Abstract
Description
Technical Field
[0001] This utility model relates to a width measuring device, and in particular to a device that can measure the width of the kerf in real time during the cutting of a continuously cast billet, belonging to the technical field of kerf width measuring equipment. Background Technology
[0002] In the continuous casting process, molten steel is poured into the crystallizer through a ladle and tundish to solidify and cool into continuously cast billets. These billets are then cut online to specific lengths according to rolling requirements. Most slabs and rectangular billets are cut online using flame cutting. To improve billet yield, the width of the cut kerf needs to be continuously measured online, and the flame system adjusted to maintain the cut kerf at the lower limit. Currently, daily production involves manually measuring the billet being cut using a ruler and template. However, the high temperature of the billet makes it difficult for workers to approach, and accurately measuring the kerf width under such intense heat is challenging, resulting in low measurement accuracy and high labor intensity. Therefore, a device is needed to assist workers in efficiently measuring the kerf width. Utility Model Content

Detailed Implementation
[0012] See Figure 1 and Figure 2 This utility model includes a horizontal guide section, a height adjustment section, an outer extension section, and a measuring section. The horizontal guide section allows the measuring section to be moved to various positions on the weld. The horizontal guide section is mounted on the continuously cast billet 1. The height adjustment section is mounted on the horizontal guide section. The function of the height adjustment section is to ensure that the round rod 12 can be smoothly inserted into the weld. The outer extension section is mounted on the height adjustment section. The function of the outer extension section is to ensure that the two round rods 12 can respectively press against the inner walls of the two welds, and thus the width of the weld can be determined by measuring the maximum distance between the two round rods. The measuring section is mounted on the outer extension section. The measuring section can measure the maximum distance between the two round rods, thereby determining the width of the weld.
[0013] The horizontal guide section includes a crossbeam 2, a fixed end plate 3, a sliding end plate 4, a first positioning plate 5, and a second positioning plate 6. One end of the crossbeam 2 is disposed on the side wall of the fixed end plate 3, and the sliding end plate 4 has a sliding hole through which the crossbeam 2 passes. The first positioning plate 5 is disposed on the side wall of the fixed end plate 3, and the second positioning plate 6 is disposed on the side wall of the sliding end plate 4. Both the first positioning plate 5 and the second positioning plate 6 press against the top surface of the continuous casting billet 1. The two end plates cooperate to clamp and fix the continuous casting billet. The positioning plates ensure that the centerline of the crossbeam 2 is parallel to the width direction of the continuous casting billet. Tightening the bolts on the sliding end plate 4 fixes its position, ensuring that the two end plates reliably clamp the continuous casting billet. The fixed end plate 3 and the sliding end plate 4 clamp the continuous casting billet 1 in the middle. The sliding end plate 4 has a threaded hole on its side wall, and the positioning bolt passes through the threaded hole of the sliding end plate 4 and presses against the side wall of the crossbeam 2.
[0014] The height adjustment section includes a plumb bob 7 and a plumb rod 8; a slide rail is provided on the side wall of the crossbeam 2 along its length; a groove is provided on the side wall of the plumb bob 7, and the plumb bob 7 is slidably mounted on the slide rail through the groove on the side wall; the plumb rod 8 is inserted into the hole at the top of the plumb bob 7; its vertical height can be adjusted by the vertical sliding of the plumb rod 8, and the vertical height of the round rod is finally adjusted to ensure that the round rod is smoothly inserted into the weld; a threaded hole is provided on the side wall of the plumb bob 7, and a bolt passes through the threaded hole on the side wall of the plumb bob 7 and presses against the side wall of the plumb rod 8; tightening the bolt on the side wall of the plumb bob 7 can fix the height of the plumb rod 8.
[0015] The outward-extending portion includes a long strip plate 9, a guide rod, a spring 10, and a horizontally moving vertical rod 11; one end of the long strip plate 9 is disposed on the top surface of the vertical rod 8; the length direction line of the long strip plate 9 is perpendicular to the length direction line of the crossbeam 2; a vertical strip-shaped hole is provided at the center of the long strip plate 9 along its length direction; a guide rod is provided between the side walls at both ends of the inner wall of the strip-shaped hole of the long strip plate 9 along its length direction; there are two horizontally moving vertical rods 11, and both of them pass through the strip-shaped hole of the long strip plate 9. A guide hole is provided on the side wall of the transverse vertical square rod 11, and a guide rod passes through the guide hole of the transverse vertical square rod 11; under the guidance of the guide rod, the two transverse vertical square rods 11 move closer or further apart from each other in the strip hole of the long strip plate 9; a spring 10 is provided between the ends of the transverse vertical square rod 11 and the strip hole of the long strip plate 9 that are closest in the longitudinal direction; the spring 10 gives the transverse vertical square rods 11 a force that moves them away from each other, ensuring that the two round rods can press tightly against the inner walls of both sides of the weld of the continuous casting billet.
[0016] The measuring part includes two round rods 12, a measuring scale 13, and a pointer 14. Two round rods 12 are respectively positioned on the bottom end faces of different horizontal moving vertical square rods 11, with each rod pressing against the inner walls of the two sides of the cut in the continuously cast billet 1. The measuring scale 13 is positioned on the top face of the horizontal moving vertical square rod 11, and the pointer 14 is positioned on the top face of the other horizontal moving vertical square rod 11, pointing to a graduation on the measuring scale 13. The distance between the pointer 14 and the zero mark of the measuring scale 13 is equal to the distance between the farthest points of the two round rods 12. Since the two round rods 12 press against the two side walls of the cut, the distance between the two points with the greatest distance between the two round rods 12 is the cut width. The distance between the two points with the greatest distance between the two round rods 12 can be determined using the measuring scale 13 and the support 14, thus providing the final cut width of the continuously cast billet.
[0017] Operating principle: After cutting a section of kerf, install this device; press the two positioning plates against the two ends of the top surface of the continuous casting billet, ensuring that the length direction of the crossbeam 2 is parallel to the width direction of the continuous casting billet; then fine-tune the position, pull the two round rods 12 closer, insert the round rods 12 into the kerf, and finally tighten the bolts on the sliding end plate 4 and the side wall of the vertical cylinder 7 to fix the position; at this time, the data pointed to by the pointer 14 on the measuring scale 13 is the width of the kerf at the position of the round rod. During the cutting operation, push the vertical cylinder 7 forward synchronously, push the round rod to the position where the width needs to be measured, and quickly measure the width, which greatly improves the accuracy and efficiency of the measurement. After the cutting is completed, loosen the bolts on the sliding end plate 4 and remove the device.
