Description

Technical Field

[0001] This utility model relates to the field of steel production technology, specifically to a tool for assisting in the installation of chamfering foot rollers for continuous casting slabs. Background Technology

[0002] A crystallizer is a continuous steel casting device that receives molten steel poured from the tundish and solidifies it into a solid billet shell according to a specified cross-sectional shape. The foot rolls of the crystallizer are devices that support the billet after it exits the crystallizer. A chamfered crystallizer is a type of crystallizer. In the production process of a chamfered crystallizer, chamfered foot rolls are designed to ensure continued support of the chamfered billet by the foot rolls after exiting the crystallizer. The chamfered foot rolls are an extension of the chamfered crystallizer and have an arc-shaped measuring surface 102. The parameters of the arc-shaped measuring surface 102 are derived from the parameters of the copper plate of the chamfered crystallizer. See [link to relevant documentation]. Figure 1 The chamfered crystallizer copper plate includes two vertical surfaces 202, a wide bottom surface 201, two inclined surfaces 203, and a short top surface 204. The two vertical surfaces 202 are parallel and opposite to each other. The opposite ends of the wide bottom surface 201 are connected to one end of the two vertical surfaces 202. One end of the two inclined surfaces 203 is connected to one end of the two vertical surfaces 202 away from the wide bottom surface 201, and the other ends of the two inclined surfaces 203 extend towards each other. The short top surface 204 is parallel to the wide bottom surface 201, and the opposite two sides of the short top surface 204 are connected to one end of the two inclined surfaces 203 away from the corresponding vertical surface 202. During the installation of the chamfering foot roller, its parameters need to be adjusted by adjusting the two parallel fixing screws 101 on the chamfering foot roller. However, since there is no tool to measure the parameters of the chamfering foot roller, it is impossible to quickly measure the parameters of the chamfering foot roller that meet the expectations, resulting in a long time required for each measurement and installation of the chamfering foot roller. Therefore, a tool is needed to assist in adjusting the parameters of the chamfering foot roller of the continuously cast slab. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems mentioned above by providing a tool for assisting in the installation of chamfering foot rollers for continuous casting slabs, which can assist in adjusting the parameters of the chamfering foot rollers for continuous casting slabs.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A tool for assisting in the installation of chamfering foot rollers for continuous casting slabs includes a comparison flat surface, two inclined surfaces, and a hand-held part. One end of the two inclined surfaces is connected to one end of the comparison flat surface, and the other ends of the two inclined surfaces extend in opposite directions. The two inclined surfaces can fit into an arc-shaped measuring surface. The hand-held part is connected to the ends of the two inclined surfaces that are opposite to the comparison flat surface.

[0006] Furthermore, the comparison plane, the two inclined planes, and the handheld part are arranged in an isosceles trapezoid.

[0007] Furthermore, the handheld part is a parallel surface, which is parallel to and opposite to the comparison straight surface, and the two opposite ends of the parallel surface are connected to the ends of the two inclined surfaces that are away from the comparison straight surface.

[0008] Furthermore, the angle formed by the two inclined surfaces and the comparative straight surface is equal to the angle formed by the two inclined plate surfaces and the short top surface.

[0009] Furthermore, its shape is a flat plate.

[0010] Furthermore, its material is stainless steel.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects:

[0012] When using the aforementioned tool for assisting in the installation of chamfering foot rollers for continuous casting slabs, after fixing the chamfering foot roller to the foot roller frame, hold the tool by the handle and place it in a comparison position. This position is where the central axis of the installed chamfering foot roller is parallel to the comparison flat surface. Keeping the position of the tool unchanged, turn the two fixing screws to adjust the parameters of the chamfering foot roller. During the adjustment process, use a feeler gauge to measure the gap between the inclined part of the arc measuring surface and the two inclined surfaces. When the gap between the arc measuring surface and the two inclined surfaces and the comparison flat surface is less than 0.1mm, it indicates that the parameter meets the process requirements, and the installation of the chamfering foot roller is complete. Therefore, this utility model can assist in adjusting the parameters of the chamfering foot roller for continuous casting slabs. Attached Figure Description

[0020] like Figure 2 and Figure 3 As shown, a preferred embodiment of the present invention provides a tool for assisting in the installation of chamfering foot rollers for continuous casting slabs, comprising a comparison flat surface 1, two inclined surfaces 2 and a hand-held part 3. One end of the two inclined surfaces 2 is connected to one end of the comparison flat surface 1, and the other ends of the two inclined surfaces 2 extend in opposite directions. The two inclined surfaces 2 can fit against the arc-shaped measuring surface 102. The hand-held part 3 is connected to the ends of the two inclined surfaces 2 that are opposite to the comparison flat surface 1.

[0021] When using the aforementioned tool for assisting in the installation of chamfering foot rollers for continuous casting slabs, after fixing the chamfering foot roller 100 to the foot roller frame, hold the handle 3 and place the tool at a comparison position. This position is where the central axis 103 of the installed chamfering foot roller 100 is parallel to the comparison flat surface 1. Keeping the position of the tool unchanged, turn the two fixing screws 101 with the other hand to adjust the parameters of the chamfering foot roller. During the adjustment process, use a feeler gauge to measure the gap between the arc-shaped measuring surface 102 and the two inclined surfaces 2. When the gap between the inclined part of the arc-shaped measuring surface 102 and the two inclined surfaces 2 and the comparison flat surface 1 is less than 0.1mm, it indicates that the parameter meets the process requirements, and the installation of the chamfering foot roller 100 is complete. Therefore, this utility model can assist in adjusting the parameters of the chamfering foot roller for continuous casting slabs.

[0022] In this embodiment, the handheld part 3 is a parallel surface, which is parallel to and opposite to the comparison straight surface 1. The two opposite ends of the parallel surface are connected to the two inclined surfaces 2 that are away from the end of the comparison straight surface 1, so that the comparison straight surface 1, the two inclined surfaces 2 and the handheld part 3 form an isosceles trapezoid.

[0023] In this embodiment, the angle formed by the two inclined surfaces 2 and the comparison flat surface 1 is equal to the angle formed by the two inclined plate surfaces 203 and the short top surface 204, so that the two inclined surfaces 2 can fit into the arc-shaped measuring surface 102.

[0024] In this embodiment, the tool for assisting in the installation of the chamfering foot roller of the continuous casting slab is shaped like a flat plate and is made of stainless steel.

[0025] It is understood that the shape of the tool for assisting in the installation of the chamfering foot roller of the continuous casting slab is not limited to the plate-shaped isosceles trapezoid in this embodiment. In other embodiments, the tool for assisting in the installation of the chamfering foot roller of the continuous casting slab can be a plate-shaped pentagon including a relatively flat surface 1, two inclined surfaces 2 and a hand-held part 3.

[0026] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
