Embodiment Construction

[0060] figure 1 A combined cast-rolling plant according to the invention for producing hot-rolled hot-rolled strip made of steel is schematically shown. Liquid steel with a hydrogen content figure 2 , at the top left is shown the bucket 8 ) suspended in the bucket rotation tower and poured there via the casting distributor 9 into the straight-through mold 2 configured as a funnel mold. A thin slab strip with a thin strip shell having a thickness of 55 mm and a width of 1700 mm is formed in the straight-through tool 2 . The partially solidified thin slab strip is continuously drawn from the straight-through die 2 and is supported, guided and passed through the nozzles of the secondary cooling device in the subsequent strip guide 4 (see Figure 4 , reference numeral 19) further cooling. The strap guide 4 has a vertical section 4a, an arcuate section 4b with a plurality of strap guide sections and a horizontal section 4c (see image 3 ). exist figure 2 Two strap guide segm...

Abstract

The invention relates to a method for endless production of a coiled hot strip (15) in a casting-rolling integrated plant. The problem to be solved is that of specifying a method by which high-qualityhot strip (15) of varying steel qualities can be cost-effectively produced. The method should also be reliable and cause extremely low operating costs. Said problem is solved by a method according toclaim 1.

Description

technical field [0001] The invention relates to the technical field of casting-rolling composite equipment. A combined cast-rolling plant is a plant in which a continuous casting plant for the continuous production of steel strip in a slab format, such as thin slab or medium slab, is connected directly and in one line with a Rolling machine connection. After the rolling mill, the hot strip is cooled in a cooling section and subsequently transported out, for example by coiling the strip into bundles (English coils: coils). These plants are also known in the literature, for example, from TSCR (Thin Slab Casting and Rolling) or Arvedi ESP plants. [0002] In particular, the invention relates to a continuously operating combined cast-rolling plant, wherein the casting plant is configured as a thin slab continuous casting plant (TSER, Thin Slab Endless Rolling: Thin Slab Continuous Rolling). Here, the continuous thin slab strip section (Dünnbrammenstrang) produced continuously i...
