Abstract

Abstract The mould cavity in a metal body forming part of a continuous casting mould is extended by way of a cavity in a second metal body arranged in line with the mould cavity, each body has separate means by which liquid coolant can be supplied to the outer surface of the body and the means associated with the second body permits the coolant supplied to the body to flow over the end of the body which is away from the first body.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 133 words
A continuous casting mould including a first metal body defining a mould cavity therethrough, means associated with the body by which liquid coolant can be supplied to the outer surface of the body, a second metal body in the form of a tube having a bore with substantially the same cross-sectional dimensions as those of the mould cavity, said bodies being arranged such that the longitudinal axis of the mould cavity and the tube are substantially horizontal and aligned so that the bore in the second body forms an axial extension of the mould cavity, and means associated with the second body by which liquid coolant can be supplied to the outer surface of the tube and allowed to flow over the end of the tube which is away from the first body.
Claim 2
Dependent Claim 133 words
A continuous casting mould including a first metal body defining a mould cavity therethrough, means associated with the body by which liquid coolant can be supplied to the outer surface of the body, a second metal body in the form of a tube having a bore with substantially the same cross-sectional dimensions as those of the mould cavity, said bodies being arranged such that the longitudinal axis of the mould cavity and the tube are substantially horizontal and aligned so that the bore in the second body forms an axial extension of the mould cavity, and means associated with the second body by which liquid coolant can be supplied to the outer surface of the tube and allowed to flow over the end of the tube which is away from the first body.
Claim 3
Dependent Claim 55 words
A continuous casting mould as claimed in claim 1 in which the means associated with the first body comprises a jacket arranged around the body at least over the major part of its length with a space between the body and the jacket and inlet and outlet ducts for liquid coolant leading to said space.
Claim 4
Dependent Claim 72 words
A continuous casting mould as claimed in claim 1 in which the means associated with the second body comprises a jacket arranged around the body at least over the major part of its length with a space between the body and the jacket, an inlet duct for liquid coolant leading to said space which space is open to atmosphere adjacent the end of the member which is away from the first member.
Claim 5
Dependent Claim 38 words
A continuous casting mould as claimed in claim 1 including a duct through which a gas or a liquid lubricant can be introduced into the bore in the second metal body at a position adjacent the first member.
Claim 6
Dependent Claim 145 words
A continuous casting mould including a first metal body defining a mould cavity therethrough, a metal tube having a bore therethrough with the same cross-sectional dimensions as the mould cavity, the body and the tube being arranged in end-to-end relation so that the bore of the tube is aligned with the mould cavity, a jacket positioned around the metal body over at least the major part of its length to define a space between the body and the jacket, inlet and outlet ducts for liquid coolant leading to said space, a jacket arranged around the tube at least over the major part of its length to define a space between the tube and the jacket, said space being open to atmosphere at the end of the tube which is away from the first body and an inlet duct for liquid coolant leading to said space.
Claim 7
Dependent Claim 145 words
A continuous casting mould including a first metal body defining a mould cavity therethrough, a metal tube having a bore therethrough with the same cross-sectional dimensions as the mould cavity, the body and the tube being arranged in end-to-end relation so that the bore of the tube is aligned with the mould cavity, a jacket positioned around the metal body over at least the major part of its length to define a space between the body and the jacket, inlet and outlet ducts for liquid coolant leading to said space, a jacket arranged around the tube at least over the major part of its length to define a space between the tube and the jacket, said space being open to atmosphere at the end of the tube which is away from the first body and an inlet duct for liquid coolant leading to said space.
