Description of the Invention: [Technical Field of Invention] Field of the Invention The present invention relates to a refractory ceramic plug (embossing) for adjusting a metal frit flowing in an exit region of a metallurgical melting vessel such as a casting funnel ). [Prior Art 3] Such a plug is generally constructed as follows: it comprises a rod-shaped body having a first end and a second end, wherein the body is composed of at least one refractory material. The so-called rod shape must be understood by the technical meaning that the length of the body is much larger than its diameter/width. A bag-shaped opening (blind hole) extends from the first end of the body along the axial direction of the body toward the second end thereof, wherein the opening is as far as to reach a connection area having a bottom portion, and the connection area is Terminates in front of the second end of the body. A so-called feed region is provided at the first end of the body because a process gas is preferably an inert gas such as argon which is introduced into the opening of the plug. In order to introduce a gas flowing through the opening into a molten metal from a region of the second end of the body, at least one gas passage extends from the connecting region of the opening to a second end region of the body. Surface part. The gas passage has a cross-sectional area which is smaller than the cross-sectional area of the opening. The plug is placed in the gate (nozzle) region of the metallurgical melting vessel, and is oriented perpendicular to the first end at the top and the second end at the bottom adjacent to the gate. By raising and lowering the plug, a circular 201034772 passageway can be enlarged or reduced relative to the gate to adjust the amount of metal melt that is guided/flowed. Figure 1 shows this known arrangement in which the plug is shown with the numeral 10' and a corresponding gate is referenced 50. The lower (second) female 14 of the plug 10 is shown in a slightly elevated position, with an annular passage formed between the plug 1 and the wash, the melt S being able to The casting funnel shown flows through the passage into the gate 5 and from there into the downstream device.

In order to raise and lower the plug 1 , it is known to fasten a metal lever in the region of the opening 16 which is fixed to a corresponding lifting device with a portion protruding from the plug 16 toward the top. . As long as the top and bottom are mentioned within the scope of this application, this information is about the functional location of the plug. An untyped control valve has been used for a long time. However, it has been known that irregular flow conditions of far refining materials often occur during operation. This is due, among other things, to the transport and feeding of the gas. A closed plug is known from the patent DE 10 2005 029 033 , 4, in which a filling body extends through a portion of the opening - along the axial direction of the body, wherein there is a gas passage extending through the a filler body or between the filler body and the plug body along the axial direction of the filler body - and 201034772 is parallel to the central longitudinal axis of the closure plug or is spiraled, spiraled or rewinded or threaded, It fluidly connects the opening to the gas passage and delivers the gas to the surface of the second end of the plug. In this way, a means for adjusting the resistance of the gas flow is created. SUMMARY OF THE INVENTION One object of the present invention is to optimize a plug of the type described to achieve a controlled melt flow even if the plug is positioned differently relative to the gate. To solve the object, the present invention is based on the recognition that in Fig. 2 the flow rate (m3/h) is specifically directed to a device as in Fig. 1 and to a plug of one of the ordinates The gap between the two ends (nose end) and the corresponding gate is drawn on the abscissa. The dashed line schematically dictates the dependence in the absence of gas flow, and the solid line specializes the properties of the two features as they are fed. Although there is a linear relationship between the opening width and the amount of melted material in the absence of gas, there is a significant instability in the case where a process gas is fed. found out. Casting in this unstable region will fail and cause possible defects in the final product. Although the low opening width will have a linear relationship with the corresponding melt amount, instability will occur in the black background area. This unstable region will follow a few straight curves. The stream system shown to the left of the unstable point is named slow current, and the 201034772 stream system shown to the right of the unstable point is named as the bubbling stream. It is readily apparent that a continuous foundry can only operate optimally outside of the unstable regions shown in Figure 2. Therefore, only a specific change in the flow rate and flow rate curve of the melt flow can be achieved by changing the gap width. This is where the concept of the invention emerges. A refractory ceramic plug for adjusting a molten metal flow according to the present invention provides the following features: A rod-shaped body having a first end and a second end, the first end of the body having a pocket opening Extending from a feed region along the axial direction of the body to a connection region having a bottom; the connection region of the aperture has at least one gas passage extending as far as the surface of the body in a second end region a portion of the gas passage having a cross-sectional area that is smaller than the cross-sectional area of the opening; at least one section is provided along the opening, and a gas delivered to the connecting region by the feeding region is forcibly Guide the section; wherein the section provides an effective flow section that is smaller than the aperture; in the area between the bottom and a section adjacent to the bottom, there is a use A device that measures the pressure of the gas in the area will be placed or connected thereto. The above-mentioned section has a so-called limiter function as is known from the aforementioned DE 10 2005 029 033 B4 patent. When there is a lower gas pressure above this section, the reduced gas flow cross section in that section will cause the gas pressure and gas velocity to increase significantly and then decrease again because of an enlarged flow cross section. 201034772 When passing through the molten metal stream, different pressure conditions are developed in the melt depending on the width of the opening between the plug and the gate, because a different vacuum acts on the feed gas. . With the plug of the present invention, with the means for measuring the gas pressure in the connection region of the opening, the correct pressure of the gas leaving the plug can be determined at any time. Therefore, knowing the measured pressure data, the gap between the plug and the gate can be adjusted so that the casting operation can occur outside the unstable region shown in Fig. 2. This will be illustrated by an example: when casting, the modulation target is a bubble flow together. In this regard, the plugs and gates are arranged in a suitable manner relative to one another as a function of the amount and pressure of the feed gas. For example, if the casting output must be reduced during operation, or reduced due to metallurgical influences, such as a immersion tube clogging, which is attached to the gate after fluid technology, there is a risk. Entering this unstable region, and the amount of casting thereof increases, regardless of the gap width between the plug and the gate. This situation can be verified by pressure fluctuations in the connection area of the plug as too much gas will enter the reduced melt stream. This phenomenon can be used as an early detection of the changed flow pattern. By reducing the gas pressure in the connection zone, the plug will settle slightly in the direction of the gate, the gap will decrease and the melt flow will be reduced as desired. A means for measuring the pressure of the gas may be provided directly in the region of the opening, such as a pressure gauge, more preferably an electronic pressure measuring device capable of withstanding the temperature at which it is exposed (about 1500 to 1600 ° C). The transmission of the measured pressure value to an evaluation unit can be accomplished via a heat resistant cable, or wirelessly, as in the case of 201034772, by a radio. Because of the high temperatures and the small space available in the aperture area to provide the measuring device, a variant embodiment of the invention provides for a measurement channel to be placed between the bottom and the bottom adjacent to the bottom. In the area between the parts, it connects the connection area of the opening with a pressure measuring device. In this way, the actual pressure measuring device can also be arranged outside the plug, preferably in a region where the lower ambient temperature is exhibited, that is, for example, in the aforementioned lifting device for lifting the plug. In the area. In the measurement channel, the gas pressure in the connection region of the opening is revealed, so that it can be correctly detected. The measurement channel can be guided through the body by a connecting region of the opening at least in certain sections in a direction along the first end of the body. The measuring channel 嗣 is led out of the body, for example above the melt tank, and is passed to the pressure measuring device via a connecting line. The limiter segments can be embodied in different ways. One possibility is to locate the section in the opening itself. In this regard, the section can be formed by a filler body fixed in the opening, wherein at least one gas passage is kept open between the filling body and a corresponding wall of the opening. According to a variant embodiment, the section is formed by a filling body fixed in the opening, which extends through the entire section of the opening, wherein at least one gas passage passes through the filling body, and a gas The channel can be submerged to the quick-connect area of the opening. Another possibility to set the section is to provide a filler that extends through the entire section of the opening and divides the opening in the axial direction into two zones 201034772, and a channel that connects the opening One of the regions and the other region of the opening' has a cross section that is smaller than each of the regions of the opening. For example, the passageway will pass through the plug body such that the inlet and outlet are open in the wall of the opening. Each of the four gas passages has a cross section that is smaller than the opening. For example, the ratio is at least 1: 5 or at least 1: 10, but can be higher. Indeed, the opening may have a diameter of 15 to 30 mm, while the gas passage having a smaller cross section has a diameter of between 2 and 7 mm.

The path change completed in this process is detected by a measurement line π 在一 in an evaluation unit 46 and converted into a corresponding one. Gas pressure value. As stated, the values are based on (4) the steel worker's instructions to control or increase the flow rate of the steel material to enter the critical zone (Fig. 2). The embodiment of the figure substantially corresponds to the DE 1〇2〇() 5 〇29 〇33 B4 patent, but in this example the lower region 34 is very small and an electronic pressure measuring device 44 is located in the region. Between the segment (filler) 3〇 and the bottom, a measurement line 42" is conducted by the device 44, to conduct to an evaluation unit, wherein the measurement line 42" extends partially through the body 1 of the plug. Hey. Instead of transmitting these measurements via a cable, a wireless transfer wheel can also be provided, for example, with a radio. 201034772 It is apparent that the pressure gauge 44 and the evaluation unit 46 are placed in an area where a preferred low temperature is exhibited, i.e., outside the melt tank.
