Abstract
Abstract A mould for use with a continuous casting machine comprises a body of thermally conductive material having an opening therethrough and the walls of the opening constitute the mould surface. The body is made up of a plurality of parts each of which provides part of the mould surface along the length of the opening and each part of the body has separate liquid cooling ducts or passages. The quantity of fluid passed for cooling purposes through the different parts of the body can be adjusted to give the required heat transfer conditions between the molten metal passed through the mould and the mould body.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
211 words
A mould suitable for use with a continuous casting machine comprising a body of copper having an opening therethrough the wall of which constitutes the mould surface, said body comprising two similar parts each of which is of rectangular form with one surface defining part of the mould surface along the length of the opening, means securing said parts together, each part of the body having a plurality of passages for receiving coolant spaced apart along the length of the opening with each passage extending through the part of the body in a direction transverse to the longitudinal axis of the opening, each passage comprising a pair of first bores extending from the surface opposite that defining said part of the opening, a pair of second bores extending one from each of the other opposite surfaces of the part of the body and interconnecting with said first bores and with the second bores of some of said passages being interconnected inside said body and thE first bores constituting the other passages extending into a recess in the surface of the part opposite that defining said opening, a removable cover for said recess, and first and second manifolds secured to said opposite surfaces to interconnect said second bores extending to said surfaces.
Claim 2
Dependent Claim
211 words
A mould suitable for use with a continuous casting machine comprising a body of copper having an opening therethrough the wall of which constitutes the mould surface, said body comprising two similar parts each of which is of rectangular form with one surface defining part of the mould surface along the length of the opening, means securing said parts together, each part of the body having a plurality of passages for receiving coolant spaced apart along the length of the opening with each passage extending through the part of the body in a direction transverse to the longitudinal axis of the opening, each passage comprising a pair of first bores extending from the surface opposite that defining said part of the opening, a pair of second bores extending one from each of the other opposite surfaces of the part of the body and interconnecting with said first bores and with the second bores of some of said passages being interconnected inside said body and thE first bores constituting the other passages extending into a recess in the surface of the part opposite that defining said opening, a removable cover for said recess, and first and second manifolds secured to said opposite surfaces to interconnect said second bores extending to said surfaces.
Claim 3
Dependent Claim
149 words
A mould suitable for use in a continuous casting machine, said mould comprising a body of thermally conductive material having two opposed ends and defining an opening extending from one of said ends to the other, with the surface of said body which surrounds the opening constituting the mould surface, said body comprising at least two parts, each extending from one of its ends to the other, and each defining part of said mould surface, each part of the body defining a plurality of passages extending substantially only in a transverse direction with respect to the opening and the passages being spaced apart along the dimension of said body extending between said ends, and each passage comprising a plurality of axially straight bores extending into part of the body from the outer surface thereof with the bores interconnecting to provide a continuous passage for the flow of cooling fluid.
Claim 4
Dependent Claim
149 words
A mould suitable for use in a continuous casting machine, said mould comprising a body of thermally conductive material having two opposed ends and defining an opening extending from one of said ends to the other, with the surface of said body which surrounds the opening constituting the mould surface, said body comprising at least two parts, each extending from one of its ends to the other, and each defining part of said mould surface, each part of the body defining a plurality of passages extending substantially only in a transverse direction with respect to the opening and the passages being spaced apart along the dimension of said body extending between said ends, and each passage comprising a plurality of axially straight bores extending into part of the body from the outer surface thereof with the bores interconnecting to provide a continuous passage for the flow of cooling fluid.
Claim 5
Dependent Claim
62 words
A mould as claimed in claim 2 in which the body comprises two similar parts, each defining half of the mould surface, with each of the halves of said mould surface being in the form of a channel in a flat face of its respective body part and means securing the two parts of the body with the flat faces in contact.
Claim 6
Dependent Claim
42 words
A mould as claimed in claim 3 in which the flat face of each part of the body is parallel to a flat outer face of its respective body part and normal to first and second sidewalls of its respective body part.
Claim 7
Dependent Claim
55 words
A mould as claimed in claim 4 in which each passage comprises a pair of interconnected first bores extending from the flat outer face of the part, a pair of second bores extending one from each of the sidewalls of the part with each second bore connecting with a first bore internally of the part.
Claim 8
Dependent Claim
55 words
A mould as claimed in claim 5 in which those passages positioned at the end of the mould to which molten metal is introduced to the mould have the first pair of bores extending into a recess in the flat outer face of the part of the body and a removable cover enclosing said recess.
