摘要:
A strand guide for a cast strand has a first roller bridge to one wide side of the cast strand and having ends defining two first section corners, a first fixed support adjacent the first roller bridge, a second roller bridge to the opposite wide side of the cast strand and having ends defining two second section corners, and a second fixed support adjacent the second roller bridge. Respective rows of rollers are rotatably mounted on each of the first and second roller bridges for engaging the respective wide sides and thereby supporting and guiding the cast strand. Respective first and second hydraulic positioners connect the first and second corners of the first and second roller bridges to the first and second fixed supports for individual positioning the rollers of the first and second roller bridges symmetrically or asymmetrically relative to the neutral phase of the cast strand.

The invention relates to a strand guide (1), in particular for a steel slab continuous casting installation having a number of segments (2) which support a strand (3) on two opposite sides (4, 5) with support elements (6, 7), wherein the support elements (6, 7) are arranged in a lower frame (8) and an upper frame (9), wherein the frames (8, 9) are formed to guide the strand (3) in a conveying direction (F). In order to be able to optimally adjust the strand support and to make it easier to change segment frames, the invention provides means (10) which can be used to adjust the upper and the lower frames (8, 9) relative to one another in the conveying direction (F).

Energy is recovered from steel products produced in a steel mill where the products are transported into a storage area by first extracting heat from the steel products prior to or after transport into the storage area by heat exchangers for a predetermined period in which residual heat of the steel products is transferred by the heat exchangers into a heat-transfer medium to heat same. The heated transfer medium is then transferred via heat-transfer transport lines for power generation or for direct use of the process heat in other heat consumers. This transport of the heat-transfer medium from the heat exchangers to the power-generating plant in the heat-transfer transport lines is carried out only at pump feed pressure or using as a heat-transfer medium liquid mineral or synthetic thermal oil or a salt melt so as not to build up a steam pressure above 2 bar.

The invention relates to a strand guide roller 100 of a strand guide device for guiding a cast strand 200. The stand guide roller includes at least one first and one second sectional roller arranged next to each other, wherein the first sectional roller 110-1 has a roller journal 112-1 at its end surface adjacent to the second sectional roller. In addition, the strand guide roller includes a middle bearing 120-1, 120-2 between both sectional rollers 110-1, 110-2 for receiving and supporting the roller journal 112-1 of the first sectional roller. In order to improve strand guidance by increasing the bearing surface for the strand 200, it is suggested, according to the invention, that the first and second sectional rollers be connected with each other outside of the middle bearing by a plug-in connection. Then, according to the invention, the middle bearing is formed simply as unsplit separate bearing with an essentially smaller window width in comparison with a split bearing.

The invention relates to an apparatus (100) for carrying cooling water away from the narrow sides (210) of a slab (200) passed essentially vertically through a secondary cooling device after casting in a continuous casting installation. In order to prevent partial overcooling of the slab at its edges, the apparatus (100) according to the invention comprises a plurality of water drainage devices (110-n), which are arranged such that they are distributed in a vertical direction over the length of the narrow side of the slab. This plurality of water drainage devices (110-n) is carried by a vertically arranged collecting downpipe (120). The collecting downpipe additionally serves for collecting the cooling water that is drained by the plurality of water drainage devices (110-n) and carrying it away in a decentralized manner.

The invention relates to a device for supporting and oscillating a continuous casting mold (1) for continuously casting molten metals, particularly molten metal materials, comprising: guide elements (4) symmetrically arranged on both sides of the central longitudinal axis (2) of the casting; fixed supporting parts (5), and; a continuous casting mold (1) supported on paired oscillating devices (6). The inventive device facilitates the accessibility to individual modules for maintaining and/or eliminating damages. To this end, a module (7) that, itself, can be removed, is formed from paired bearing blocks (9) with guide elements (4) and with a supporting casing (7a) connected to said bearing blocks. The module is placed upon a stationary submodule (7b) and detachably connected thereto.

A device for the support and oscillation of a continuous casting mould (1) for casting liquid metal, particularly liquid steel, comprising guide elements (4) which are mounted on fixed carrier components (5) and which is actually by means of oscillation devices (6). In order to shorten time required for mounting and dismounting and therefor to lower the down times and costs of said continuous casting device, a first module (7) is made of guide elements (4) and carrier components (5) and a second module (8) consists of the oscillation device (6). The second module (8) can be dismantled via an outlet (9) which extends laterally, perpendicular to the plane of symmetry (2) below the guide elements (4) or in between guide elements (4). Each of the two modules (7,8) can be dismounted or re-mounted in a manner which is temporally and locally independent from the other respective module (7,8).
