A ladle mechanism safety guard member

Abstract

This utility model discloses a safety protection component for a ladle mechanism, including a ladle body, a ladle mechanism, and a protective ring welded to the bottom of the ladle body. The protective ring consists of a main body, a middle part, and an extension, all welded to the bottom of the ladle body. A clearance is provided between the main body, the middle part, and the extension for clearance. A protective component for blocking large pieces of welding slag is welded between the main body and the middle part. The height of the protective component is less than the height of the protective ring and it is welded at the midpoint between the main body and the middle part. This utility model protects the ladle mechanism through the protective component, preventing large pieces of slag from getting stuck in the ladle mechanism during the operation of the converter tapping trolley. This prevents the slag from being pulled apart by the pressure of the slag against the ground, causing molten steel to spill onto the ground. This maintains the safety and stability of the ladle mechanism during production, extends its service life, ensures the safety of molten metal, and reduces abnormal ladle discharge.

Description

Technical Field

[0001] This utility model relates to the field of iron and steel metallurgy technology, and in particular to a safety protection component for a ladle mechanism. Background Technology

[0002] In the steel smelting process, ladles are used to hold and transport molten steel at high temperatures. A ladle mechanism is typically located at the bottom of the ladle to control its opening and closing for slag removal or pouring operations. However, in actual production, large pieces of welding slag or steel slag can easily fall into the gap between the ladle car's slag baffle and the ladle body. This welding slag may become stuck under the ladle mechanism.

[0003] As the ladle car moves or the ground rises, welding slag is compressed between the ladle mechanism and the ground, causing the mechanism panel to bear enormous lateral pressure. Under long-term action, this may lead to deformation of the ladle mechanism, breakage of tie rods, or even accidental opening of the ladle, causing molten steel leakage, seriously threatening production safety and equipment lifespan. Therefore, those skilled in the art provide a safety protection component for the ladle mechanism to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety protection component for a steel ladle mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A safety protection component for a ladle mechanism includes a ladle body, a ladle mechanism, and a protective ring welded to the bottom of the ladle body;

[0007] The protective ring consists of a main body, a middle part, and an extension part, all of which are welded to the bottom of the ladle body. A clearance for clearance is provided between the main body, the middle part, and the extension part.

[0008] A protective component for blocking large pieces of welding slag is welded between the main body and the intermediate part. The height of the protective component is less than the height of the protective ring and it is welded in the middle position between the main body and the intermediate part. The protective component blocks the large pieces of welding slag to prevent them from touching and squeezing the ladle mechanism.

[0009] As a further embodiment of this utility model, the protective component is a steel plate and is arc-shaped, with the arc being the same as that of the protective ring.

[0010] As a further improvement of this invention, the protective component is made by hot bending.

[0011] As a further embodiment of this utility model, the ladle mechanism includes two mechanism panels, which are symmetrically arranged and form an installation cavity in the middle. One end of each mechanism panel is welded to the inner wall of the main body and the other end extends to the outer side of the main body. A tie rod is hinged between the two mechanism panels.

[0012] As a further embodiment of this utility model, an argon gas connector is fixedly connected to the bottom of the ladle body.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, by welding a protective component to the bottom of the ladle body, the ladle mechanism is protected, preventing large pieces of slag from getting stuck in the ladle mechanism during the operation of the converter tapping trolley. This would prevent the slag from being pulled apart by the pressure of the ground, causing molten steel to spill onto the ground. This maintains the safety and stability of the ladle mechanism during production, increases its service life, ensures the safety of molten metal, and reduces abnormal ladle discharge.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0020] Reference Figs. 1-3A safety protection component for a ladle mechanism includes a ladle body 1, a ladle mechanism 2, and a protective ring 3 welded to the bottom of the ladle body 1. The protective ring 3 serves to support and protect the ladle body 1.

[0021] The protective ring 3 is composed of a main body 301, a middle part 302 and an extension part 303, all of which are welded to the bottom of the steel ladle body 1. A clearance 5 for avoiding gaps is provided between the main body 301, the middle part 302 and the extension part 303.

[0022] A protective component 6 for blocking large pieces of welding slag is welded between the main body 301 and the intermediate part 302. The height of the protective component 6 is less than the height of the protective ring 3 and it is welded in the middle position between the main body 301 and the intermediate part 302. The protective component 6 blocks the large pieces of welding slag to prevent them from touching and squeezing the ladle mechanism 2. This avoids the situation where large pieces of steel slag get stuck between the mechanism panel and the ground. As the ground rises, the squeezing pressure increases, which would cause the large pieces of steel slag and the ground to squeeze the ladle mechanism 2 apart, resulting in molten steel falling to the ground.

[0023] In this utility model, the protective component 6 is a steel plate and is arc-shaped, with the same arc as that of the protective ring 3. The steel plate has high strength and can withstand large pieces of steel slag.

[0024] In particular, the protective component 6 is made by hot bending, and the steel plate formed by hot bending is stronger.

[0025] It should be noted that the ladle mechanism 2 includes two mechanism panels 201, which are symmetrically arranged and form an installation cavity in the middle. One end of each mechanism panel 201 is welded to the inner wall of the main body 301 and the other end extends to the outer side of the main body 301. A tie rod 202 is hinged between the two mechanism panels 201. The ladle mechanism 2 is used to open the ladle body 1 for material discharge.

[0026] In this utility model, an argon gas connector 4 is fixedly connected to the bottom of the steel ladle body 1. The argon gas connector 4 is used to connect the argon gas pipeline on the trolley. This is an existing structure and will not be described in detail here.

[0027] Working principle: The steel plate is processed by hot working to form the protective component 6, which is then welded between the main body 301 and the intermediate part 302. When the ladle body 1 moves, the protective component 6 moves with it. When a large piece of steel slag near the edge of the ladle body 1 on the slag baffle plate of the ladle car falls from the gap between the slag baffle plate and the ladle body 1 during the process of the ladle car moving to the hoisting span after steel tapping, the protective component 6 prevents the large piece of steel slag from entering the bottom of the ladle mechanism 2. This avoids the large piece of steel slag getting stuck between the mechanism panel and the ground. As the ground rises, the increasing extrusion pressure causes the large piece of steel slag to pull the ladle mechanism 2 apart, resulting in the molten steel falling to the ground. This maintains the safety and stability of the ladle mechanism 2 in production, improves the service life of the ladle mechanism 2, ensures the safety of molten metal, and reduces abnormal ladle discharge.

[0028] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
