    A sublance for use in performing measurements and/or taking samples in a metallurgical furnace, which has an elongate outer body 3,11 having at its upper end suspension means 4, and at its lower end 12 a probe 10. Near the upper end, the body is divided by a rotational coupling 8,9 into two parts, the lower part 11 being relatively rotatable about the longitudinal axis, so that bending distortion of the lance in use can be reversed by turning the lance through 180°. To achieve a simple construction, the inner and intermediate tubes 15,14 within the lance are not rotationally divided but extend within the rotatable outer part 11 to the lower end 12 where the inner tube 15 is rotationally coupled to the probe.

    专利说明:

    11 The invention relates to a device used for measuring and / or sampling in a metallurgical furnace. Such a device is mainly used in a metallurgical furnace, where there is a main pipe for supplying oxygen, in which the device, having a probe at its lower end, is immersed in a bath of hot metal and removed from it. The proposed device is described by the example of its use in an envelope for producing steel, in which LIQUID cast iron is converted to steel by blowing oxygen from the top of the main pipe. It is also possible to use the invention in metallurgical furnaces with a different type of metallurgical process. The purpose of the invention is to simplify the scientific research institute of manufacture and repair of the device, as well as to expand its technological capabilities. FIG. 1 shows a schematic representation of the device; in figure 2, the same, after purging oxygen; in fig. 3 - the same, longitudinal section; in fig. 4 - ancillary tool (key) used dp turning the device. FIG. T and 2 show the main pipeline 1, which is used to blow oxygen into the molten metal bath 2. The sampling device 3 is shown in its lowest position, usually located parallel to the main pipeline 1 and fitted with flanges 4 and a probe 5 installed on its lower end, immersed in a metal bath. The flanges 4 located at the upper end of the device 3 serve to suspend the device 3 in a drive system (not shown) used for its vertical movement. The inlet 6 and outlet 7 for the cooling liquid are connected near the upper end of the device 3, so that the device is cooled to the mounting means of the probe 5 with a flow of coolant in it. Near the upper end of the device 3, its outer tubular element and the body are divided, and its two parts are connected by a coupling formed by two connecting parts 8 and 9. The connecting parts 8, 9 can rotate relative to each other around the vertical axis 0 and provide a gasket for prevent leakage of the cooler. The outer tubular element has a mounting element 10 and a lower part 11, which can rotate around a longitudinal axis of the lance relative to the suspension flanges 4. At the lower end of the device 3 there is a stopper 12 fastened to the rotating part 11 of the outer element provided with an additional tube 13. Inside the outer element, intermediate 14 and 15 internal pipes 15 are mounted to the rotating lower part 11, which are fixed to the upper end of the device 3 (Fig. 3 ). Thus, pipes 14, 15 form with the outer pipe two concentric annular spaces for the descending and ascending flow of coolant, connected respectively to the inlet and outlet connections 6, 7, which are located on the non-rotating upper part of the outer pipe. The lower end of the intermediate pipe 14 is free, allowing free communication of annular spaces at this end of the device. The space in the inner tube 15 can be used for the cable connecting to the probe 5 mounted on the lower end of the device. The upward directed tube 13 is connected to the tubular lower extension 16 of the inner pipe 15. The pipe 13 rotates in the extension 16 and is sealed against it with two liquid-impermeable sealing rings 17. The mounting element 10 for the probe 5 is attached to the plug -12 (Fig. 2). Thus, the stopper 12 holds the probe 5 fixedly on the rotating part 11 and forms a rotating connection of the probe with the inner tube 15 at the lower end of the device 3. The ring 18 rotates around part 8, has bearings sealed with screws 19 and moving in a groove in part 8 The connecting parts 8 and 9 are sealed against each other by a gasket 20 to prevent the liquid from passing. The connecting part 9 is fastened to the ring 18 with screws 21. The round head of the screws 21 also serves as a grip when using to rotate part of the pipe 11 relative to the connecting part 8. The key intended for this purpose consists of the handle 22 and the semicircular part 23 notches 24 (Fig. 4). The cutouts 24 correspond to the heads of the screws 21. The mounting element 10 of the probe 5 is provided with a contact block 25. The device operates as follows. FIG. 1, solid lines indicate the position of the device before blowing oxygen through the metal bath. The device at this time is straight and vertical. During purging, the device is heated on one side more than on the other in such a way that it bends from to the side of the purge site and reaches the position shown by dotted lines. Next, the device moves upward, and in the raised position, the connecting part 9 is rotated 180 relative to the connecting part 8 so that the device is again moved to a lowered position, in which it occupies the position shown in solid lines in FIG. 2. As the metal is blown again, the device bends in lx, at 404 the reverse side until it becomes straight again, as shown by the dotted lines in FIG. 2. After the completion of the second .ph. Of the purge and the corresponding raising and lowering of the device, there is no need for mutual rotation of the connecting parts 8 and 9, since the device now has such a position and shape that it had in its original position. (Fig. 1). Only after further use of the device will it bend again, and the two parts of the outer part of the tube must be rotated mutually. If this order is observed, it is sufficient if the lower part of the outer tube of the device is rotated 180 ° after every two uses. The rotation of the outer pipe part 11 therefore does not cause rotation of the intermediate and inner pipes 14, 15, which are not separated with respect to the rotation. When the outer pipe 11 is deformed (Figs. 1 and 2) and when it rotates 180, the inner pipe 15 is held back to maintain its concentration in the outer pipe by joints 13, 16. The intermediate pipe 14 is also held back and therefore may lose its concentration, but this does not adversely affect the flow of the cooler.
