Definitions
- the invention relates to a method for producing metallic strips using casting rolls, in which a slab is first cast in a casting machine, the slab being cleaned in a cleaning device in the conveying direction behind the casting machine and the slab is then subjected to a heat treatment in a heat treatment device, the Slab between the cleaning device and the heat treatment device is subjected to a smoothing process by means of two interacting smoothing rollers.
- the slab is either already in the area of the casting machine, i.e. before it enters the furnace. H. subjected to a relevant thickness reduction when the core of the casting strand is still liquid, or between the casting machine and the furnace in a roughing stand.
- the technological focus here is on improving the profile or geometry of a cast strip or a very thin slab.
- the invention is based on the task of developing a method of the type mentioned in such a way that the problem mentioned is eliminated.
- energy and production costs should be reduced, which should be achieved by specifically influencing the slab and strip edge geometry.
- the surface of the slabs should be improved before the first forming.
- the solution to this problem by the invention is characterized in that the smoothing process is carried out in such a way that the slab does not experience a significant reduction in thickness and the roughness of the smoothed surfaces of the slab is reduced.
- the average roughness value of the rolled surfaces of the slab after smoothing is preferably at most 10 pm, particularly preferably at most 8 pm. This means that the average roughness value is reduced compared to the usual value when casting from a mold (approx. 11 pm to 14 pm).
- the slab is preferably subjected to the smoothing process in a fully solidified state.
- the reduction in thickness of the slab during the smoothing process is preferably less than 10%, particularly preferably less than 5% and most preferably less than 3%.
- the smoothing process is carried out with two cooperating smoothing rollers, which preferably exert a force acting normally on the slab between 3,000 kN and 5,000 kN, and particularly preferably between 3,500 kN and 4,500 kN.
- the smoothing process with the two interacting smoothing rollers is preferably carried out in such a way that smoothing roller diameters between 500 mm and 700 mm, preferably between 550 mm and 650 mm, are provided.
- the cleaning process in the cleaning device is preferably a descaling process, in particular by fluid descaling or scarfing.
- the smoothing rollers can be cooled during the smoothing process.
- the smoothing process is preferably carried out at a speed between 1.0 and 6.0 m/min.
- the pair of smoothing rollers used for the smoothing process described can be adjusted to the slab thickness.
- the applied force can be adjusted using a process model.
- the parameters for setting the smoothing rollers are transmitted via a control device.
- the pair of smoothing rollers is therefore not a full-fledged rolling stand with corresponding actuators.
- the design of the diameter and optionally the shape of the bale also depends on the bandwidth.
- the proposed procedure results in significant advantages, which initially lie in the reduction of scale formation, which results from the reduction in surface roughness and thus the avoidance of running marks on the slab.
