Embodiment Construction

[0028] exist Figure 1a The embodiment of a continuous casting plant for metal strip, especially steel strip, shown in generally comprises two casting rolls 1, 1' which are internally cooled and run in opposite directions about their axes in a horizontal position Rotary drive. The housing walls 2, 2' fitted between the flat end sides 3, 3' of the rollers 1, 1' together with the side walls of the rollers 1, 1' delimit a casting space, which is connected, for example, to the tundish via refractory ducts ( not shown) molten steel is continuously cast into the space. In this way, the strip 6 solidifies and is removed in the direction indicated by the arrow 5, and its thickness is generally 1 to 10 mm.

[0029] In the embodiment shown, the strip 6 passes in a known manner through an induction heating furnace 7; this induction heating furnace is used to reheat the strip before it enters a hot rolling stand which will The thickness of the strip 6 is reduced by, for example, 10% or ...

Abstract

Process for trimming the edges (9, 9') of a thin metal strip (6), cast directly from molten steel (4), involves controlled cooling of the edges before trimming to make the edge zones more brittle than the remaining strip metal. Edge cooling starts at 950-1100 deg C, and edge trimming cutters (15,15') act directly after the cooling stage and before the strip is wound into a roll. Preferred Features: Edge cooling action is performed after hot rolling, where the strip has been heated by an induction heating system, or directly in-line after casting. Edge cooling action is applied by bars (10, 10') with spray jets which direct streams of a coolant fluid at the strip edges.

Description

technical field [0001] This invention relates to the continuous casting of metals, and more particularly to the direct casting of thin strips from liquid metal. Background technique [0002] Continuous casting of metal strips having a thickness of a few millimeters, preferably less than 10 mm, especially strips made of carbon steel or stainless steel, is currently known in the art. [0003] Continuous casting of metal strip is usually performed on equipment known as a twin roll caster. This apparatus, the main part of which forms the permanent mold and in which the strip is cured, comprises two rollers whose substantially horizontal axes are arranged opposite each other and driven in rotation about their axes in opposite directions. These rollers are cooled intensively on the inside and their sides form a mold with movable walls where the strip begins to solidify in the form of strip shells; these strip shells develop further from the roll surface. These strip shells conve...
