Abstract: The invention relates to a method for the manufacture of metal products, such as strip or lengths of rod or bar, from the molten metal to the final finished strip comprising a casting process (2) and a rolling process (4), wherein the casting process produces a long strand of solidified metal, which enters a temperature controlling furnace (3) and then sheared before it enters the rolling process (4), to produce a strand having a long strand finite length L which corresponds to the strand length required to produce at least one and preferably between (4) and (7) discrete desired final length of finished rolled product. Each strand enters the rolling process (4) and is threaded through the rolling stands (32) at a threading speed and which the speed is increased to a higher speed and the gauge of the strand is changed, by synchronously controlling the roll gaps and the speed of the rolling process, so that the gauge of the first discrete finished strip length is larger than the gauge of at least one subsequent finished strip length.

Abstract: The manufacture of thin hot-rolled steel strip comprises the steps of: (i) forming a liquid steel into a cast slab having a thickness of less than 100 mm in a continuous casting machine; (ii) rolling the slab in the austenitic region into an intermediate slab having a lesser thickness than the cast slab; and (iii) rolling the intermediate slab in the austenitic region into a strip. The slab or the intermediate slab is held for a period of time in a furnace in which a non-oxidizing atmosphere is maintained in contact with its surface. The thickness of the intermediate slab is in the range 5 to 25 mm and in step (iii) the intermediate slab is rolled to a final thickness of less than 1.2 mm. This enables production of particularly thin hot-rolled strip, using a simple plant.

Abstract: The invention relates to a combined regulating system for producing defined product characteristics in the rolling of austentic, mixed austentic and ferritic and ferritic steel qualities, using a measuring method to determine the roll gap of a roll pair by detecting the absolute position of the work and back-up rolls on the side facing away from the roll gap by optical position measurement. The upper edge of the top roll or the lower edge of the bottom roll is detected relative to the absolute position of the rolls, in segments over the barrel length, by means of adjacent sensors situated along the roll. The measuring results are incorporated in a suitable regulating operation that influences the geometry of the roll gap and rolled stock using a model that takes into account the influences of the deflecting and roll adjusting systems, the deflection of the rolls, flattening between the rolls, flattening between the work roll and the rolled stock and the wear and thermal crowning of the rolls. In addition to the necessary absolute thickness, the regulating operation ensures that the necessary thickness profile and the flatness criteria are produced.

Abstract: The invention relates to a method for rolling a metal strip (6), especially a steel strip, in a reverse rolling mill (1) with a coiler located upstream and a coiler located downstream (4, 5). The metal strip (6) is wound off of the upstream coiler (4) with a strip thickness (d) and at a strip temperature (T) above a set temperature (T*). It is then passed through the reverse rolling mill (1) with a first draught of at most 5 % and at a speed (v) before being wound up by the downstream coiler (5). The speed (v) at which the strip is passed through the rolling mill is selected with the aim of ensuring that the strip (6) has reached the set temperature (T*) by the time it is wound up. The strip (6) is then wound off of the downstream coiler (5), passed through the reverse rolling mill (1) with a second draught of at least 10 % and wound up by the upstream coiler (4).

After each pass, the rolled product is intensively cooled until completion of the ferrite conversion. The rolled product is then subjected to final rolling by passing several times through the ferrite zone, with a total strain of en>/=60 %, until a final thickness is obtained.
