Definitions
- the present invention relates to a device for projecting a refractory lining according to the preamble of claim 1.
- the invention also relates to the method for implementing the device according to the invention.
- a coating method which consists in casting the coating composition in the space between a template and the interior surface of the container to be coated.
- a robot comprising articulated arms, the movements of which are controlled remotely.
- a projection device comprising a beam fixed above a small transfer container along the longitudinal axis thereof, on which is movable in translation, a carriage carrying the projection lance of the coating.
- This device is economical, but can only be suitable for small metallurgical vessels. In addition, it does not allow the coating to be projected at a constant distance between the head of the spray lance and the interior faces of the container, so that the compactness of the coating is irregular, which is unacceptable.
- This device is not particularly suitable in the case of transfer containers having non-parallelepiped geometric shapes and whose side walls are not vertical but inclined.
- the object of the present invention is to remedy the drawbacks of known embodiments by creating a projection device of simple construction and inexpensive and which makes it possible to obtain a coating of regular compactness whatever the dimensions and the shape of the transfer containers.
- the device contemplated by the invention for spraying a coating on the internal faces of a liquid metal transfer container comprises a spray lance fixed vertically to a carriage movable in a horizontal plane situated above the transfer container.
- this device is characterized in that the carriage is movable in translation on a guide extending in a first longitudinal or transverse direction of the transfer container, in that this guide is itself movable in translation on guide means extending in a second transverse direction relative to the aforementioned direction, in that these guide means are themselves mounted on a support movable in translation in the longitudinal direction of the container, and in that means are designed to control the various movements of the spray lance so that the spray head is kept at a substantially constant distance from the side faces or the bottom of the transfer container.
- this device can have a smaller overall dimensions than the length of the container and it can therefore be suitable for both transfer of small and large dimensions.
- the carriage is movable in a direction transverse to the length of the container, it is possible to adjust the distance between the head of the spray lance and the side wall of the container, even when the latter is not vertical , but inclined or not parallel to the longitudinal direction of the transfer container.
- the projection lance is movable in rotation and in translation along a vertical axis.
- the support of the device is movable in translation on guide means extending parallel to the longitudinal direction of several transfer containers arranged in a row.
- the same simple, space-saving and inexpensive construction device can thus be coated in series with several casting distributors arranged in a row.
- a device 1 for projecting a refractory and / or thermal insulating and / or water-repellent coating on the interior faces of a flow distributor 2.
- This coating can be permanent or be a coating of wear.
- This projection device comprises a projection lance 3 fixed vertically to a carriage 4 movable in a horizontal plane situated above the casting distributor 2.
- the lance 3 is connected to a flexible tube 5 which is itself connected to a machine for preparing and pressurizing a coating composition in the form of mud, as described for example in French patent applications No. 8704694 of April 3, 1987 and 8711466 of August 12, 1987 in the name of the applicant.
- the carriage 4 is mounted movable in translation on a guide 6 extending in the longitudinal direction D of the tundish 2.
- This guide 6 is itself movable in translation on guide means 7 s' extending transversely to the above-mentioned longitudinal direction D.
- These guide means 7 are themselves mounted on a support 8 movable in translation in the longitudinal direction D of the tundish 2.
- Means 9, such as a microcomputer associated with motors are provided for controlling the various movements of the projection lance 3 carried by the carriage 4, so that the head 3a of this lance is kept at a substantially constant distance from the faces side 2a and 2b and the bottom 3c of the transfer container.
- the projection lance 3 is also movable in translation and in rotation along a vertical axis (see arrows F1 and F2 of the figure 2.
- the guide 6 extending in the longitudinal direction D is a beam on which the carriage 4 is mounted movable by means of rollers 4a.
- the opposite ends of the beam 6 comprise two carriages 6a, 6b fitted with rollers, mounted movably on two crosspieces 8 extending perpendicular to the longitudinal direction D of the tundish distributor 2.
- the opposite ends of the crosspieces 8 comprise rollers 10 which are mounted on two guide rails 11 which extend respectively on either side of the longitudinal lateral faces 2a of the tundish distributor 2.
- the two cross members 8 are interconnected by side members 12 fixed to the ends of these cross members 8 so as to create a rigid frame.
- the length of this chassis is substantially equal to half the length of the casting distributor 2, while its width is slightly greater than the width of this distributor.
- the device 1 is mounted on rails 11 extending parallel to the longitudinal direction D of several casting distributors 2, 2A, 2B, 2C arranged in a row.
- These guide rails 11 extend beyond the end of the tundish 2C located at the end of the line, so as to constitute a parking area 11a of the device 1, released from the upper opening of the tundish.
- the movements of the entire device 1 on the rails 11, of the carriage 6a, 6b of the beam 6, of the carriage 4 on the beam 6, the translation and the rotation of the lance 3 carried by the carriage 4 are automatically controlled using the microcomputer 9 according to a predetermined operating cycle which ensures that the head 3a of the lance 3 remains at a constant distance from the internal surface of the tundish distributors 2, 2A, 2B, 2C.
- the end positions of movement of the device on the rails 11 can be determined by electrical contactors 13 (see FIG. 1), stopping the operation of the drive motor of the device when the latter reaches a position in which it is capable of coating half the interior surface of a tundish.
- the device 1 will occupy two successive positions, namely that represented in solid lines in FIGS. 1 and 2 and that represented in dotted lines in FIG. 1.
- the carriage 4 is mounted movable in translation on a guide 106 extending in the transverse direction L of the tundish distributor 2.
- This guide 106 is itself movable in translation on guide means 107 extending in the above-mentioned longitudinal direction D.
- the guide means 107 are themselves mounted on the side members 12 which constitute, with the crosspieces 8, as in the first embodiment described above with reference to FIGS. 1 and 2, a support that can move in translation in the longitudinal direction D of the tundish 2.
- the device 1 is moved on the rails 11 to place it in position above the casting distributor 2, as shown in FIG. 1.
- the head 3a of the lance 3 can sweep the entire interior surface of the distributor over half of its length.
- a longitudinal lateral face 2a and a transverse lateral face 2b are coated by projecting successive parallel and contiguous strips such as b3 (see FIG. 5).
- the head 3a of the lance is brought to the desired distance d from the wall 2a, the carriage 4 is moved in the direction F4 parallel to the length D.
- the head 3a is turned by 90 ° and the carriages 6a, 6b are moved in a direction perpendicular to D.
- the next tape is projected in the same way. Since the side walls 2a and 2b are inclined, the distance d between the head 3a and the interior surface of the distributor is maintained by means of the carriages 6a, 6b (for the wall 2a) and the carriage 4 (for the wall 2b) .
- the implementation of the projection device according to the second embodiment of the invention is entirely comparable to what has just been described, the carriage 4 moving on the beam 106 in the direction L transverse to the flow distributor 2, the beam 106 moving itself on the longitudinal guides 107.
- the device despite its small dimensions, is able to coat the interior of several flow distributors in a row.
- the structure of the device can be modified provided that the various fundamental movements of the carriage 4 are preserved.
- microcomputer 9 can be replaced by remote controls operated manually by an operator, or installed in parallel with such controls.
- the length of the side members 12 may be different from that indicated above, and it can be made so that the lance 3 can turn on itself by several quarter turns successive.
- the implementation of the device and that of the coating may be different from those described.
- the width of the flow distributor 2 and the conditions for projecting this coating lend themselves to it, it may be possible, in particular with the device according to the first embodiment, the device being placed at one end of the distributor, coat, without moving the carriage 4 or the beam 6, the transverse face 2b and the start of the two longitudinal faces 2a by simply rotating the projection lance 3, and possibly by adjusting its level in height, and finishing the coating by moving the carriage 4 longitudinally along the beam 6 and the latter along the rails 11.
