Definitions
- Mold unit for the continuous casting of metal products as well as continuous casting plant
- the invention relates to a mold unit for the continuous casting of metal products, in particular for the continuous casting of blocks before. Furthermore, the invention relates to a continuous casting plant.
- Plattenkokil len comprise several separate, contacting Kokil lenplatten, which together form a mold with a polygonal len, in particular rectangular cross-sectional shape.
- tube molds comprise a mold tube, which forms a casting mold with a round, in particular circular cross-sectional shape or a polygonal, in particular rectangular cross-sectional shape.
- a plate mold has mold plates can be stored in such a way that a distance between opposing mold plates can be adjusted so that metal products of different formats can be cast with the plate mold.
- Another advantage of a plate mold is that damaged or worn mold plates can be specifically reworked or replaced.
- a disadvantage of a plate mold is that there may be gaps between adjacent mold plates in the corner areas thereof, into which foreign bodies, such as residues of (liquefied) casting powder, can penetrate and / or liquid metal can penetrate. This can result in sharp-edged burrs, so-called fins, on the strand. When a strand is conveyed out of a plate mold, fins are subject to a higher adhesive friction than the remaining surface of the rod. As a result are mechanical tensions that can tear a forming strand shell.
- tube molds have been used mainly for the continuous casting of small-format metal products.
- plate molds have conventionally been used for the continuous casting of large-format metal products.
- tube molds are now increasingly being used in the continuous casting of large-format metal products, since the problem of the formation of fins usually does not occur with a tube mold.
- EP 1 468 760 A1 discloses a mold unit for the continuous casting of metal products, which comprises a mold tube which has a plurality of corner regions.
- the mold unit comprises a plurality of separate reinforcement plates which are fastened to the outside of the mold tube and together surround the mold tube, a coolant guide gap for guiding a coolant being formed between each of the reinforcement plates and the mold tube.
- An object of the invention is to enable a mold unit which has a mold tube with a polygonal outer cross-sectional shape, or a continuous casting installation equipped with such a mold unit, to have a long service life.
- the mold unit according to the invention for the continuous casting of metal products in particular for the continuous casting of ingots, comprises a mold tube with a polygonal outer cross-sectional shape, which has a plurality of corner regions, and a plurality of separate reinforcing plates which are fastened to the outside of the mold tube and together enclose the mold tube, wherein a coolant guide gap for guiding a coolant is formed between each of the reinforcing plates and the Kokil lenrohr.
- the reinforcing plates at the corner of the mold tube are not connected to one another by screw connections.
- the reinforcing plates are not screwed together at the corner regions of the mold tube. Specifically, there is no direct contact between the reinforcement plates. Any sealing element or several sealing elements between two adjacent reinforcing plates do not hinder the thermal expansion of the reinforcing plates or only insignificantly, since the sealing element is elastically deformable and its rigidity is very low. Compared to the rigidity of the reinforcement plates, the rigidity of the sealing elements is negligible.
- the invention is based on the finding that there is a thermal expansion of the die tube and the reinforcing plates during operation of the die unit.
- the reinforcement plates are screwed together at the corner regions of the mold tube, as is provided, for example, in EP 1 468 760 A1, the reinforcement plates at the corner regions of the mold tube are prevented from thermal expansion. As a result, mechanical stresses can occur, particularly at the corner areas of the mold tube, which can damage the reinforcement plates and / or the mold tube and consequently lead to a shorter service life of the mold unit.
- the reinforcement plates are not screwed to each other at the corner areas of the mold tube, the reinforcement plates can carry out greater thermal movements relative to one another at the corner regions of the mold tube. As a result, the occurrence of large mechanical stresses can be avoided, particularly at the corner regions of the coil tube become. In this way, a longer life of the mold unit and consequently also a longer life of a continuous casting system equipped with such a mold unit can be achieved.
- the reinforcement plates at the Eckbe range of the mold tube are not integrally connected to each other, so that the reinforcement plates also not through a cohesive connection can be prevented from thermal expansion.
- polygonal is not necessarily to be understood in the strictly mathematical or geometric sense.
- a “polygonal” (cross-sectional) shape such as a rectangular (cross-sectional) shape, in particular a ( Cross-sectional shape with rounded corners.
- the mold tube of the mold unit is a casting mold before lying, which has a plurality of side walls which are integrally formed with one another.

- the aforementioned coolant guide gaps are each laterally limited by one of the reinforcing plates and one of the side walls of the mold tube.
- the mold tube and the reinforcement plates are spaced apart at all points.
- the mold tube and the reinforcing plates are advantageously not in contact with one another, but rather are arranged in contactless fashion at all points. This can prevent heat from being conducted directly from the mold tube to the reinforcement plates.
- heat can be emitted to the coolant in this way over a comparatively large area of the reinforcing plates and over a comparatively large area of the mold tube, as a result of which a particularly strong cooling effect can be achieved using the coolant.

- the mold cavity of the mold tube can be bent out. That is, the mold unit can be a so-called arc mold. Alternatively, the mold cavity can be straight.
- the mold tube has a wall thickness of at most 35 mm, preferably at most 30 mm. On the one hand, this enables a cheaper production of the mold tube, since comparatively little material is required to produce the mold tube.

- the wall thickness of the mold tube can be constant over the entire mold tube.
- the mold Pipe have different wall thicknesses.
- the wording that the mold tube has a wall thickness of at most 35 mm or at most 30 mm can be understood such that the mold tube at its / its thickest point (s) has a wall thickness of at most 35 mm or . has a maximum of 30 mm.

- the connecting elements are advantageously designed as expansion bolts.
- An advantage of connecting elements designed as expansion bolts is that they permit thermal movement of the reinforcing plates relative to the mold tube, without causing excessive tension in the connecting elements, which could possibly lead to a plastic and / or separating deformation of the connecting elements.
- the respective connecting element preferably has a threadless shaft section. Whose diameter can in particular be smaller than the diameter of the threaded section or the threaded sections of the respective connecting element. Alternatively, the diameter of the shaft section of the respective connecting element can be the same or approximately the same size as the diameter of the threaded section or the threaded sections.

- the mold unit can have a plurality of
- the clamping sleeves are preferably each clamped between one of the reinforcing plates and the mold tube.
- the clamping sleeves can rest on the end face of the threaded inserts or a clamping sleeve with a threaded insert can form a single component. If a threaded insert protrudes from a recess in the mold tube, it can be achieved in this case that the clamping sleeve transmits a force to the threaded insert, but not directly to the side wall of the mold tube.
