Description

Technical Field

[0001] The utility model relates to the technical field of electroslag remelting in metallurgical machinery industry, in particular to an elliptical flat ingot crystallizer. Background Art

[0002] The electroslag remelting crystallizer is an essential supporting equipment for the electroslag furnace equipment to produce electroslag steel ingots. During the remelting process, cooling water flows in from the water inlet pipe at the bottom of the crystallizer, passes through the cooling layer between the copper inner sleeve of the crystallizer and the steel plate outer shell, and flows out from the water outlet pipe at the top of the crystallizer. The molten steel in the smelting process in the crystallizer is cooled according to the designed process conditions, the crystallization speed of the molten steel is controlled, and it solidifies into electroslag steel ingots.

[0003] The current structural form of the electroslag flat ingot crystallizer is mainly a flat plate crystallizer. The copper plate of this electroslag flat ingot crystallizer is flat, and the plane of the copper plate is usually very wide and high, and its ability to resist high-temperature deformation is weak. During the electroslag remelting process, the temperature difference between the two sides of the copper plate is as high as 1650℃ or more. Due to the general law of thermal expansion and contraction of objects, the huge temperature difference between the two sides of the copper plate during the electroslag remelting process will inevitably cause the copper plate to bend toward the high-temperature surface. After repeated use for several times, the copper plate will cause a large plastic deformation and affect the normal use of the crystallizer. The flatter and wider the copper plate, the greater the deformation of the copper plate, and the more likely it is to have problems. Utility Model Content

[0004] The utility model aims to solve the defects of the prior art and provide an elliptical flat ingot crystallizer, which can not only be flexibly converted, but also achieve the advantages of the flat ingot being not easily deformed, having a long service life and high safety.

[0005] The utility model adopts the following technical solutions:

[0006] An elliptical flat ingot crystallizer comprises two semicircular crystallizers and two plate crystallizers.

[0008] Among them, the semicircular crystallizer copper plate is arc-shaped, and both ends of the semicircular crystallizer copper plate are welded and fixed on two semicircular crystal connecting ribs. The semicircular crystallizer shell and the semicircular crystallizer copper plate are concentrically arranged, and both ends of the semicircular crystallizer shell are also welded and fixed on the original two semicircular crystal connecting ribs, so that a semicircular crystallizer water seam is formed between the semicircular crystallizer copper plate and the semicircular crystallizer shell, the top of the semicircular crystallizer copper plate and the semicircular crystallizer shell are sealed by welding the semicircular crystallizer top plate, and the bottom of the semicircular crystallizer copper plate and the semicircular crystallizer shell are sealed by welding the semicircular crystallizer bottom plate.

[0009] The semicircular crystallizer water inlet pipe and the semicircular crystallizer water outlet pipe are welded on the semicircular crystallizer shell, and the semicircular crystallizer water outlet pipe is located on the upper side of the semicircular crystallizer water inlet pipe.

[0011] Among them, two plate-type crystallizer module connecting ribs are welded at both ends of the flat crystallizer copper plate, and both ends of the plate-type crystallizer module shell are also welded to the original two plate-type crystallizer module connecting ribs. So that a plate-type crystallizer module water gap is formed between the flat crystallizer copper plate and the plate-type crystallizer module shell, the top of the flat crystallizer copper plate and the plate-type crystallizer module shell is sealed by welding the plate-type crystallizer top plate, and the bottom of the flat crystallizer copper plate and the plate-type crystallizer module shell is sealed by welding the plate-type crystallizer bottom plate.

[0012] The water inlet pipe of the plate crystallizer module and the water outlet pipe of the plate crystallizer module are respectively welded on the outer shell of the plate crystallizer module, and the water outlet pipe of the plate crystallizer module is located on the upper side of the water inlet pipe of the plate crystallizer module.

[0013] When the semicircular crystal connecting ribs of the two semicircular crystallizers and the plate crystallizer module connecting ribs of the two plate crystallizers are connected and fixed with bolts, an elliptical flat ingot crystallizer is formed.

[0014] Furthermore, the semicircular crystallization connection rib is provided with 6 semicircular crystallizer rib bolt holes.

At the same time, the service life of the copper plate of the combined ingot crystallizer is improved, and it is particularly suitable for the production of 5-20 ton electroslag flat ingots.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model is described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-3 As shown, an elliptical flat ingot crystallizer of the utility model comprises two semicircular crystallizers 1 and two plate crystallizers 2.

[0025] The semicircular crystallizer 1 is welded together by a semicircular crystallizer copper plate 3, a semicircular crystallizer shell 17, a semicircular crystallizer top plate 7, a semicircular crystallizer bottom plate 8, a semicircular crystallization connecting rib plate 5, a semicircular crystallizer water inlet pipe 13, and a semicircular crystallizer water outlet pipe 14.

[0026] Among them, the semicircular crystallizer copper plate 3 is arc-shaped, and the two ends of the semicircular crystallizer copper plate 3 are welded and fixed on two semicircular crystallization connecting ribs 5. The semicircular crystallizer shell 17 and the semicircular crystallizer copper plate 3 are concentrically arranged, and the two ends of the semicircular crystallizer shell 17 are also welded and fixed on the original two semicircular crystallization connecting ribs 5, so that a semicircular crystallizer water seam 11 is formed between the semicircular crystallizer copper plate 3 and the semicircular crystallizer shell 17. The top of the semicircular crystallizer copper plate 3 and the semicircular crystallizer shell 17 are sealed by welding the semicircular crystallizer top plate 7, and the bottom of the semicircular crystallizer copper plate 3 and the semicircular crystallizer shell 17 are sealed by welding the semicircular crystallizer bottom plate 8.

[0027] The semicircular crystallizer water inlet pipe 13 and the semicircular crystallizer water outlet pipe 14 are welded to the semicircular crystallizer shell 17 , and the semicircular crystallizer water outlet pipe 14 is located on the upper side of the semicircular crystallizer water inlet pipe 13 .

[0028] The semicircular crystallization connection rib plate 5 is provided with six semicircular crystallizer rib plate bolt holes 19 .

[0029] When the semicircular connecting plates 5 of the two semicircular crystallizers 1 are connected and fixed by bolts, a complete circular crystallizer is assembled.

[0030] The plate crystallizer 2 is composed of a flat crystallizer copper plate 4, a plate crystallizer module housing 18, a plate crystallizer module connecting rib plate 6, a plate crystallizer top plate 9, a plate crystallizer bottom plate 10, a plate crystallizer module water inlet pipe 15, and a plate crystallizer module water outlet pipe 16.

[0031] Among them, two plate-type crystallizer module connecting ribs 6 are welded at both ends of the flat crystallizer copper plate 4, and both ends of the plate-type crystallizer module housing 18 are also welded to the original two plate-type crystallizer module connecting ribs 6. A plate-type crystallizer module water gap 12 is formed between the flat crystallizer copper plate 4 and the plate-type crystallizer module housing 18, and the top of the flat crystallizer copper plate 4 and the plate-type crystallizer module housing 18 is sealed by welding the plate-type crystallizer top plate 9, and the bottom of the flat crystallizer copper plate 4 and the plate-type crystallizer module housing 18 is sealed by welding the plate-type crystallizer bottom plate 10.

[0032] The plate-type crystallizer module water inlet pipe 15 and the plate-type crystallizer module water outlet pipe 16 are respectively welded to the plate-type crystallizer module housing 18 , and the plate-type crystallizer module water outlet pipe 16 is located on the upper side of the plate-type crystallizer module water inlet pipe 15 .

[0033] The plate-type crystallizer module connecting rib plate 6 is provided with six plate-type crystallizer module rib plate bolt holes 20 .

[0034] When the semicircular crystal connecting ribs 5 of the two semicircular crystallizers 1 and the plate crystallizer module connecting ribs 6 of the two plate crystallizers 2 are connected and fixed by bolts, a flat ingot crystallizer is assembled.

[0035] The utility model can also be flexibly matched according to production needs, and can be combined into a circular crystallizer and an electroslag flat ingot crystallizer of various specifications. More importantly, the copper plate of the flat ingot crystallizer is not easily deformed due to the change in structure.

[0036] The principle is:

[0037] The flat crystallizer copper plate 4 is much narrower in width than the copper plate of the flat ingot crystallizer of the same specification, and the thermal deformation condition of the flat crystallizer copper plate 4 in the working state is effectively improved.

[0038] The width of the original flat ingot crystallizer's overall copper plate structure is divided into three parts by the utility model, of which two parts are composed of two semicircular crystallizers 1, and their widths are respectively the radius of the two semicircular crystallizers 1, or the diameter of the combined circular crystallizer. In this way, the width of the flat crystallizer copper plate 4 of the plate crystallizer 2 is the width of the inner cavity of the elliptical flat ingot crystallizer of the utility model minus the radius of the two semicircular crystallizers 1. Usually, the ratio of the width to the thickness of the flat ingot crystallizer is 1.5 to 1.8, and the width of the flat crystallizer copper plate 4 of the plate crystallizer 2 is smaller than the diameter of the circular crystallizer. Such division brings the following benefits:

[0039] 1. The original flat ingot crystallizer is transformed from two flat copper plates into a circular structure with strong deformation resistance.

[0040] 2. The copper plate of the flat ingot crystallizer is reduced by about 60% from a very wide shape, and the width of the copper plate 4 of the flat crystallizer is reduced by more than 60%.

[0041] These two changes divide the original wide copper plate of the flat ingot crystallizer into three sections, two of which are converted into two semicircular crystallizers 1, whose total width accounts for more than 60% of the original copper plate, and the remaining flat crystallizer copper plate 4 accounts for less than 49% of the original copper plate. This greatly improves the deformation resistance of the flat crystallizer copper plate 4 on the plate crystallizer module 2 described in the utility model at high temperatures, and greatly improves the thermal deformation resistance of all copper plates of this elliptical flat ingot crystallizer.

[0042] The elliptical flat ingot crystallizer of the utility model utilizes the advantage of the strong deformation resistance of the circular crystallizer and avoids the weakness that the wider the wide copper plate, the worse the deformation resistance. It is designed to be convertible into a circular crystallizer and into a flat ingot crystallizer. At the same time, the service life of the elliptical flat ingot crystallizer is improved, and it is particularly suitable for the production of 5-20 ton large electroslag flat ingots.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
