Description

Technical Field

[0001] The present application relates to the field of industrial smelting, and in particular to a molten iron waste slag transfer system. Background Art

[0002] Hot metal transfer is a key step in the blast furnace smelting process, involving the safe and efficient transfer of molten iron from the ironmaking furnace to subsequent steel processing facilities (such as converters or casting equipment). The temperature of molten iron is extremely high, usually exceeding 1500°C, so specially designed high-temperature resistant containers and vehicles, such as iron tank trucks or pallet trucks, must be used during the transfer process. In addition to the main molten iron handling during the molten iron transfer process, the molten iron must also be deslaged to remove impurities and non-metallic inclusions, which is crucial to improving the quality of the final steel.

[0003] The handling and slag removal of molten iron involve high risks and technical requirements. Traditionally, slag removal is done manually by workers, who use long-pole tools to scrape slag from the surface of the molten iron. This operation relies on the workers' experience. Due to the high temperature characteristics of molten iron, any improper operation can easily lead to safety accidents, such as scalding caused by molten iron splashing. However, the existing slag removal platforms currently do not have any protective facilities. This lack of safety protection makes it very easy for workers to have accidents during operation, posing a serious threat to their lives. Summary of the invention

[0050] In order to better understand the technical solution of the present application, a specific example is provided below for illustration. The details listed in the example are mainly for ease of understanding and are not intended to limit the scope of protection of the present application.

[0051] The workflow of the molten iron waste slag transfer system of this application is as follows:

[0052] The worker first climbs onto the slag removal platform 3 via the stairs 2 and stands inside the protective cover 1 to operate. The guardrails 8 around the platform and stairs 2 are designed to prevent workers from accidentally falling and ensure the safety of the operation. The bracket on the platform is equipped with multiple installation grooves of different heights. The worker can adjust the position of the support roller 4 according to his height and install the support roller 4 on the appropriate groove.

[0053] When performing the slag removal operation, the worker places the slag removal rod on the support roller 4 and uses the support roller 4 as a fulcrum to reduce the force required for slag removal and improve the slag removal efficiency. The waste slag generated during the slag removal process will be thrown into the funnel 7, and the waste slag will smoothly fall into the waste slag bucket 602 through the funnel 7.

[0054] When the waste slag bucket 602 is full, the worker can push the waste slag transfer vehicle 601 and move it out of the work area with the help of the mobile platform 603. At this time, the waste slag in the waste slag bucket 602 can be poured into a designated waste slag treatment area using a forklift or a driving vehicle.

[0055] The entire workflow is not only efficient and orderly, but also ensures the safety of operators through multiple safety measures such as protective covers 1, guardrails 8, and reasonably configured support rollers 4. At the same time, the mechanized slag treatment method is used to reduce the intensity of manual labor and improve the operation efficiency. The design of this workflow takes into account the practicality and safety of the operation, making the molten iron slag transfer system more suitable for modern large-scale industrial production environments.
