Description

Technical Field

[0001] The utility model relates to the technical field of equipment related to the drop measurement of a slag skimmer, and more specifically, particularly relates to a novel drop measurement system for a slag skimmer. Background Art

[0002] The iron outlet and slag outlet of the blast furnace ironmaking skimmer need to maintain a certain height difference. During production and use, the height difference will change due to the different erosion rates of liquid iron and liquid slag on refractory materials. In order to prevent the function of the skimmer from being affected by the height difference change, the height difference needs to be measured frequently to provide a basis for skimmer maintenance.

[0003] like Figure 1 As shown, Figure 1 The figure is a schematic diagram of the relevant measuring device when measuring the height difference of the blast furnace ironmaking slag skimmer by the traditional method.

[0004] The traditional method for measuring the drop of a slag skimmer is as follows: first, remove the dust cover 5 and the iron ditch cover 6 of the slag skimmer above the slag skimmer to fully expose the slag skimmer; then place a cross bar 3 on the iron outlet 1 of the slag skimmer, insert the straight measuring rod 4 into the deepest part of the iron outlet 1 of the slag skimmer, make the straight measuring rod 4 contact with the cross bar 3, and mark the intersection of the straight measuring rod 4 and the cross bar 3; after the first marking is completed, move the cross bar 3 to the slag outlet 2 of the slag skimmer, use the same end of the straight measuring rod 4 inserted into the iron outlet 1 of the slag skimmer, insert it into the deepest part of the slag outlet 2 of the slag skimmer, make the straight measuring rod 4 contact with the cross bar 3, and mark the intersection of the straight measuring rod 4 and the cross bar 3; finally, measure the distance between the two marks on the straight measuring rod 4 to obtain the drop value of the slag skimmer.

[0005] During the error measurement process, the dust cover 5 of the slag skimmer and the iron ditch cover 6 need to be removed, which results in the traditional drop measurement method requiring the measurement personnel to measure in a high temperature environment, and the working environment is poor and dangerous. In addition, the traditional measurement method requires at least two people to operate at the same time to complete, which wastes human resources. In addition, due to the influence of the working environment, the measurement operation will be completed in a short time, resulting in inaccurate measurement data and delaying the maintenance of the slag skimmer, causing various production accidents during the blast furnace iron-making process, and even safety accidents in serious cases.

For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0036] Please refer to Figure 2 ,in, Figure 2 This is a schematic diagram of the relevant measuring device when a new skimmer drop measurement method is adopted in an embodiment of the utility model.

[0037] The utility model provides a novel skimmer drop measurement system, which has the following specific structure, including: a skimmer dust cover 5 for covering the skimmer, wherein measuring holes are arranged on the skimmer dust cover 5 at positions corresponding to the skimmer iron outlet 1 and the skimmer slag outlet 2; a measuring rod 4 for drop measurement, wherein one end of the measuring rod 4 is a measuring end, and the measuring end can pass through the measuring hole and be inserted into the bottom of the skimmer iron outlet 1 and the skimmer slag outlet 2; and a laser level 7 which can emit a horizontal laser beam for constructing a horizontal laser measurement plane.

[0038] The skimmer is provided with two vertical channels, one for the outflow of molten iron, provided with a skimmer tapping port 1, and the other for the output of slag, provided with a skimmer tapping port 2. In order to improve the safety in the field and ensure the quality of molten iron, the utility model is provided with a skimmer dust cover 5 above the skimmer, which is used to completely cover the skimmer tapping port 1 and the skimmer tapping port 2. The bottom of the skimmer tapping port 1 and the skimmer tapping port 2 is a downwardly concave curved surface structure.

[0039] The skimmer dust hood 5 provided by the utility model is a rectangular hood structure, the top surface of the skimmer dust hood 5 is a horizontal plane, and in the vertical direction, measuring holes are provided on the skimmer dust hood 5 corresponding to the lowest point of the skimmer iron outlet 1 and the lowest point of the skimmer slag outlet 2, and the measuring rod 4 only needs to be kept in a vertical state and inserted into the measuring hole.

[0040] Furthermore, the utility model can also provide a vertical sleeve on the outer side surface of the skimmer dust cover 5 and corresponding to the measuring hole. The inner hole diameter of the vertical sleeve is slightly larger than the diameter of the measuring rod 4 (the inner hole diameter of the vertical sleeve is 2mm-5mm larger than the diameter of the measuring rod 4). This can ensure that the measuring rod 4 can pass through the vertical sleeve and be inserted into the skimmer iron outlet 1 or the skimmer slag outlet 2, and can also ensure that the measuring rod 4 remains in a vertical state without manual support through the vertical sleeve, thereby freeing up human resources and only one person is needed to complete the drop measurement.

[0041] In the present invention, the measuring rod 4 can be provided with one or more. When one is provided, the measuring rod 4 needs to be inserted into the slag skimmer tapping port 1 or the slag skimmer tapping port 2 respectively, and marking is performed on the same measuring rod 4. When multiple measuring rods are provided, the present invention can use two of them to be inserted into the slag skimmer tapping port 1 or the slag skimmer tapping port 2 respectively and marked respectively, and then take out the two measuring rods 4 to compare the marked points.

[0042] The dust collecting cover 5 of the skimmer is a rectangular cover structure, and the top surface of the dust collecting cover 5 of the skimmer is a horizontal plane, so that the laser level 7 can be placed on the top surface of the dust collecting cover 5 of the skimmer to measure the height difference.

[0043] Specifically, the laser level 7 includes a horizontal fine-tuning bracket, a mounting platform is provided on the horizontal fine-tuning bracket, and a main device can be fine-tuned in circumferential rotation on the mounting platform. Further, the horizontal fine-tuning bracket includes fine-tuning legs, and there are three fine-tuning legs, which are arranged at equal intervals around the rotation center of the main device, and the three fine-tuning legs are arranged to be tilted outward relative to the rotation center of the main device and have the same tilt angle.

[0044] For the measuring rod 4, the measuring rod 4 adopts an equal-diameter long straight rod structure design. The measuring rod 4 is made of high-temperature resistant metal material, and the surface of the measuring rod 4 is a smooth polished structure (mirror treatment), which is used for marking and wiping with a marker pen. The polished structure can easily wipe the markings of the marker pen clean, which is convenient for the next measurement.

[0045] It can be seen from the above structural design that the utility model provides a new type of skimmer drop measurement system. In the utility model, the new type of skimmer drop measurement system includes: a skimmer dust cover 5 for covering the skimmer, and measuring holes are provided on the skimmer dust cover 5 corresponding to the positions of the skimmer iron outlet 1 and the skimmer slag outlet 2; a measuring rod 4 for drop measurement, one end of the measuring rod 4 is the measuring end, and the measuring end can be inserted through the measuring hole to the bottom of the skimmer iron outlet 1 and the skimmer slag outlet 2; a laser level 7 that can emit a horizontal laser beam to construct a horizontal laser measurement plane.

[0046] In actual use, the dust cover 5 of the skimmer will always cover the top of the skimmer without removal, which not only reduces the workload of the drop measurement, but also enables the measurement personnel to operate at close range and improve the measurement accuracy. In addition, the utility model also uses the horizontal laser surface emitted by the laser level 7 as a measurement reference, so that the measurement data connection is closer and more reliable. Since the measurement reference standard remains unchanged (once the laser level 7 is set, the laser level 7 will no longer move during the entire drop measurement process), therefore, one operator can complete the measurement work. The use of the utility model can make drop measurement safer and more accurate.

[0047] In the present invention, the method for measuring the drop using the novel skimmer drop measurement system is as follows, comprising the steps of:

[0048] Step 1: Set up a laser level 7 and construct a horizontal laser measurement plane using the laser level 7.

[0049] The laser level 7 uses an existing device that can emit a horizontal laser to construct a horizontal laser measurement plane. Within the coverage range of the laser measurement plane, a laser irradiation point can be formed as long as the height is higher than the height of the laser measurement plane. It should be noted that in step 1, the laser range emitted by the laser level 7 must cover the entire area where the ironworks is located.

[0050] The utility model limits the setting height of the laser level 7 in step one: the setting height of the laser level 7 is higher than the height of the skimmer dust hood 5 (so that the laser measurement plane will not be irradiated on the dust hood 5, avoiding the dust hood 5 from affecting the measurement), and lower than the highest height marked by the surveyor on the measuring rod 4 (so that it is convenient for the surveyor to observe the laser irradiation point and mark the laser irradiation point).

[0051] Step 2: Keep the measuring rod 4 in a vertical state and insert it into the dust removal cover 5 of the slag skimmer corresponding to the iron outlet 1 and the slag outlet 2 of the slag skimmer.

[0052] After the laser level 7 is set up (the laser level 7 not only has requirements on height, but also should ensure that the laser measurement plane formed by it remains horizontal), the surveyor needs to use the measuring rod 4 for measurement. Specifically, the measuring rod 4 is a straight round rod structure with equal diameter.

[0053] In order to enable the measuring rod 4 to be inserted into the dust hood 5, the utility model needs to open a measuring hole on the dust hood 5. Specifically, a measuring hole is set on the skimmer dust hood 5 and corresponds to the positions of the skimmer iron outlet 1 and the skimmer slag outlet 2. Further, the measuring hole corresponds to the lowest point of the skimmer iron outlet 1 and the skimmer slag outlet 2, that is, in the vertical direction, the measuring hole corresponds to the lowest point of the skimmer iron outlet 1 and the skimmer slag outlet 2.

[0054] In the present invention, the shape of the opening of the measuring hole is consistent with the cross-sectional shape of the measuring rod 4, and the size of the opening of the measuring hole is slightly larger than the cross-sectional size of the measuring rod 4, so that the measuring rod 4 can be smoothly inserted from the measuring hole into the dust cover 5. In addition, the present invention can also be provided with a measuring device for measuring the verticality of the measuring rod 4 in a vertical state, such as a plumb bob can be hung, so that the measuring error caused by the tilt of the measuring rod 4 can be avoided.

[0055] In step 2, the utility model provides a small cover on the outside of the skimmer dust cover 5 to close the measuring hole.

[0056] In step 2, the present invention uses the same measuring rod 4 to measure the drop, one end of the measuring rod 4 is the measuring end, and the measuring end is inserted into the skimmer dust cover 5 for measurement. In another embodiment of the present invention, the present invention can use two identical measuring rods 4 to measure the drop.

[0057] Step 3: Mark the measuring rod 4 at the location illuminated by the laser measuring plane.

[0058] Step 4: Take out the measuring rod 4 and calculate the length difference of the marked point to obtain the skimmer drop value.

[0059] Based on the above-mentioned new skimmer drop measurement method, the utility model also provides a new skimmer drop measurement system, specifically, the new skimmer drop measurement system includes: a skimmer dust cover 5 for covering the skimmer, and measuring holes are provided on the skimmer dust cover 5 corresponding to the positions of the skimmer iron outlet 1 and the skimmer slag outlet 2; a measuring rod 4 for drop measurement, one end of the measuring rod 4 is the measuring end, and the measuring end can pass through the measuring hole and be inserted into the bottom of the skimmer iron outlet 1 and the skimmer slag outlet 2; a laser level 7 that can emit a horizontal laser beam to construct a horizontal laser measurement plane; the measuring rod 4 is kept in a vertical state and inserted into the skimmer dust cover 5 corresponding to the skimmer iron outlet 1 and the skimmer slag outlet 2, and marks are made on the measuring rod 4 and at the irradiation point of the laser measurement plane, and the skimmer drop value is obtained by calculating the length difference of the measuring rod 4 and then the marked point.

[0060] The utility model provides a novel skimmer drop measurement method. In the utility model, the skimmer drop measurement method uses the horizontal laser plane emitted by the laser level 7 as a reference datum plane to measure the drop. The utility model does not need to move the dust removal facilities of the skimmer when it is put into use. It only needs to open a small hole in the dust cover 5 corresponding to the slag outlet 2 and the iron outlet of the skimmer as a measuring hole to meet the insertion of the measuring rod 4. Furthermore, different forms of movable small covers can be installed outside the measuring hole of the dust cover 5. When not measuring, the small cover can be covered to block the measuring hole, and the measuring hole can be opened when measuring. The utility model is provided with a small cover and will not have any impact on the dust removal facilities.

[0061] Regarding the setting of the laser level 7, the laser level 7 can be set up at a height higher than the dust hood 5 of the slag skimmer, and lower than the highest height range where the surveyor stands on the dust hood 5 of the slag skimmer and raises his hand to mark on the measuring rod 4. The setting method of the laser level 7 can ensure that the laser can radiate to any point in the plane of the dust hood 5 of the slag skimmer. The specific setting position of the laser level 7 can be any place that meets the above conditions, such as above the dust hood 5, on the swinging spout reducer in front of the furnace, and on the stair corridor near the iron-making yard.

[0062] During the measurement process, the surveyor can use the same end of a straight measuring rod 4 to vertically insert into two measuring holes (the utility model is provided with two measuring holes, one measuring hole corresponds to the slag outlet, and the other measuring hole corresponds to the iron outlet), and mark the laser irradiation position on the measuring rod 4. After obtaining the mark, the skimmer drop value can be obtained by measuring the distance between the two marks. The utility model can also use two different straight measuring rods 4 to vertically insert into the two small holes at the same time, and mark the laser irradiation position on the measuring rod 4. The skimmer drop value can be obtained by measuring the length difference between the insertion ends of the two straight measuring rods 4. In a specific embodiment of the utility model, two measuring rods 4 are used, and one end of the measuring rod 4 is the insertion end. When measuring, the insertion end is inserted into the measuring hole and is against the lowest point of the slag outlet or the iron outlet. After marking, take out the measuring rod 4, align the insertion ends, and measure the distance between the marked points of the two measuring rods 4 to obtain the skimmer drop value. The application of the utility model does not require the removal of the dust cover 5, and the negative pressure dust removal facility of the skimmer is utilized to improve the measurement environment, so that the measurement operator can work at a close distance, thereby improving the measurement accuracy.

[0063] As can be seen from the above, the utility model provides a new skimmer drop measurement method, which includes: step one, setting a laser level 7, and constructing a horizontal laser measurement plane through the laser level 7; step two, keeping the measuring rod 4 in a vertical state and inserting it into the skimmer dust cover 5 corresponding to the skimmer iron outlet 1 and the skimmer slag outlet 2; step three, marking the measuring rod 4 and the irradiation point of the laser measurement plane; step four, taking out the measuring rod 4 and then calculating the length difference of the marked point to obtain the skimmer drop value. Based on this measurement method, the utility model also provides a new skimmer drop measurement system. In the utility model, through the design of the above-mentioned operation method, in the skimmer drop measurement method provided by the utility model, the utility model does not need to remove the dust cover 5, and improves the measurement environment by using the skimmer negative pressure dust removal facility, so that the measurement personnel can work at close range (very close to the skimmer), thereby improving the measurement accuracy. At the same time, the horizontal laser surface of the laser level 7 is used as a measurement reference to make the measurement data connection more closely and reliably. By adopting the measuring method provided by the utility model, one operator can complete the measuring work, and due to the assistance of dust removal equipment and the reference of the horizontal laser plane, the working environment is comprehensively improved and the measuring data is more accurate and reliable.

[0064] The utility model first enables the laser radiation range of the laser level 7 to irradiate the area of ​​the skimmer dust hood 5 (that is, the laser coverage area of ​​the laser level 7 can cover the area where the skimmer dust hood 5 is located like a hood). At the same time, the setting height of the laser level 7 is higher than the height of the skimmer dust hood 5, and lower than the highest height of a person standing on the skimmer dust hood 5 and raising his hand to mark on the straight measuring rod 4. The above setting requirements for the laser level 7 enable the laser emitted by the laser level 7 to irradiate the measuring rod 4. Set up the laser level 7, then adjust the horizontal state of the laser level 7, turn on the laser level 7, and at this time, a horizontal laser beam will appear on any object around the entire iron-making yard. During the entire measurement process, always keep the laser level 7 in an open and stationary state.

[0065] The utility model provides two measuring methods.

[0066] Method 1: Insert the straight measuring rod 4 into the measuring hole of the skimmer dust cover 5 just above the skimmer iron outlet 1. The surveyor stands on the skimmer dust cover 5 and can repeatedly adjust the posture of the straight measuring rod 4 to make it in a vertical state; then mark the bright light on the straight measuring rod 4 with the horizontal laser emitted by the laser level 7 and pull out the straight measuring rod 4; then insert the same end (measuring end) of the straight measuring rod 4 into the small hole of the skimmer dust cover 5 just above the skimmer slag outlet 2 again, and can repeatedly adjust the posture of the straight measuring rod 4 to make it in a vertical state; then mark the bright light on the straight measuring rod 4 with the horizontal laser emitted by the laser level 7; finally, measure the distance between the two marks to obtain the skimmer drop value.

[0067] Method 2: Two straight measuring rods 4 can be used, and they can be inserted into the small holes of the skimmer dust cover 5 just above the skimmer iron outlet 1 and the skimmer slag outlet 2 respectively; the posture of the straight measuring rods 4 can be repeatedly adjusted to make it in a vertical state; then the horizontal laser emitted by the laser level 7 can be used to mark the bright spots on the two straight measuring rods 4, and the straight measuring rods 4 can be pulled out. The length difference between the inserted ends of the two straight measuring rods 4 can be measured to obtain the skimmer drop value.

[0068] After the measurement is completed, if a small cover is installed on the small hole of the skimmer dust cover 5, cover the small cover to restore the original appearance, and finally close the laser level 7 to complete all operations.

[0069] The advantages of the utility model are: utilizing the negative pressure working characteristics of the dust removal facility greatly improves the measurement environment, and the measurement personnel can make repeated adjustments to improve the measurement accuracy without being restricted by time. Secondly, due to the horizontal laser characteristics of the laser level 7, it can ensure that the measurement reference surface is reliably locked on the same plane, so that the reliability of the measurement result is greatly improved. Finally, since the marking position is invisibly raised, and the small hole on the dust removal cover 5 of the skimmer itself acts as a support rod, the measurement work only needs one person to complete, which not only saves effort, but also achieves the purpose of saving manpower.

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
