Description

  The present invention relates to a slide valve device and a refractory replacement method thereof. The present invention relates to a novel improvement for facilitating replacement of a refractory (not shown) such as a slide plate by moving to an open position.

  Conventionally, as this type of slide valve device used, the slide case of the slide valve device attached to the molten metal storage container is manually opened and closed. On the other hand, a slide valve device that opens and closes a slide case using a slide case drive device as in Patent Document 1 has also been invented.

JP-A-9-206922

However, since the conventional slide valve device is configured as described above, the following problems exist.
That is, in the above-described conventional configuration, the slide case is vertically opened through the hinge, and its weight is 30 kg or more. When opening, it becomes a heavy work for the operator, and the ladle and tundish are reused hot. Was a hot hot work.
In addition, this slide case is lowered by its own weight due to its weight, so if the operator's hand slips and the hand moves away from the slide case, it can fall quickly and become a serious safety issue. There was also sex.
On the other hand, the slide valve device that opens and closes the slide case using the slide case drive device of Patent Document 1 has problems in stability of operation and safety during casting.
In the opening / closing mechanism of Patent Document 1, the slide case is opened and closed by engaging a roller with a U-shaped recess provided in the frame of the slide case. In this system, high dimensional accuracy is required to reliably open and close, but the slide valve device is repeatedly subjected to repeated heating and cooling with molten steel for a long time. Therefore, the dimensional change due to expansion and contraction is repeated many times, and as a result, there is a possibility that the alignment is slightly shifted while the slide valve device is used. Therefore, even if the opening / closing mechanism operates reliably in the initial stage of use of the slide valve device disclosed in Patent Document 1, normal operation may be hindered due to misalignment as the slide valve device continues to be used.
Moreover, in the opening / closing mechanism of Patent Document 1, there is a risk that the slide case may be accidentally opened while the slide valve device is attached to the molten steel container and cast. If the slide case of the slide valve device is opened with the molten steel in the molten steel storage container, the molten steel in the storage container may flow out at a stroke, resulting in an accident. In the detailed description of Patent Document 1, there is a description of a stopper for the purpose of preventing the drive device from moving to a position where the slide case is opened. However, there is a risk that the stopper may be opened during casting due to a failure of the stopper or an operation error. As long as there is a certain point, the above point is inevitably an essential problem regarding the safety of Patent Document 1.

The slide valve device according to the present invention is provided at the outlet of the molten metal container to control the flow rate of the molten metal, and when the refractory is replaced, the molten metal container is turned over or tilted, the seal case is opened, and the slide plate is refractory. In a slide valve device in which a slide case to which an object is attached is rotatable through a hinge portion connected to a connecting body of a driving device having a rod, the driving device is configured to rotate when the molten metal container rolls over or tilts. positioned below the hinge, the previous SL connecting body has the rod and closest is pulled into the drive position, the support member located in a position distant to the drive unit than the hinge portion and, moving the slide case by the driving device, the slide case by moving to a position where the hinge portion is separated to the drive device is self Or rotation by the spring, becomes open position while being supported by the supporting member, wherein a configuration was to exchange the slide plate refractory, also, when the slide case is rotated to the open position, the connecting The support member is arranged at a position where the angle between the center line of the body and the slide case is 150 ° to 80 °, and the support member is in contact with the slide case. The portion is made of a rotatable member, and the refractory replacement method for the slide valve device according to the present invention is provided at the outlet port of the molten metal container to control the flow rate of the molten metal. The molten metal container is turned over or tilted, the seal case is opened, and the slide case with the slide plate refractory attached is connected to a drive unit coupling body having a rod. Using a slide valve apparatus rotatable through a di-section, wherein at the time of rollover or tilting of the molten metal container, wherein the drive unit is positioned below the hinge, before Symbol connecting member is a drive device A support member is located at a position closer to the drive device than the hinge portion at a position where the rod is retracted closest, the slide device is moved by the drive device, and the hinge portion is aforementioned rotation by sliding case its own weight or a spring by moving a position away to the drive apparatus becomes the open position while being supported by the support member, a method for exchanging the slide plate refractory, also When the slide case is rotated to the open position, the support body is positioned so that the angle formed between the center line of the coupling body and the slide case is 150 ° to 80 °. A method member used arranged, also, the support member, the contact portion between the sliding case is a method of using a universal member rotation.

Since the slide valve device and the refractory replacement method thereof according to the present invention are configured as described above, the following effects can be obtained.
That is, in the position where the support member such as a roller provided in the main body of the slide valve device is pulled away from the drive device, the support member such as a roller is located farther from the drive device than the hinge portion. When the rod is pushed out and the hinge part is moved away from the drive device rather than the support member (open position), the slide case is rotated by its own weight while being supported by the support member to reach the open position. As in the prior art, the operator does not need to perform hot heavy muscle work.
In addition, it is possible to remotely control the rotation of the slide case, and the safety during the refractory replacement work can be greatly improved.
Furthermore, since the opening / closing mechanism of the present invention does not require strict dimensional accuracy, there is no hindrance to its operation even if a deviation occurs due to repeated expansion and contraction.
In addition, since the slide case cannot be opened until after the seal case is opened, there is no possibility of accidentally opening the slide case during use of the slide valve device.

  The present invention has been made to solve the above-described problems, and when the slide valve device is not used during refractory replacement, the molten steel container is overturned or tilted to open the seal case, and then the drive device When the slide case is sent out, the slide case rotates and is supported by a support member provided in the slide valve device main body so as to be in an open position so that a refractory such as a slide plate can be easily exchanged for a long time. Provided is a slide valve device that has an opening / closing mechanism that can withstand use of the slide valve, and that does not accidentally open the slide case during use of the slide valve device (that is, during casting), and a refractory replacement method thereof. For the purpose.
