The main character of this control is to set the sheet gauge calculated by bounce formula as practice gauge which is compared with the setting gauge or lock gauge. The difference is the gauge difference value and is regulated by screw-down system. In such a way, the character of this system is increased and avoids the influence of such factors as roll wearing, roll heat expansion and so on. Therefore, it can greatly increase the accuracy of sheet gauge. This paper analyses detailed introduction of the design way for tension automation control ATC, gauge automation control, L2 class software in the modification of AGC, explains the principles of control functions and how the AGC meets with the requirement of cold mill production.

并且，认为在自动厚度控制AGC应用中，依靠现代控制理论、电子技术与计算机技术新成就，采用AGC前馈控制，AGC反馈控制，AGC流量控制，ATC张力控制系统，其控制的主要策略是使原料的厚度变化经过1号轧机轧后趋于常量，以便确保后续轧机控制板型厚度精度，最终达到厚度精确控制的目标，提高冷轧带钢产品质量。

In order to further improve product quality, the company improved the cold-rolled sheet, press parts, drawing pieces, mold finishing, and other production equipment, now has 16-300 T on forging presses more than 100 Taiwan, cold-rolled sheet steel four sets of equipment, liquefied petroleum gas Annealing furnace four sets.

为了进一步提高产品品质，公司完善了冷轧薄板、冲压件、拉伸件、模具精加工等生产设备，现拥有16—300T上锻冲床100多台、冷轧薄板带钢设备4套、液化气退火炉4套。

When cold rolled strip is treated in a continuous annealing furnace which is full of protective gas,the gas tightness of the furnace body,connected facilities and wind channels is an important indicator,which directly concerns product's surface quality,and shows technical level of designers,manufacturers and erectors.

冷轧薄带钢在充满保护气氛的连续退火炉中进行连续退火处理时，炉体及相连接设备和风道的密闭性水平，直接关系到产品的表面质量，同时也是体现设计、制造和安装技术水平的重要指标。

The board form that keeps good in hot-rolling strip steel is all in all problem in producing a course.

梗概： 热轧带钢中保持良好的板形是生产过程中极其重要的新问题。

In order to improve the quality of "Xintongda" brand hot-galvanize series products and guarantee to carry out the latest national standard of GB3640-88 and GB/T2518-88, in Beijing and Guangzhou, we have invested large quantity of funds to introduce American Sendzimir hot-galvanize production line to manufacture "Xintongda" brand hot-galvanize series, including hot-galvanize braiding pipe, square pipe, rectangle pipe, circular pipe, wire pipe, electric cable bridge truss, C-steel and strip steel, etc. The products have enjoyed a good reputation for their best quality, various varieties and considerate after-service.

为提高&新通达&牌热镀锌系列的品质，保证产品严格执行GB3640-88和GB/T2518-88最新国家标准，在北京，广州等科研单位的协助下，我们又投入了大量资金，引进了美国森吉米尔热镀锌生产线，从而使热镀锌穿线管，方型管，矩形管，圆形管，线槽，电缆桥架，C型钢及带钢等&新通达&牌热镀锌系列的质量更保证，品质更超群，品种更繁多。

Through calculation of loopers ' quantity and analysis of rise and fall loopers control,control programme of PLC is adjusted.

通过对活套套量的计算及起落套控制的分析，调整了PLC的控制程序，实现了带钢轧制生产过程的稳定。

The article describes the type of loopers used in cold tandem mills and details the construction and application of horizontal and tower type looper s.

介绍冷轧带钢连续机组中活套种类，详细说明卧式活套和塔式活套的结构特点及应用范围。

A fragment about a size 300x400X10mm spalled from a φ400×1200mm 9Cr_2Mo cold working roll in an accident during rolling strips was investigated.

本文研究了一块300×400×10mm的剥落块，这个剥落块是在轧制带钢时因事故从Φ400×1200mm的9Cr2Mo冷轧工作辊上剥落下来的。
