Figure 1 from Strip Thickness Control of Cold Rolling Mill

In rolling mill, the accuracy and quality of the strip exit thickness are very important factors. To realize high accuracy in the strip exit thickness, the Automatic Gauge Control AGC system is used. Because of roll eccentricity in backup rolls, the exit thickness deviates periodically.

Strip Thickness Control of Cold Rolling Mill with Roll

Nov 12, 2013 been developed for hot or cold mill processes. The Brit-ish Iron and SteelResearch Association B1SRA AGC method based on the gaug meter principle and the feede forward AGC method using the delivery time of the strip have been widely utilized in steel rolling mills 3. Strip products thickness precision is an important quality parameter.

Stability and Accuracy of AgcSystems in Hot Strip Mills

Jan 01, 1983 INTRODUCTION Most hot strip mills are equipped with AGC-systems on the finishing stands. Installations vary from single stand to all stands AGC, hydraulical or electrical positioned. In most systems a feedback monitor control is available, in modern installations a

Flatness Control System for Hot Strip Mills ScienceDirect

Aug 01, 1981 Flatnes Control System for Hot Strip Mills Effect on Automatic Gauge Control Automatic gauge control AGC of final stand of finishing mill had not been used before flatness control was developed. The main reason is that when AGC of final stand is activated, the variation in rolling force injures flatness of the strip.

Highest performing Hot Strip Mills Primetals Technologies

The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a key element of steel production. Since close to half of all steel produced is hot-rolled to strip, mills require maximum throughput and availability ...

Research and Application on Spring Model of Hot Strip Mill

Spring model is important restrictive factors to improve the precision of AGC control system. To improve the accuracy of strip gauge control, Study on various influencing factors of spring model has important significance in rolling process. Therefore, using ABAQUS finite element software, this paper establishes the whole stand model of strip rolling.

Technology of the Full Continuous Hot Strip Rolling. As described above, in 1996 the endless hot strip mill was operated ahead of the world in the third hot rolling factory at Chiba steelworks of Kawasaki steel company. 105 In this facility a rough bar is joined in front of a finishing mill train, in which it is rolled consecutively without a ...

Application of Hot Rolling Lubrication on a Reversing

In the application of roll lubri--ing hot rolling mills, several con-cerns arise, i.e., bite and roll slippage and effectiveness. This paper studies the mechanism of roll lubrication of the reversing hot rolling mill theoretically and investigates the effect of the roll lubrication on mill

Hot Rolling Mill Hydraulic Gap Control HGC thickness

P. Kucsera et al. Hot Rolling Mill HGC Thickness Control Improvement 98 Another way to determine the thermal expansion of the work roll is the modelling of the heat transfer between the work rolls and the strip. This depends on the roll speed, strip thickness, the properties of the strip, roll gap, contact time and cooling parameters.
