Definitions
- the invention relates to a device for hardening rolling stock with a large longitudinal extension at a high throughput. More precisely defined, the invention relates to a device for the thermal annealing of at least parts of the cross-section over the longitudinal extent of profiled rolling stock produced in sequence from the rolling heat, in particular for hardening at least the head of rails with a length of more than 50 m and subsequent cooling to room temperature, consisting essentially of a roller table, a means for axially aligned alignment of the rolling stock, a means of transport with a support for the rolling stock for transverse placement thereof, a hardening device with a manipulation arrangement and a cooling bed.
- a rolling stock is usually subjected to a thermal heat treatment, which is advantageously carried out using the rolling heat.
- This tempering which essentially increases the mechanical properties of the material, such as hardness, abrasion resistance and the like, can be carried out over the entire cross section or, as is customary in the case of a running rail, only over partial areas of the same.
- the rolled material or parts of its cross-section in the austenitic structural state are immersed in a cooling medium over the entire length, and a structural transformation in the desired manner is achieved in this way.
- the thermal tempering requires a corresponding immersion time or dwell time in the cooling liquid, so that the throughput is limited by the tempering device.
- the maximum possible throughput through a diving compensation system with one Cooling basin limits the performance of the upstream rolling device.
- the invention now aims to avoid the shortcomings and, in particular, the economic disadvantages of known thermal treatment devices for rolling stock of the type mentioned at the outset and to provide a device which ensures high quality and good usage properties of the rolling stock which is being passed through, and which has a high performance and it makes it possible to treat rod material manufactured in sequence, in particular rails with lengths over 50 m, from rolling mills with high output using the heat of the roll and to heat treat them.
- the roller table has a device for positioning the rolled material lying in at least one cross-sectional area lying in the longitudinal direction and an associated alignment means that the hardening device is arranged from at least two next to each other with in the longitudinal direction substantially parallel to the alignment means
- Liquid cow devices with manipulators for moving the rolling stock is formed in such a way that, in addition to and parallel to the longitudinal extent of the liquid cow devices, the laying area of the cooling bed is located and that the transverse transport means at least two simultaneously has movable arms between the roller table rollers, each with rolling stock supports arranged on the end, these supports can be moved, lowered and raised in the transverse direction on the support arms in the transverse direction from the straightening position in the area of the roller table to the support area of the cooling bed, so that only the supports the conveying plane of the roller table or protrude over the upper edge of the roller table.
- rolling stock can be positioned with high accuracy and axially straightened in a simple manner with the device in sequence in the transverse transport region of the roller table, with the rolling stock supports of the transverse transport means simultaneously, i.e. without impairing the setting and the axial straightening process , a previously directed and provided rolling stock can be brought into the storage areas of the cooling devices or from these into the support area from the cooling bed or from the roller table directly onto the cooling bed. It is important that only the rolling stock supports of the supporting frame of the transverse transport means movable between the rollers can be raised above the upper level of the roller table rollers or their conveying plane.
- the device it is possible to arrange at least two hardening devices on one side of the roller table, so that a cooling bed is only to be provided on one side, which brings economic advantages.
- a rolling stock positioned on the roller table and aligned in line with the axis can be lifted off the support arms by the supports and placed, for example, in a storage area of a liquid cooling device, which is designed as a manipulator.
- the transverse transport means is released for further transverse rolling material transports, the manipulator setting up the deposited rolled material alone and automatically in its cross-sectional position, at least partially introducing it into the cooling medium, lifting it out and transporting it to the
- the dwell time can be reduced in a favorable manner the track on the roller table is shortened, the temperature control is improved and the system output is increased if necessary.
- This position is particularly well suited to Weiers for a so-called "head down" vertical position of the rail by means of the manipulators.
- the liquid cooling devices are designed as plunge pools which have horizontally and vertically oriented stops for leveling and aligning the rolling stock on the bottom side and optionally laterally, in particular when parts of the cross section of a rail are cooled down a very constant cooling and hardness distribution can be achieved over its length, which promotes quality assurance of the product.
- hold-down means for the rolling stock in particular for a rail, are provided in the device, with which means the rolling stock / rail can be pressed against the leveling stops in the plunge pool during cooling, because this results in cooling caused curvature effectively prevented and the respective local cooling of the surface can be kept completely the same.
- Rolld goods support 1 shows a device according to the invention with a hardening device 3 consisting of two liquid cooling devices 31 and 32, which are arranged between a roller table 1 and a cooling bed 4.
- the head of the rail S is immersed in a cooling liquid 315 in one of the liquid cooling devices 31.
- the l rail can be positioned in a plunge pool 312 by hold-down means 314 and leveling stops 313 in such a way that the head is only forced to cool.
- a second liquid cooling device 32 is on standby.
- a rail S coming from a roller mill (not shown) is positioned on the roller table 1 and can be aligned by means of an alignment means 2 with an alignment ruler 21 if necessary.
- a transverse transport means 5 with support arms 51 and in each case one rolling stock support 52 is arranged to be traceable into the area of the roller table 1.
- a positioned and axially aligned rail S which advantageously lies in two cross-sectional areas on the conveying plane 11 of the roller table 1, can now be lifted vertically and essentially in this position by means of the rolling stock support 52 horizontally or transversely to a liquid cooling device which is on standby, in FIG. 1, position 32.
- Such a cross-sectional position of the rail S on the rolling stock supports 52 is favorable for the transfer thereof and a "head down" vertical position by a manipulator 321, by means of which the rail head can also be lowered or introduced into a coolant 325.
- the rail head can also be lowered or introduced into a coolant 325.
- the latter can be clamped in for the purpose of stabilization by means of hold-down means 324 and leveling stops 323.
- a follower rail can be brought from the rolling mill to the roller table 1 and set up and aligned thereon.
- a rail S can be brought out of the liquid devices 31, 32 by means of manipulators 311, 321 and removed by the rolling material supports 52, essentially in the same way, after which they are brought and placed on the storage area 41 of the cooling bed 4.
- the hardening device 3 can also be designed with more than two liquid cooling devices; at most, a programmable control unit can advantageously be used for a production process.
