    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.

    Abstract: A plain carbon steel strip is continuously cast in a twin roll caster and passes to a run out table on which it is subjected to accelerated cooling by means of cooling headers whereby it is cooled to transform the strip from austenite to ferrite at a temperature range between 850° C. and 400° C. at a cooling rate of not less than 90° C./sec, such that the strip has a yield strength of greater than 450 MPa. 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: Method for the manufacture of a steel strip, wherein molten steel is cast into a slab, conveyed through a furnace, roughed in a roughing apparatus and finish-rolled in a finishing apparatus. The method comprises an endless or semi-endless process having either step a or step b, wherein a and b respectively comprise (a) manufacturing a ferritically rolled steel strip, wherein the slab is rolled in the roughing apparatus in the austenitic range and then cooled to a ferritic structure, and wherein the strip is rolled in the finishing apparatus at speeds essentially corresponding to the entry speed into the finishing apparatus, and (b) manufacturing an austenitically rolled steel strip, wherein the strip leaving the roughing apparatus is heated to the austenitic range and is rolled in the finishing apparatus and then cooled down to the ferritic range. In both step a and b, there is no material connection between the steel in the continuous casting machine and the steel being rolled in the finishing apparatus, and the strip is fed from the roughing apparatus to the finishing apparatus without intermediate storage. Additional steps include cutting the ferritically or austenitically rolled strip, after reaching the desired finished thickness, to portions of the desired length, and coiling the cut portions.
