Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and in particular to a universal movable riser. Background Technology

[0002] Ingot molds and risers are typically tightly connected. The riser is usually located at the top of the ingot mold. This tight connection is primarily to ensure that molten steel can smoothly rise from the main body of the ingot mold to the riser area during pouring. For example, in the casting of large ingots, the bottom edge of the riser will precisely align with the top edge of the ingot mold. This alignment may utilize a flange connection or a special sealing structure to ensure there are no gaps between them, preventing molten steel leakage.

[0003] From a functional perspective, risers are used to compensate for the shrinkage of steel ingots during the solidification process. When molten steel begins to solidify inside the ingot mold, it undergoes volume shrinkage. Because the molten steel in the ingot mold solidifies first from the edges and bottom, and last at the top, the molten steel in the riser continuously replenishes the shrinking parts of the ingot. The tight connection between the riser and the ingot mold ensures that the molten steel can flow naturally into the areas of the ingot mold that require shrinkage compensation under the influence of gravity.

[0004] The size of the riser and the size of the ingot mold are matched. The diameter or side length of the riser (for square risers) is usually determined based on the size of the ingot mold and the shape of the ingot. Generally, the riser diameter will be a certain proportion of the ingot mold diameter. For example, for some small ingots (diameter between 300 and 500 mm), the riser diameter may be 0.3 to 0.5 times the ingot mold diameter; for large ingots (diameter greater than 1000 mm), the riser diameter proportion may be appropriately reduced to about 0.2 to 0.3 times.

[0005] However, the matching design of risers and ingot molds limits the shape of ingots produced by the combination of risers and ingot molds, affecting the efficiency of tooling turnover. Utility Model Content

[0006] The technical problem this invention aims to solve is to provide an active riser that optimizes workshop production, thereby addressing the issue that split-type ingot molds cannot freely change ingot shape and improving the utilization rate of steel ingots.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A general-purpose movable riser includes two riser bodies, a riser outer edge disposed on the outer ring of the riser body, and several lifting lugs disposed on the riser outer edge.

[0009] A further improvement of this utility model is that the riser body is cylindrical, comprising a cylindrical outer wall and a frustum-shaped inner wall.

[0010] A further improvement of this utility model is that the outer edge of the riser is integrally designed with the riser body, the upper end face is flush with the upper end face of the riser body, and the lower end face is perpendicular to the outer wall of the riser body.

[0011] A further improvement of this utility model is that the width of the outer edge of the riser is in the range of 300-400mm.

[0012] A further improvement of this utility model is that the height of the outer edge of the riser is in the range of 300-400mm.

[0013] A further improvement of this utility model is that the lifting lugs are respectively set at both ends and the middle of the outer edge of the riser, and when the two riser bodies are spliced ​​together, the lifting lugs at both ends are combined into one lifting lug.

[0014] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0015] 1. This utility model achieves the technical effect of improving the turnover rate of tooling by redesigning the riser.

[0016] 2. This utility model improves the compatibility between the riser and its corresponding ingot mold, thereby shortening the box assembly time and improving the production efficiency of the workshop. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] In the description of this utility model, "a number of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] like Figure 1 , 2 As shown, a general-purpose movable riser includes two riser bodies 1, a riser outer edge 2 disposed on the upper outer ring of each riser body 1, and a plurality of lifting lugs 3 disposed on the riser outer edge 2;

[0024] The riser body 1 is cylindrical, including a cylindrical outer wall and a frustum-shaped inner wall;

[0025] The riser outer edge 2 is integrally designed with the riser body 1, with its upper end face flush with the upper end face of the riser body 1 and its lower end face perpendicular to the outer wall of the riser body 1; the width of the riser outer edge 2 ranges from 300 to 400 mm, and its height ranges from 300 to 400 mm.

[0026] The lifting lugs 3 are respectively set at both ends and in the middle of the outer edge 2 of the riser. When the two riser bodies 1 are spliced ​​together, the lifting lugs 3 at both ends are combined into one lifting lug 3.

[0027] Example 1

[0028] A general-purpose movable riser, which consists of two riser bodies 1 assembled into one, has an upper diameter of 1400mm, a lower diameter of 1720mm, an outer wall diameter of 1865mm, an outer edge diameter of 2480mm, a riser body 1 height of 1200mm, and an outer edge height of 200mm.

[0029] How to use:

[0030] After the riser is properly hung, the riser is closed and placed above the ingot mold by the lifting lug 3. The outer edge 2 of the riser plays a fixing role, and is placed on the edge of the ingot mold, thereby extending the riser into the ingot mold and fixing it.

[0031] In summary, this utility model solves the problem that split-type ingot molds cannot freely change the ingot shape, thereby improving the turnover rate of tooling.
