Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust suppression nozzles, in particular to a dust suppression nozzle for a high-speed wire rod rolling mill. Background Technique
[0002] During the rolling process of the rolled piece of a high-speed wire rod rolling mill, due to the oxidation reaction between Fe in the rolled piece and O2 in the air at high temperature, products such as FeO, Fe2O3, and Fe3O4 are generated. Secondly, there are also red smoke dust generated by the scale powder, dust, and sludge in the roll turbidity ring cooling water when encountering the high-temperature rolled piece. The red smoke dust has a very bad impact on the surface pollution of on-site equipment and the health of on-site operators. However, currently, axial flow fans, dust removal guides, organized bag dust removal, etc. are respectively used for treatment. Using an axial flow fan only quickly dilutes the red smoke dust into the on-site environment, and its effect is poor. Using a dust removal guide will form uneven strong cooling on the rolled piece. Due to the slow speed of the rolled piece in rough and intermediate rolling, black marks will be formed in severe cases, resulting in a large temperature difference on the surface of the rolled piece and affecting the instability of the mechanical properties of subsequent finished products. Therefore, we propose a dust suppression nozzle for a high-speed wire rod rolling mill. Content of the Utility Model
