Definitions
- the invention relates to a method for repairing a refractory sleeve of a metallurgical vessel according to the preamble of claim 1 and a device for carrying out the method.
- Refractory sleeves of the type mentioned are, inter alia, the inner sleeves of molten metal containing Giesspfannen.
- the inner sleeve is inserted in a perforated brick of the refractory socket lining and externally connects to the closing plate of a slide fastener.
- the inner sleeve forms the pouring channel of the ladle and is therefore exposed during operation to a very strong wear. It is therefore often necessary to replace the worn sleeves with new unbroken sleeves.
- this process is usually very laborious, as you first need to break out the worn sleeve, repair the damaged seat of the hole, and then install the new sleeve so that it is properly centered in the vessel. This results in long downtime for the affected vessels.
- the invention has for its object to provide a method for repairing worn sleeves, that with this the reliability and dimensional accuracy of the repaired sleeves is guaranteed.
- This object is achieved according to the invention in that the sleeve repair is carried out by mortaring the casting channel of the sleeve with a mortar dispenser insertable into the casting channel in a manner known per se, calibrating the same over the entire channel length when it is withdrawn from the casting channel, the mortar dispenser being used during the Mortar is rotated coaxially to the casting channel and after a defined time also pulled out of the casting channel in rotation.
- the inventive repair method is characterized by the fact that it is feasible with a relatively small expenditure on equipment, because the rotating mortar dispenser accomplishes both the uniform mortaring of the channel wall and their accurate calibration.
- the method also has the advantage of a minimized expenditure of time, since it is practicable even at a still relatively high vessel temperature, and because both the mortaring and the hardening of the applied mortar composition take place rapidly.
- the method also makes it possible to automate the function of the mortar dispenser and adapt to relevant parameters, such as the nature of the sleeve or the mortar used in each case.
- the invention further provides that when the rotating mortar dispenser is withdrawn from the pouring channel, the mortar mass sprayed onto the channel wall is scraped off helically with the mortar dispenser, the rotational speed of the mortar dispenser being adjustable depending on the nature of the mortar and the structure and nature of the channel wall. In this way, the withdrawal of the mortar Facilitates the donor from the Giesskanal, and this receives at the same time a perfectly smooth inner wall.
- the invention also provides that the mortar of the sleeve at a tube temperature of preferably above 300 ° C is performed.
- the inventive device for carrying out the proposed method is characterized in that the mortar dispenser is formed by a rotating around the longitudinal axis tube member with radially longitudinal lamellae whose length corresponds to the Giesskanalin the sleeve to be repaired and its defined by the lamella outer diameter equal to the setpoint of Giesskanal mit- diameter of the sleeve is dimensioned.
- the helically rotating lamellae on withdrawal of the device cause an accurate calibration of the pouring channel with a perfectly smooth channel surface.
- FIG. 1 A ladle nozzle with a device for repairing the inner sleeve according to the inventive method shown schematically as a section;
- FIG. 2 shows the device of Figure 1 in a perspective view.
- Figure 3 is a section of the device of Figure 2 and the inner sleeve.
- FIG. 4 shows an angled section of a ladle nozzle, a sliding closure adjoining the inner sleeve at the ladle position of a casting installation; and
- FIG. 5 shows a perspective view of a variant of the device
- Fig. 1 shows a portion of a steel pan 1, the spout 2 may be provided with a slide closure, not shown.
- the steel ladle 1 has an outer steel casing 3 with a refractory lining 4, in which a refractory perforated brick 5 for receiving an inner sleeve 6 made of refractory material is installed.
- the sleeve 6 In operation, the sleeve 6 is exposed to its inner wall 6 'in the region of the casting channel 7 a strong wear. For this reason, it is no longer operational after a certain number of casts.
- the sleeve repair is carried out according to the invention by mortaring the inner wall 6 'of the sleeve 6 with a mortar dispenser 9 which can be pushed into the pouring channel 7, through which the mortar is conveyed outwardly into a cavity 14 between mortar dispenser 9 and the worn inner wall 6' of the sleeve 6 , After the subsequent withdrawal of the mortar dispenser from the casting channel 7, the sleeve is mortared and calibrated over the entire channel length with sufficient adhesive strength.
- the device 8 is according to the invention actuated so that the mortar dispenser 9 during the mortar relatively fast for a defined time rotates coaxially to the casting channel 7 and is pulled out of this also rotating during the curing of the mortar.
- the inner wall 6 'of the restored Giesskanals 7 evenly smooth processed and it is prevented when pouring that flowing melt is retained due to bumps and possibly sticks.
- the rotational speed of the mortar dispenser 9 corresponds for example to such a hand drill with about 500 to 1 Um00 revolutions per minute. It is shown coupled to the mortar dispenser drive shaft 1 9 for a rotary drive.
- the rotational speed of the device can be dependent be set by the nature of the mortar and the structure and nature of the channel wall.
- the mortar dispenser 9 consists of a cylindrical tube part 10 with radially longitudinal lamellae 1 1, wherein the length of the tube part corresponds to the casting channel length of the sleeve 6, during which the outer diameter defined by the lamellae 1 1. is dimensioned equal to the target value of the channel diameter of the inner sleeve.
- the slats 1 1 are aligned axially parallel to the tube part 10 and delimited at both ends by disc-shaped flanges 12, so that between the individual slats elongated spaces 1 3 are formed for receiving the refractory mortar.
- the mortar By rotating the tube part 10, the mortar is ejected from the free space 1 3 and uniformly applied to the worn inner wall 6 'of the sleeve 6 over the entire channel length, wherein the centrifugal effect contributes to the fact that the mortar firmly on the inner wall 6' and the educated Cavity 14 can adhere between them.
- the lamellae 1 1 are slightly convexly curved in the direction of rotation of the tubular part 1 0, so that the mortar is pushed outward beyond the outer edges 11 'formed, and these edges 1 1 'act cutting.
- the slats 1 1 co-rotating with the tube part 10 also serve to strip off the excess mortar and to calibrate the pouring channel of the inner sleeve without damaging the channel wall. This also applies when removing the device, because then the further rotation rende pipe part 1 0 performs a helical movement that significantly supports the deduction process.
- these free spaces 13 of the mortar dispenser 9 are dimensioned so that a predetermined amount of mortar can be filled by hand, for example, which corresponds approximately to the cavity 14 formed between the mortar dispenser and the inner wall of the sleeve, so that such stripping the mortar is made possible.
- These free spaces 13 are therefore filled with mortar in such a way that this mortar is filled almost flush with the outer circumference of the lamella 1 1 and thereby distributed evenly.
- the sleeve repair method according to the invention is particularly suitable for casting installations in which the maintenance and delivery of the sliding closure of the pans is carried out centrally by means of a robot in a maintenance station, the so-called pan pod.
- FIG. 4 shows the spout of a casting ladle 1 located in the service station, in the perforated brick 5 of which an inner sleeve 6 is inserted.
- the latter is connected to a sliding closure 20 known per se for closing and opening the pouring channel 7.
- the wear zone 1 5 extends from the free passage area of the perforated block 5 to the outlet of the inner sleeve 6, to which a refractory closure plate, not shown, tightly connects into the housing 21 of the sliding lock 20.
- the ladle 1 is located in Fig. 4 in the maintenance position in which it is laid horizontally.
- the sliding closure 20 is partially in Section with the usable in its mechanics refractory components, namely the closure plate, the slide plate and the spout, shown.
- the sleeve 6 of the ladle is freely accessible after pivoting the slide unit 16 of the slide fastener and the removal of the bottom plate, and can be repaired in the maintenance station, while the maintenance and delivery of the sliding closure is performed.
- the repair takes place there automatically, preferably with the robot used for the plate change.
- a suitable repair device 17 is shown. It differs from the device 8 of FIG.
- the device for coupling the device to the robot, it has a second pipe part 18 of a mortar supply device provided as an extension to the pipe part 10, which can simultaneously serve for supplying the other pipe part 10 with mortar.
- the repair device 17 is automatically positioned accurately with the robot and driven by its drive shaft 19 so that it is rotated in the casting channel 7 at the respectively optimum rotational speed.
- the device according to the invention can easily be carried out differently than in the described embodiment. The only thing that matters is that it works as described above.
- the sleeve repair method according to the invention is also suitable for other sleeves which are fastened in a refractory vessel lining and exposed to severe wear there, such as those in a tap of a converter, an electric furnace, or in a tundish.
- a refractory vessel lining and exposed to severe wear there, such as those in a tap of a converter, an electric furnace, or in a tundish.
- the method is particularly advantageous for repairing the inner sleeves of Giesspfannen because it offers the ability to quickly repair the inner sleeve in the course of the automation of the casting operation with each plate change and thus reduce the need for new inner sleeves, it eliminates the otherwise when changing the sleeve required cleaning on the perforated brick. The wear of the hole is reduced and there are no annoying sintering.
- the pipe part of the mortar dispenser could be provided with other means, which limit the free spaces, for example, thread-like elevations.
- this conveyance of the mortar to the inner wall of a sleeve could also be done by an outward pressing, for example by a cylindrical inflatable balloon-like body or the like.
