Abstract

The invention discloses a wire and bar production line, and a high-precision product intelligent control system and control method suitable for the wire and bar production line. Real-time monitoring and closed-loop control over the outlet size of each unit are achieved through a rear diameter measuring instrument of each unit, an online roller and groove changing mechanism of a short stress path rolling mill, a roller gap adjusting mechanism, an automatic guide and guard replacing mechanism, an automatic overturning and automatic roller changing mechanism of a cantilever rolling mill, a roller gap adjusting mechanism, an automatic guide and guard replacing mechanism and a closed-loop control system for the outlet size of each rack. The labor intensity and the workload of an adjusting worker are reduced, the high-precision production of a wire and bar production line is improved, the intelligence of the production line is improved, the production stability and the production efficiency are improved, and the product quality stability and the generality are improved.

Description

technical field [0001] The invention relates to a wire and bar production line, a high-precision product intelligent control system and a control method suitable for the wire and bar production line. Background technique [0002] As an important product in the steel industry, wire and bar products have a wide range of products, including spring steel, bearing steel, cord steel, alloy structural steel, tool steel, rebar, etc., which are widely used in automobiles, machinery, bridges, metal Products, construction and other important national industries. With the rapid and sustainable development of my country's economy, my country's wire and bar output has continued to increase, reaching 487.14 million tons in 2019, accounting for 48.9% of my country's crude steel output. [0003] The configuration of the main wire rod rolling line unit mainly includes: heating furnace, rough rolling unit, intermediate rolling unit, pre-finishing rolling unit, finishing rolling unit, diameter...
