****（以下称招标机构）受****（以下称买方）委托，就其武钢有限冷轧厂精整分厂自动化系统提升改造项目纠偏仪表设备所需的下列货物进行公开招标，邀请合格投标人进行网上电子投标。

标段编号：****/01

标段名称：武钢有限冷轧厂精整分厂自动化系统提升改造项目纠偏仪表设备

1．招标货物名称、数量、技术规格和资金来源：

招标货物名称：纠偏仪表设备

数量：6套+1套附件

技术规格：

271、371机组纠偏仪表原型号备件停产，此次改造更新271和371机组的纠偏仪表设备（271机组含开卷机CPC*1套，圆盘剪CPC*1套，卷取机EPC*1套，带PROFINET通讯；371机组含开卷机CPC*1套，圆盘剪CPC*1套，卷取机EPC*1套，带PROFINET通讯）。

采用的设备及方案适配现场实际情况，满足现有安装空间、与L1系统和液压系统兼容。

（1）板带对中系统(CPC)的组成及功能描述

本项目中的板带对中系统主要由光电式测量传感器、数字控制器、直线行程传感器、伺服阀几部分构成。

该系统是一个连续的闭环调节系统；由传感器连续地测量行进板带的位置变化，将板带的位置偏差信号输入到数字控制器，电控系统的输出与伺服阀相连。伺服阀驱动液压油缸带动机架进行左右移动或摆动，使板带侧向移动，以调整跑****中心线上，实现板带自动对中功能。

直线行程传感器的值反映了机架的实际位置，必要时可作为位置反馈信号，参与闭环控制。

（2）板带对边系统(EPC)的组成及功能描述

本项目设计为无机械臂卷取机上的板带自动对边控制系统，系统设备主要由光电式测量传感器、数字控制器、直线行程传感器、伺服阀几部分构成。

该系统是一个连续的闭环调节系统；由传感器连续地测量行进板带边缘位置的变化，将板带边缘位置偏差信号输入到数字控制器，电控系统的输出与伺服阀相连。伺服阀驱动与卷取机相连的液压缸而使卷取机跟踪进带位置，达到精确卷取的目的。

卷取机是对板带边缘位置进行跟踪，而不是对板带位置的偏差进行纠正，对进带边缘位置的跟踪的结果，是使板带边缘对准一点卷取，达到板卷一边平齐的目的。对于任何卷取机的对边控制，传感器必须安装在转向辊附近。

本系统采用通过电气同步控制的方式实现卷取机对进带边缘位置的跟踪，其优点是可以取消传感器与卷取机相连接的机械臂，克服了卷取机上机械臂的振动带来对系统精度的影响。

（3）附件

含CPC/EPC内部连接电缆及配件（包含高频光源发射器连接电缆、直线行程传感器连接电缆以及控制器到前放盒的连接电缆）；设备机上液压配管；调试工具 （含数据连接线）等。

CPC/EPC of Automation System Upgrade Project of the Finishing Branch of Cold Rolling Mill of WISCO

Issue Date：2024-06-20

Tendering No：****

Tendering No. (China International Bidding Website):0721-****017G0495

Shanghai Baohua International Tendering Co., Ltd.(Hereinafter referred to as Tendering Agency) is commissioned by Wuhan Iron and Steel Co., Ltd(Hereinafter referred to as tenderer) on Open Tendering for the following goods required in CPC/EPC of Automation System Upgrade Project of the Finishing Branch of Cold Rolling Mill of WISCO invites eligible bidders to online e-bidding.

Bid section No：****/01

Bid section Name：CPC/EPC of Automation System Upgrade Project of the Finishing Branch of Cold Rolling Mill of WISCO

1． The name, quantity, technical specifications and fund sources of goods for tendering：

The name：CPC/EPC devices

Quantity：6 sets and 1 sets of related accessories

Technical specifications：

The spare parts of the original models of correction instruments for units 271 and 371 have been stopped production, and the correction instruments for units 271 and 371 are renewed this time (Unit 271 includes 1 set of CPC* of payoff reel, 1 set of CPC* of side trimmer, 1 set of EPC* of tension reel, with PROFINET communication; Unit 371 consists 1 set of CPC* of payoff reel, 1 set of CPC* of side trimmer, 1 set of EPC* of tension reel, with PROFINET communication).

The equipment and scheme adopted are suitable for the actual situation on site, meet the existing installation space, and are compatible with L1 system and hydraulic system.

(1)The composition and function description of CPC

CPC is mainly composed of photoelectric measuring sensor, digital controller, linear travel sensor and servo valve.

The system is a continuous closed-loop regulation system. The sensor continuously measures the position change of the moving strip, inputting the position deviation signal of strip to the digital controller. The output of the electronic control system is connected with the servo valve. The hydraulic cylinder drives the stand moving or swing right or left, so that the strip move sideways to adjust the deviation strip to the preset center line and realize the center penetrating function of the strip.

The value of the linear travel sensor reflects the actual position of the stand and can be used as a position feedback signal when necessary to participate in closed-loop control.

(2)The composition and function description of EPC

The strip automatic edge penetrating control system is designed for tension reel without mechanical arm. The equipment is mainly composed of photoelectric measuring sensor, digital controller, linear travel sensor and servo valve.

The system is a continuous closed-loop regulation system. The sensor continuously measures the change of the edge position of the traveling strip, and inputs the edge position deviation signal to the digital controller. The output of the electronic control system is connected with the servo valve which drives a hydraulic cylinder connected to the tension reel so that the tension reel tracks the incoming strip position for accurate coiling.

The tension reel is to track the edge position of the strip, rather than correct the deviation of the position of the strip. The purpose of tracking the edge position of the incoming strip is to coil the strip aiming at one point at the edge of the strip to achieve the flatness on one side of the strip. For side-to-side control of any tension reel, the sensor must be installed near the deflector roll.

This system adopts electric synchronous control to track the position of the edge of the incoming strip by tension reel. The advantage of this system is the mechanical arm connected between the sensor and the tension reel can be canceled and the influence of the vibration of the mechanical arm on the tension reel on the system accuracy can be overcome.

（3）Accessories

including: Interconnecting cables and accessories of CPC/EPC (including connecting cables of high frequency light emitter, linear travel sensor, as well as cables from the controller to the front junction box; and hydraulic piping on the machine.
