Definitions
- the invention relates to a plate with cooling channels, in particular a metal plate or a copper plate or a slab copper plate with cooling channels.
- Plates in particular slab copper plates or mold wall front plates, with cooling channels are known in the prior art.
- the applicant's prior application DE 10 2007 001 931 discloses a mold wall front plate which has a substantially smooth surface on the plate side facing the hot mold and has a groove structure of cooling channels on the cold side facing the plate side, always in each case two grooves formed as cooling channels are grouped together at their beginning and at their end.
- the cooling channels are substantially straight and aligned in parallel, with circular holes are provided around mounting holes or holes for receiving thermal sensors to direct a coolant in the cooling channel around the bore.
- the cooling channels are aligned straight and parallel to one another. In such plates, it has been found that the temperature distribution within horizontal sections of the plate can vary more widely, which can lead to thermal stresses in the plate or in a strand shell of a continuous casting.
- the object is achieved by a plate, such as in particular a metal or copper plate, with a hot side and a cold side, wherein grooves are introduced as cooling channels on the cold side, which substantially from an upper edge in an upper region to a lower edge in one run in the lower region, and are introduced into the plate rows of holes, wherein between rows of holes parallel grooves are provided, further the rows of holes are arranged adjacent grooves which have in the region of holes sub-grooves which a curved or curved or oblique have running course, wherein at least individual grooves or sub-grooves in the upper or in the lower region have a groove depth T1 and at least individual grooves or sub-grooves in the upper or in the lower region have a groove depth T2, where T1 is equal to or not equal to T2.
- a more homogeneous temperature distribution can be achieved.
- grooves or partial grooves are provided with a groove depth deviating from T1 in the lower or in the upper region.
- the groove depth T2 is reduced or enlarged relative to the groove depth T1.
- grooves or partial grooves with a groove depth differing from T1 are provided, which are adjacent to the bores.
- the grooves or partial grooves running parallel in the upper or in the lower region have a fluctuation width of their distance H of not more than +/- 20%, with the exception of the partial grooves adjacent to a bore in the horizontal direction.
- grooves are arranged in the region between two vertically arranged bores which have a groove depth which varies only by +/- 10% around the groove depth T1.
- all the grooves have substantially the same groove depth or the groove depth of the grooves in the lower region is lower than in the upper region.
- At least a second part of the grooves have a uniform distance H, which is greater than the distance of the upper grooves. It is also advantageous if the groove width N in the upper region is smaller than the groove width in the lower region. It is also advantageous if at least a first part of the grooves have a uniform spacing in the lower or in the upper region.
- an arcuate sub-groove is formed around a bore by three straight sub-grooves and four arc segment-shaped sub-grooves.
- the groove depth T1 in the range of 1 0 mm to 30mm and / or the groove depth T2 is in the range of 10 mm to 30mm and / or the distance H is in the range of 10 mm to 20mm and / or the transition - Radius R is in the range of 1 mm to 50 mm.
- FIG. 1 shows a view of a plate according to the invention.
- FIG. 1 shows a plate 1 according to the invention, in which grooves 2 designed as cooling channels are provided.
- the plate has an upper region 3 and a lower region 4.
- the plate 1 according to the invention has grooves 2, which are either completely rectilinear or have both straight and curved or curved or angled sub-grooves.
- the groove 6 is formed from almost the upper edge of the plate in the region 3 to almost to the lower edge of the plate in the region 4 in a straight line.
- Such rectilinear grooves 6 are arranged parallel to one another and preferably extend between rows of bores 5.
- five such straight grooves 6 are located next to each other in parallel between rows of bores 5. According to the concept of the invention, the number of these can be linear However, grooves 6 also vary, so that more or less than five such straight grooves 6 are provided side by side.
- grooves 7 which have rectilinear sub-grooves 8 and which have curved or curved or oblique sub-grooves 9 between rectilinear sub-grooves 9.
- the grooves 7 are preferably provided on both sides of a series of bores 5, wherein the curved part grooves 9 and part of the rectilinear part grooves 8 serve to guide the groove 7 around the bores 5.
- transitions with a radius R can be provided.
- the grooves in the upper region 3 of the plate 1 are distributed substantially more uniformly, apart from the sub-grooves that are immediately adjacent to the holes. According to the grooves in the upper region 3 of the plate 1 in the horizontal direction H are distributed or juxtaposed such that the center distance of the grooves with each other so varies, that a fluctuation range of highest +/- 20% occurs, except for the sub-grooves, which are immediately adjacent to the holes.
- At least individual grooves in the upper region are provided with a groove depth T1. Also, all grooves in the upper region can be provided with the groove depth T1. In contrast, individual groove regions in the upper region can be provided with a groove depth which deviates in the groove depth T1. Such groove areas may be part-grooves which are adjacent to the bores 5, such as the part-slot 10. The groove depth in this regard may be greater than the groove depth T1.
- the grooves in the lower region 4, which are adjacent to the holes 5, have no arcs around the holes 5 and they are substantially parallel over the entire length range. These grooves are advantageously formed in the lower region 4 with a groove depth T2 which is larger than the groove depth T1 and which is deeper than the groove depth T1. Also, the grooves or groove portions of the upper portion, which differ from the groove depth T1 may be formed with the groove depth T2.
- all the grooves can also have substantially the same groove depth.
- the groove depth of the grooves in the lower region may be lower than in the upper region.
- the groove width in the upper region may be smaller, larger than or equal to the groove width in the lower region, so that over the width of the grooves, an adaptation or homogenization of the temperature of the plate 1 can be achieved.
- transitions between straight sub-grooves and curved or curved or inclined sub-grooves with a transition radius R are rounded. It can be seen that an arcuate Partial groove can be formed around a bore by three straight sub-grooves and four arc segment-shaped sub-grooves.
- the straight part of the groove (8) may also be omitted, so that advantageously curved, curved and / or inclined part grooves adjoin one another.
- grooves (2, 6, 7) or part grooves (8, 9, 10) are provided with a groove depth differing from T1 in the lower or in the upper region, wherein the differing Nuttie- fe compared to Groove depth T1 can be increased or decreased by at least 10%.
