Abstract: Method for the manufacture of a steel strip, whereby molten steel is cast in a continuous casting machine into a slab and, while making use of the casting heat, is conveyed through a furnace apparatus, is roughed in a roughing apparatus, and finish-rolled in a finishing apparatus into a steel strip of a desired finished thickness, whereby in an endless or semi-endless process a. for the manufacture of a ferritically rolled steel strip, the slab is rolled in the roughing apparatus in the austenitic range and after the rolling in the austenitic range is cooled to a temperature whereby the steel has essentially a ferritic structure, and the strip, the slab or a part of the slab is rolled in the finishing apparatus at speeds essentially corresponding to the entry speed into the finishing apparatus and the subsequent thickness reductions and in at least one stand of the finishing apparatus is rolled in the ferritic range; b. for the manufacture of an austenitically rolled steel strip, the strip leaving the roughing apparatus is heated to or held at a temperature in the austenitic range and is rolled in the finishing apparatus essentially in the austenitic range to the finished thickness and, following that rolling, is cooled down to a temperature in the ferritic range; and the ferritically or austenitically rolled strip after reaching the desired finished thickness is cut to portions of the desired length which are subsequently coiled.

Abstract: A hot rolling installation should be constructed and able to be operated so that strips of materials, which can be shaped with different levels of difficulty and have a thickness of less than 1 mm, can be rolled. According to the invention, strip speeds of 15 m/sec should not be exceeded at the outlet of the last roll stand regardless of the material being used, and the hot-rolled strip should have austenitic structures. To this end, the invention provides that thin slab thicknesses of approximately 50 mm are used for easily shapeable material, that the first of seven stands is driven or executes only a smoothing pass, the slab is de-scaled in front of and behind the first stand, and that the second to seventh stand effects the reduction in thickness to less than 1 mm.

Abstract: A plain carbon steel strip (12) is continuously cast in a twin roll caster (11) and passes to a run out table 17 on which it is subjected to accelerated cooling by means of cooling headers (18) whereby it is cooled to transform the strip from austenite to ferrite at a temperature range between 850 DEG C and 400 DEG C at a cooling rate of not less than 90 DEG C/sec, such that the strip has a yield strength of greater than 450MPa. The strip after casting and before cooling is passed through a hot rolling mill to reduce the thickness of strip by at least 15% and up to 50%.

Abstract: A process to obtain in continuous casting and in the immediately subsequent in-line rolling stage a pre-strip with characteristics such as to make it possible, in the subsequent processes downstream, to manufacture plates and coils in high strength steels with gauges as low as 0.6 mm, with a low or very low percentage carbon content, these coils having, for certain applications, the characteristics of a cold rolled product, in which the thickness of the thin slab leaving the mould is first reduced with a liquid core (soft reduction) and then rolled in-line with a solid core. Particular ranges of value are indicated which characterise the thickness, speed and temperature parameters of the pre-strip leaving the casting machine and entering the rolling stage, as well as cooling characteristics. Some characteristics of the cooling plant which allow the above-mentioned process to be performed are also defined.

Abstract: A method of controlling a continuous steel strip casting process based on customer-specified requirements includes a general purpose computer in which product specifications of steel product ordered by a customer is entered. The computer is configured to automatically map the product specifications to process parameters/set points for controlling the continuous steel strip casting process in a manner to produce the customer ordered product, and in one embodiment produces a process change report detailing such process parameters/set points for operator use in physically implementing such process parameters/set points in the strip casting process. Alternatively, the computer may provide the process parameters/set points directly to the strip casting process for automatic control thereof in producing the customer ordered steel product. The process of the present invention is capable of substantially reducing the time between a customer request for a steel product and delivery thereof over that of conventional steel manufacturing processes.
