Description

Technical Field

[0001] The utility model relates to the technical field of molten iron ladles, in particular to a Y-shaped spheroidizing pre-set block for molten iron ladles. Background Art

[0002] When using refractory bricks to build the ladle, the refractory bricks are piled up in a "one" shape at the bottom of the ladle as a dam, and the bottom of the ladle is artificially divided into two parts. The gap between the refractory bricks is filled and smoothed with refractory paint. The small part is used as a spheroidizing pool. When in use, the spheroidizing agent, inoculant, covering agent, etc. are placed in the spheroidizing pool.

[0003] In the prior art, the service life of the dam of the spheroidizing pool is limited due to the problems of small blocks of refractory bricks, insufficient strength of refractory bricks, poor adhesion of refractory coatings, poor flatness of artificial brickwork, etc. In addition, after repeated use, the refractory bricks have the problem of falling off and dissolution. At the same time, due to the poor overall flatness of the dam, it also affects the contact between the molten iron and the spheroidizing agent and the inoculant, and affects the inoculation and spheroidization effect of graphite. Therefore, it is urgent to design a Y-shaped spheroidizing pre-set block for the molten iron ladle that is durable and can improve the inoculation and spheroidization effect of ductile iron castings. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art that refractory bricks may fall off and dissolve after repeated use, and the overall flatness of the retaining dam is poor, and a Y-shaped spheroidizing pre-set block for a molten iron ladle is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A Y-shaped spheroidizing prefabricated block for a ladle comprises a prefabricated block body and a ladle body. The prefabricated block body is in a Y-shaped structure. The prefabricated block body is fixedly installed on the inner bottom of the ladle body and divides the bottom of the ladle body into three parts, two of which are set as spheroidizing pools.

[0007] As a further technical solution of the utility model, the prefabricated block body is cast by heat-resistant material.

[0008] As a further technical solution of the utility model, the two sides on the bottom of the prefabricated block body are respectively set as a lower end surface and an upper end surface, and the width of the upper end surface is smaller than the width of the lower end surface.

[0009] The beneficial effects of the utility model are:

[0010] By setting up the pre-set block body, after high-temperature sintering and hardening, the molten iron impact resistance is greatly enhanced, thereby increasing its service life as a dam. The surface of the pre-set block body is flat and smooth. After encountering molten iron impact, the surface is not easy to fall off. The prefabricated block body has a Y-shaped structure and can form two spheroidizing pools in the ladle body. The same or different types of spheroidizing agents, inoculants, and covering agents can be placed, which greatly improves the inoculation and spheroidizing effects of ductile iron castings.

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] Please refer to the attached Figure 1 -Attached Figure 3 A Y-shaped spheroidizing pre-set block for a ladle comprises a pre-set block body 1 and a ladle body 2. The pre-set block body 1 is in a Y-shaped structure. The pre-set block body 1 is fixedly installed at the bottom of the ladle body 2, and the bottom of the ladle body 2 is divided into three parts, two of which are set as spheroidizing pools 3. The pre-set block body 1 is set by the device, and is sintered and hardened at high temperature, and its resistance to molten iron impact is greatly enhanced, thereby improving its service life as a dam. After the pre-set block body 1 is formed, the surface is flat and smooth. After encountering molten iron impact, the surface is not easy to fall off. The pre-set block body 1 is in a Y-shaped structure, and two spheroidizing pools can be formed in the ladle body 2. The same or different types of spheroidizing agents, inoculants, and covering agents can be placed, which greatly improves the inoculation and spheroidization effects of ductile iron castings.

[0019] Please refer to the attached Figure 1 and attached Figure 2 In a preferred embodiment, the prefabricated block body 1 is cast with a heat-resistant material, and the two sides of the bottom of the prefabricated block body 1 are respectively set as a lower end face 4 and an upper end face 5, and the width of the upper end face 5 is smaller than the width of the lower end face 4. When the prefabricated block body 1 is in use, the upper end face 5 is installed upward. Since the upper end face is a narrow mouth face, when the molten iron is injected, it can better guide the molten iron to flow into the spheroidizing pool 3 to react with the inoculant and the spheroidizing agent. After the prefabricated block body 1 is cast with the narrow mouth face upward, no molten iron residue will be generated in the ladle body 2.

[0020] Working principle: When in use, first assemble the mold, and the corresponding mold parts are fastened by bolts and nuts. After the assembly is completed, the mold has a wide upper mouth and a narrow lower mouth, which is convenient for subsequent demoulding. Then add the mixed heat-resistant material into the mold, and wait for the air in the mold and the heat-resistant material to be exhausted, and solidify by spontaneous combustion. The prototype of the prefabricated block body 1 is formed in the mold, and then the prefabricated block body 1 and the preset block mold are heated together, and dried. After the prefabricated block body 1 is sintered, hardened, and cooled to room temperature at high temperature, demoulding is carried out. When the ladle body 2 is built, the refractory bricks at the bottom of the ladle body 2 are laid in place first, and then the preset block body 1 is placed, and then the remaining building process is completed. The wide mouth surface of the preset block body 1 is in contact with the bottom of the ladle body 2, and the narrow mouth faces upward.

[0021] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
