Problems solved by technology

This leads to the fact that in the event of a fault in the standstill state of the thin slab transport, the feeding of the furnace shuttle of the furnace ferry system cannot be carried out, since there is already an excessively long slab section in the roller hearth furnace

Embodiment Construction

[0018] The drawing shows a schematic side view of a production plant designed as a casting and rolling plant comprising a continuous thin slab casting plant or continuous thin slab caster 1 for producing cast strands 1a, a roller hearth furnace 2 and a rolling mill Column 3, the rolling mill train with associated auxiliary equipment. The devices of the continuous thin slab casting plant or continuous thin slab casting machine 1 are arranged successively in series and form a production line of the continuous thin slab casting plant or continuous thin slab casting machine.

[0019] In the thin slab continuous casting machine 1 upstream of the roller hearth furnace 2, the distribution container 4 is fed from the casting ladle 11, followed by the continuous casting mold 5, the supporting roll frame 6 with the bending unit 7 and straighteners. A first slab or strip separating device 10 is arranged upstream of the roller hearth furnace 2 on the feed side in the direction of slab tr...

Abstract

In the case of a production plant which comprises in series a thin-slab continuous casting plant (1), which is arranged upstream of a roller hearth furnace (2), the roller hearth furnace (2) and a rolling mill (3), which is arranged downstream of the roller hearth furnace (2) and has an assigned reeling plant (21), the continuous casting plant (1) and the rolling mill (3) can be operated in a continuous operating mode, the intention is to provide a solution that allows a slab buffer capacity to be provided for a continuously operated thin slab continuous casting plant when there is a fault causing a standstill in the transport of the slab or strip. This is achieved by the production plant having four slab or strip cutting devices (10, 14, 17, 24), which are arranged upstream and downstreamof the roller hearth furnace (2), in a section along the length of the roller hearth furnace (2) and on the outlet side of a first separate roll line (12) of the rolling mill (3).

Description

technical field [0001] The invention relates to a production plant comprising, in series, a thin slab continuous casting plant upstream of a roller hearth furnace, a roller hearth furnace containing a cast slab or at least one part-length of the cast slab separated therefrom, and rolling on a roller hearth A cast billet heated or held in a furnace or at least one part-length separate therefrom of a rolling mill train downstream of a roller hearth furnace with allocated coiling equipment. [0002] The invention also relates to a method for operating such a production plant. Background technique [0003] Known as a thin slab thin strip casting and rolling plant under the name CSP plant or CEM (Compact Endless Cast & Rolling Mill, Compact Endless Cast & Rolling Mill) is a production plant which in its production line A thin slab continuous casting plant, a roller hearth furnace and an adjoining rolling mill train with an assigned coiling plant are comprised in series. Such pl...
