Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting billet width measurement, in particular to a tool for quickly measuring the width of a hot billet. Background Art

[0002] In the steelmaking process, molten steel is cast into billets of a certain size by a continuous casting machine and then transferred to the rolling process for rolling. The size control of the billet, especially the width control, will have a great impact on the subsequent rolling quality. If the billet width control does not match the planned product size, a large number of unplanned products will be produced, causing great losses. Steelmaking continuous casting equipment generally has billet size setting and online detection functions, but in continuous production, due to the harsh working environment, the accuracy of the continuous casting equipment will be reduced, and the shrinkage ratio of different steel grades is also slightly different. In order to confirm the equipment accuracy and ensure that the billet width meets the requirements, it is necessary to manually check the billet size regularly.

[0003] At present, rulers or tape measures are generally used to accurately measure hot steel billets. When using rulers or tape measures for measurement, there are the following problems: using rulers or tape measures requires close contact with the hot steel billet, which is prone to burns; the numbers and scales on the rulers or tape measures are small, which is not easy to read in a high temperature environment; rulers or tape measures are easily damaged when used in a high temperature environment and are not suitable for long-term use. Therefore, there is an urgent need for a tool for quickly measuring the width of hot steel billets. Utility Model Content

[0008] Preferably, the first connecting rod and the second connecting rod are both telescopic rods. The lengths of the first connecting rod and the second connecting rod can be adjusted according to work needs. For hot steel billets with very high temperatures, the elongated lengths of the first connecting rod and the second connecting rod can be appropriately increased, thereby increasing the distance between the scale and the steel billet, making it easier for workers to observe the scale and avoid high temperature burns.

The position of the push rod and the movable limit rod can be fixed by the cooperation of the limit nut and the limit screw. When the position of the movable limit rod needs to be adjusted, the limit nut is loosened, the push rod and the limit screw are pushed, the first sliding sleeve moves along the main arm, the second sliding sleeve moves along the scale, and the limit screw moves in the long through hole. By pushing the push rod and the limit screw, the movable limit rod can be avoided from being directly pushed, away from the hot billet, and burns can be avoided. Tightening the limit nut can fix the limit screw through the limit nut, thereby fixing the position of the movable limit rod, the first sliding sleeve, and the second sliding sleeve.

When measuring the width of the hot steel billet, the fixed limit rod and the movable limit rod are used to clamp the two sides of the steel billet. At this time, the scale of the first end of the second sliding sleeve on the scale is the width of the steel billet.

[0012] Preferably, in order to better observe the scale, a magnifying glass for observing the scale lines is fixed on the second sliding sleeve.

[0013] Preferably, a vertical plate is fixed on the second sliding sleeve, and the handle of the magnifying glass is connected to the vertical plate by bolts.

[0024] A scale 4 parallel to the main arm 1 is arranged above the main arm 1, a first sliding sleeve 5 movable along the main arm 1 is installed on the main arm 1, a second sliding sleeve 6 movable along the scale 4 is installed on the scale 4, the first sliding sleeve 5 and the second sliding sleeve 6 are connected and fixed by a first connecting rod 7, the first sliding sleeve 5 is fixed to the movable limiting rod 3, and the first sliding sleeve 5 and the second sliding sleeve 6 move synchronously with the movable limiting rod 3. The first sliding sleeve 5 is sleeved on the main arm 1, and the second sliding sleeve 6 is sleeved on the scale 4.

[0025] In order to enhance the stability of the scale 4, the head end of the scale 4 is connected to the main arm 1 through the second connecting rod 8. In this embodiment, the first connecting rod 7 and the second connecting rod 8 are telescopic rods, and the lengths of the first connecting rod 7 and the second connecting rod 8 can be adjusted according to work needs. For hot steel billets with very high temperatures, the elongation lengths of the first connecting rod 7 and the second connecting rod 8 can be appropriately increased, thereby increasing the distance between the scale 4 and the steel billet, making it convenient for staff to observe the scale and avoid high temperature burns. The telescopic rod includes an inner rod and an outer rod sleeved outside the inner rod. A locking bolt 9 for fixing the inner rod is passed through the outer rod, and the inner rod and the outer rod are fixed by the locking bolt 9.

[0026] The movable limiting rod 3 is connected to the push rod 10, and the push rod 10 is parallel to the main arm 1. The limiting screw 11 is vertically fixed on the push rod 10, and a long through hole is set on the main arm 1. The limiting screw 11 passes through the long through hole and is connected with the limiting nut 12. The position of the push rod 10 and the movable limiting rod 3 can be fixed by the cooperation of the limiting nut 12 and the limiting screw 11. When it is necessary to adjust the position of the movable limiting rod 3, the limiting nut 12 is loosened, the push rod 10 and the limiting screw 11 are pushed, and the first sliding sleeve 5 moves along the main arm 1, the second sliding sleeve 6 moves along the scale 4, and the limiting screw 11 moves in the long through hole. By pushing the push rod 10 and the limiting screw 11, the movable limiting rod 3 can be avoided from being directly pushed, away from the hot billet, and scalding can be avoided. Tightening the limiting nut 12 can fix the limiting screw 11 through the limiting nut 12, thereby fixing the position of the movable limiting rod 3, the first sliding sleeve 5 and the second sliding sleeve 6.

Before lifting, the utility model is placed on the billet so that the fixed limit rod 2 and the movable limit rod 3 are located on both sides of the billet. One hand holds the handle 15, and the other hand holds the push rod 10 or the limit screw 11 and pushes it forward. When the fixed limit rod 2 and the movable limit rod 3 clamp the billet, confirm that the fixed limit rod 2 and the movable limit rod 3 remain vertical to the billet, tighten the limit nut 12, and observe the scale at the head end of the second sliding sleeve 6 through the magnifying glass 13 and write down the value. Then loosen the limit nut 12 and remove the utility model from the billet. Use the above method to measure the width of the head, middle and tail of the billet respectively, and write down the values ​​respectively to complete the width measurement of the hot billet.

[0030] The utility model has a simple structure. The width of the hot steel billet can be obtained by observing the scale at the head end of the second sliding sleeve 6. When observing the scale, there is no need to make close contact with the high-temperature steel billet, and the scale value can be quickly and conveniently viewed through the magnifying glass 13. When performing the width measurement operation, one hand holds the handle 15, and the other hand pushes the push rod 10 or the limit screw 11.
