基于全套孔型模型开发一个孔型设计程序

With Excel worksheet and the spread [宽展] model [模型], the a roll [轧辊] pass [道次] design [孔型设计] program was created during the GST 19” Mill roll [轧辊] pass [道次] design [孔型设计], and was then used for several other roll [轧辊] pass [道次] design [孔型设计] projects.

开发一个基于Windows的孔型设计程序用以设计多达28道次的孔型系列

An initial [初始] version [版本] of the roll [轧辊] pass [道次] software [软件] was developed [开发] to roll [轧辊] steel from square [方] billet [方坯] to round [圆] in up to 26 - 28 pass [道次] (depending on number of stands in the mill). The designs included roughing [粗轧], intermediate and finishing [精轧] pass [道次]. developed [开发] with VB/VC++.

开发一个应用程序,通过读取Excel文件作为数据库,将其插入到公司内部网站的网页,从而易于管理及阅读Excel文件

According to the Requirement [要求]: (1) multiple [多] users should be able to access the most current file [文件], which may be updated frequently by those with privileges [特权] to update them; (2) Common users should not be allowed to change the file [文件]. The intranet [内部网] web [内部网路] provided the right solution. The Excel file [文件] was displayed on the intranet [内部网] web [内部网路]ite, with its look-and-feel exactly like Excel.

一个应用程序的开发,用以管理工程文件,和将图纸(AutoCAD格式)和现实于内部网的网页上。

Requirement [要求]: (1) Some AutoCAD drawing [绘制] should be accessible for view by multiple [多] users; (2) Other file [文件] in the same storage [存储] location should not be viewed by all the people; (3) Viewable file [文件] should provide the most current version [版本]. The intranet [内部网] web [内部网路] was the perfect solution, so an application was developed [开发] to load the selected drawing [绘制] onto the intranet [内部网] web [内部网路].

开发一个软件工具,使其直接将PLC的数据填充到网页画面

Some people want to see the live data [数据] of the PLCs [可编程控制器]. PLC [可编程控制器] may have more data [数据] than Level 1 or Level 2 [二级系统], and the data [数据] from PLC [可编程控制器] were the original. An application was written to access PLCs [可编程控制器] addresses directly for data [数据]. The application was also particularly useful in the debugging period for the Level 1 and Level 2 [二级系统] applications [应用程序].

一个基于网路的孔型设计程序套件开发-称作“自动成型”,以便网路用户进行自动的孔型设计

This set of applications [应用程序] allowed the user to do roll [轧辊] pass [道次] design [孔型设计] without existing experience. The user only needed to fill in the required mill operational data [数据]. Two sets of roll [轧辊] pass [道次] model [模型] were combined in the software [软件]: the first set, with few factors [因素] considered, to do the first assessment [预估], and the second, with many factors [因素], to perform the high quality design. The combination of the two steps with those two sets of model [模型] provides both speed [速度] and quality of the roll [轧辊] pass [道次] design [孔型设计]. See www.metalpass [金通].com/roll [轧辊]design.

一个基于网路的孔型设计程序套件开发-称作“自由成型”,以便有经验的孔型设计者可通过网路进行高质量的孔型设计

This set of roll [轧辊] pass [道次] applications [应用程序] were provided with more flexibility (freedom) for the roll [轧辊] pass [道次] design [孔型设计]er, and the model [模型] covered more influence factor [影响系数] such as the tension [张力] influence on the spread [宽展] and forward slip [前滑]. This set of programs could design multiple [多] pass [道次] (e.g. up to 28). The user could also select various design procedure [程续] for spread [宽展] and for forward slip [前滑] calculations. data [数据] for all pass [道次] could be saved and reloaded. See www.metalpass [金通].com/freeform.

一个有限差分程序开发,以确定轧制生产中温度分布和控制,包括轧制,空冷和水冷各个过程

The web-based [基于网路的] finite difference program was designed to predict temperature [温度] profile [温度形态] (surface, center, average, middle, etc.) pass [道次] by pass [逐道次的], from the furnace [炉子] dropout [出炉] until the completion of the water-cooling [冷却] and airbed cooling [冷却]. The user could save the input data [数据] for all the stages on his local [局部] computer, and reload the saved data [数据] in the future by reading the saved file [文件]. Various optimization [优化] steps were done so that the program could run sufficiently fast. Running web-based [基于网路的] numerical solution truly demonstrated [展示] the technical skills of Metal Pass [金通], both in mill process and IT aspects. See www.metalpass [金通].com.

存储脚本程序开发以在SQL服务器数据库中为网站metalpass.com准备数据

Data [数据] from database [数据库] was loaded to the web by running stored procedure [存储脚本程序], so the internet user had only the right to run the pre-written stored procedure [存储脚本程序], and could not query through the database [数据库]. This was critical [严峻] for data [数据] security [安全] in the internet applications [应用程序].

开发了一个图形化的程序,以显示数据库中数据的趋势(通常是数百万条记录)

This tool was developed [开发] to quickly display major influence factor [影响系数] for the force [轧制力] error [轧制力误差]; it was also aimed at handling [处理] large amount of data [数据] (about a million [百万] records), for which graphical [图形] drawing [图形绘制] with Excel was not efficient [有效].

SQL脚本程序开发,以抽取 二级系统/ 三级系统 数据库数据送往局部 SQL 伺服器

For automatic query of data [数据] from OSM [俄勒冈轧钢厂]^s Informix database [数据库] for needed data [数据]. data [数据] was queried into local [局部] SQL server [伺服器] for further processing [处理] and evaluation [品价].

SQL脚本开发,以计算和转换数据(用于轧制力误差计算,数据四舍五入,数据选择等)

These script [脚本] [脚本] were to calculate error [误差], to transform data [数据] or to select certain data [数据] inside the SQL server [伺服器]. For example, to study the influence of a factor (e.g. temperature [温度]), the other factors [因素] (e.g. strain [应变]) should remain unchanged. This is, however, impossible in the real, life data [数据]. What was done was to round [圆] the other Parameter [参数] (e.g., to round [圆] 0.29 into 0.30 and 0.305 into 0.30). The round [圆] work was done inside SQL server [伺服器] with SQL script [脚本] [脚本].

镰刀弯测量, 预报和消除系统开发(为俄勒冈轧钢厂镰刀弯研究组所提出的工作计划,约28页)

Use cameras to measure [测量] the camber [镰刀弯] and then use the model [模型] to calculate the Draft [压下量] for the two sides in the roll [轧辊] gap [辊缝] in order to adjust the roll [轧辊] gap [辊缝] in the two sides (with AGC) and to reduce or eliminate [根除] the camber [镰刀弯].

关于几个改进的机会及解决方案的建议

(1) OSM [俄勒冈轧钢厂] Level 2 [二级系统] force [轧制力] model [轧制力模型] Problem Solution (Work plan, 8 pages, for the meeting on Sept. 2007); (2) Development [开发] of OSM [俄勒冈轧钢厂] Material [材料] processing [处理] system [系统] (slab [板坯] processing [处理] + Finish processing [处理]. 16 pages); (3) OSM [俄勒冈轧钢厂] Reheating [再加热] Process Improvement [改进] (8 pages); (4) Development [开发] of a temperature [温度] simulation [模拟] system [系统] for OSM [俄勒冈轧钢厂] Heat Treating [热处理] Furnace [热处理炉] (13 pages); and (5) prediction [预报] of rolled [轧后] Steel Properties [钢轧后性能] (4 pages).

通过更充分使用轧制力和轧制力矩,减少轧制规程道次

An offline [离线] model [模型] was used to search for the optimum [优化] utilization [使用] of force [轧制力] and torque [力矩] in rolling [轧制] pass [道次]. Parameter [参数] were adjusted in Tippins, Ansaldo, Prosoft and GE model [模型] to duplicate [复制] the optimum [优化] from the offline [离线] model [模型]. A subroutine [子程序] in Fortran or C++ was installed in the existing Level 2 [二级系统] to adjust the drafting [压下], if the existing model [模型] did not have good tuning Parameter [参数]. Tables for flow stress [流变应力] were adjusted, if needed, after looking at the error [误差] in the force [轧制力] and torque [力矩] prediction [预报].
