Description

Technical Field

[0001] The utility model relates to the technical field of converter splash control, in particular to a converter splash control component. Background Art

[0002] Splashing is a common phenomenon in the top-blown converter blowing process. Various types of splashing may occur at any time without the operator's notice. The damage caused by splashing is relatively serious, increasing the consumption of steel materials and polluting the environment. With the large amount of splashing, the dephosphorization and desulfurization operations are affected, the heat loss increases, and the amount of molten steel changes, affecting the stability of smelting control. Severe splashing can also easily cause accidents, endangering the safety of personnel and equipment.

[0003] During the blowing process, the impact of the oxygen stream on the molten pool and the decarburization reaction produce a large amount of CO gas escaping, which inevitably causes the splashing of slag and molten metal. Under normal circumstances, the height of the molten metal splashing does not exceed the furnace mouth and will not form splashing, but the sudden decarburization reaction caused by the uneven decarburization of the molten pool will cause splashing.

[0004] The existing converters mostly collect splashes in a centralized manner, and the splashes are not controlled. Therefore, it is necessary to improve the converter during processing to avoid excessive splashes in the later stage that affect processing and production. Utility Model Content

[0005] The utility model aims to provide a converter splash control component to solve the problems raised in the above background technology.

The guide plate can limit the slag and metal liquid generated by the splashing, and the splashing slag and metal liquid are limited by the partition plates at the same time, so that the slag and metal liquid are limited and concentrated.

[0015] Preferably, a support block is welded to the bottom end surface of the mounting base, and there are four support blocks in total, and the four support blocks are distributed in a rectangular array relative to the mounting base. After the support blocks are installed on the foundation, the mounting base can be installed and supported.

[0016] Preferably, the guide plate is slidably sleeved in the fixed plate, and the guide plate is installed on the screw rod by means of threads. The guide plate is slidably sleeved in the fixed plate to limit the position, and after the limit, the guide plate is installed on the screw rod by means of threads, so that a person can open the driving mechanism to drive the screw rod to rotate, and the guide plate can be driven to move up and down according to the rotation direction of the screw rod.

[0017] Preferably, the gun body, gun tail and nozzle form an oxygen gun. The gun body, gun tail and nozzle form an oxygen gun, so that oxygen can be injected into the converter body.

[0018] Preferably, the guide block is sleeved on the frame, and the side end face of the guide block is installed on the output shaft of the hydraulic rod.

[0021] 2. The utility model provides a mounting frame, and when personnel are using the converter body, when personnel are supplying oxygen to the converter body through the oxygen lance composed of the gun body, the gun tail and the nozzle, the personnel are limited by sliding the guide plate in the fixed plate.

Therefore, the converter is circular, and the oxygen supply will overflow to the surroundings. Splashing is reduced by controlling the oxygen supply position, and splashing caused by direct oxygen supply impact is avoided, and then a control component is formed to control the splashing.
