Abstract
Abstract A mold for use in continuous casting of metals in which the backup plates are fastened to the liner by a novel means. The outside faces of the liner have a series of vertical ribs which define with the backup plates a plurality of water-circulation passages. Certain of the ribs have laterally directed lips under which metal strips are inserted. The strips carry studs which extend through the backup plates. Nuts are threadedly engaged with the studs and drawn up tightly. The water-circulation passages are unobstructed and all have the same hydraulic diameters, which are constant throughout the length of the passages. Hence water flowing through each passage has the same velocity.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
116 words
In a continuous-casting mold which includes an open-ended liner of heat conductive metal, and backup plates fastened to the outside faces of said liner, said liner having a series of vertical ribs in its outside faces defining with said backup plates a plurality of parallel unobstructed water-circulation passages, the combination therewith of improved means fastening said backup plates to said liner, said means comprising opposed laterally directed lips formed on certain of said ribs, metal strips inserted in these passages under said lips, the latter ribs defining with said strips additional unobstructed watercirculation passages, studs fixed to Said strips and extending through said backup plates, and nuts threadedly engaged with said studs outside said backup plates.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
57 words
A mold as defined in claim 1 in which said first-named passages are of equal width and equal depth, and said additional passages are wider and of less depth than the first-named passages, said passages all having equal hydraulic diameters, which are constant throughout the length of the passage whereby water flowing therethrough has the same velocity.
Claim 4
Dependent Claim
16 words
A mold as defined in claim 1 in which said strips are formed of abutting segments.
Claim 5
Dependent Claim
19 words
A mold as defined in claim 1 in which said strips are continuous through the length of a passage.
Claim 6
Dependent Claim
20 words
A mold as defined in claim 1 in which said strips are retained in said passages by frictional forces alone.
Claim 7
Dependent Claim
22 words
A mold as defined in claim 1 in which said strips carry knife edges which bite into the metal of said lips.
