Description
Technical Field
The utility model relates to a continuous casting cutting device. In particular to a continuous casting cutting ignition device for a continuous casting cutting gun and an ignition gun.
Background
In the process of steelmaking and continuous casting cutting, in order to accurately synchronize the operation of a cutting gun with the production operation of continuous casting billets so as to ensure the normal operation of steelmaking and continuous casting production, the ignition reliability of the cutting gun is of great importance, and therefore, the ignition gun of the cutting gun must operate stably and reliably and ignite in time. The existing continuous casting cutting device has certain unreasonable structure of the electrode of the key device of the ignition gun and the whole arrangement structure of the electrode, so that the ignition reliability of the existing continuous casting cutting device is low, and the production stop of the continuous casting production process is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the problem that above-mentioned prior art exists, provide a continuous casting cutting ignition. The continuous casting cutting ignition device is extremely simple and reasonable in structure, timely in ignition and high in reliability.
The technical scheme of the utility model including ignition electrode and corresponding insulator arrangement, be equipped with an anti-erosion buffer between ignition electrode and the insulator arrangement, anti-erosion buffer is including setting up the isolation buffering protection chamber between ignition electrode's the ignition end, or ignition electrode's the ignition end and insulator arrangement's the corresponding end.
The insulation device comprises an inner insulation layer and an outer insulation layer which are arranged on the ignition electrode, and the isolation buffer protection cavity is formed by an inner space formed by a protruding end of the outer insulation layer which is longer than the end part of the corresponding end of the inner insulation layer.
The insulation device comprises a ceramic sleeve sleeved on the ignition electrode and a silica gel glass fiber sleeve sleeved on the ceramic sleeve.
The utility model discloses continuous casting cutting ignition is simple structure not only, reasonable, especially it has to the ignition end of ignition electrode, mainly be that the ignition end lean on corresponding insulating layer position to play fine isolation buffering formula scour protection and lose the effect. The ignition end of the ignition electrode which is always processed in a high-temperature environment during operation can work reliably and stably for a long time. Greatly improves the reliability of continuous casting cutting ignition and ensures the normal operation of steelmaking and continuous casting production.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
In order to facilitate a better understanding of the present invention, the present invention will be further described with reference to the following embodiments and drawings.
As shown in fig. 1. In this embodiment, its continuous casting cutting ignition includes ignition electrode, corresponding insulating device and scour protection and erosion buffer etc. and scour protection and erosion buffer is including setting up in the isolation buffering protection chamber of the ignition end of ignition electrode. The insulating device comprises an inner insulating layer 2 sleeved on the ignition electrode 1 and an outer insulating layer 3 sleeved on the inner insulating layer.
The ignition end of the outer insulating layer adjacent to the ignition electrode is longer than the ignition end of the inner insulating layer adjacent to the ignition electrode, and the isolation buffer protection cavity is formed by the interlayer space 4 formed by the extension (bulge) section 5 of the outer insulating layer longer than the inner insulating layer and the corresponding part of the ignition electrode. The inner insulating layer is composed of a ceramic sleeve, and the outer insulating layer is composed of a silica gel glass fiber sleeve.
When the ignition electrode operates, due to the heat conduction current gathering effect of the end face, close to the ignition end, of the insulating layer of the ignition electrode, the part, corresponding to the end face of the insulating layer, of the ignition electrode is extremely easy to erode, so that the ignition performance of the whole ignition electrode is gradually influenced and is damaged in an accelerated mode.
When the ignition electrode of the continuous casting cutting ignition device works, the isolation, the blocking and the protection of the peripheral wall (namely the extension section of the outer insulating layer) of the interlayer space are combined with the buffer cooperation effect of the interlayer space, so that the erosion influence of the heat radiation and the hot air flow of the high-temperature billet on the neck part area of the ignition end of the ignition electrode can be greatly reduced, the service life of the ignition electrode is greatly prolonged, and the ignition reliability is improved.
In another embodiment, the ignition end of the ignition electrode is provided with a threaded connection device, and an ignition head is arranged through the threaded connection device. The rest of the structure and the like may be similar to the above-described embodiments.
The above-described embodiments describe the technical principles of the present invention, and these descriptions are only for the purpose of explaining the principles of the present invention, and should not be interpreted as limiting the scope of the present invention in any way. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
Claims (3)
