Abstract
Abstract In a secondary cooling system for continuous casting plants longitudinally extending bars are used for contacting the ingot to cool same, to prevent bulges from occuring due to the ferrostatic pressure, and to guide the ingot along a predetermined path. These longitudinal bars are cooled with a coolant, and in the instant invention these bars have replaceable planks, which planks have the coolant passages in them and the working surface of the plank is contoured so as to have a different square area ingot contacting surface at any point along the longitudinal axis of the bar. The ingot contacting surface decreases in the direction of ingot travel which necessarily decreases the rate of cooling of the ingot.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
In a continuous casting plant having a plurality of bars in a secondary cooling zone, which bars extend substantially longitudinal to an ingot and are adapted to cool the ingot and guide same along an ingot path, the improvement consisting in that each bar has a plank detachably connected to it such that the plank is interposed between each said bar and said ingot path; passage means are provided in said planks for the circulation of a coolant introduced and removed respectively by inlet and outlet means; and that face of each plank which is adapted to contact the square area of ingot is contoured so as to have a different ingot contacting surface at any point along the longitudinal axis of the bar.
Claim 2
Dependent Claim
124 words
In a continuous casting plant having a plurality of bars in a secondary cooling zone, which bars extend substantially longitudinal to an ingot and are adapted to cool the ingot and guide same along an ingot path, the improvement consisting in that each bar has a plank detachably connected to it such that the plank is interposed between each said bar and said ingot path; passage means are provided in said planks for the circulation of a coolant introduced and removed respectively by inlet and outlet means; and that face of each plank which is adapted to contact the square area of ingot is contoured so as to have a different ingot contacting surface at any point along the longitudinal axis of the bar.
Claim 3
Dependent Claim
33 words
In a continuous casting plant as claimed in claim 1 wherein said square area of ingot contacting surface decreases in the direction of ingot travel which proportionately decreases the rate of ingot cooling.
Claim 4
Dependent Claim
45 words
In a continuous casting plant as claimed in claim 2 wherein said ingot contacting surface is in the form of a series of raised portions with recesses therebetween when viewed in cross-section, said raised portions continuously decreasing in width in the direction of ingot travel.
Claim 5
Dependent Claim
47 words
In a continuous casting plant as claimed in claim 2 wherein said ingot contacting surface is in the form of a plurality of distinct raised areas with recesses therebetween when viewed in plan, the number of said distinct raised areas decreasing in the direction of ingot travel.
Claim 6
Dependent Claim
49 words
In a continuous casting plant as claimed in claim 2 wherein said ingot contacting surface, in cross-section, is made up of a number of raised plateaus separated by recesses, the distance between the bottom of the recess to the top of the plateau being from 3 - 10 mm.
Claim 7
Dependent Claim
49 words
In a continuous casting plant as claimed in claim 1 wherein the plurality of bars on each side of said ingot path are divided into at least two independent groups and at least one of said groups being mounted so that it may be moved relative to the ingot.
Claim 8
Dependent Claim
67 words
In a continuous casting plant as claimed in claim 6 wherein there are two groups of bars on each side of said ingot path and each group is capable of movement relative to the ingot, while the first group is contacting and guiding the ingot, the second group is out of contact with the ingot and moving in a direction opposite to the direction of ingot travel.
