Description

Technical Field

[0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a movable three-coordinate type mixing car tank mouth slag cleaning device and method, which is suitable for cleaning molten iron residue at the tank mouth during the use of the mixing car. Background Art

[0002] Molten iron transportation is one of the important links in steel production, and mixing cars are usually used to complete this task. During the transportation of molten iron, iron slag is often formed at the tank mouth of the mixing car due to the cooling and oxidation of the molten iron. These iron slags will not only reduce the effective volume of the tank car and affect the transportation efficiency of the molten iron, but may also form accumulation at the tank mouth, causing blockage of the tank mouth, affecting the flow and dumping of the molten iron, and even causing safety accidents in serious cases.

[0003] The traditional method of cleaning slag from the tank mouth of a mixing iron car mainly relies on manual operation, which is to use tools such as heavy hammers to knock the iron slag to make it fall. Some steel companies have also developed fixed slag cleaning machines, which use a base to fix the base and use a mechanical arm to drive a cutter disc to clean the slag from the tank mouth. However, manual cleaning and fixed slag cleaning methods have the following disadvantages: (1) Manual slag cleaning methods are labor-intensive, have low cleaning efficiency, and pose great safety hazards; (2) Fixed slag cleaning devices are usually installed in a fixed position, with a limited range of motion and poor adaptability, making it difficult to adapt to complex slag cleaning conditions. (3) Fixed slag cleaning machines have poor flexibility and cannot meet multi-directional slag cleaning needs. Slag cleaning can only be carried out by using a mechanical arm to drive a cutter disc. Summary of the invention
