Description

Technical Field

[0001] The invention relates to the technical field of metallurgy, and in particular to a device and method for discovering foreign matter blockage and abnormality in a skirt cover of a stepping furnace. Background Art

[0002] A walking-beam heating furnace (walking-beam furnace) is a heating furnace that moves the billet forward step by step by the rising, advancing, descending and retreating movements of the furnace bottom or water-cooled metal beam. It relies on a special stepping mechanism to move along a certain trajectory (usually a rectangular trajectory) to move the steel in the furnace forward step by step.

[0003] In the prior art, a water seal groove, upper and lower skirt covers, a scraper plate and a stepping beam are arranged at the bottom of a walking heating furnace. Under normal circumstances, the furnace bottom refractory material, the furnace bottom steel plate, the upper skirt cover, the lower skirt cover and the scraper plate are an integral body A, the walking beam and the water seal groove are an integral body B, and the columns realize up and down, front and back movement in the space of the skirt cover, and the two integral bodies move relative to each other. Once a larger hard object falls into the space, the foreign matter is stuck in the skirt cover, which will hinder the movement of the beam columns and destroy the relative movement between the water beam columns and the water skirt cover and the scraper plate. Normally, the steel plate of the upper skirt cover is welded to the steel plate of the furnace bottom, and the blockage will cause the steel plate of the upper skirt cover and the steel plate of the furnace bottom to eventually become unwelded, and the two move relative to each other, which will gradually destroy the furnace bottom refractory material, the furnace bottom loses heat insulation, the furnace bottom is separated from the skirt cover, the furnace chamber is penetrated by the outside, and the furnace is shut down. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned problems existing in the prior art and to provide a device and method for detecting foreign matter jams and abnormalities in the skirt cover of a stepping furnace. The device uses the horizontal changes caused by abnormal deformation of the equipment to trigger the device to start, form power, and generate an early warning signal. It can solve the problem of monitoring the deviation of the furnace head billet during the automatic loading of the billet in an end-in-end continuous heating furnace, and help inspection personnel to discover and intervene in time to avoid further deterioration.

[0005] To achieve the above object, on the one hand, the present invention provides a device for detecting foreign object jamming and abnormality in the skirt of a walking beam furnace, including an overall A and an overall B. The overall A includes a furnace bottom refractory, a furnace bottom steel plate, an upper skirt, a lower skirt, and a slag scraping plate. The overall B includes a walking beam and a water seal trough. An upper skirt welding steel plate is provided on the upper skirt. The device also includes an abnormal warning device for the skirt of the walking beam furnace. The abnormal warning device for the skirt of the walking beam furnace is located on one side of the upper skirt and is connected to the upper skirt welding steel plate. The abnormal warning device for the skirt of the walking beam furnace includes an upper housing and a lower housing installed in a matching manner with the upper housing. A chamber is formed between the upper housing and the lower housing. A support seat is provided in the chamber. A conduction ball is provided on the support seat. A first electrode and a second electrode are provided below the support seat. The first electrode and the second electrode form an open structure, and an insulating gap located below the conduction ball is provided between the bottoms of the first electrode and the second electrode. The first electrode and the second electrode are connected to a power supply;

[0006] When the work is normal, the conduction ball is located on the support seat; when a hard object enters the skirt space and jams, the relative movement between the walking beam column and the skirt is blocked, thereby squeezing the furnace bottom refractory, the furnace bottom steel plate, the upper skirt, the lower skirt, and the slag scraping plate, causing the welding between the furnace bottom steel plate and the upper skirt welding steel plate to be detached and relative movement to occur. The corresponding abnormal warning device for the skirt of the walking beam furnace tilts, the conduction ball rolls off the support seat, falls into the insulating gap, connects the circuit, and generates a power-on signal.

[0007] Preferably, the conduction ball is made of a conductive material.

[0008] Preferably, a support tray is provided on the support seat, and the conduction ball is located on the support tray.

[0009] Preferably, a horizontal adjustment mechanism is further provided in the chamber. The horizontal adjustment mechanism is used to adjust the conduction ball to be located at the center of the support tray.

[0010] Preferably, the horizontal adjustment mechanism includes a plurality of adjustment plates. One end of each adjustment plate close to the conduction ball is connected to each other, and the support tray is located on the adjustment plates.

[0011] Preferably, the support seat further includes a plurality of support seat side plates corresponding to the respective adjustment plates. One end of each adjustment plate away from the conduction ball is located on the corresponding support seat side plate.

[0012] Preferably, the horizontal adjustment mechanism further includes horizontal adjustment bolts corresponding to the respective adjustment plates. A bolt hole is provided on each support seat side plate, and the bolt hole is located below one end of the adjustment plate away from the conduction ball. A horizontal adjustment bolt is correspondingly provided in each bolt hole.

[0013] Preferably, the horizontal adjustment mechanism further includes a spirit level, which is located below the adjustment plate and coaxial with the support pallet.

[0014] Preferably, a limiting ring is provided on each support seat side plate, and the end of the adjustment plate away from the conduction ball and the support seat side plate are located within the limiting ring.

[0015] The second aspect of the present invention provides a method for detecting foreign object jamming and abnormality in the walking beam furnace skirt. The method for detecting foreign object jamming and abnormality in the walking beam furnace skirt is implemented in the above-mentioned device for detecting foreign object jamming and abnormality in the walking beam furnace skirt, and includes the following steps:

[0016] When the work is normal, the conduction ball is located on the support seat; when a hard object enters the skirt space and jams, the relative movement between the walking beam column and the skirt is blocked, thereby squeezing the bottom furnace refractory, the bottom furnace steel plate, the upper skirt, the lower skirt and the slag scraping plate, causing the welded steel plate of the bottom furnace steel plate and the upper skirt to become unsealed and have relative movement. The corresponding abnormal warning device of the walking beam furnace skirt tilts, the conduction ball rolls off the support seat, falls into the insulation gap, connects the circuit, and generates a power-on signal; it is confirmed whether there is foreign object jamming and abnormality in the walking beam furnace skirt by detecting whether a power-on signal is generated.

[0017] The present invention utilizes the horizontal change caused by abnormal deformation of the equipment to trigger the start of the device, form power-on, and generate a warning signal, which can solve the monitoring of the deviation of the billet at the furnace head during the automatic billet loading and unloading process of the end-fed and end-discharged continuous reheating furnace, help the inspection personnel to detect and intervene in time, and avoid further deterioration.

[0018] The device structure of the present invention is simple, which is convenient for timely detecting and warning the early situation of the bottom furnace and the upper skirt, facilitating the maintenance personnel to intervene in maintenance in time, and avoiding production stoppage caused by the deterioration of the situation.

[0036] Embodiment 1

[0037] As Figures 1-6 shown, the device for detecting foreign object jamming and abnormality in the walking beam furnace skirt includes overall A and overall B. Overall A includes the furnace bottom refractory 1, the furnace bottom steel plate 5, the upper skirt 6, the lower skirt 4, and the slag scraping plate 8. Overall B includes the walking beam 2 and the water seal tank 7. An upper skirt welding steel plate 10 is provided on the upper skirt 6. The device for detecting foreign object jamming and abnormality in the walking beam furnace skirt further includes a walking beam furnace skirt abnormality warning device 12. As Figure 4 shown, the walking beam furnace skirt abnormality warning device 12 is located on one side of the upper skirt 6 and is connected to the upper skirt welding steel plate 10. The schematic diagram of the walking beam furnace skirt abnormality warning device 12 is as Figure 6 shown. The walking beam furnace skirt abnormality warning device 12 includes an upper housing 121 and a lower housing 122 that is installed in a matching manner with the upper housing 121. A chamber is formed between the upper housing 121 and the lower housing 122. A support seat 123 is provided in the chamber. A conduction ball 124 is provided on the support seat 123. A first electrode 125 and a second electrode 126 are provided below the support seat 123. The first electrode 125 and the second electrode 126 form an open structure, and an insulating gap located below the conduction ball 124 is provided between the bottoms of the first electrode 125 and the second electrode 126. The first electrode 125 and the second electrode 126 are connected to a power supply;

[0038] When the work is normal, the conduction ball 124 is located on the support seat 123; when a hard object enters the skirt space and jams (as Figure 3As shown, the relative movement between the columns of the walking beam 2 and the skirt is blocked, thus squeezing the bottom refractory 1 of the furnace, the bottom steel plate 5 of the furnace, the upper skirt 6, the lower skirt 4, and the slag scraping plate 8, causing the welded steel plate 10 of the bottom steel plate 5 and the upper skirt to become unsealed (as Figure 5 shown), relative movement occurs, and the corresponding abnormal warning device 12 of the walking beam furnace skirt tilts, and the conduction ball 124 rolls off the support seat 123 and falls into the insulation gap, closing the circuit and generating an energization signal.

[0039] In the present invention, in order to ensure that the conduction ball 124 can close the circuit when it rolls into the insulation gap, the conduction ball 124 is made of a conductive material. Further, the material of the conduction ball 124 is pure copper; the size of the conduction ball 124 and the size of the insulation gap only need to ensure that the conduction ball 124 can close the circuit when it rolls into the insulation gap.

[0040] In a specific embodiment, the lower housing 122 has an arc-shaped structure, and the insulation gap is located at the bottom of the lower housing 122, facilitating the conduction ball 124 to roll into the insulation gap.

[0041] Preferably, the support seat 123 is used to support and place the conduction ball 124, and a support tray 127 is provided on the support seat 123, and the conduction ball 124 is located on the support tray 127.

[0042] Further, a horizontal adjustment mechanism 128 is also provided in the chamber. The horizontal adjustment mechanism 128 is used to adjust the conduction ball 124 so that it is located at the center of the support tray 127, that is, when the work is normal, it is ensured that the conduction ball 124 can be stably placed on the support tray 127 and will not roll.

[0043] Preferably, the horizontal adjustment mechanism 128 includes a plurality of adjustment plates 1281. One end of each adjustment plate 1281 close to the conduction ball 124 is connected to each other, and the support tray 127 is located on the adjustment plates 1281.

[0044] Preferably, the support seat 123 further includes a plurality of support seat side plates 1231 corresponding to the respective adjustment plates 1281. One end of each adjustment plate 1281 far from the conduction ball 124 is located on the corresponding support seat side plate 1231.

[0045] Further, the horizontal adjustment mechanism 128 further includes horizontal adjustment bolts 1282 corresponding to the respective adjustment plates 1281. A bolt hole is provided on each support seat side plate 1231, and the bolt hole is located below one end of the adjustment plate 1281 far from the conduction ball 124, and a horizontal adjustment bolt 1282 is correspondingly provided in each bolt hole.

[0046] In a specific embodiment, the horizontal adjustment mechanism includes three adjusting plates 1281 and three horizontal adjustment bolts 1282. One end of each adjusting plate 1281 close to the conduction ball 124 is connected to each other to form an integral structure. Correspondingly, there are also three support seat side plates 1231. Each support seat side plate 1231 is provided with a bolt hole, and each bolt hole is correspondingly provided with a horizontal adjustment bolt 1282.

[0047] Further, the horizontal adjustment mechanism 128 further includes a level 1283. The level 1283 is located below the adjusting plate 1281 (the level 1283 is connected to the adjusting plate 1281) and is coaxial with the support plate 127.

[0048] In a specific embodiment, each horizontal adjustment bolt 1282 is used to adjust the corresponding adjusting plate 1281. At the same time, the level 1283 is used to detect whether the adjusting plates 1281 are all in a horizontal state. For example, when the whole adjusting plate 1281 is not in a horizontal state, the horizontal adjustment bolt 1282 is adjusted to jack up or lower one end of the corresponding adjusting plate 1281 away from the conduction ball 124 through the bolt hole until the whole adjusting plate 1281 is in a horizontal state (the level 1283 shows horizontal), so that the conduction ball 124 is located at the center of the support plate 127.

[0049] Preferably, each support seat side plate 1231 is provided with a limiting ring 1232. One end of the adjusting plate 1281 away from the conduction ball 124 and the support seat side plate 1231 are located within the limiting ring 1232.

[0050] The above-mentioned limiting ring 1232 is used to limit the movement of the adjusting plate 1281 in the horizontal direction and guide the movement of the adjusting plate 1281 in the vertical direction.

[0051] In a specific embodiment, the walking beam furnace skirt abnormal warning device 12 further includes a clamping seat 129. The clamping seat 129 is welded to the outside of the upper skirt welding steel plate 10, and a clamping groove is provided at the bottom of the clamping seat 129, which is adapted to be clamped on the top of the upper shell 121; Further, a clamping plate is provided at the top of the upper shell 121, and the clamping groove at the bottom of the clamping seat 129 is adapted to be clamped on the clamping plate at the top of the upper shell 121.

[0052] In the present invention, the first electrode 125 and the second electrode 126 are respectively connected to the DC power supply through wires 13.

[0053] When a large hard object enters the skirt space and gets stuck, the relative movement between the column of the walking beam 2 and the skirt is blocked, thereby squeezing the bottom refractory 1, the bottom steel plate 5, the upper skirt 6, the lower skirt 4 and the slag scraping plate 8, causing the welded steel plate 10 of the bottom steel plate 5 and the upper skirt to become unsealed and undergo relative movement. The welded steel plate 10 of the upper skirt is deformed and cannot maintain a horizontal state. The corresponding abnormal warning device 12 of the walking beam skirt tilts, as Figures 7-8 shown. The horizontal state of the adjusting plate 1281 changes. When the deformation of the welded steel plate 10 of the upper skirt reaches a certain degree, the adjusting plate 1281 tilts greatly, and the conductive ball 124 will roll off the supporting plate 127 and fall into the insulation gap (generally, when it tilts about 10°, the conductive ball 124 will start to roll).

[0054] Furthermore, a signal lamp can be connected in series or an HMI system can be connected to the circuit composed of the first electrode 125, the second electrode 126, the wire 13 and the DC power supply; when a signal lamp is connected in series to the circuit, when the operation is normal, the conductive ball 124 rests statically on the supporting plate 127. Due to the existence of the insulation gap, the circuit is not connected, and there is no power-on signal at this time, so the signal lamp does not light up; when a hard object enters the skirt space and gets stuck, the conductive ball 124 rolls off the supporting plate 127 and falls into the insulation gap, the circuit is connected, a power-on signal is generated, and the signal lamp lights up; when the HMI system is connected to the circuit, when the operation is normal, the conductive ball 124 rests statically on the supporting plate 127. Due to the existence of the insulation gap, the circuit is not connected, and there is no power-on signal at this time, and there is no alarm on the HMI; when a hard object enters the skirt space and gets stuck, the conductive ball 124 rolls off the supporting plate 127 and falls into the insulation gap, the circuit is connected, a power-on signal is generated, and the power-on signal is transmitted to the PLC through the sensor, and an alarm prompt appears on the HMI; the above operations can be used to detect whether a power-on signal is generated in the circuit, and further confirm whether there is foreign object blockage and abnormality in the walking beam skirt of the walking beam furnace.

[0055] In a specific embodiment, in order to prevent the conductive ball 124 from running around during the installation of the abnormal warning device 12 of the walking beam skirt, two symmetrically arranged threaded holes 1211 are also provided on the upper housing 121, and these two threaded holes 1211 are respectively located on both sides of the conductive ball 124. During the installation of the abnormal warning device 12 of the walking beam skirt, as Figures 9-11As shown in the figure, first weld the card seat 129 to the outside of the upper skirt cover welding steel plate 10, then install the support seat 123, support plate 127, limit ring 1232, horizontal adjustment mechanism 128 and conduction ball 124 inside the upper housing 121. Then, screw a fixing screw 14 into each threaded hole 1211 respectively, make the two fixing screws 14 contact the conduction ball 124 and fix the conduction ball 124. Then, clamp the clamping plate at the top of the upper housing 121 through the card slot at the bottom of the card seat 129, and adjust the conduction ball 124 through the horizontal adjustment mechanism 128 to make it located at the center of the support plate 127 (the spirit level 1283 shows horizontal). Then, install the lower housing 122, the first electrode 125 and the second electrode 126. Then, rotate the fixing screw 14 to loosen the conduction ball 124 and make it freely rest on the support plate 127. Finally, connect the first electrode 125 and the second electrode 126 to the DC power supply through wires 13 respectively.

[0056] Embodiment 2

[0057] A method for discovering foreign object jamming and abnormality in the skirt cover of a walking beam furnace. This method for discovering foreign object jamming and abnormality in the skirt cover of a walking beam furnace is implemented in the device for discovering foreign object jamming and abnormality in the skirt cover of a walking beam furnace in Embodiment 1, and includes the following steps:

[0058] When the work is normal, the conduction ball 124 rests statically on the support plate 127. Due to the existence of the insulation gap, the circuit is not connected and there is no power-on signal at this time. When a hard object enters the skirt cover space and jams, the relative movement between the column of the walking beam 2 and the skirt cover is blocked, thereby squeezing the furnace bottom refractory 1, furnace bottom steel plate 5, upper skirt cover 6, lower skirt cover 4 and slag scraping plate 8, causing the furnace bottom steel plate 5 and the upper skirt cover welding steel plate 10 to become unsoldered and have relative movement. The corresponding abnormal warning device 12 of the walking beam furnace skirt cover tilts, the conduction ball 124 rolls off the support plate 127 and falls into the insulation gap, connecting the circuit and generating a power-on signal; it is confirmed whether there is foreign object jamming and abnormality in the walking beam furnace skirt cover by detecting whether a power-on signal is generated.

[0059] The device of the present invention has a simple structure, which is convenient for timely detecting and warning the early situation of the furnace bottom and the upper skirt cover, facilitating maintenance personnel to intervene in maintenance in time, and avoiding production stoppage caused by the deterioration of the situation.

The corresponding abnormal warning device (12) of the walking beam furnace skirt tilts, the conduction ball (124) rolls off the support seat (123), falls into the insulation gap, closes the circuit, and generates a power-on signal; it is confirmed whether there is foreign object jamming and abnormality in the walking beam furnace skirt by detecting whether a power-on signal is generated.
