Description

Technical Field

[0001] The invention relates to the technical field of comprehensive collection and utilization machinery for metallurgical waste slag, and in particular to a converter split box-type slag cleaner and a working method thereof. Background Art

[0002] In the converter smelting production line of metallurgical enterprises, there are rails under the furnace for transporting slag to fill the car. During the converter smelting process, slag is poured, and most of the steel slag will be poured into the slag basin of the slag car, but the steel slag often splashes onto the rails under the furnace. A slag cleaner is installed at the front of the slag car, and the accumulated slag is cleaned synchronously during the operation of the slag car. Converter steelmaking slag is a solid waste generated in the steelmaking process. It consists of slag and furnace gas, etc. It is usually regarded as a waste, but it is actually a recyclable resource. The recycling of converter steelmaking slag includes two aspects: 1) Internal recycling: Steel slag is used as a raw material for sintering ore and a return material for steelmaking within the steel enterprise. This utilization method can directly participate in the steel production process, which helps to reduce production costs and improve resource utilization efficiency. External recycling: Steel slag is used in building materials, highway construction, agriculture and other fields. For example, steel slag can be used to produce building materials such as cement and concrete, or for road infrastructure construction. In addition, some components in steel slag are beneficial to soil improvement and plant growth. At the same time, recycling converter steelmaking slag can also reduce steelmaking costs and reduce environmental problems such as land pollution.

[0003] The existing slag cleaner has the following problems: during operation, when there is a lot of slag accumulation, the resistance of the slag cleaner is large, and the slag car is easily subjected to a relatively large impact during operation, causing damage to the slag cleaner's lifting lugs, body and other devices, or causing impact damage to the slag car's reducer motor and other devices. Currently, there is no device with a relatively reasonable design that can reduce the resistance or impact of the slag cleaner.

[0004] The existing slag cleaner has the following three prominent problems:

[0005] 1. Spare parts consumption remains high:

[0006] (1) The slag is not pushed in time or thoroughly, causing the slag to burn the rails (a set of rails under the furnace must be replaced every quarter);

[0007] (2) The amount of slag is large, the slag cleaner is rigidly welded to the slag car, and the forced pushing frequently burns out the slag car motor and reducer (the slag car motor and reducer are replaced one each quarter);

[0008] (3) The slag cleaner should be replaced frequently due to the high heat and resistance (one set should be replaced every quarter);

[0009] (4) Due to incomplete slag cleaning, production failures such as steel slag burning off or breaking the slag truck cable occurred on average once a month. The cost of spare parts remained high.

[0010] 2. The maintenance process consumes a lot of manpower and material resources: it takes 6 people about 12 hours to replace the under-furnace rails, and it takes 3 people 2 hours to replace the slag car cable. Frequent shutdowns restrict the improvement of converter production efficiency.

[0011] 3. The labor intensity of employees is high: the slag car slag cleaner does not clean the slag thoroughly, and two furnace workers are required to go to the furnace to manually clean the slag on both sides for every three furnaces of steel.

[0012] Therefore, there is an urgent need to design a converter split box-type slag cleaner and a working method to solve the current problems of high spare parts consumption, high maintenance and cleaning labor intensity, and low efficiency of the slag cleaner. Summary of the invention
