Cooling bed blanking and finishing process production line and its control method

Abstract

The invention belongs to the field of hot rolling production, and discloses a production line of a cooling bed blanking and finishing process and a control method thereof. The cooling bed blanking and finishing process production line includes: a cooling bed; a feeding device connected to the output end of the cooling bed, the feeding device includes a plurality of discharge ends arranged at intervals along its feeding direction; A plurality of finishing production lines connected respectively, the length direction of the finishing production line is perpendicular to the feeding direction of the unloading device. Wherein, the unloading device is set to be able to alternately transport the rolled piece to the corresponding finishing production line through different discharge ends. The cooling bed blanking and finishing process production line of the invention can improve the production efficiency of small-sized rolled pieces.

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
