Problems solved by technology

[0009] b) The hydraulic line has to be routed from the valve base on the stationary workshop support at a distance to the roller section, whereby the maximum achievable power of the hydraulic actuating mechanism Limited due to very long tubing
In addition, the hydraulic system is prone to vibrations, whereby the accuracy of the position adjustment of the hydraulic cylinders is compromised

Embodiment Construction

[0051] figure 1 A continuous casting machine 1 for producing steel slabs S is shown in perspective. The liquid steel is delivered to the crystallizer 14 of the continuous casting machine 1 through the ladle turret 100 and the casting splitter. In the mold 14 a partially solidified slab S is formed, which is supported, guided and further cooled in the adjoining backup roll support 2 or slab guide. For this purpose, the strand guide 2 has a plurality of strand guide sections or roller sections 3 a to 3 l. The continuous casting machine 1 is located in a workshop, and the workshop is supported relative to the foundation by a workshop support with a plurality of I-shaped pillars 111 . The continuous casting machine 1 itself is supported on a technical support structure 11 . For example, the individual strand guide segments 3 a . Furthermore, on the casting platform, a dummy bar trolley 105 can be moved, which can transport dummy bars, not shown here, from the horizontal outlet...

Abstract

The invention relates to an open and / or closed-loop control device for a supporting-roller frame (2) in a continuous casting machine (1). The problem addressed by the invention consists in simplifying the cabling of said open and / or closed-loop control device, and in securing the transmitted signals as much as possible against influence from electromagnetic interferences. This problem is solved in that each hydraulic cylinder (7a...7d) comprises a position sensor (8a...8d) that has a bus interface (9a...9d); in that each roller segment (3, 3a...3l) is connected to a separate axis controller (10, 10a...10l) which comprises a bus interface (9e) and a network connection (12, 12a...12g), said bus interface (9e) of the axis controller (10, 10a...10l) forming a bus network (20) with said bus interfaces (9a...9d) of the position sensor (8a...8d); and in that the continuous casting machine (1) comprises a shared control system (13) with a network connection (12), said shared control system (13) and separate axis controller (10, 10a...10l) forming a star-shaped network (21).

Description

technical field [0001] The invention relates to a control and / or regulation device for a back-up roll stand of a continuous casting machine and a method for exchanging a roller section in a back-up roll stand of a continuous casting machine. [0002] In particular, the invention relates to a control and / or regulation device for a back-up roll stand of a continuous casting machine, wherein the back-up roll stand is composed of a plurality of roller segments following one another, the roll segments Accordingly, the lower frame and the opposite upper frame, which support the support rollers, can be adjusted relative to one another by means of at least one hydraulic cylinder when adjusted. [0003] Furthermore, the invention relates to a method for replacing a roll section in a back-up roll stand of a continuous casting machine, the method having the following method steps: [0004] - removing the roll section from the back-up roll bracket of the continuous caster; and [0005] ...
