摘要： A steel strand having a thickness of 40 to 50 mm in cast in an oscillating mold for continuous casting at a speed of 2 to 20 m/min. The not yet completely solidified steel strand emerging from the mold is squeezed to such an extent that the inner walls of the already solidified strand shell are welded to one another. After the steel strand reduced in thickness in this way has been cooled to 1000.degree. to 1200.degree. C., the strip is rolled out in at least one pass with a 5 to 85% degree of deformation.

摘要： The continuous casting installation includes:a) a funnel-shaped oscillating mold having cooled walls to produce a steel strip having a thickness of 40 to 50 mm; andb) a deforming device disposed at a distance of at most 0.5 m from the mold outlet to squeeze the steel strip to a thickness of not more than 25 mm.

摘要： A process for continuous casting of a metal comprises continuously withdrawing a strand of the metal from a mold along a strand withdrawal direction, measuring the expansion of an inside wall of the mold along the strand withdrawal direction to obtain a component of inside wall expansion in the strand withdrawal direction due to mechanical forces exerted on the inside wall, and controlling the speed of withdrawal based on the component of inside wall expansion in the strand withdrawal direction due to mechanical forces. If the component of inside wall expansion of in the strand withdrawal direction due to mechanical forces exceeds certain limit values, the withdrawal step is slowed or interrupted, thereby eliminating break-outs due to cobbles. In an embodiment of the invention, expansion measurements are also taken along a direction transverse to the withdrawal direction, enabling the elimination of the component of expansion in the withdrawal direction due to heat.
摘要翻译：一种连续铸造金属的方法包括：沿钢丝绳退出方向从模具连续取出金属股，测量模具内壁沿钢丝绳退出方向的膨胀，从而获得内壁膨胀成分由于施加在内壁上的机械力引起的股线退出方向，并且由于机械力而基于股线退出方向上的内壁膨胀部分来控制退出速度。如果由于机械力引起的股线退出方向的内壁膨胀部分超过某一极限值，则退出步骤变慢或中断，从而消除由于鹅卵石而导致的断裂。在本发明的一个实施例中，也沿横向于抽出方向的方向进行膨胀测量，从而能够消除由于热量引起的抽出方向的膨胀分量。

摘要： A method for producing a steel strip which has been cast as a stand in a cooled oscillating continuous chill mould, comprises squeezing the strand emerging from the chill mould until it has a first cross-sectional thickness (40-50 mm), followed by hot rolling the strand until it has a second cross-sectional thickness (2-25 mm). Deviations in the normal path of travel of the strand following hot rolling are corrected by adjusting the thickness to which the strand is subjected during the first squeezing step.

摘要： The invention is directed to a hot-rolling process and a hot-rolling mill for metal strips (5) having one or more roll stands with work rolls (1, 2). In order to prevent surface defects on the work rolls (1, 2), a coolant liquid is sprayed on the entry side in a narrow region extending immediately in front of the roll gap exclusively by a series of flat jet nozzles in such a way that their core jets primarily strike the surface of the work rolls or are directed into the roll gap for direct cooling and in that the entering metal strip is acted upon at the same time by the same coolant liquid for protecting the surfaces of the rolls from the radiated heat of the metal strip. The spraying of the coolant liquid is regulated in such a way that the metal strip is cooled only in a very narrow outer zone. In so doing, the temperature at the surface of the work rolls (1, 2) is adjusted in such a way that it lies below the boiling point of the coolant liquid at least immediately in front of the roll gap.
