloom the upper face of the bloom is covered with an exothermic or insulating medium which slows down or prevents the cooling of the upper face so that cooling and solidification of the bloom proceeds from the bottom upwards. The ratio < IMAGE > is equal to at most 1.3 and for a bloom for producing a flat forging the ratio H DIVIDED D is preferably at most 0.8 while for a bloom for producing a hollow forging the ratio H DIVIDED D is preferably at most 1.2. The bloom may be compressed, drilled to remove segregation from the centre, and forged to produce a hollow article.
