Abstract

The invention belongs to the technical field of rough rolling and discloses a method for improving the rough rolling rhythm of strip steel. The method includes the steps that a rolling mill double-descaling water cooling step is adopted, and the temperature of plate blanks in the rolling process is lowered, wherein by adopting the rolling mill double-descaling water cooling step, descaling water is sprayed to the plate blanks at an inlet and an outlet of a rolling mill correspondingly. The method for improving the rolling rhythm by shortening the steel placement time is efficient and stable.

Description

technical field [0001] The invention relates to the technical field of rough rolling, in particular to a method for improving the rough rolling rhythm of strip steel. Background technique [0002] The low-temperature rolling technology of ultra-low carbon steel is mainly to develop the ferrite rolling process. Generally, the furnace temperature must be below 1200°C, and the R2DT must be below 900°C. The two roughing mills must adopt a 3+5 mode to meet the temperature and rhythm requirements as much as possible. . [0003] However, before the last pass of R2, the temperature of the rolling steel is lowered to meet the needs of finishing rolling; however, the steel swinging time is as short as 30S and as long as 100S, which seriously affects the rhythm of rough rolling and leads to the suppression of production line capacity. Contents of the invention [0004] The invention provides a method for improving the rhythm of rough rolling of strip steel, which solves the technica...
