Description

Technical Field

[0001] The utility model relates to the technical field of the skirt of a fume hood, in particular to a skirt of a movable fume hood of a converter. Background Art

[0002] The movable fume hood of a converter plays a crucial role in the steel smelting process, mainly responsible for collecting the fumes generated during the smelting of the converter. Since this process involves extremely high temperatures, the movable fume hood and its skirt are often in a high-temperature state. The long-term high-temperature environment will accelerate the wear of the equipment. Especially the skirt part is prone to water leakage and damage, which will not only affect the effective collection of fumes but also may bring serious safety risks.

[0003] Traditional fume hood skirts are usually constructed by continuous welding. This is prone to tearing or cracking at the weld due to thermal expansion and contraction of materials at high temperatures. In addition, the friction between the skirt and the furnace bottom will also exacerbate the problems of wear and water leakage. To solve these problems, the new design optimizes the welding structure of the closely spaced pipes, changing from full welding to intermittent welding to reduce thermal stress. At the same time, the diameter of the lower header of the movable fume hood skirt is adjusted to reduce the friction with the furnace bottom, and the connection bolt holes of the flange surface are adjusted to adapt to the deformation that may occur after long-term high temperatures. These improvements significantly improve the durability and reliability of the device, ensuring the smooth progress of the smelting process. Summary of the Utility Model
