TITLE: Method of cooling a cast strand during continuous casting.
European Patent Application EP0080433 A1

ABSTRACT:
Abstract not available for EP0080433
Abstract of corresponding document: US4473106
A continuously cast strand or ingot of metal is cooled as it emerges
from the mold by applying a coolant directly to the surface of the
strand. In order to prevent distortion at the foot of the ingot due to
too abrupt cooling, polymers of molecular weight 104-108 are added to
the coolant at least during the initial phase of casting. By the
addition of polymers to the coolant the kinetics of formation and
discharge of vapor bubbles as the coolant strikes the ingot surface are
significantly altered due to the reduction in the surface tension of
the coolant; as a result of this an insulating film of coolant vapor
forms on the surface of the ingot thus reducing the heat flow from the
ingot.
