High-speed Module Mill is a kind of
high-speed wire rolling equipment with modular and independent transmission. By decomposing the traditional centralized transmission of multiple rolling mills into standardized units (modules) with multiple independent drives, it achieves high precision and high flexibility. Its core design subverted the mainstream collective transmission mode of the 20th century and became an innovative technology in the modern steel industry.
Core technology breakthrough
1. Modular design
Independent transmission unit: Each rolling mill is driven by a separate motor, which eliminates the power distribution error of the gearbox (the speed difference of the traditional rolling mill is up to ±3%).
V-type 45° top crossing layout: The roller is spatially cross-arranged to realize Torsion-free Rolling and solve the problem of wire surface scratching.
Quick roller change system: The specification change time is shortened from 8 hours of traditional rolling mills to 30 minutes, improving production efficiency by 50%.
2.Ultra-high-speed rolling capacity
Rolling speed: from the traditional rolling mill ≤60m/s to 115m/s (the actual measured value of the Tosyali project in Turkey).
Dynamic speed drop compensation: Instant adaptive speed adjustment of biting steel, speed fluctuation ≤±0.1%, ensuring the accuracy of head and tail dimensions (tolerance ±0.1mm).
3.Green manufacturing technology
Low-temperature direct rolling: continuous casting billet 750℃ direct rolling (traditional process requires 1200℃), ton steel energy-saving 3000m³ natural gas (Shanxi Jianbang Project).
Alloy reduction process: Three-stage controlled cooling (TMCP) reduces the manganese content of HRB400E rebar to 0.8% or less, and the cost of ton steel is reduced by 100 yuan.
