Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking, in particular to a high-precision converter blowing early stage slag material adding device. Background Art

[0002] Slag making is an essential part of the steel and iron making process. In order to reduce the impurities in steel, these impurities are separated and added to the slag. Since the slag has a light specific gravity and floats on the molten steel, it is easier to remove. In addition, the slag can protect the molten steel from direct contact with the atmosphere. Slag making is the process of adding steelmaking substances called slag-forming agents, such as calcium fluoride or calcium oxide, to form slag during the steelmaking process.

[0003] During steelmaking, slag-forming material needs to be added to the converter. Currently, the slag-forming material adding device can only add slag-forming material at a fixed point during use, and cannot add slag-forming material to different positions in the converter, which will affect the slag-forming effect of steelmaking and is not conducive to steelmaking work. Utility Model Content

[0004] The utility model aims to provide a high-precision slag-making material adding device for the early stage of converter blowing, which has the advantages of being able to add slag-making material to different positions in the converter, ensuring the slag-making effect of steelmaking, and solving the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-precision converter blowing early stage slag material adding device, comprising a support frame, a rectangular frame and an adding cylinder, a mounting plate is installed on the upper end of the support frame, a weighing sensor is arranged on the upper end of the mounting plate, a material box is arranged on the upper end of the weighing sensor, and a material discharge pipe is arranged on the lower end of the material box;

[0006] A symmetrically distributed support plate is installed at the upper end of the rectangular frame, a fixed plate is installed at the upper end of the support plate, a rotating shaft is rotatably installed at the lower end of the mounting plate, and the end of the rotating shaft is fixedly connected to the upper end of the fixed plate;

[0008] The adding cylinder is installed between the fixing rods, and the upper end of the adding cylinder is opened.

[0009] When using the high-precision converter blowing early stage slag material adding device of the utility model,

[0010] The utility model is arranged on one side of the converter, and the adding cylinder is located above the converter. Slag material is added into the material box. The amount of slag material in the material box can be detected by the weighing sensor. When slag material needs to be added, the solenoid valve on the discharge pipe is opened to discharge it from the discharge pipe into the adding cylinder. The weight detected by the weighing sensor will be reduced accordingly. When a certain amount of slag material in the material box is discharged, the solenoid valve on the discharge pipe is closed to facilitate the control of the amount of slag material added. Thereafter, the solenoid valve on the discharge pipe is opened to discharge the slag material from the discharge pipe into the converter. The threaded rod is rotated by the second driving device, and the adding cylinder can be driven to move left and right with the cooperation of the movable block. At the same time, the rectangular frame is rotated by the first driving device, and the slag material can be added to different positions in the converter.

[0011] Preferably, the feed pipe extends to below the mounting plate, and a solenoid valve is provided on the feed pipe.

[0012] Preferably, a first driving device is provided at the upper end of the mounting plate, and a main shaft of the first driving device is connected to the axis of the rotating shaft.

At the same time, the rotating shaft is rotated by the first driving device, so that the rectangular frame can be rotated, thereby making the adding barrel move in a circle. The slag-forming material can be added to different positions in the converter by coordinating the left and right movement of the adding barrel, thereby ensuring the slag-forming quality of steelmaking.
