Description

Technical Field

[0001] The utility model relates to the technical field of steel production, in particular to an emergency alloy feeding device for a converter. Background Art

[0002] During the production process in a steel plant, alloys need to be fed into a converter for processing. Currently, in steel plants, usually two sets of converters share one set of alloy feeding system. The alloy is transported from a low-level bin to a middle-level bin through facilities such as a motor vibrating feeder, a large-inclination belt, a transfer station, and a belt distributing vehicle, and then is supplied to the converter through a feeding system.

[0003] In the above feeding system, due to the large number of operation links, when one of the devices fails, it will greatly affect the alloy feeding efficiency and even lead to a full-line production stop. Content of the Utility Model

[0004] The purpose of the utility model is to provide an emergency alloy feeding device for a converter, which is used to solve the problems that in the existing design, two sets of converters share one set of alloy feeding system, and due to the large number of operation links in the feeding system, when one of the devices fails, it will greatly affect the alloy feeding efficiency and even lead to a full-line production stop.

[0005] To achieve the above purpose, the utility model provides an emergency alloy feeding device for a converter, which is installed at the upper end of the converter. It is characterized by including:

[0006] A hoisting crane, which is slidably installed on a sliding track arranged at the upper end of the converter. A hanging hook is suspended at the bottom of the hoisting crane, and the hanging hook is used for hanging a ton bag containing alloy.

[0007] A feeding pipe group, including a blanking pipe and a distributing pipe. A receiving hopper is installed at the top inlet end of the blanking pipe, and a distributing joint is installed at the bottom of the blanking pipe. A plurality of the distributing pipes are connected to the corresponding distributing outlets of the distributing joint in a butt joint manner, and the bottom of the distributing pipe is aligned with the upper inlet of the corresponding converter.

[0008] As a further scheme of the utility model, the distributing joint is of a three-way structure and is provided with two distributing outlets.

[0009] As a further scheme of the utility model, the opening and closing of the distributing outlets of the distributing joint are controlled by an electric control module.

[0010] As a further scheme of the utility model, a crushing device is arranged on the receiving hopper, and the crushing device is used for crushing the ton bag.

[0011] Compared with the prior art, the utility model enables alloy materials to be hoisted by using the existing overhead lance crane traveling crane of the converter, and the alloy materials are conveyed into the corresponding converter through the feeding pipe group, so as to cooperate with the existing alloy feeding system to supply alloy materials for the tapping of the converter and avoid production interruption. Description of the Drawings

[0014] The technical solutions of the utility model will be further described in detail below in conjunction with the detailed embodiments.

[0015] As Figure 1 shown, in an embodiment of the utility model, an emergency alloy feeding device for a converter is installed at the upper end of the converter 6, and is characterized by comprising:

[0016] A hoisting traveling crane 1, which is slidably installed on a sliding track arranged at the upper end of the converter 6. A lifting hook is suspended at the bottom of the hoisting traveling crane 1, and the lifting hook is used for hanging a ton bag containing alloy.

[0017] A feeding pipe group, including a feeding pipe 3 and a branching pipe 5. A material receiving hopper 2 is installed at the top inlet end of the feeding pipe 3, and a branching joint 4 is installed at the bottom of the feeding pipe 3. A plurality of groups of branching pipes 5 are connected to the corresponding branching outlets of the branching joint 4 in a butt joint manner, and the bottom of the branching pipe 5 is aligned with the upper inlet of the corresponding converter 6.

[0018] The branching joint 4 is of a tee structure and is provided with two branching outlets.

[0019] The opening and closing of the branching outlets of the branching joint 4 are controlled by an electric control module.

[0020] A crushing device is provided on the material receiving hopper 2, and the crushing device is used for crushing the ton bag.

[0021] Specifically, in the utility model, when the existing feeding system fails and stops operating, the alloy is transported to the high-span platform of the converter 6 in ton bags according to varieties. The hoisting traveling crane 1 hoists the ton bag and drops it above the material receiving hopper 2. The bag-breaking device on the material receiving hopper 2 automatically breaks the ton bag, controls the feeding speed, and the alloy is loaded into the material receiving hopper 2 and then enters the material bins of different converters 6 through the feeding pipe 3 with a special angle of local treatment by means of a special tee branching device controlled by an electric control module, so as to adjust the molten steel composition during the tapping of the converter 6.

[0022] Compared with the prior art, the utility model enables the alloy materials to be hoisted by the overhead transfer gun crane traveling of the existing converter 6 at a high position, and the alloy materials are conveyed into the corresponding converter 6 through the feeding pipe group, so as to cooperate with the existing alloy feeding system to supply alloy materials for the steel tapping of the converter 6 and avoid production interruption.

[0023] The above describes the preferred embodiments of the utility model in detail. However, the utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the utility model within the knowledge scope of those of ordinary skill in the art.
