Definitions
- the invention relates to an apparatus for producing a metal strip by continuous casting, with a casting machine, in which a slab is cast, wherein in the conveying direction of the slab behind the casting machine at least one milling machine is arranged in the at least one surface of the slab, preferably two opposing surfaces , can be milled off. Furthermore, the invention relates to a method for producing a metal strip.
- Continuous casting of slabs in a continuous casting plant can result in surface defects such as oscillation marks, casting powder defects or longitudinal and transverse surface cracks. These occur in conventional and thin slab casters. Depending on the intended use of the finished strip, therefore, the conventional slabs are partially flamed. Some slabs are generally flamed on customer request. The demands on the surface quality of thin slab plants are continuously increasing.
- flaming for surface treatment, flaming, grinding or milling are suitable.
- the flame has the disadvantage that the melted material can not be melted down again without treatment due to the high oxygen content.
- metal splinters mix with the grinding wheel dust, so that the abrasion must be disposed of. Both methods are difficult to adapt to the given transport speed. It therefore offers a surface treatment by milling.
- the hot milling chips are collected and can be packaged and smelted without processing without problems and thus add back to the production process.
- the cutter speed can be easily set to the transport speed (casting speed, finishing line feed speed).
- the device according to the invention of the type mentioned above therefore depends on the milling.
- a device of the type mentioned above with a milling machine, which is arranged behind a continuous casting plant is known. Reference is made to CH 584085 and to DE 199 50 886 A1.
- the surface treatment and the associated facilities are not limited to thin slabs, but can also be used inline behind a conventional thick slab caster and in slabs cast with a thickness of greater than 120 mm up to 300 mm.
- the inline milling machine is generally not used for all products of a rolling program, but only for those where higher surface requirements are required. This is advantageous for application reasons and reduces the Fräsmaschinenabpart and is therefore useful.
- the present invention is therefore based on the object to improve an apparatus for producing a metal strip by continuous casting using a milling machine so that the disadvantages mentioned are reduced. So it should be created a device with which the or the milling tools are protected even with prolonged use time and processing of the hot slab so that longer life can be achieved.

- the means for cooling the milling cutter for subcooling the slab surface are designed shortly before the milling process.
- a scale washer can be arranged between the milling machine and in front of a rolling stand.
- a preferred solution provides that the Zunw scrubber is single-row.
- the method for producing a metal strip by continuous casting by means of a device of the type described is characterized in that before and / or behind the milling machine, the slab temperature is measured on the top and / or bottom of the slab, with a operated in a machine control process model in Depending on the determined temperatures, the amount of coolant is determined with which the slab is cooled.
- the cooling of the slab on the top and bottom of the same can take place according to further education.
- An alternative embodiment of this method provides that the slab is cooled and the amount of coolant for cooling the slab is determined by a process model operated in a machine control, wherein the process model determines the amount of coolant as a function of the chipping volume milled by the slab.
- the determination of the amount of coolant can continue taking into account the slab transport speed and / or taking into account the temperature of the surface of the slab and / or taking into account the nature of the material of the slab.

- the water can be collected in a gutter.
- cooling water is injected tangentially to the cutter blades and collected in the gutter behind it, so that it can drain laterally next to the belt in the sintering channel.
- This cooling can also be combined with the cooling of the roller mill bearing with water.
- the amount of cooling medium for the cutter 6 is controlled in dependence on the milling removal or the machined volume.
