China ss sheet rolling machine

Plate rolling mill is one of the core equipment in the steel industry,and its technical level directly affects the thickness accuracy,surface quality,and production efficiency of steel.The China ss sheet rolling machine  has achieved effective rolling of high-strength,corrosion-resistant,and special performance steel by integrating high-precision control,intelligent adjustment,and energy-saving design.
1、Mechanical Structure Composition of SS Plate Rolling Mill
1.Main frame and rolling mill system
High rigidity frame:The China ss sheet rolling machine  adopts a prestressed closed frame structure,which locks the upper and lower crossbeams with hydraulic bolts to ensure that the deformation of the frame during the rolling process is less than 0.1mm,providing a foundation for high-precision rolling.
Four roll/six roll configuration:
Four roll rolling mill:The working roll diameter of the China ss sheet rolling machine  is small,and the supporting roll diameter is large.By using a large roll diameter to support and reduce the deflection of the working roll,it is suitable for rolling medium and thick plates.
Six roll rolling mill:equipped with an intermediate roll and a bending device,which can independently adjust the bending degree of the working roll,eliminate edge drop defects,and is suitable for the production of thin specification high surface quality sheets.
Roll material:The working rolls of the China ss sheet rolling machine  are made of high-speed steel or high chromium cast iron,with a surface hardness of HRC 60-65.The supporting rolls are made of alloy forged steel(such as Cr5),which balances strength and wear resistance.
2.Transmission and hydraulic system

Main motor drive:AC variable frequency speed regulating motor is used,with a power range from 5000kW to 20000kW.The power is transmitted to the support roller or working roller through a universal joint.

Hydraulic compression system:
2、The core process flow of SS plate rolling mill
1.Preparation of raw materials and furnace loading
Billet specifications:The China ss sheet rolling machine  selects continuous casting billets or mold casting billets based on the thickness of the finished product,with a length usually ranging from 6-12m.
Heating system:Three stage heating is adopted,and the total heating time is calculated based on the thickness of the billet to ensure temperature uniformity of±5℃.
2.Rough rolling and precision rolling stages
roughing:
Objective:The China ss sheet rolling machine  compresses the thickness of the billet from the initial value to the intermediate thickness,breaks the as cast structure,and forms uniform recrystallized grains.
Track allocation:Usually 5-7 rolling passes are used,with a reduction rate controlled at 15%-25%per pass to avoid edge cracking.
The China ss sheet rolling machine  has achieved high-precision and intelligent rolling of special steel by integrating high rigidity mechanical structures,multi-stage rolling processes,and intelligent control systems.Its core advantages lie in dynamic thickness compensation,full process shape control,and temperature uniformity management.In the future,with the integration of artificial intelligence and digital twin technology,SS rolling mills will evolve towards"unmanned,adaptive,and low-carbon"direction,providing better sheet metal solutions for the manufacturing industry.
