Description

Technical Field

[0001] This utility model relates to the field of ladle baking equipment, and in particular to a rotary ladle baking equipment. Background Technology

[0002] A ladle heater is a device used to heat steel ladles. Ladle heating is one of the main steps in the steelmaking process. New ladles, after being constructed and before being filled with molten steel, require a heating process.

[0003] Existing fixed ladle ovens, with their fixed supports, can only bake ladles of the same type and height, and cannot adapt to various usage scenarios. Chinese patent CN211052507U provides a ladle oven that uses a lifting rod movably connected to one end of the equipment box. By moving the lifting rod up and down, the height of the ladle baking lid can be adjusted to accommodate ladles of different heights.

[0004] However, in this existing technical solution, the ladle baking cover can only move horizontally up and down and cannot rotate. For large steel plants, which have a variety of converters and refining furnaces, as well as a variety of ladle types, and many ladles that have been modified and expanded, the ladle baking cover can only move up and down, which limits its application scenarios and cannot meet the diverse needs of steel plants or adapt to various different scenarios. Summary of the Invention

[0005] The purpose of this invention is to provide a rotary ladle oven that can be adjusted according to different ladle heights. The ladle baking cover can move up and down and can be rotated open to adapt to various types and heights of ladles.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotary ladle baker includes a base, a rotary support assembly, a baking cover frame, and a baking heating assembly. The baking cover frame has a fixed pulley at one end and a ladle baking cover at the other end, with a fourth rotary connection point in the middle. A burner is connected to the ladle baking cover, and a ladle is placed below the cover. The rotary support assembly includes a hydraulic rod, a rotary bracket, and a winch. One end of the rotary bracket is rotatably connected to the base, and the other end is rotatably connected to the fourth rotary connection point of the baking cover frame. One end of the hydraulic rod is rotatably connected to the base, and the other end is rotatably connected to the side of the rotary bracket near the fourth rotary connection point. The winch is fixedly connected to the base, and its wire rope is fixedly connected to the hydraulic rod after passing over the fixed pulley. The baking heating assembly includes a combustion air blower, a combustion air duct, and a gas duct. The combustion air blower is fixedly connected to the base. The outlet of the combustion air blower is connected to one end of the combustion air duct, and the other end of the combustion air duct is connected to the burner. The combustion air duct is used to supply combustion air to the burner. One end of the gas duct is connected to the burner, and the other end of the gas duct supplies gas to the burner.

[0008] As a preferred embodiment, the three connection points of the rotating bracket, the hydraulic rod, and the base, which are rotatably connected to each other, are located on the same vertical plane.

[0009] As a preferred embodiment, the rotating support is in the shape of a long rod.

[0010] As a preferred option, a butterfly valve is installed on the combustion air duct.

[0011] As a preferred embodiment, the middle portion of the combustion air duct is fixedly attached to the rotating support rod.

[0012] As a preferred embodiment, the baking cover frame has a support arm on one side of the fourth rotation connection point and a steel ladle baking cover on the other side, with the fixed pulley located at the end of the support arm away from the fourth rotation connection point.

[0013] As a preferred embodiment, the angle between the support arm and the ladle baking cover is an obtuse angle.

[0014] As a preferred embodiment, one end of the support arm is fixedly connected to a stabilizing component, and the other end of the stabilizing component is fixedly connected to the ladle baking cover.

[0015] As a preferred embodiment, the base is provided with multiple supports, which are respectively connected to the rotating bracket, the hydraulic rod, and the combustion fan.

[0016] The beneficial effects of this utility model are:

[0017] The above technical solution utilizes a rotating support assembly to move the ladle baking cover vertically. Simultaneously, a winch works in conjunction, allowing the baking cover to rotate around the fourth rotating connection point, accommodating ladles of different shapes and heights. The hydraulic rod and winch work together to securely fix the baking cover, ensuring stable operation. Combustion air and coal gas are delivered through gas and combustion air pipelines and mixed at the burner, achieving complete combustion and ideal baking results. A butterfly valve in the combustion air pipeline controls the flow rate. The shape and structure of the baking cover frame further enhance stability during operation. Attached Figure Description

Specifically, the winch 4 is fixedly set on the base 1, and the rotating bracket 3 in the rotating support assembly is in the shape of a long rod, with one end rotatably connected to the base 1. A bracket support can be set on the base 1, and the base 1 is rotatably connected to the rotating bracket 3 through the bracket support. The connection position is the first rotating connection point 15, and the rotating bracket 3 rotates around the first rotating connection point 15 as the axis.

[0024] One end of the hydraulic rod 2 is rotatably connected to the base 1. A hydraulic rod support can be provided on the base 1, and the base 1 is rotatably connected to the hydraulic rod 2 through the hydraulic rod support. The connection point is the second rotational connection point 16, and the rotating bracket 3 rotates around the second rotational connection point 16. The other end of the hydraulic rod 2 is rotatably connected to the rod part of the rotating bracket 3, and the connection point is the third rotational connection point 17. The hydraulic rod 2 can rotate around the third rotational connection point 17. The first rotational connection point 15, the second rotational connection point 16, and the third rotational connection point 17 are located in the same vertical plane and form a triangle. By extending and shortening the hydraulic rod 2, the rotation and fixation of the hydraulic rod 2 and the rotating bracket 3 can be achieved.

[0025] The baking cover frame includes a support arm 13, a fixed pulley 6, a ladle baking cover 5, a burner 11, and a stabilizer 14. Specifically, the burner 11 is mounted on the ladle baking cover 5, and the ladle 12 is placed below the ladle baking cover 5.
