Disclosed is a method of producing a copper alloy sheet material, wherein the copper alloy sheet material contains nickel (Ni) 0.5 to 1.5% by weight; cobalt (Co) 0.3 to 1.5% by weight; silicon (Si) 0.35 to 0.8% by weight; chromium (Cr) 0.05 to 0.5% by weight; a balance amount of copper (Cu); and inevitable impurities. Further, disclosed is a copper alloy sheet material produced using the method.

A device and method for producing a continuous strip-shaped composite material including a base material of metal, which is unwound in the form of a metal strip by a first coil-unwinding apparatus, and at least one cladding material of metal, which is unwound in the form of a metal strip by a second coil-unwinding apparatus. The metal base and cladding metal strips unwound by the respective coil-unwinding apparatuses are brought together in the hot state of at least 720 degrees Celsius. The unwound base and cladding metal strips brought toward each other and are joined by hot-rolling such that a single continuous strip-shaped composite material is thereby formed by roll cladding such that the composite material includes the base material and the cladding material.

The prediction system of strip chew collects and stores first data and second data as adaptive model construction data. The first data indicates the occurrence or non-occurrence of the strip chew in an object rolling path and the occurrence point of the strip chew. The second data includes information on a preceding rolling path and attribute information on an object strip. The system constructs an adaptive model using the stored adaptive model construction data, and stores the constructed adaptive model as an adapted model. The system collects prediction data similar to the second data. Then, the system inputs the prediction data to the adapted model to predict the occurrence or non-occurrence of the strip chew in the object rolling path and all or some of the occurrence points of the strip chew before the prediction object strip reaches the object rolling path.

A method for producing steel strip, in particular hot strip in the form of coiled coils or in the form of folded individual sheets, in which a steel melt is first produced, this is then formed into a strand in a continuous casting system, the strand is then fed into a heating unit and the heated strand is then rolled into hot strip in a subsequent rolling mill. The casting of the strand, the passage through the heating unit, and the rolling take place in a continuous process. To be able to produce hot-rolled steel strips in the most energy-efficient way possible and to make these strips available for further processing into high-quality cold-rolled and, if necessary, coated strips, the invention provides that, first of all, a steel melt is produced.
