Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical converters, in particular to a device for replacing a slag-blocking slide plate at the rear of a converter. Background Art

[0002] A large amount of slag is produced in the converter during the metallurgical process. The slag stopper slide can prevent the slag from mixing with the molten steel or overflowing out of the furnace, thereby ensuring the purity and quality of the molten steel. However, due to the long-term wear of the slag and the slag stopper slide, the slag stopper slide needs to be replaced regularly to maintain its slag-blocking effect.

[0003] In the related technology, when replacing the slag stop slide, the furnace mouth needs to be shaken to an angle downward, which makes it impossible to fill the furnace mouth normally. The time for replacing the slag stop slide needs to be coordinated separately, which affects the continuity of work. In addition, the downward tilt of the furnace mouth will cause the loss of residual molten steel and scrap steel in the furnace. At the same time, when an emergency occurs where the slag stop slide cannot be opened, the entire furnace of molten steel needs to be poured out from the furnace mouth, resulting in the scrapping of the entire furnace of molten steel, a serious waste of steel resources, and a significant increase in production costs. Utility Model Content

[0004] The purpose of the present utility model is to provide a device for replacing a slag-blocking slide plate after a converter furnace, so as to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A device for replacing a slag-blocking slide plate after a converter furnace, comprising:

[0007] A bottom plate and a cover plate, wherein two first columns and two second columns are respectively provided between the four corners of the bottom plate and the four corners of the cover plate;

[0008] Guardrails are provided on both sides of the base plate, and both ends of the guardrails are connected to the first column and the second column on both sides respectively;

[0009] The second column is provided with a cavity, and a telescopic column is slidably provided in the cavity;

[0010] The second column and the telescopic column are respectively provided with pin holes.

[0011] The device for replacing the slag-blocking slide plate after the converter furnace according to this solution has at least the following technical effects:

[0012] The device for replacing the slag stop slide after the converter furnace is provided with a cavity in the second column, a telescopic column is slidably provided in the cavity, and the device is lifted onto the converter support ring by a forklift. During the lifting process, the telescopic column slides down vertically along the second column, so that the telescopic column extends out of the bottom of the second column and contacts the ground, and the telescopic column is fixed to the second column so that the telescopic column supports the device, so that the staff can climb up the device with a ladder to replace the slag stop slide after the converter furnace; the device replaces the original method of replacing the slag stop slide by tilting the furnace mouth downward, and replaces the slag stop slide after the converter furnace, thereby realizing synchronous operation with the furnace replenishment, and there is no need to coordinate the time of replacing the slag stop slide separately, thereby improving work continuity and convenience; at the same time, the device eliminates the need to shake the furnace mouth to tilt downward, and can handle the emergency situation where the slag stop slide cannot be opened by holding the furnace mouth upward, thereby avoiding the loss or scrapping of molten steel and scrap steel, effectively saving steel resources, improving resource utilization, and reducing production costs.

[0013] As a further solution of the present invention: the first column is solid square steel.

[0014] Since the first column is made of solid square steel, it can provide better structural stability for the device, enable the device to maintain strength and rigidity, prevent deformation or damage during use, ensure the stability and reliability of the device, and thus ensure the safety of the operator when replacing the slag stop slide after the converter furnace.

[0015] As a further solution of the present invention: the second column is a hollow square steel.

[0016] As a further solution of the present invention: the inner diameter of the telescopic column is adapted to the inner diameter of the second column.

[0017] Since the second column is hollow square steel, the telescopic column is adapted to the inner diameter of the second column, which facilitates the sliding assembly of the telescopic column in the second column of the hollow square steel. When the device is lifted by a forklift, the telescopic column can be extended along the bottom of the second column. The forklift lifts the bottom of the device onto the converter support ring, and the bottom of the telescopic column contacts the ground and fixes the telescopic column and the second column, so that the telescopic column supports the device, effectively improving the stability and reliability of the device, and making it convenient for staff to climb up the device via a ladder to replace the slag stop slide behind the converter.

[0018] As a further solution of the present invention: the device also includes a pin.

[0019] When the device is lifted by a forklift, the telescopic column extends along the bottom of the second column, and the pin shaft hole of the second column corresponds to the pin shaft hole of the telescopic column. The pin shaft passes through the pin shaft hole of the second column and the pin shaft hole of the telescopic column respectively, so that the telescopic column is fixed on the second column, thereby improving the supporting stability of the telescopic column to the device.

[0020] As a further solution of the present invention: a forklift hole is provided at the bottom of the base plate.

[0021] By providing a forklift hole at the bottom of the base plate, the fork of the forklift is inserted into the forklift hole to lift the device, thereby preventing the fork of the forklift from directly contacting the base plate of the device, preventing the base plate from being directly worn, and improving the service life of the base plate.
