Production plant operable in continuous operation and method for operating the production plant in fault situations

Abstract

For the thin slab continuous casting plant (1) comprising in series upstream of the roller hearth furnace (2), the roller hearth furnace (2) and the coiling plant (21) downstream of the roller hearth furnace (2) and with distribution The production equipment of the rolling mill train (3), wherein the continuous casting equipment (1) and the rolling mill train (3) can be operated in continuous operation mode, should provide such a solution, which can realize the operation in continuous operation In thin slab continuous casting plants, a slab buffer is provided in the event of a fault causing a standstill of the slab or strip transport. This is achieved in that the production plant has four slab or strip separating devices (10, 14, 17, 24), which are arranged before and after the roller hearth furnace (2), in a length zone of the roller hearth furnace (2) In the section and on the exit side of the first stand group (12) of the rolling mill train (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...

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
