Embodiment Construction
[0020] A large-scale steel ladle hot repair tipping position dust removal method, the specific steps and parameters are as follows:
[0021] 1. According to the running track of the hot flue gas generated during the hot repair of the sliding nozzle, set the sliding nozzle dust cover 1 above the sliding nozzle side, set the sliding nozzle dust removal electric valve 4 on the sliding nozzle dust removal pipeline 2, and finally the sliding nozzle dust removal pipeline 2 Access to the dust collection system.
[0022] 2. According to the running track of the flue gas generated by the heat of the ladle cover during the hot repair of the ladle, an electric mobile dust removal cover car 3 is installed above the ladle cover side, and an electric valve 5 and a telescopic cover car are installed on the dust removal pipe 8 of the mobile dust removal cover car. The sleeve pipe 7 and the dust removal pipe 8 of the mobile dust removal hood vehicle are finally connected to the dust removal sy...

The invention relates to a de-dusting method for a hot repairing tipping position of a large-scale steel ladle and belongs to the technical field of converter steelmaking. The method comprises the following steps: arranging a sliding nozzle de-dusting cover above a sliding nozzle side; arranging a sliding nozzle de-dusting electric valve on a sliding nozzle de-dusting pipeline; connecting the sliding nozzle de-dusting pipeline with a de-dusting system; arranging an electric moving de-dusting cover vehicle above a steel ladle cover side; arranging an electric valve of a moving de-dusting cover vehicle and a telescopic sleeve on a de-dusting pipeline of the moving de-dusting cover vehicle; connecting the de-dusting pipeline of the moving de-dusting cover vehicle with the de-dusting system; in a hot repairing operation process of the steel ladle, hanging the steel ladle onto a steel ladle hot repairing tipping platform and driving the electric moving de-dusting cover vehicle to a de-dusting waiting position; after tipping and placing the steel ladle, driving the electric moving de-dusting cover vehicle to a de-dusting working position; opening the sliding nozzle de-dusting electric valve and the electric valve of the moving de-dusting cover vehicle in turn, thereby de-dusting. The de-dusting method has the advantages that hot exhaust gas can be effectively prevented from overflowing, the de-dusting effect can be guaranteed and the energy conservation of the de-dusting system can be achieved.
Description
technical field [0001] The invention belongs to the technical field of converter steelmaking, and in particular relates to a large-scale steel ladle hot repair tipping position dust removal method. The invention is suitable for the tipping position of large-scale steel ladle hot repair in the iron and steel industry, and collects the dust-containing smoke generated during the hot repair and baking of the steel ladle. Background technique [0002] In the process of converter steelmaking, the ladle is an indispensable molten iron guiding equipment, which is used very frequently, and the maintenance of the ladle is very important. Ladle hot repair tipping position During the ladle hot repair and baking process, a large amount of smoke and dust will be generated. With the increasingly stringent national environmental protection policies and occupational hygiene standards, the working environment of the ladle hot repair tipping position will be improved to prevent smoke and dust ...
