Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking and continuous casting, in particular to a tool for quickly measuring the de-squareness of a square billet. Background Art

[0002] De-squareing of small square billets is a common quality defect in continuous billet casting. It is caused by uneven cooling of molten steel in the crystallizer and uneven thickness of the primary billet shell, and is also affected by a combination of other factors. De-squareing of square billets not only affects the bite of the rolling mill in the next rolling process, causing rolling difficulties, but is also often accompanied by longitudinal cracks at the corners and on the face, and in severe cases, steel leakage accidents may occur. There are many quality inspection items for continuous casting billets. Among them, whether the de-squareing of continuous casting billets exceeds the standard is a daily inspection content. The difference in the length of their diagonals must meet industry standards. Currently, the inspection tools are rulers and tape measures. The difference in their diagonal lengths is calculated by measuring the side length of the continuous casting billets, which is relatively cumbersome. At the same time, there are certain limitations in the measurement due to factors such as the stacking, temperature, and distance of the continuous casting billets. It is impossible to quickly and accurately measure the de-squareing amount of the continuous casting billets. Utility Model Content

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a tool for quickly and accurately measuring the squareness of a billet. The squareness of a billet can be quickly and accurately obtained by directly measuring the lengths of two diagonals of the billet.

[0004] According to the utility model, a tool for quickly measuring the de-squareness of a square billet is proposed, which includes a fixing part, a measuring part and a hand-held part. The fixing part is a cylinder, and a groove is vertically provided on the cylindrical surface of the cylinder; the measuring part includes a flat plate and a scale, the scale is connected to the bottom of the flat plate, and the flat plate is connected to the fixing part; one end of the hand-held part is connected to a slider, and the slider is connected to the flat plate of the measuring part.

[0005] Preferably, the flat panel is provided with a slide rail, and the handheld part can move left and right within the slide rail.

[0006] Preferably, the hand-held portion is a telescopic rod.

[0007] Preferably, the handle is rotatably connected to the slider.

[0008] Preferably, a pointer is connected to the slider.

[0009] Preferably, the scale is a rectangular sheet.

[0010] Preferably, the flat plate has a protrusion, which is slidably connected to the groove, so that the flat plate can slide up and down in the fixing portion.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] First, the tool is easy to operate and can directly measure the diagonal length of the continuous casting billet, allowing operators to quickly determine the amount of de-squareness and determine whether the shape of the continuous casting billet meets quality control requirements.

[0013] Second, the fixed part of the tool is provided with a groove, which can fit the corner of the continuous casting billet to prevent sliding. The flat plate can slide up and down in the fixed part, so that the scale contacts the surface of the continuous casting billet, and the reading is more accurate.

[0014] Third, the handheld part of this tool can drive the pointer to move left and right on the measuring part, making it easy to read; the telescopic rod of the handheld part is rotatably connected to the slider, and the angle can be adjusted according to different measurement environments, which is easy to operate. It also has a telescopic function to achieve long-distance measurement of the diagonal length of continuous casting square billets. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In the description of the present invention, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0022] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connected," "fixed," etc., should be understood broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical signal connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0023] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this utility model are for illustrative purposes only and do not represent the only embodiment.

[0024] Reference Figures 1-4 , Figure 1 A schematic structural diagram of a tool for quickly measuring the de-squareness of a square billet in one embodiment of the present invention is shown. The tool includes a fixing part 1, a measuring part 2 and a hand-held part 5. The fixing part 1 is a cylinder with a groove 9 provided on one side. The measuring part 2 includes a flat plate 3 and a scale 4. The flat plate 3 has a protrusion 11. The scale 4 is a rectangular thin sheet and is provided on the bottom surface of the flat plate. The fixing part 1 and the measuring part 2 are slidably connected by the groove 9 and the protrusion 11.

[0025] A slide rail 10 is provided on the flat plate 3, one end of the handheld part 5 is connected to the slider 7, the slider 7 is connected to the slide rail 10 of the measuring part 2, and a pointer 8 is connected to the slider. The left and right movement of the handheld part 5 can drive the pointer 8 to move on the scale 4.

[0026] During the measurement process, first align and clamp the groove 9 of the fixing part 1 with one edge of the continuous casting billet 12, then move the handle 5 to drive the pointer 8 to the diagonal of the billet, and read its value, which is the length of one diagonal of the continuous casting billet. Similarly, measure the length of the other diagonal. The difference between the two diagonals is the de-squareness.

[0027] The hand-held part 5 is a telescopic rod, which is connected by a buckle 6. The length of the hand-held part 5 can be flexibly adjusted according to the ambient temperature to achieve long-distance measurement of the diagonal length of the continuous casting billet and protect the safety of the operator. The telescopic rod is rotatably connected to the slider 7, and the angle can be adjusted according to different measurement environments, which is convenient to operate.

[0028] The measuring part 2 can slide up and down in the fixing part 1. During the measurement process, the measuring part 2 is moved downward to make the scale 4 contact with the surface of the continuous casting billet 12, so that the reading is more accurate.

[0029] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
