Abstract
Abstract A water inlet construction for continuous-casting molds to distribute cooling water more uniformly across the mold face, and a method of introducing water. The mold has a plurality of parallel vertically extending water circulation channels between its outer wall and liner. A single inlet serves several channels at each side, which is conventional. Invention is to interpose a baffle having sloping edges between the inlet and channels. The baffle directs water to the remote channels which otherwise do not receive proportional shares.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
In a continuous-casting mold which includes a tubular liner and outer walls fixed to said liner, a face of which mold has a plurality of parallel vertically extending water-circulation channels between said wall and said liner, an inlet to said channels located near the bottom of the mold, and a chamber affording communication between said inlet and channels, said inlet serving a number of channels, some of which are approximately in line with the inlet and others of which are more remote therefrom at each side, the combination therewith of a construction for distributing water more uniformly among said channels, said construction comprising a baffle interposed between said liner and said wall across the top of said chamber, said baffle having lower edges which slope upwardly in each direction from an apex located approximately in line with the center line of said inlet.
Claim 2
Dependent Claim
143 words
In a continuous-casting mold which includes a tubular liner and outer walls fixed to said liner, a face of which mold has a plurality of parallel vertically extending water-circulation channels between said wall and said liner, an inlet to said channels located near the bottom of the mold, and a chamber affording communication between said inlet and channels, said inlet serving a number of channels, some of which are approximately in line with the inlet and others of which are more remote therefrom at each side, the combination therewith of a construction for distributing water more uniformly among said channels, said construction comprising a baffle interposed between said liner and said wall across the top of said chamber, said baffle having lower edges which slope upwardly in each direction from an apex located approximately in line with the center line of said inlet.
Claim 3
Dependent Claim
24 words
A construction as defined in claim 1 in which said lower edges slope at an angle of about 5* to 15* to the horizontal.
Claim 4
Dependent Claim
39 words
A construction as defined in claim 1 in which said mold is square in cross section and which is duplicated at each face of the mold, said inlets being located approximately on the vertical center lines of the faces.
Claim 5
Independent Claim
91 words
A method of introducing water to a plurality of parallel vertically extending channels in a continuous-casting mold from an inlet aligned with a channel near the center of the plurality, said method comprising introducing the water from the inlet first to a chamber which communicates with the lower ends of said passages, and distributing the water from said chamber through a relatively restricted area to the channels nearer the center and an increasing area to channels more remote from the center, whereby the water is distributed substantially uniformly among the channels.
Claim 6
Independent Claim
91 words
A method of introducing water to a plurality of parallel vertically extending channels in a continuous-casting mold from an inlet aligned with a channel near the center of the plurality, said method comprising introducing the water from the inlet first to a chamber which communicates with the lower ends of said passages, and distributing the water from said chamber through a relatively restricted area to the channels nearer the center and an increasing area to channels more remote from the center, whereby the water is distributed substantially uniformly among the channels.
