Compact, flexible csp installation for continuous, semi-continuous and batch operation

Abstract

The invention relates to a compact, flexible CSP installation (1,101,201,301,401) for endless, semi-endless and batch operation with a casting machine, a roughing stand group (7,111,211) and a finishing stand group (12,118,218), wherein for the batch operation or the semi-endless operation, a coil store (8,113,213,501) is integrated into the roll table, which stores the pre-strip or slab coming from the roughing stand, with the coil store being deactivated in the case of endless operation. The coil store (8,113,213,501) is designed for an increased holding quantity of pre-strips or slabs such that two, three or more pre-strips or slabs can be wound to jumbo coils on a coil.

Description

TECHNICAL FIELD[0001]The invention relates to a compact, flexible CSP installation for endless, semi-endless and batch operation, as in particular in accordance with the introductory clause of claim 1.PRIOR ART[0002]In CSP installations (Continuous Strip Production), the strip is typically produced in a continuous process, as the name already suggests. This means that the casting process and the rolling process take place directly in succession from almost one heat.[0003]The DE 10 2006 054 932 A1 discloses a CSP installation in which both an induction furnace and a holding furnace are provided between the casting machine and the rolling train, in order to keep the thin slab to temperature or to increase the temperature slightly, in which both the holding furnace and also the induction furnace are activated, deactivated or respectively controlled or regulated depending on the type of operation.[0004]EP 0 286 862 A1 discloses an endless rolling, in which the casting and the rolling pr...

AI Technical Summary

Benefits of technology

[0008]It is an object of the present invention to provide an installation of the above-mentioned type, which allows a flexible change of type of operation and is nevertheless relatively short in construction.

[0011]It is also advantageous if a heating arrangement, such as an induction heating arrangement for example, is arranged between the roughing stand group and the finishing stand group.

[0013]Furthermore, it is advantageous if the coil store is designed to receive two, three or more coils. In this respect, the coil store has an increased holding capacity with a short length of the installation.

[0015]In addition, it is advantageous if in the case of a deactivated coil store, a roll table covering is used for better thermal insulation of the roll table. Thermal losses can thereby be minimized and the energy which is to be expended for tempering can be reduced.

Problems solved by technology

These installations have the disadvantage that they can either be operated in discontinuous operation or only in continuous operation.

With a changeover of rolls, in the case of a continuous operation it is no longer possible to maintain the operation.

In the case of a discontinuous operation, for many types of steel it is unfavourable to manufacture them in such a way, because losses in quality are connected therewith.

In addition, these installations are generally very long in their extent, which leads to a considerable cost factor in manufacture.
