Description

Technical Field

[0001] The invention relates to the technical field of clustered oxygen lance modules, in particular to a multifunctional clustered oxygen lance module. Background Art

[0002] The cluster oxygen lance reduces smelting costs, improves molten steel quality, and reduces workers' labor intensity during production; the principle of the cluster oxygen lance is to add an outer layer of surrounding accompanying flow around the traditional oxygen lance, so that the central supersonic jet expands and decays less, and the supersonic jet is longer. Improve the penetration depth and stirring intensity of the oxygen jet into the molten pool. At the same time, due to the delayed decay of the jet velocity, the blowing gun position of the oxygen lance can be increased without affecting the impact depth of the jet on the molten steel, which prolongs the service life of the oxygen lance nozzle. The main function of the furnace wall cluster oxygen lance is to strengthen electric furnace smelting, shorten smelting time, reduce smelting costs, improve molten steel quality, reduce workers' labor intensity, and improve the automation level of electric furnace smelting; with the popularization of ultra-high power electric furnaces, steel mills have higher and higher requirements for auxiliary smelting equipment, accelerating the internal heating rate of electric furnaces, shortening smelting time, reducing equipment use costs, reducing equipment daily maintenance costs, and increasing the safety performance requirements of equipment. A multifunctional cluster lance module is now proposed. The multifunctional cluster oxygen lance is no longer the traditional cluster oxygen lance. The traditional cluster oxygen lance only adds surrounding oxygen to the outer layer of the main oxygen. It is the simplest integrated oxygen lance. In the past, this oxygen lance could be used for small electric furnaces with a diameter of 20 tons and 30 tons. It could not be disassembled, and the copper head was easily damaged. Once damaged, it had to be replaced as a whole. It was highly energy-consuming. When in use, it would only react chemically with the gas inside the electric furnace, and there would be no flame beam visible to the naked eye. Due to the high energy consumption of small electric furnaces of 20 tons and 30 tons, new ones are not allowed in China at present. The multifunctional cluster oxygen lance is an ultra-high power cluster oxygen lance with the inner layer of main oxygen, the middle layer of epoxy, and the outer layer of fuel gas. When in use, the fuel gas and epoxy react chemically to produce a flame beam. The flame beam can extend from the nozzle of the cluster oxygen lance to a distance of 1-1.5 meters inside the electric furnace before it will diverge. For electric furnaces above 50 tons, especially those above 100 tons, the furnace body diameter is large, and the traditional cluster oxygen lance has become useless and cannot be used. The addition of gas can make the furnace burn more intensely, heat up faster, and shorten the smelting time. This time, the main focus is on the development of a multifunctional furnace wall cluster oxygen lance module, which integrates the copper water tank and the ultra-high power cluster oxygen lance. The module can penetrate deeper into the electric furnace. The depth of the oxygen lance plus the original 1-1.5 meter flame beam allows the flame beam to reach a position of 1.5-2 meters. All major components can be replaced to extend the service life and reduce the cost of use.

[0003] The existing multifunctional cluster oxygen lance module has the following problems:

[0004] 1. The furnace wall oxygen lance for steel-making electric furnace is generally fixed in the copper water tank. The installation of the copper water tank requires digging a large rectangular hole in the water-cooling plate of the furnace wall, and the copper water tank is placed in the large hole and fixed. In order to have enough space to install the furnace wall oxygen lance, the copper water tank is relatively large in size, and the cost of raw materials is high. In addition, when in use, the surface area is large, which is very susceptible to erosion by molten steel and crushing by large pieces of furnace charge. Once one point is damaged, the copper water tank will not be able to continue to be used, and the furnace wall oxygen lance will also be unable to be used, affecting the continuity of the steelmaking process, and the subsequent repair and maintenance costs are also very high.

[0005] 2. The copper water tank is constrained by the furnace wall, the conditions inside the furnace and the oxygen gun on the furnace wall and cannot go too deep into the furnace. Affected by this, the oxygen gun cannot go too deep into the furnace. The airflow ejected by the oxygen gun decays with distance, and the effective utilization rate decreases. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a multifunctional clustered oxygen lance module, which solves the problem that the copper water tank is very susceptible to erosion by molten steel and crushing by large pieces of furnace charge due to its large surface area. Once one point is damaged, the copper water tank cannot be used any more, and the furnace wall oxygen lance cannot be used any more, thus affecting the continuity of the steelmaking process. In addition, the copper water tank is constrained by the furnace wall, the conditions inside the furnace, and the furnace wall oxygen lance, and cannot penetrate too deep into the electric furnace. As a result, the oxygen lance cannot penetrate too deep into the electric furnace, and the airflow ejected by the oxygen lance decays with distance.
