Casting-rolling integrated plant and method for producing a hot strip with a final thickness < 1.2 mm on the casting-rolling integrated plant

A combined casting and rolling installation for producing hot-rolled strip with a final thickness<1.2 mm, preferably≤1.0 mm, comprising:

• at least a first continuous casting installation and a second continuous casting installation, wherein each continuous casting installation casts liquid steel into slabs;
• a slab manipulator for conveying the slabs from the continuous casting installations into a walking beam furnace,
• the walking beam furnace conveying the slabs from the slab manipulator into a rolling installation and heating the slabs to rolling temperature, wherein slabs from the first continuous casting installation and slabs from the second continuous casting installation pass completely through the walking beam furnace and are uniformly heated in the process;
• the rolling installation, comprising,
• a rough rolling mill for rough rolling the heated slabs to form a rough-rolled strip,
• a preferably thermally insulated coil box for winding up the rough-rolled strip to form a coil and for unwinding the rough-rolled strip,
• a joining device for connecting, without filler material, a foot of a leading rough-rolled strip to a head of a trailing rough-rolled strip to form an endless rough-rolled strip,
• a multi-stand finishing rolling mill for finish rolling the endless rough-rolled strip to form a finished strip with the final thickness,
• a cooling section for cooling the finished strip to form the hot-rolled strip, and
• a plurality of coiling devices for coiling the hot-rolled strip, wherein the roughing rolling mill, the coil box, the joining device, the multi-stand finishing rolling mill the cooling section and the coiling devices of the rolling installation are arranged in-line one behind the other, and the first continuous casting installation has a first offset in a first direction with respect to the rolling installation and the second continuous casting installation has a second offset in the first direction with respect to the rolling installation.
