CONTINUOUSLY OPERABLE PRODUCTION PLANT AND METHOD FOR OPERATING THE PRODUCTION PLANT WHEN THERE IS A FAULT
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), wherein 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 downstream of 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).
Apparatus and method for the production of strip
An apparatus for the hot production of strip (N) including a casting machine (11) configured to cast a thin slab (TS), a heating device (16) configured to maintain the temperature of and/or heat said thin slab (TS), at least one roughing unit (19) and a finishing unit (20) configured to obtain a strip (N), and wherein said casting machine (11), the heating device (16), the roughing unit (19), and the finishing unit (20) are disposed aligned along a common working axis (Z).
METHOD AND PLANT FOR PRODUCING FLAT ROLLED PRODUCTS
The invention concerns a method and a plant for obtaining strips (S), wherein the plant has at least three casting lines (11, 12, 13) disposed in parallel, of which two are lateral (11, 13) and one is central (12), and at least two rolling lines (14, 15) aligned with two of said at least three lateral casting lines (11, 12 13).
Steel plant for the production of long metal products and corresponding production method
A steel plant for the production of long metal products comprises a continuous casting machine, a rolling mill disposed downstream of the continuous casting machine, and one or more transfer paths for the semifinished cast products, configured to connect the continuous casting machine and the rolling mill. The steel plant also comprises at least one maintenance and/or heating furnace, a discharge plate for the semifinished cast products, and an aerial transfer device.
Apparatus and method for production of long metal products
An apparatus (100) and method for the production of elongated metal products such as bars, rods or the like: A rolling mill (10) with at least one rolling stand (5); a casting station (20) with at least a first casting line (2a) and at least a second casting line (2b), each line (2a, 2b) being operable to produce respective elongated intermediate products (b2a, b2b), such as billets; wherein at least the first casting line (2a) is directly aligned with the rolling mill (10), the first casting line (2a) being configured to feed the rolling mill (10) with a fully continuous casting strand or with cast elongated intermediate products; and the second casting line (2b) is not aligned with the rolling mill (10). A bidirectional transfer device (30) for transferring elongated intermediate products (b2b) of the second casting line (2b) alternatively in a first direction from the second casting line (2b) to the first casting line (2a) to align the elongated intermediate product (b2b) with the rolling mill (10) or in a second direction from the at least second casting line (2b) to a cooling bed (40).

Tandem rolling mill output method and installation with coiling carousel coupled with on-line inspection
Method for coiling and on-line inspection of a continuously-rolled metal strip, involving continuous coiling on at least one mandrel of a coiling station, preferably of carousel type, wherein: the strip is cut by a shears situated before the coiling station, advances over a certain length on an insertion table so as to at least partially cover this table and is then cut a second time by the shears in order to obtain a specimen; the coiling performed on the mandrel is terminated and the coil is discharged from the coiling station; at the same time, the insertion table bearing the specimen is moved parallel to the rolling-coiling line until it lies in an inspection line comprising an inspection table; the specimen is inspected on the inspection table so that faults can be detected; once the specimen has left the insertion table, the latter is placed back in the rolling-coiling line.
PLANT AND METHOD FOR THE PRODUCTION OF METAL
Plant for the production of metal products comprising: a main rolling line configured to roll thin slabs; a main casting line of thin slabs associated downstream to a heating and/or maintenance furnace to heat and/or maintain the cast thin slabs at a uniform temperature, the main casting line being positioned upstream of and aligned with said main rolling line, the main rolling line being configured to roll the thin slabs arriving at least from the heating and/or maintenance furnace; an auxiliary rolling line provided with at least one rolling unit configured to roll conventional slabs and obtain thin slabs, and with a transfer unit positioned downstream of the rolling unit and configured to transfer the thin slabs rolled by the latter to the heating and/or maintenance furnace.
