Patent Searching and Data


Title:
半固体合金の処理方法および装置
Document Type and Number:
Japanese Patent JP2006519106
Kind Code:
A
Abstract:
Apparatus for producing a semi-solid metal alloy from a molten charge includes vertically aligned treatment zones which are provided by vertically aligned passages defined by a plurality of spirally wound flow pipes which are interspersed between spirally wound induction coils. A container is mounted on a charging arrangement which displaces a first charge upwardly into the first treatment zone. Successive charges are introduced in a similar fashion thereby urging the previously introduced charge upwardly along the train of zones and until the leading charge is ejected from the top of the apparatus. The charge in each zone is subjected to controlled cooling and an induced electromagnetic field. The strength of the field and the rate of cooling are controlled to impede dendritic crystallisation and to promote globular primary crystal formation.
