[0001] The utility model relates to the technical field of anti-deformation devices, in particular to an anti-deformation tooling for an electroslag remelting crystallizer copper tube and components thereof. Background Art

[0002] Electroslag remelting is a method of smelting that uses the resistance heat generated when electric current passes through molten slag as a heat source. Its purpose is to purify the metal and obtain a clean, uniformly dense steel ingot. The steel remelted by electroslag has high purity, low sulfur content, few non-metallic inclusions, smooth ingot surface, clean, uniformly dense, uniform metallographic structure and chemical composition. The cast mechanical properties of electroslag steel can reach or exceed the standards of the same steel forgings.

[0003] Electroslag remelting is carried out in the copper tube of the crystallizer. This type of copper tube has a large inner cavity and a long length. It is difficult to ensure the integrity of the integral copper tube using conventional extrusion equipment. In order to ensure that the ingot has a good cross-sectional size and can be smoothly ejected during use, the copper tube is required to have good straightness in the length direction. However, during the butt welding of two "["-shaped copper plates, the copper tube is very easy to deform during the welding process due to its long length, and the straightness is difficult to ensure.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0006] The second purpose of the utility model is to provide a tool for the reverse deformation of the copper tube of the electroslag remelting crystallizer, so as to solve the technical problem of the lack of tooling for the reverse deformation of the copper tube of the electroslag remelting crystallizer in the prior art.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] On the one hand, the utility model provides an anti-deformation tooling assembly for the copper tube of an electroslag remelting crystallizer, comprising a support member 2 and a straightness ensuring member 1 arranged between the support member 2 and the inner wall of the copper tube 6, wherein the surface of the straightness ensuring member 1 connected to the copper tube 6 is parallel to the surface where the straightness ensuring member 1 and the support member 2 are connected.

[0042] The copper tube 6 is formed by butt welding two "["-shaped copper plates. In order to ensure the straightness of the copper tube in the length direction, a straightness guarantee member 1 is arranged between the inner wall of the copper tube 6 and the support member 2. The straightness guarantee member 1 ensures that the support member 2 is in a straight state along the length direction of the copper tube 6 through two mutually parallel surfaces on the straightness guarantee member 1, thereby solving the problem that the support member in the prior art cannot ensure the straightness of the copper tube 6 in the length direction.

[0043] The anti-deformation tooling assembly has a simple and reasonable structure. The support member 2 pre-applies a supporting force from the inside to the outside to the copper tube, and cooperates with the straightness assurance member 1 to offset the shrinkage deformation of the copper tube during the welding process, thereby ensuring the overall straightness of the copper tube and the product quality, and has good practicality.

[0044] Since the copper tube 6 is generally long, the anti-deformation tooling assembly can be used more flexibly.

[0045] In some specific embodiments, an adjusting member is provided on the surface of the support member 2 opposite to the straightness ensuring member 1 , and the adjusting member is used to adjust the vertical distance between the support member 2 and the straightness ensuring member 1 .

[0046] The adjusting member can adjust the vertical distance between the supporting member 2 and the straightness ensuring member 1 , so that the anti-deformation tooling assembly can be tightly connected to the inner wall of the copper tube 6 at any position on the copper tube 6 .

[0047] In some specific embodiments, the support member 2 includes a longitudinal support member 21 and a transverse support member 22 fixed on the longitudinal support member 21 , and both ends of the longitudinal support member 21 and the transverse support member 22 are connected to the inner wall of the copper tube 6 through a straightness ensuring member 1 .

[0048] The longitudinal support member 21 provides longitudinal support for the inner wall of the copper tube, and the transverse support member 22 provides transverse support for the inner wall of the copper tube. The longitudinal support member 21 and the transverse support member 22 cooperate with each other to support the copper tube 6 in both the transverse and longitudinal directions, and the force is evenly distributed.

[0049] In some specific embodiments, ribs 3 are provided on both sides of the intersection of the longitudinal support member 21 and the transverse support member 22 , and the ribs 3 on both sides cooperate with each other to limit the displacement of the transverse support member 22 along the extension direction of the longitudinal support member 21 .

[0050] In order to improve the firmness of the connection between the longitudinal support member 21 and the transverse support member 22, a rib plate 3 is provided to prevent the transverse support member 22 from longitudinal displacement under the action of external force, thereby further improving the supporting force of the anti-deformation tooling assembly.

[0051] In some specific embodiments, one end of the longitudinal support member 21 is a reference end, and the other end is an adjustment end;

[0052] Both ends of the transverse support member 22 are adjustment ends;

[0053] The adjusting member is arranged on the adjusting end.

[0054] No adjusting member is provided at the reference end, and the longitudinal support member 21 cooperates with the straightness guarantee member 1 to provide a reference for the anti-deformation tooling assembly to ensure the straightness of the copper tube 6 in the extension direction, thereby improving the anti-deformation capability of the anti-deformation tooling assembly.

[0055] In some specific embodiments, the adjusting member includes fixing nuts 5 arranged on both sides of the adjusting end and adjusting bolts 4 threadedly matched with the fixing nuts 5 , and one end of the adjusting bolt 4 away from the supporting member 2 is connected to the straightness ensuring member 1 .

[0056] By adjusting the screw thread connection between the adjusting bolt 4 and the fixing nut 5, the position of the adjusting bolt 4 in the screw thread connection of the fixing nut is changed, and the tightness of the connection between the supporting member 2 and the straightness ensuring member 1 is adjusted.

[0057] When the anti-deformation tooling assembly is in working state, the tightness can be adjusted to increase to increase the supporting force of the anti-deformation tooling assembly on the copper tube 6; when the anti-deformation tooling assembly needs to be moved, the tightness can be adjusted to decrease to separate the anti-deformation tooling assembly from the copper tube and move it to a suitable position.

[0058] In some specific implementations, the surface of the straightness ensuring member 1 connected to the copper tube 6 is parallel to the surface of the straightness ensuring member 1 connected to the adjusting bolt 4 .

[0059] By ensuring that the surface of the straightness ensuring component 1 connected to the copper tube 6 is parallel to the surface connected to the adjusting bolt 4, it can be ensured that the surfaces of the adjusting bolt 4 connected to the fixing nuts 5 on both sides of the adjusting end that are in contact with the straightness ensuring component 1 are in the same horizontal plane and parallel to the inner wall of the copper tube 6, thereby ensuring the overall straightness of the copper tube.

[0060] In some specific embodiments, the two ends of the longitudinal support member 21 are coaxially arranged with the corresponding straightness ensuring member 1, and the two ends of the transverse support member 22 are coaxially arranged with the corresponding straightness ensuring member 1, and the axial direction of the straightness ensuring member 1 is perpendicular to the axial direction of the copper tube 6.

[0061] The two ends of the longitudinal support member 21 are respectively arranged coaxially with the corresponding straightness ensuring member 1 to prevent the support member 2 and the straightness ensuring member 1 from being offset due to unstable center of gravity during use, causing the adjusting member to separate from the straightness ensuring member 1.

[0062] In some specific implementations, the vertical distance between the axis centers of the fixing nuts 5 on both sides of the adjustment end is ≤ the extension distance of the straightness ensuring member 1 in the direction perpendicular to the copper tube 6 .

[0063] It is ensured that the straightness ensuring member 1 provides sufficient supporting and connecting space for the fixing nut 5 to prevent the fixing nut 5 from being separated from the straightness ensuring member 1 due to external force.

[0064] On the other hand, the utility model also provides an anti-deformation tool for the copper tube of the electroslag remelting crystallizer, comprising a plurality of the above-mentioned anti-deformation tool components;

[0065] Preferably, several anti-deformation tooling components are coaxially arranged.

[0066] The anti-deformation tooling of the copper tube of the electroslag remelting crystallizer can ensure the straightness of the copper tube along the extension direction of the length of the copper tube through the cooperation of several anti-deformation tooling components, and further realize the anti-deformation capability for the longer copper tube 6.

[0068] Combination Figure 1 to Figure 5 To illustrate, an anti-deformation tooling assembly for an electroslag remelting crystallizer copper tube includes a straightness guarantee part 1, a longitudinal support part 21, and a transverse support part 22, wherein: a fixing nut 5 is provided on the upper and lower sides of both ends of the transverse support part 22 in the length direction, and a fixing nut 5 is provided on the left and right sides of one end of the longitudinal support part 21 in the length direction, and the other end is not provided with a fixing nut, which is the reference end. An adjusting bolt 4 matching the screw hole of the fixing nut 5 is selected. The spacing between the center holes of the two fixing nuts 5 at the same end of the support part 2 is ≤ the width of the straightness guarantee part 1, ensuring that the adjusting bolt 4 can tighten the straightness guarantee part 1 after being installed.

[0069] The transverse support member 22 is fixedly arranged at the middle position of the waist of the longitudinal support member 21, and a rib plate 3 is arranged at the angle between the transverse support member 22 and the longitudinal support member 21 to ensure that the two support members are fixed more firmly.

[0070] Example 2

[0071] Combination Figure 1 to Figure 5 To illustrate, an anti-deformation tooling for a copper tube of an electroslag remelting crystallizer is provided. In this embodiment, two "["-shaped copper plates are butt-jointed into a copper tube. The length of the copper tube 6 is 2.8 meters. Four anti-deformation tooling assemblies for the copper tube of an electroslag remelting crystallizer provided in Example 1 are provided. The four anti-deformation tooling assemblies are sequentially placed in the inner cavity of the copper tube 6. The adjusting bolt 4 is adjusted so that the straightness guarantee member 1 is pressed against the inner wall of the copper tube and a certain deformation margin is retained. The two butt joint gaps are alternately welded until the butt welding is completed. After the copper tube 6 is cooled, the anti-deformation tooling assembly is removed.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
