Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of continuous casting equipment, relates to a guide plate of a continuous casting machine sector, and specifically is a slag water flushing device for a guide plate of a continuous casting machine sector. Background Art
[0002] The part of the continuous casting machine that deflects the billet from vertical to horizontal is the fan-shaped segment. The fan-shaped segment is an important part of the continuous casting machine production process. Its main function is to guide the billet pulled out from the supporting guide segment to prevent the billet shell from bulging and deformation under the static pressure of molten steel. The fan-shaped segment also has the function of guiding, transporting and clamping the ingot rod for pouring and billet drawing. The fan-shaped segment includes fan-shaped segment one, fan-shaped segment two, fan-shaped segment three and fan-shaped segment four from top to bottom. A group of guide plates are arranged between the upper and lower rollers on the outside of each pair of rollers at the outlet of each fan-shaped segment. The function of the guide plates here is to guide, support and restrain the billet. During the continuous casting production process, the iron oxide scale shed from the billet will accumulate on the guide plates to form scabs and lumps. If these scabs and lumps are not cleaned in time, they will leave scratches on the billet and affect the quality of the billet. Traditional continuous casting equipment is unable to clean the scabs and lumps on the guide plates in real time during operation. This work needs to be done specifically during equipment inspection and maintenance, which prolongs the downtime and reduces production efficiency. Utility Model Content
