Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a burner fixing structure for continuous casting and rolling production. Background Art

[0002] A vertical furnace refers to an ultra-high-power electric arc furnace with an upright furnace body and a vertical shaft on the furnace cover. The high-temperature exhaust gas discharged from the electric arc furnace is used to preheat scrap steel in the vertical shaft. The furnace gas moves upward in the furnace and exchanges heat with the charge in countercurrent. The charge in most vertical furnaces is in direct contact with the fuel. The outer layer of the furnace body of the vertical furnace used for copper smelting is a steel shell, and the inner lining is built. There is a water cooling box in the lining of the high-temperature zone in the lower part of the furnace body, and a number of burners are arranged radially in the upper part of the high-temperature zone. The burners are used to continuously heat the vertical furnace. The burners in the existing technology are to drill a mounting position in the outer steel shell, and then fix the relative position of the burners by the inner lining. When used for a long time, the burners will become loose, and there is a risk of falling and leaking. The lining needs to be repaired during maintenance, which reduces the utilization rate of the equipment. At the same time, impurities will fall into the furnace during the repair.

[0003] Publication No. CN 216770142 U discloses a vertical furnace burner flame holder. A second flange is installed by screwing bolts inward from the exterior of the vertical furnace. A second tube body is also fixed to the exterior of the vertical furnace using bolts. This ensures stable installation of the burner and second tube bodies and facilitates maintenance. The first flange rigidly seals the outer edges of the burner and second tube bodies, ensuring a seal. This avoids the use of traditional sealing measures such as sealants and mud to prevent contamination of materials within the vertical furnace, extending the device's service life. Furthermore, the device is suitable for high-temperature operating conditions. However, this patent has the following problems in actual use:

[0004] The vertical furnace burner flame holder is installed by screwing bolts inward from the outside of the vertical furnace to install the second flange, and at the same time, the second tube body is fixed with bolts on the outside of the vertical furnace to ensure that the burner and the second tube body are installed in a stable position. However, the bolt installation method is prone to bolt corrosion. Once the bolts are rusted, the installation and removal of the flange will be affected, thereby affecting the removal of the burner. At the same time, the removal by screwing the bolts is not only cumbersome, but also affects the efficiency of the installation and removal of the burner.

[0005] Therefore, a burner fixing structure for continuous casting and rolling production is proposed to solve the above-mentioned problems. Utility Model Content
