Definitions
- the present invention relates to a strand guide roller for guiding a steel strand in a continuous casting machine and a method for cooling the strand guide roller in the
- a cooled strand guide roller in which a cooling medium first cools a bearing in a left bearing block, the cooling medium flows from the left bearing block through the roller to the right bearing block, and there again a bearing cools.
- the cooling medium has to be introduced from a bearing block in each case via a rigid or flexible connecting piece and a rotary feedthrough in the role or on the opposite side again. This restricts the robustness of the roll. How the design can be simplified, so that can be dispensed with in particular sensitive rotary unions, is not apparent from the Scriptures.
- the object of the invention is to present a cooled strand guide roller for guiding a steel strand in a continuous casting machine, which is characterized by a particularly simple design and particularly robust and
- a further object of the invention is to present a method for cooling a strand guide roller in a continuous casting machine, in which the cooling medium cools the two bearing blocks, and the cooling medium cools the bearings and the cylindrical roller shell of the roller on the way between the two bearing blocks.
- a so-called "peripherally cooled" strand guide roll is created which, due to the compactness and reliability, is also suitable for billet, billet and profile strand casting machines.
- a strand guide roller for guiding a steel strand in a continuous casting machine comprising:
- Wasserleitmantel cooling water from a left cavity between the axis and the Wasserleitmantel in the region of the left bearing in a longitudinal space between the Wasserleitmantel and the roller shell, along the longitudinal space in the axial and radial direction, and from the longitudinal space in a right cavity between can guide the water duct and the axle in the area of the right bearing.
- the torsionally rigid connection can for example be positive (eg by a feather key) or non-positively (eg by a shrink or press-fit connection or by friction).
- the left bearing is cooled by the cooling water in the left cavity.
- the surface of the cylindrical roller mantle is cooled by the cooling water in the longitudinal space, whereby a particularly uniform temperature distribution is achieved by guiding the cooling water in the axial and in the tangential direction. Finally, the right bearing is cooled by the cooling water in the right cavity.
- the Wasserleitmantel can be made particularly simple and efficient sheet metal parts, if it has:
- a cooling medium is introduced from a left cavity between the Wasserleitmantel and a stationary axis in a longitudinal space between the roll shell and the Wasserleitmantel, performed in the longitudinal space in both the axial and tangential direction, and from the longitudinal space in a right cavity between the Wasserleitmantel and the stationary axle. This not only ensures a particularly even distribution of the surface temperature of the roll mantle, but also the left and right bearings cooled.
- the cylindrical tube, the tangential outer webs and the axial outer web are preferably bent sheet metal parts, wherein the outer webs are connected by joining (eg., Soldering, welding or gluing) to the pipe.
- An alternative water-conducting jacket points to:
- At least one spiral-shaped outer web which extends on the outer circumferential surface of the tube at least once spirally around the longitudinal extent of the tube.
- the cooling medium is passed through at least one, possibly a plurality, spiral outer web in the tangential and axial direction along the roll shell, which also has a very uniform distribution of the surface temperature on the
- the spiraled outer land can either be joined to the pipe by joining, or machined out of the pipe by milling or turning. It is particularly expedient if the Wasserleitmantel has at least one, preferably two or more, inner web, which extends from the inner circumferential surface of the tube in the radial direction to the stationary axis. This prevents a so-called “hydraulic short circuit" between two cavities located between the left end portion of the axle and the roller shell and the right end portion of the axle and the roller shell to flow right cavity, whereby a high heat dissipation is ensured by the cast product.
- the left and the right bearing block each have a bore for receiving the stationary axle wherein the bearing block has at least one, preferably closed, cavity in the tangential direction around the bore.
- the cavity in the bearing block which is flowed around by the cooling medium, both the bearing block itself and a sealing element for the sealing are cooled to the outside.
- the cavity in the bearing block has a substantially radial stub for guiding the cooling water from the bearing block in the axis.
- a radial stub has the shortest length, it is not necessary for the stub to be exactly radial.
- each half of the stationary axle has in the longitudinal direction a separate axial line for conducting the cooling medium and a radial branch line connected thereto into a cavity.
- At least one sealing element is provided in each case.
- a simple fluid-tight seal may e.g. by a so-called Prelonring (see, for example, WO 2011/117383 Al for the execution of seals in strand guide rollers with
- Prelonringen by sealing rings or by rotary seals such as slip rings.
- the protection of the bearing from the environment can be done, for example, by radial shaft seals or labyrinth seals.
- radial shaft seals or labyrinth seals are also known to the person skilled in the art.
- the second object is achieved by a method for cooling a strand guide roller in a continuous casting by a cooling medium, wherein the strand guide roller
- the cavity has a left cavity, a longitudinal space, and a right cavity, wherein
- the cooling medium from the left cavity flows into a longitudinal space between a Wasserleitmantel and the roller shell;
- the cooling medium flows through the longitudinal space in the axial direction; and subsequently
- the cooling medium flows from the longitudinal space into the right-hand cavity.
- a so-called peripherally cooled strand guide roller is formed.
- the cooling medium as it flows through the longitudinal space, performs a tangential movement about the stationary axis in addition to the axial movement.

- a cooling medium for example water
- the cooling water as shown by the lower arrow, from below into the bearing block 10b and flows in a vertical direction upwards. Subsequently, the cooling water is deflected four times by 90 °, so that the cooling water in a closed cavity 14, the stationary axle 11 can flow completely around. This ensures uniform cooling of the axle 11 or of the roller mantle 12 connected to the axle.
- the cooling water can enter from the cavity 14 via a radial stub 15 in an axial line 22 within the axis 11.
- FIG. 4 shows that the cooling water from the branch line 15 is delimited via an axial line 22 and a radial bore into a cavity 14, 14a, which is bounded by the stationary shaft 11, the rotatable bearing housing 23, and the water-conducting jacket 1. can occur.
