Abstract
Abstract The leader for removing an ingot from a mold comprises a head including a readily deformable plate, which closes the bottom of the mold, and a refractory block affixed to the plate and projecting into the mold. The block is friable or readily deformable and has a transverse cross section which is smaller than the interior cross section of the mold.

Claim 1
Independent Claim
97 words
A leader to be fused to an ingot during casting in an ingot mold and for removal of the cast ingot through an open of the mold, comprising a head including: 1. a plate of readily deformable or breakable material, the plate being of the same configuration as the open mold end for closing the same before casting, and 2. a block of a friable or readily deformable refractory material affixed to the plate and projecting into the mold, a. the transverse cross section of the block being smalLer than the interior cross section of the mold.
