◎辊筒采用4台直流电机分别驱动，调速范围广，辊筒速比可任意调配。具有预负荷装置（辊筒拉回装置）、轴承润滑断油报警装置；具有辊筒间距显示和辊筒速度显示。

◎辊筒材料采用钒钛合金冷硬铸铁，表面坚硬耐磨。辊筒结构采用钻孔或中空方式进行加热或冷却，使辊面温度均匀。

◎辊筒排列呈S形状，１^#和４^#辊筒工作表面带有中高度，可消除工作时辊筒产生的弯曲影响，因而可得到沿宽度方向厚度均匀的制品。

◎传动系统选用硬齿面减速器，结构紧凑，噪音低，效率高。

◎机器设有安全装置，遇到紧急事故时，能立即停车并打开辊距，以保护人身和设备的安全。

◇The 4 rolls are separately driven by 4 DC motors, which allow a wide rang of speed adjustment. The rotating speed ratio of the 4 rolls can be freely adjusted. The rolls are equipped with per-loading device and lubrication failure alarm device, as well as nip display and speed display.

◇The rolls are made of chilled cast iron of vanadium and titanium alloy. The roll face is hard and anti-wear. For heating up or cooling down, the rolls are either circumferentially drilled or centrally bored so as to make temperature well proportioned on the roll surface.

◇The rolls are arranged in S form. Roll 1^# and roll 4^# have roll cambers that can eliminate bending impact on rolls in the working process. Thus it is possible to make products with same thickness along axial direction.  

◇The transmission system adopts a hard-gear speed reducer, which has a compacted structure with higher transmission efficiency, lower noise and longer service life.

◇The machine is equipped with emergency device. When an emergent accident occurs, the calendar will be immediately stopped to open the roll space so as to protect the operator and equipment.

◇PLC program controller is used in the electric system.
