Abstract
Abstract In continuous casting, the cast strand which emerges from the casting mold is conducted through a secondary cooling zone wherein it is guided and supported between latticed guide plates having guide faces which contact areas of the surface of the casting which are supported thereby, and having windows therethrough bounded by said guide faces. The unsupported areas of the surface of the casting which are exposed by said windows are cooled by sprays of cooling water from spray nozzles located in the windows.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
114 words
A method of cooling and guiding a continuous casting in the secondary cooling zone of a continuous casting machine, which comprises forming a continuous embryo casting in a chilled mold, guiding the casting between guide elements located downstream from said mold, said guide elements having latticed guide faces contacting areas of the surface of the casting which are supported thereby, and cooling the moving casting by spraying with cooling water only the unsupported areas of the surface of the casting that alternate in both the longitudinal and transverse directions with said supported surface areas for guiding the casting, removing the sprayed water to keep said supported surface areas being kept substantially free from water.
Claim 2
Independent Claim
114 words
A method of cooling and guiding a continuous casting in the secondary cooling zone of a continuous casting machine, which comprises forming a continuous embryo casting in a chilled mold, guiding the casting between guide elements located downstream from said mold, said guide elements having latticed guide faces contacting areas of the surface of the casting which are supported thereby, and cooling the moving casting by spraying with cooling water only the unsupported areas of the surface of the casting that alternate in both the longitudinal and transverse directions with said supported surface areas for guiding the casting, removing the sprayed water to keep said supported surface areas being kept substantially free from water.
Claim 3
Dependent Claim
43 words
A method according to claim 1, which is characterized in that any excess of sprayed water is drained off to the rear away from the casting to a point outside the spray cone which follows in the direction of movement of the casting.
Claim 4
Dependent Claim
43 words
A method according to claim 1, which is characterized in that an unsupported surface area of the casting is sprayed with cooling water supplied from two adjacent spray nozzles, the contiguous sprayed surface areas wetted thereby together substantially cover said unsupported surface area.
Claim 5
Dependent Claim
45 words
A method according to claim 1, which is characterized in that the guide faces above and on both sides of the nozzle are cooled by sprayed water and that a small region near the bottom guide face is not directly exposed to the sprayed water.
Claim 6
Dependent Claim
110 words
Apparatus for cooling and guiding a continuous casting in the secondary cooling zone located down-stream from the mold of a continuous casting machine, comprising a pair of opposed guide elements each comprising latticed guide plates with faces for contacting areas of the surface of the casting which are supported thereby, said guide plates having windows therethrough which are bounded by said guide faces, and spray nozzles located in said windows between said guide faces for spraying cooling water through said windows onto the un-supported areas only of the surface of the casting which are exposed thereby, said window areas being shaped to keep said contacting areas substantially free of water.
Claim 7
Dependent Claim
110 words
Apparatus for cooling and guiding a continuous casting in the secondary cooling zone located down-stream from the mold of a continuous casting machine, comprising a pair of opposed guide elements each comprising latticed guide plates with faces for contacting areas of the surface of the casting which are supported thereby, said guide plates having windows therethrough which are bounded by said guide faces, and spray nozzles located in said windows between said guide faces for spraying cooling water through said windows onto the un-supported areas only of the surface of the casting which are exposed thereby, said window areas being shaped to keep said contacting areas substantially free of water.
Claim 8
Dependent Claim
38 words
Apparatus according to claim 5, in which each of said guide plates contains at least two rows of windows which are consecutive in the direction of motion of the casting and which are separated by a guide face.
Claim 9
Dependent Claim
18 words
Apparatus according to claim 6, in which the windows in consecutive rows are staggered relative to each other.
Claim 10
Dependent Claim
26 words
Apparatus according to claim 5, in which the wetted area of the casting surface sprayed by the spray cone corresponds substantially to the unsupported casting surface.
Claim 11
Dependent Claim
25 words
Apparatus according to claim 5, in which the bottom wall of the window slopes downwards to the rear away from the casting at an angle.
Claim 12
Dependent Claim
17 words
Apparatus according to claim 9, in which the angle of slope is between 10* and 25* .
Claim 13
Dependent Claim
20 words
Apparatus according to claim 9, in which said bottom wall contains at least one hole for draining off accumulating water.
Claim 14
Dependent Claim
23 words
ApparatUs according to claim 9, in which the rear edge of the bottom wall extends beyond the spray nozzle away from the casting.
Claim 15
Dependent Claim
22 words
Apparatus according to claim 5, in which the latticelike guide faces are obliquely inclined to the direction of movement of the casting.
Claim 16
Dependent Claim
30 words
Apparatus according to claim 5, in which the latticelike guide plates are divided across the width of the casting into component plates and are replaceably attached to a supporting framework.
Claim 17
Dependent Claim
17 words
Apparatus according to claim 5, in which the latticelike guide plates consist of a wear-resistant cast iron.
Claim 18
Dependent Claim
21 words
Apparatus according to claim 5, in which the spacing between facing guide plates on opposite sides of the casting is adjustable.
