Abstract

1,224,313. Metal pouring ladles. INTERNATIONAL MEEHANITE METAL CO. Ltd. 16 Feb., 1968 [2 March, 1967], No. 9865/67. Heading F4B. [Also in Division C7] A ladle used for treating molten metal with volatile additives has a chamber at its base into which the additive is initially placed, the chamber being either formed as a recess in the ladle floor or built up on the floor. Normally the horizontal area of the chamber is about one-third the area of the ladle floor.
