Cooling bed discharging and finishing process production line and control method thereof

Abstract

The invention belongs to the field of hot rolling production, and discloses a cooling bed discharging and finishing process production line and a control method thereof. The cooling bed discharging and finishing process production line comprises a cooling bed, a discharging device connected with the output end of the cooling bed and a plurality of finishing production lines connected with discharging ends respectively, wherein the discharging device comprises the multiple discharging ends arranged at intervals in the conveying direction of the discharging device, and the length direction of the finishing production lines is perpendicular to the conveying direction of the discharging device. The discharging device is arranged to convey rolled pieces to the corresponding finishing productionlines alternately through the different discharging ends. The cooling bed discharging and finishing process production line can improve the production efficiency of the rolled pieces of the small specifications.

Description

technical field [0001] The invention belongs to the field of hot rolling production, and in particular relates to a production line of a cooling bed blanking and finishing process and a control method thereof. Background technique [0002] With the increasing demand for rolled pieces in our country, the rolled piece production line is gradually developing towards specialization, scale and economy. For example, the production scale of the bar production line has grown from the initial annual output of 600,000 tons to more than 1 million tons. The equipment capacity of the production line has undergone tremendous changes, which has led to a major change in the production capacity of the bar production line. [0003] In the prior art, as the rolling of the rolled piece is completed, it needs to be transported to the cooling bed by the feeding device for cooling, and then passes through: the feeding device, the output roller table, the sizing cold shear equipment and the collect...

AI Technical Summary

Problems solved by technology

For the production line of small-sized bars, the shearing capacity of the fixed-length cold shearing equipment is mainly determined by the number of shearing counts, that is, the width of the cutting edge of the fixed-length cold-shearing equipment. If the width of the cutting edge is too large, it will easily cause the support of small-sized bars. If the number is too large, the bar is prone to winding problems during the shearing process, and it is difficult to ensure the accuracy of the shearing; while the width of the shearing blade is too small and the production efficiency is directly reduced.

Therefore, in the prior art, the cutting edge width of the fixed-length cold shearing equipment and the corresponding blanking device, output roller table, and roller table width of the collecting equipment limit the productivity of small-sized rolled pieces, that is, the entire strip production line bottleneck
