In the modern steel industry, the continuous rolling mill, as the core equipment for metal plastic processing, has completely changed the traditional single-stand rolling operation mode with its efficient and continuous production characteristics.
It adopts a four-column prestressed frame structure design. The material of the archway is selected from ZG270-500 cast steel for integral casting. The dimensional tolerance of the window is controlled at H8 grade accuracy. It is equipped with a hydraulic prestressed device and an online deflection compensation system.
Typical configurations include various modes such as 4-roller, 6-roller, and 20-roller
The material of the work roller is selected from high-chromium cast iron. The support roller adopts compound forging technology. The assembly of the rolls adopts double-row tapered roller bearings.
It adopts AC-DC-AC variable frequency synchronous motor, gearbox, universal joint shaft, and is equipped with a hydraulic quick roll changing device, hydraulic roll bending system, AGC hydraulic cylinder, and roll balancing hydraulic cylinder.
The process control system includes: detection subsystem , laser velodrome, X-ray thickness gauge, infrared temperature array, surface defect detection CCD, control unit .
Auxiliary process systems: Temperature management system , laminar flow cooling unit, ultrafast cooling system, roller conveyor insulation cover, surface treatment unit , high-pressure descaling system, electrostatic oiling unit, in-line grinding roller unit.
The modern continuous rolling mill system has achieved a leapfrog improvement in the three core indicators of rolling accuracy, production rhythm and energy consumption efficiency through the deep integration of precise mechanical design, intelligent control technology and advanced processes.
