Description

Technical Field

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

[0002] In the converter smelting production line of metallurgical enterprises, there are tracks under the furnace for transporting slag ladle cars. During the converter smelting process, when pouring slag, most of the steel slag will be poured into the slag basin of the slag car, but it often happens that the steel slag splashes onto the tracks under the furnace. A slag cleaner is installed in the front of the slag car to clean the accumulated slag synchronously during the operation of the slag car. Converter steelmaking slag is a solid waste generated during the steelmaking process. It consists of slag and furnace gas, etc., and 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: The steel slag is used as a raw material for sintered ore and a return material for steelmaking within the iron and steel enterprise. This utilization method can directly participate in the steel production process, helping to reduce production costs and improve resource utilization efficiency. External recycling: The steel slag is used in fields such as building materials, highway construction, and agriculture. For example, the steel slag can be used to produce building materials such as cement and concrete, or for road foundation construction. In addition, certain components in the steel slag are beneficial to soil improvement and plant growth. At the same time, recycling converter steelmaking slag can also reduce the steelmaking cost and environmental protection problems such as land pollution.

[0003] Existing slag cleaners have the following problems: During operation, when there is a large amount of accumulated slag, the resistance of the slag cleaner is large, and it is easy to cause a relatively large impact on itself during the operation of the slag car, damaging devices such as the lifting lugs and the body of the slag cleaner, or causing impact damage to the reducer motor of the slag car. Currently, there is no device with a relatively reasonable design that can reduce the resistance or impact of the slag cleaner.

[0004] Existing slag cleaners have the following three prominent problems:

[0005] 1. High spare part consumption:

[0006] (1) Delayed and incomplete slag pushing causes the steel slag to burn out the tracks (one set of tracks under the furnace needs to be replaced every quarter);

[0007] (2) With a large amount of slag, the slag cleaner is rigidly welded to the slag car, and frequent strong pushing burns out the motor and reducer of the slag car (one motor and one reducer of the slag car need to be replaced every quarter);

[0008] (3) The slag cleaner also needs to be frequently replaced due to being roasted and having a large resistance (one set needs to be replaced every quarter);

[0009] (4) Incomplete slag cleaning results in production failures such as the steel slag burning and hanging up the cable of the slag car, which occur on average once a month. The spare part cost remains high.

[0010] 2. The overhaul process consumes a large amount of manpower and material resources: It takes about 6 people 12 hours to replace the lower rail of the furnace, and 3 people 2 hours to replace the cable of the slag car. Frequent shutdowns restrict the improvement of the production efficiency of the converter.

[0011] 3. The labor intensity of workers is high: The slag cleaner of the slag car fails to clean the slag thoroughly. For every 3 heats of steel, two forehearth workers are needed to manually clean the accumulated slag on both sides under the furnace.

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

[0013] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a converter split box-type slag cleaner and its working method, aiming to overcome the difficulties such as large resistance impact and difficult maintenance of the current slag cleaner.

[0031] For the converter split box-type slag cleaner and its working method designed by the present invention, by setting the box body in a split manner, the wear-resistant cost is increased for split installation. When the box body is deformed or damaged, there is no need to replace the entire slag cleaner. Only the two side box bodies or the middle box body part needs to be replaced and then taken off the production line for repair, ensuring the maintenance efficiency during use and reducing the maintenance cost.

[0032] For the converter split box-type slag cleaner and its working method designed by the present invention, the device and equipment have the advantages of simple structure, convenient use and recyclability, and are simple and easy to implement, which is conducive to popularization.

[0058] A working method of a converter split box type slag cleaner includes the following steps:

[0059] 1. Assemble the slag cleaner. Select whether the middle box body 3 is needed according to the width of the slag truck. If the middle box body 3 is not needed, the first flange 1.2 is directly connected to the second flange 2.2, and the first box body 1 is connected to the second box body 2. If the middle box body 3 is needed, the first flange 1.2 is connected to the third flange 3.1, and the fourth flange 3.2 is connected to the second flange 2.2.

[0060] 2. Assemble the lifting lug mechanism 4. Insert the lifting lug connecting plate 4.1 of the lifting lug mechanism 4 into the first jack 1.11 or the second jack 2.10. Pass the pin shaft through the strip hole 4.2 to install the entire slag cleaner at the front of the slag truck. The guide wheel 4.4 of the lifting lug mechanism 4 rolls on the guide rail of the slag truck, and the guide wheel 4.4 assists the slag cleaner to move with the slag truck.

[0061] 3. During the slag loading and transporting work of the slag truck, push the slag cleaner forward. The slag retaining plate at the front pushes the steel slag forward until it runs to the steel slag collection place, shovels up and collects the steel slag that has fallen beside the collection guide rail, and collects it together with the steel slag in the slag truck.

[0062] 4. The collected steel slag is recycled to make cement or bricks.

[0063] The technical solution of the present invention has been comprehensively promoted and applied in 6 converters of the steelmaking plant, achieving good results, and clearing obstacles for the safe production, smooth operation of equipment, and cost reduction in the area under the converter:

[0064] 1. The track under the furnace is changed from being replaced quarterly to being replaced annually, saving 3 sets of tracks per converter per year.

[0065] 2. The motor and reducer of the slag truck are changed from being replaced quarterly to being replaced annually, saving 3 motors and 3 reducers of the slag truck per converter per year.

[0066] 3. The slag cleaner of the slag truck is changed from replacing one set quarterly to now regularly replacing the copper sleeve inside the idler roller, saving 3 sets of slag cleaners per converter per year.

[0067] 4. The cable of the slag truck is changed from replacing one set monthly to replacing one set quarterly, saving 9 sets of slag truck cables per converter per year.

[0068] The implementation of the results has solved the problem that maintenance workers frequently replace the track under the furnace, the motor and reducer of the slag truck, the slag cleaner of the slag truck, and the cable of the slag truck. The slag cleaning and maintenance class under the furnace has changed from a "fire brigade" to a "technical team" that studies reducing faults and discovers improvements. In addition, the slag cleaning of the slag truck is thorough, and the furnace front workers no longer need to manually clean the slag under the furnace. At the same time, the slag cleaning efficiency is improved, the collection efficiency of solid waste is increased, and the utilization rate of solid waste is higher.

[0069] The present invention is not limited to the above embodiments. Any person should know that structural changes made under the inspiration of the present invention, as long as they have the same or similar technical solutions as the present invention, all fall within the protection scope of the present invention.
