Cutting position control device
A cutting position control device according to an embodiment includes an arithmetic processing circuit that receives an input of first data relating to a production schedule and material information of a material to be produced, uses the first data to calculate a first cutting position of a first cutter for a first slab cast by continuous casting equipment, generates a first parameter for setting the first cutting position for a control program introduced to a process control device, and determines whether or not to use a second cutter to further cut a second slab of a second length cut from the first slab based on the first parameter by comparing the second length and a first length set to be from a front end of the first slab to the first cutting position, wherein the second cutter is located downstream of the first cutter.

Device and method for producing hot-rolled metal strips
A device for producing hot-rolled metal strips has a casting machine that produces and transports slabs in a transport line of the casting machine. A rolling mill forms the slabs into corresponding metal strips during transport along a transport line of the rolling mill. A combination transport and temperature-influencing device is arranged between the casting machine and the rolling mill transports the slabs at least along the transport line of the rolling mill, feeds the slabs to the rolling mill and sets the temperature of the slabs to a rolling temperature. A surface device is arranged between the casting machine and the combination transport and temperature-influencing device and processes and/or treats and/or inspects at least one of the surfaces of the slabs. A temperature-influencing device is arranged between the casting machine and the combination transport and temperature-influencing device and modifies the temperature of the slabs.
Method for machining a metal cast strand of round cross-section by reducing the cross-section in the final solidification region
The system described herein relates to working a metal casting strand that is round in cross-section, by reducing the cross-section in the final solidification region with the aid of at least three forming tools which are distributed around the circumference and act simultaneously on the casting strand. In order to provide advantageous working conditions, the casting strand is formed by forging tools constituting the forming tools in a longitudinal portion for each forming stroke, which portion corresponds to at least a fourth of the strand diameter before the reduction in cross-section. The forging tools are rotated by an angle step about the axis of the casting strand 1 between the forming strokes.
Method for producing metal strips by continuous casting and rolling
A method relates to producing metal strips by casting rolling. A slab (3) is first cast in a casting machine (2). The slab (3) is cleaned in a cleaning device (4) placed after the casting machine (2) in the conveying direction. The slab (3) then undergoes a heat treatment in a heat treatment device (11). Between the cleaning device (4) and the heat treatment device (11), the slab (3) undergoes a smoothing process by means of two interacting smoothing rolls (13, 14). In order to reduce energy and production costs and to improve the surface of the slabs prior to the first forming process, the smoothing process is carried out such that the slab (3) does not undergo a substantial reduction in thickness, and the roughness depth of the smoothed surface of the slab (3) is reduced.
