Features总体描述

Modern designed steel cabinet built up with welded rectangular steel tubes. Swing away control panel mounted on a tubular steel arm. Heavy duty machined U-shaped frame for the roll assembly. The rolls are machined from high-grade tool steel, which has been treated to a hardness of over 60 Rockwell C, and hard chromed, precision ground as well as polished to a mirror surface. The rolls are mounted with dual heavy-duty needle bearings on each shaft and resting in machined bearing blocks. The grease lubricated bearing assemblies are built with special heat resistant seals on the roll sides to prevent leakage and to ensure a long bearing life at high temperature.

现代设计的钢构架结构，高负荷加工的U形支架；辊由高等级工具钢加工而成，经过特殊加工其硬度超过洛氏硬度60，同时采用高精度的镀铬工艺并镜面抛光。辊轮的每个轴上安装了重型双滚针轴承并安放在机加工的轴承座上；油润滑的轴承组件由侧面特殊设计的防热密封片保护，从而防止泄漏并确保轴承在高温下的长寿命。

Central Nip Gap Adjustment with Digital Electronic Nip Gap instrument on the Control Panel for readouts in increments of 0,1 mm.

中央夹紧调整通过控制面板上的数字显示控制装置实现，显示调节间隔0.1毫米。

3-Zone Electric Roll heating where the central and end part of the rolls are heated individually. Two separate PID controllers regulate the temperature of each roll. One for the center part and the other for the end parts. This system compensate for the heat conducted through the roll shafts and bearing assemblies and thus gives a more even temperature over the entire roll surface.

三区独立电加热 --- 中央部位和两侧独立加热，两个单独的微分控制器分别控制每一个辊轮，一个控制中央区域另一个控制两侧。此系统可以补偿辊轴长度区间以及轴承组件的热传导，因此可在整个辊轮表面获得更加均匀的温度一致的分布。

Single speed motor drive connected to a Helical Worm Gear and a totally enclosed Connecting Gear Box with heavy duty chain drive to the rolls and with fixed friction ratio according to customers request (normally 1: 1,2).

系统带有同螺旋涡齿轮以及全封闭齿轮箱的单速马达，它带有重型链传动系统并可根据客户的需要固定摩擦比（通常为1:1.2）。

Swing open left and right side top cabinets with swing away control cabinet.

主电柜之上左右两个分电柜可柔性开合，控制面板同样可柔性移动。

Non-Touching Split Type Bronze Side Platens.

非接触式分离青铜侧挡板。

Bronze Scraping Knife with holders at front and rear part of the rolls.

辊前方及后方带支撑式青铜刮刀。

Safety features according to European Safety Norms ( CE ) comprising of:

参照欧洲安全标准的结构设计，包括：

ü         Protection cage over the rolls with interlocked swing open front and rear parts, which

stop the rolls when opened.

辊上方有保护罩，在保护罩打开时辊自动停止。

ü         Stop bar over the rolls which, when activated, will instantly stop and alternatively

reverse the rolls.

制动杆在启动时，可立即停止辊转动或使其反向转动。

ü        Interlocked Swing Open left and right top panels which stops the rolls and cuts of the

electric supply when opened.

上端左右电柜带柔性自锁，打开时辊及电源自动停止。

ü        Interlocked rear cover to control panel, which cuts of the electric supply if the cover

       is removed.

       控制面板带安全自锁，在打开时电源被自动切断。

ü        Safety main electric switch handle on the door tothe electric cabinet, which cuts off

 the main supply when the door is opened.

 电柜门把手联动电源开关，在门被打开时总电源被自动切断。

ü         Self-locking Emergency Switch on top of control cabinet, which stops and

 alternatively reverse the rolls the rolls instantly and also cuts off all electric supply

  to the mill.

 上端控制柜带紧急自锁开关，在紧急情况下使辊反向转动或停止，并

  同时切断辊电源供应。
