Description

Technical Field

[0001] This utility model relates to steel ladles, specifically to steel ladles based on high thermoplasticity, corrosion-resistant high-aluminum, high-manganese steel. Background Technology

[0002] A ladle, also known as a steel container or molten steel ladle, is a container specifically designed to hold molten steel. It plays an important role in the steelmaking system, primarily used for storing and transporting molten steel, and sometimes also used in secondary steelmaking.

[0003] Patent application number 201220536370.3 discloses a metallurgical auxiliary device, specifically a ladle insulation cover release device. It includes: a ladle (1) lifted or moved by a crane, a ladle support bracket (2), and a crane hook (6). The device is characterized by further including: a ladle cover side hanger (3), an insulation cover (4), a lifting ring (5), a release cover hanger (7), and a support beam (11); wherein the ladle cover side hanger (3) is welded to the side of the insulation cover (4), and the release cover hanger (7) is inserted into or detached from the lifting ring (5) on the insulation cover (4) by the movement of the ladle (1).

[0004] The aforementioned patent achieves hoisting through the lifting lugs on the side wall of the ladle and the hook of the crane. However, it lacks a locking structure, which cannot guarantee the posture of the ladle during hoisting, making it prone to shaking and posing a danger. Secondly, existing ladles use a tilting method to pour out molten steel, but this method is less safe when pouring into the middle ladle. Utility Model Content

[0005] In view of the shortcomings of existing technologies, steel ladles do not have a locking structure during hoisting, which can easily cause them to sway and lead to danger. This utility model provides a steel ladle based on high thermoplasticity, corrosion resistance, high aluminum and high manganese steel.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] The ladle, based on high thermoplasticity, corrosion resistance, high-aluminum, and high-manganese steel, includes a ladle body with an inner cavity. A U-shaped lifting frame for hoisting is rotatably mounted on the ladle body. A water inlet penetrating the ladle body is located at the bottom of the inner cavity, and a plug is installed inside the inner cavity. The plug is slidably connected to the outer wall of the ladle body via a connector. Two vertically rotating U-shaped limiting frames are rotatably mounted on the top of the ladle. When the lifting frame is in the vertical position, the limiting frames rotate so that the lifting frame is located within the opening of the limiting frames and is limited. The side wall of the ladle is also equipped with a lever-type pulling structure. The output end of the lever-type pulling structure is connected to the connector, and the input end of the lever-type pulling structure is equipped with a pull rope. The other end of the pull rope is connected to the lifting frame so that when the lifting frame is in the vertical position, the input end of the lever-type pulling structure is pulled upward to lock the connector and the plug. This solution incorporates a sprue to replenish molten steel to the lower ladle. Additionally, a lifting frame with limit switches is installed on the ladle to lock it vertically, preventing rotation relative to the ladle during hoisting and enhancing safety. Finally, a lever-type pulling structure drives the lifting and lowering of the blocking column to control the opening and closing of the sprue. A pull rope is also installed to tighten the lever-type pulling structure when the lifting frame is erected, ensuring the sprue remains closed and further improving safety during hoisting.

[0008] As a preferred embodiment, the lever-type pulling structure includes a hinge seat and a lever that is vertically rotatably mounted on the hinge seat. The outer end of the lever is the input end, the inner end of the lever is provided with a pull rod, the top of the pull rod is the output end, and the rotational connection point between the lever and the hinge seat is located between the output end and the output end.

[0009] Preferably, the lever has a ring with a pull rope threaded through it, and the two ends of the pull rope are fixed to the two sides of the hanger. The ring can be made into a detachable structure, such as by welding a screw to the ring, passing it through the lever, and locking it with a nut.

[0010] Preferably, the inlet is a tapered opening with a diameter that gradually decreases from top to bottom, and the bottom of the plug is a tapered head that matches the shape of the tapered opening. This structure increases the contact area between the plug and the inlet, improving the sealing performance of the sealing point.

[0011] Preferably, the top of the plug has a threaded section, and the connector includes a horizontal connecting frame. One end of the connecting frame has a U-shaped connecting fork, which is fitted onto the threaded section and locked to the plug by a nut.

[0012] Preferably, the connector also includes a slider and a vertical rod with steps and threads disposed on the slider. The other end of the connecting fork is provided with a mounting hole and is fitted onto the step on the vertical rod through the mounting hole and locked with a nut.

[0013] Preferably, the outer wall of the ladle is provided with a slide rail, the slider slides in cooperation with the slide rail, and the pull rod is hinged to the slider.

[0014] Preferably, the slider has an upper mounting platform and a lower mounting platform. The vertical rod is detachably connected to the upper mounting platform, and a mounting seat is detachably mounted on the lower mounting platform. The top end of the pull rod is hinged to the mounting seat. The two mounting platforms are used to install the vertical rod and the mounting seat.

[0015] Preferably, the upper and lower mounting platforms are vertically spaced apart. A vertical rod passes through the upper mounting platform and is locked by a locking device located at the gap between the upper and lower mounting platforms. The mounting base passes through the lower mounting platform and is locked by a locking device located at the gap between the upper and lower mounting platforms. A locking pin is also provided at the gap between the upper and lower mounting platforms, passing through the slider and inserting into the slide rail. The locking pin is used for a second locking mechanism, that is, it remains locked after the ladle is placed and the hanger is lowered until the hanger is fully lowered and manually confirmed before the locking mechanism is engaged and the sprue is opened to replenish molten steel to the lower layer.

[0016] Preferably, the ladle body includes an inner insulation layer and an outer reinforcing layer, the surface of which is coated with a high-temperature resistant and corrosion-resistant coating. This high-temperature coating protects the surface and prevents oxidation and corrosion of the ladle.

[0017] Compared with the prior art, the advantages of this utility model are as follows: This application sets a sprue to replenish molten steel to the lower ladle. In addition, a hanger is set on the ladle and a limit switch is set to lock the hanger in a vertical state to ensure that the hanger does not rotate relative to the ladle during the hoisting process, which improves the safety of the hoisting process. Finally, a lever-type pulling structure is set to drive the blocking column to raise and lower to control the opening and closing of the sprue. At the same time, a pull rope is set to pull up and lock the lever-type pulling structure when the hanger is erected to ensure that the sprue is in a closed state, thus avoiding the sprue being in a closed state during the hoisting process, thereby further improving the safety of the hoisting.

A water inlet 101 penetrating the ladle body 10 is provided at the bottom of the inner cavity, and a plug 50 is provided inside the inner cavity. The plug 50 is slidably connected to the outer wall of the ladle body 10 through a connector. Two vertically rotating U-shaped limiting frames are rotatably mounted on the top of the ladle. When the hanger 20 is in the vertical state, the limiting frames are rotated so that the hanger 20 is located in the opening of the limiting frames and is limited. The side wall of the ladle is also provided with a lever-type pulling structure 30. The output end of the lever-type pulling structure 30 is connected to the connector, and the input end of the lever-type pulling structure 30 is provided with a pull rope 40. The other end of the pull rope 40 is connected to the hanger 20 so that when the hanger 20 is in the vertical state, the input end of the lever-type pulling structure 30 is pulled upward to lock the connector and the plug 50. This solution uses a sprue 101 to replenish molten steel to the lower ladle. Additionally, a hanger 20 is installed on the ladle with a limit switch to lock it vertically, ensuring it does not rotate relative to the ladle during hoisting, thus improving safety. Finally, a lever-type pulling structure 30 drives the blocking column 50 to control the opening and closing of the sprue 101. Simultaneously, a pull rope 40 pulls the lever-type pulling structure 30 upwards and locks it when the hanger 20 is upright, ensuring the sprue 101 is closed. This prevents the sprue 101 from remaining closed during hoisting, further enhancing safety.

[0026] Preferably, the lever-type pulling structure 30 includes a hinge seat 302 and a lever 301 that is vertically rotatably mounted on the hinge seat 302.

[0027] Preferably, the lever 301 is provided with a ring, through which a pull rope 40 is threaded, with both ends of the pull rope 40 fixed to the two sides of the hanger 20. The ring can be configured as a detachable structure, such as by welding a screw onto the ring, passing it through the lever 301, and then locking it with a nut.

[0028] Preferably, the nozzle 101 is a tapered opening with a diameter that gradually decreases from top to bottom, and the bottom of the plug 50 is a tapered head that matches the shape of the tapered opening. This structure can increase the contact area between the plug 50 and the nozzle 101, and improve the sealing performance of the plug.

[0029] Preferably, the top of the plug 50 has a threaded section, and the connector includes a horizontal connecting frame 501. One end of the connecting frame 501 has a U-shaped connecting fork, which is fitted onto the threaded section and locked with a nut to connect to the plug 50.

[0030] Preferably, the connector also includes a slider and a vertical rod 502 with steps and threads disposed on the slider. The other end of the connecting fork is provided with a mounting hole and is fitted onto the step on the vertical rod 502 through the mounting hole and locked with a nut.

[0031] Preferably, a slide rail 601 is provided on the outer wall of the ladle, the slider slides in cooperation with the slide rail 601, and the pull rod 304 is hinged to the slider.

[0032] Preferably, the slider is provided with an upper mounting platform 602 and a lower mounting platform 603. The vertical rod 502 is detachably connected to the upper mounting platform 602, and a mounting seat is detachably provided on the lower mounting platform 603. The top end of the pull rod 304 is hinged to the mounting seat. The two mounting platforms are used to install the vertical rod 502 and the mounting seat.

The mounting seat passes through the lower mounting platform 603 and is locked by a locking member located at the gap between the upper mounting platform 602 and the lower mounting platform 603. A locking pin 604 is also provided in the gap between the upper mounting platform 602 and the lower mounting platform 603, passing through the slider and inserted into the slide rail 601. The locking pin 604 is used for a second locking, that is, to continue to lock when the hanger 20 is lowered after the ladle is placed, until the hanger 20 is completely lowered and manually confirmed, after which the locking is engaged and the sprue 101 is opened to replenish molten steel to the lower layer.

[0034] Preferably, the ladle body 10 includes an inner insulation layer and an outer reinforcing layer, the surface of which is coated with a high-temperature resistant and corrosion-resistant coating.
