Embodiment Construction

[0030] In order to enable those skilled in the technical field to which the application belongs to understand the application more clearly, the technical solutions of the application will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0031] The invention provides a method for setting the level value of a roughing mill, which is applied to figure 1 The hot continuous rolling mill shown in the figure includes a plurality of heating furnaces 1 and rough rolling mills 2 arranged in sequence. In an embodiment, the multiple heating furnaces 1 may include three regenerative heating furnaces and one conventional heating furnace, and the rough rolling mill 2 includes a first rolling mill 21 and a second rolling mill 22 . The rough rolling mill 2 also includes a width-sizing machine 23 (i.e.: SSP) arranged at the outlets of a plurality of heating furnaces 1, and a finishing mill 4 and a coiler 5 are arranged in turn at the out...

Abstract

The invention discloses a roughing mill level value giving method, which comprises the following steps of: judging whether a plate blank from a heating furnace meets the last-pass steel throwing condition of a first rolling mill or not, and if so, judging whether steel exists in a second rolling mill or not; if no steel exists in the second rolling mill, controlling the horizontal value of the second rolling mill to be set to a target horizontal value; and the target horizontal value is a horizontal value, corresponding to the previous plate blank, of the second rolling mill in the same heat as the next plate blank. The method can solve the problems of intermediate plate blank waste pushing accidents and steel piling accidents caused by plate blank head deviation in a hot-rolled strip steel rolling process in the metallurgical industry.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a method, device and system for setting a rough rolling mill level value. Background technique [0002] In the hot-rolled strip steel rolling process in the metallurgical industry, with the gradual acceleration of the rolling rhythm and the gradual reduction of the rolling thickness, the requirements for each process are getting higher and higher. The state of the rough rolling intermediate billet determines the rolling stability. crucial aspect of sex. The state of the incoming slab is affected by many aspects such as furnace times, steel types, specifications, etc. When the incoming slab changes, the roughing mill level value of two adjacent slabs can change by 1mm, which increases the slab head. The risk of internal deviation and stacking of steel limits the release of production capacity of the production line. Therefore, it is necessary to provide a method to solve the ...
