Definitions
- the present invention relates to a roll for a metallurgical plant, such as a strand guide roll for
- Guiding a metallic strand, preferably of steel, in a continuous casting machine or a guide roll for guiding a metallic strip in a hot rolling mill or through a metallic bath, preferably of zinc, for electroplating the strip, comprising:
- roller shell surrounding the roller axis.
- the invention expressly does not relate to a
- Casting roll for strip casting of a metallic strip by two counter-rotating casting rolls. The pouring of a
- twin roll casting Metallic strip through two casting rolls is referred to as twin roll casting.
- a casting mirror is formed between two driven casting rolls and at the narrowest point (English, klsslng polnt) between the casting rolls from a solidified strip, which is pulled out by continuous.
- the quality of the strand or the band can be improved, in the other case, an undesirable thermal expansion of the role can be compensated or reduced.
- the object is achieved in the aforementioned role in that the roller shaft is connected to the roller shell at one point, preferably at least two points, via a ring and the ring is a heating element
- the height H of the ring can be changed by ⁇ by heating the heating element. Due to the heating element, the temperature and consequently the
- a ring with heating element is very simple and robust and particularly insensitive to high
- Heating element spatially at least partially, preferably
- the invention is not limited to rollers with a continuous roller axle and can be applied in the same way also for rollers in which the roller axle is formed from two stub axles.
- roller axle a It is expedient if the roller axle a,
- Roller axis is arranged a water guide for guiding the coolant, wherein preferably the coolant in the axial Direction, particularly preferably spirally in the axial and radial directions, along the inner surface of the roll shell can be performed.
- the roller has a temperature sensor for
- Temperature sensor is integrated and preferably the
- the Amplifier is cooled by the cooling medium. Thereby, the signal level of the temperature signal (e.g., the voltage value of a thermocouple) can be increased, so that the
- the point at which the roller axle is connected to the roller casing via a ring is arranged in an end region of the roller casing. Since usually a symmetrical profile of the strand or the band is desired, it is advantageous if the roller axle are connected to the roller shell via two rings, the
- Strand guide roller with two bearings without bearing blocks 2 shows a schematic representation of the extent of a ring through a heating element
- Fig 3 a ring with heating element
- Figure 4 an electric heating element with electr. insulation
- the roller 1 in a sectional view, which leads a semi-solid strand 30 made of steel with a liquid core 31 in a continuous casting machine.
- the roller 1 is rotatably supported by two bearings 20 - here rolling bearings - which are supported on bearing blocks, not shown.
- the rotatable, continuous roller axle 2 has a central channel 8 for guiding a cooling medium 40 such as water; the path of the cooling medium through the internally cooled roller 1 is shown by arrows.
- a cooling medium 40 such as water
- the path of the cooling medium through the internally cooled roller 1 is shown by arrows.
- Between the rotatable roller shaft 2 and the cylindrical roller shell 3 are four rings. 4
- each ring 4 is supplied via a slip ring 6 and a line 7 with electrical energy, so that the temperature of the ring 4 can be accurately adjusted.
- the height change ⁇ of the ring 4 can be precisely adjusted so that e.g. an undesirable deflections of the
- Roll shell 3 due to the ferrostatic pressure of the strand 30 and the temperature-induced strain can be reduced or compensated.
- three plugs 9 are arranged inside the central channel 8, so that the cooling medium is forced to flow through the substantially radial stub lines 10 to the water jacket 11 around there maximum amount of heat from the red-hot strand 30
- the ring with the roller shaft 3 and the roller shell is connected by a respective interference fit.
- Coefficient of thermal expansion may be of interest as materials for the ring 4, especially as e.g. Mg has more than twice the thermal expansion coefficient as pure Fe.
- FIG. 3 schematically shows a segment of a ring 4 with an integrated electrical heating element 5a.
- Heating element 5a is completely integrated into the ring 4 and made helical.
- Figure 5 shows the upper half of a roll for guiding a belt through a zinc bath in one
- Roller 1 - connected to the roller shell 3 via a ring 4 with a heating element 5.
- a heating element 5 By heating the ring 4 by means of the electric heater 5 can turn the Height of the ring can be adjusted so that, for example, the deflection of the roll shell 3 can be compensated or reduced.
