A heat transfer conduit for extracting heat from a molten metal in transit from a containing vessel or delivery system includes at least two elongate segments separable along separation lines which lie generally in the direction of a longitudinal center line of the conduit, which in use, define a unitary structure. The segments can be disassembled following use for the removal of solidified material and other matter from the conduit interior.

Method and apparatus for cooling a flow of molten material

A method of removing heat from molten metal in which the metal is caused to flow freely within a gaseous media or vacuum over a body disposed within the metal stream such that any tendency for the metal to solidify during its passage is effective on the surface of said body against which the solidifying metal contracts into intimate contact therewith. The body may be forcibly cooled, e.g. by water. Accordingly, since the liquid metal is not enveloped by a channel or pipe, the solidifying shell tends to shrink on to the body, no gap is created, and this much higher heat transfer coefficients between the shell, the liquid metal, and the cooling body are achieved.

Liquid metal processing

The invention provides an arrangement for producing solid metal with fine solidification structure from liquid metal including the steps of transferring liquid metal with a minimum flow through a hollow carrier; the minimum bulk velocity of the metal through the carrier being 50 cm/sec.
