Edge shielding device for sheet and strip steel cooling control system

Abstract

The invention provides an edge shielding device for a sheet and strip steel cooling control system, and belongs to the technical field of rolling control and cooling control in the metallurgical industry. The device is installed on an upper cooler body in the sheet and strip steel cooling control system, and is composed of a driving device, a driving end frame, a driven end frame, a steel wire rope I, a steel wire rope II, a fixed pulley assembly, a water receiving disc assembly and a sliding rail, wherein two water receiving discs are controlled to be moved in the horizontal direction by adopting a steel wire rope traction mode, the temperature difference between the edge part and the middle part of the sheet steel in the water cooling process can be reduced, and the cooling uniformity and the overall performance of the sheet steel are improved. The device has the advantages of being high in high-temperature and high-humidity working environment adaptability, low in equipment failure rate and low in maintenance workload; the water outlet widths of the edge parts at the two ends of the upper cooler can be accurately adjusted on line, so that sheet steel with different specifications can be adapted; and the occupied space is small, the influence on other equipment is small, installation is convenient, and the popularization and application are easy.

Description

technical field [0001] The invention relates to the technical field of controlled rolling and controlled cooling in the metallurgical industry, in particular to an edge shielding device used in a controlled cooling system for strip steel. Background technique [0002] At present, controlled rolling and controlled cooling technology (TMCP) has been widely used in various medium and heavy plate and hot strip production lines. This technology can improve the microstructure inside the steel plate and refine the grains by reasonably controlling the cooling rate and final cooling temperature of the steel plate, thereby improving the overall performance of the steel and reducing the cost of the alloy. The implementation of controlled rolling and controlled cooling technology is mainly realized by spraying cooling water on the steel plate surface through accelerated cooling equipment. [0003] In actual production, when the steel plate enters the controlled cooling area, the coolin...
