Description

Technical Field

[0001] The utility model relates to the field of arc alignment of continuous casting machines, in particular to an arc alignment template operating frame device of a continuous casting machine. Background Art

[0002] At present, the continuous casting machines in our factory are mainly arc-type continuous casting machines, and there are two models, R9 meter arc and R6 meter arc. In normal production, due to the wear of the rollers that maintain the R9 meter arc and R6 meter arc and the deformation of the frame in the secondary cooling room, the curvature of the continuous casting machine needs to be adjusted regularly. The standard for adjusting the arc is to use a section of R9 meter arc and R6 meter arc template (only 1 / 3 of the length of the entire secondary cooling arc) and put it into the secondary cooling room as a "ruler" to adjust the entire secondary cooling room arc into place section by section, so as to ensure that the billet can be pulled out smoothly. At present, when the continuous casting machine in our factory is aligned with the arc, the template is placed in the secondary cooling room by a crane. In particular, during the arc alignment process, the position of the template must be constantly adjusted by the crane. This will affect other continuous casting machines in normal production during the arc alignment process. In order to ensure the normal production of continuous casting in production, we have to wait until the crane is used during the production interval when it is needed. This greatly increases the arc alignment time and affects the normal production of this continuous casting machine. The disadvantages of this are:

[0003] 1) Increase the arcing time.

[0004] 2) Using a crane to constantly adjust the position of the sample requires multiple people to operate, increasing labor.

[0005] 3) Using a crane to constantly adjust the position of the template affects the normal production of other continuous casting machines.

[0006] Therefore, how to adjust the position of the template conveniently and quickly when the continuous casting machine is aligned needs further improvement. Utility Model Content

[0007] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide an arc template operating frame device for a continuous casting machine, which has the advantages of being simple and feasible, easy to maintain and low in cost.

[0008] The purpose of the utility model is achieved through the following technical solutions: This continuous casting machine arc template operating frame device includes a crystallizer, a frame, an arc template, a pulley and a rope. The bottom of the frame is fixed to the crystallizer through a base, and the frame is supported by a pulley through a bearing seat. The arc template is placed in the second cooling chamber. The operator holds one end of the rope, passes the other end of the rope through the pulley and then ties it to the arc template, and uses manpower to pull the arc template up and down to realize the arc operation.

[0009] As a further technical solution, the base is in an "L"-shaped structure, which is used to be clamped on the upper flange of the crystallizer, and a fixing screw hole is provided on the base to be locked and fixed with the upper flange by bolts.

[0010] As a further technical solution, two bearing seats are fixed on the top of the frame, and an axial hole is formed through each bearing seat for installing a pulley shaft, and the pulley is supported on the bearing seat through the pulley shaft.

[0011] The beneficial effects of the utility model are:

[0012] 1. Reduce arcing time;

[0013] 2. No need to use a crane to constantly adjust the position of the sample, avoiding multi-person operation and reducing labor costs;

[0014] 3. Avoid using the crane to constantly adjust the position of the template and affect the normal production of other continuous casting machines;

[0015] 4. It is highly operable, with sufficient installation space on site, and will not affect any aspect of the continuous casting production;

[0016] 5. Easy maintenance. This system only needs to regularly check the wear of the fixed pulley. Other parts do not require any maintenance under normal circumstances. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is a detailed introduction to the present invention with reference to the accompanying drawings:

[0026] Example: As shown in the attached Figures 1 to 7 As shown, the arc template operating frame device of the continuous casting machine includes a crystallizer 1, a base 2, a frame 3, an arc template 4, an operator 5, a pulley 6, a rope 7, a bearing seat 8, a pulley shaft 9, an upper flange 10, a fixing screw hole 11 and an axis hole 12.

[0027] Reference Attachment Figure 1 、 2 , four feet 2 are welded and fixed at the bottom of the frame 3, and further, as Figure 4 、 5 As shown, the base foot 2 adopts an "L"-shaped structure, which can be inserted into the upper flange 10 of the crystallizer 1 (on the corresponding four corners), and a fixing screw hole 11 is provided on the side of the base foot 2. The fixing screw hole 11 can cooperate with the bolt to lock the upper flange 10 and the base foot 2 to prevent the frame 3 from being detached from the crystallizer 1. When in use, the frame 3 does not shake in the up, down, left, right, front and rear directions, and the fixing screw hole 11 can realize the rapid disassembly of the base foot 2 and the crystallizer 1.

[0028] In addition, a pulley 6 (a fixed pulley) is supported on the frame 3 through a bearing seat 8. The arc template 4 is placed in the second cooling chamber. The operator 5 holds one end of the rope 7, passes the other end of the rope 7 through the pulley 6 and then ties it to the arc template 4, thereby manually pulling the arc template 4 to achieve the arc operation.

[0029] like Figure 2 、 6 As shown in Figures 7 and 7, two bearing seats 8 are welded and fixed on the top of the frame 3. An axial hole 12 is formed through each bearing seat 8. A pulley shaft 9 is passed through the axial hole 12, and the pulley 6 is supported on the bearing seat 8 through the pulley shaft 9.

[0030] Working process of utility model:

[0031] Each time the arc is aligned, the crystallizer 11 is lifted open, the arc template 4 is placed in the second cooling chamber, and then the crystallizer 1 is lifted in. There is no need to use a crane to complete the arc alignment later. The main thing is to install the special continuous casting arc template operating frame device (frame 3) on the upper flange 10 of the crystallizer 1 and fix it so that the four bottom feet 2 are stuck on the four corresponding corners of the upper flange 10 and fixed with the fixing screw holes 11. Then, as Figure 3 As shown, the operator 5 holds one end of the rope 7, passes the rope 7 through the pulley 6 and is tied to the arc template 4, and manually pulls the arc template 4 up and down to complete the arc operation. This saves time for each maintenance of the arc.

[0032] Based on the current frequency of aligning 10 streams every two months, the use of this utility model saves one hour per stream. This annual time savings is: W = 12 ÷ 2 × 10 × 1 = 60 hours. Each machine produces 90 tons of steel per hour, resulting in an additional annual output of: Q = 60 × 90 = 5,400 tons of steel per year. The converter's profit per ton of steel is 2,000 yuan, resulting in an annual economic benefit of: M = 5,400 × 2,000 = 10,800,000 yuan, or 10.8 million yuan.

[0033] It is understandable that for those skilled in the art, any equivalent replacement or change of the technical solution and the concept of the utility model should fall within the scope of protection of the claims attached to the utility model.
