Description

TECHNICAL FIELD

[0001] The utility model relates to the field of steel manufacturing, specifically relates to an improved dummy block. BACKGROUND

[0002] At present, straight cylinder submerged entry nozzle is used in large round billet continuous casting, and molten steel directly falls through pipeline, due to only one downward nozzle, in use, due to the jetting action and the gravity action of molten steel, the molten steel quickly downward, the connecting effect formed is not very good, therefore, the nozzle is modified to the style of side water outlet, multiple nozzle, by changing the water outlet direction, thereby slow down the jetting speed of molten steel, and the middle part of the matched dummy block is provided with a cross connecting rod, when the equipment is improved, the multiple hole nozzle is matched, that is, the steel flow does not flow out from the lower part of the nozzle, but flows out from four sides, due to the nozzle is relatively close to the flange of the crystallizer, the molten steel is easy to jet to the upper opening of the crystallizer from the side hole of the nozzle, thereby causing copper pipe wall hanging steel, thereby causing the accident of molten steel leakage, therefore, an improved dummy block is required to be used with the multiple hole nozzle. SUMMARY

[0003] The utility model provides an improved dummy block, through setting the ring body that sets from top to bottom in proper order, the nozzle can be directly inserted into the dummy block in the middle part, thereby avoiding the problem that the molten steel of the nozzle jetting erodes the flange.

[0004] The utility model discloses an improved dummy block through the following technical scheme:

[0005] An improved dummy block, comprising, from top to bottom, coaxially arranged annular ring A, annular ring B and annular ring C, the outer side of the annular ring A, annular ring B and annular ring C is connected by a plurality of long rods, the annular ring A, annular ring B and annular ring C are sequentially reduced, and a cross connecting rod is arranged in the inner ring of the annular ring C to connect the inner ring of the annular ring C.

[0006] Further, the annular ring A and annular ring B are coaxially provided with auxiliary rings, and the diameter of the auxiliary ring is less than the diameter of the annular ring B and greater than the diameter of the submerged entry nozzle to be inserted.

[0007] Further, the auxiliary ring and the annular ring A and annular ring B are fixedly connected by connecting rods.

[0008] Further, a plurality of notches are arranged on the inner side of the long rod along the length direction.

[0009] Further, the depth of the notch is 1 / 3 to 1 / 2 of the diameter of the long rod.

[0010] Further, the whole dummy block is made of high-carbon steel.

[0011] The utility model has the advantages that,

[0012] By setting the circular ring A, the circular ring B, the circular ring C, by setting the long rod connection on the outside, so that the invasive water pipe can be directly inserted into the dummy block, avoid the problem of molten steel spraying to the flange, in addition, by setting the auxiliary ring, increase the overall stability of the dummy block and the connection effect, at the same time, the notch in the long rod can better increase the adhesion of molten steel and the dummy block. BRIEF DESCRIPTION OF DRAWINGS

[0013] The accompanying drawings are included to provide a further understanding of the present application, and constitute a part of the specification, illustrate the present application, and are used to explain the present application, and do not constitute a limitation on the present application. In the drawings:

[0014] Figure 1 It is a structural schematic diagram of the present application. DETAILED DESCRIPTION

[0015] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and do not limit the present application.

[0016] As Figure 1 As shown in a kind of improved dummy block, including, from top to bottom, circular ring A10, circular ring B20, circular ring C30 are sequentially coaxially arranged, the circular ring A10, circular ring B20, circular ring C30 outside is connected by multiple long rods 40, the circular ring A10, circular ring B20, circular ring C30 are sequentially reduced, the circular ring C30 is provided with cross connecting rod 301 in the inner circle of circular ring C30, the circular ring A10, circular ring B20 are coaxially provided with auxiliary ring 50 respectively, the diameter of the auxiliary ring 50 is less than the diameter of the circular ring B20, greater than the diameter of the invasive water pipe to be inserted, the auxiliary ring 50 and the circular ring A10, circular ring B20 are fixedly connected between the circular ring B20 respectively by connecting rod 60. When using, invasive water pipe is directly inserted into auxiliary ring 50, so that multiple water ports laterally spray molten steel, so as to avoid the problem of molten steel spraying damage flange.

[0017] Further, in order to improve the adhesion of molten steel and the dummy block in the vertical direction, the long rod 40 is provided with a plurality of notches 401 along the length direction, the notch depth is 1 / 3~1 / 2 of the diameter of the long rod 10, and the dummy block is made of high carbon steel.
