control. When the tension control switch to the speed control, to cancel the additional speed Δn. In the working process of the coiler, from the strip head into the mandrel set up tension to the strip tail left the last finishing mill, the coiler entered the stage of tension control. Strip .
12 DFP Air Cylinder Regulator • Velocity affects air cylinder regulator combination • Pressure regulator can make or break dancer system • Must have sensitive relieving regulator (grab dancer arm pull up quickly) Air Reservoir Recommended: Add an air reservoir between the regulator and reservoir volume must be much larger than the cylinder volume
a conventional control system are provided. Key words: Loopers, Covariance control, Variance control, Hot strip mill, Hot rolling 1 Introduction A flnishing mill produces thin sheet from hot steel bars by successively reducing the gauge using 5 to 7 sets of rolls, each called a mill stand. The flnishing
TANDEM COLD MILL Tandem coldmill solutions from Primetals Technologies stand for high product yields combined with flexible production, low operational costs and simplified maintenance work. Depending on the product mix, the production capacity of continuous tandem mills from Primetals Technologies can exceed million tons per year.
More advanced control systems use tension meters (Zhao et al., 2008) to measure the current strip tension. Choi et al. (2007a) advocate the use of linear model predictive control (MPC) for loopers and strip Strip Mill stand Looper Fig. 1. Tandem rolling mill with ve mill stands. tension as this control approach facilitates a systematic
Tension control system for universal mill , Ltd. Jan 18, 1977· A tension control system for use in a continuous rolling mill system comprising a plurality of rolling mills each having horizontal and vertical rolls for simultaneously applying rolling loads on the same section of a billet to be rolled, electric motor means for driving said ...
Since tension and looper control is the key to successful operations in the hot strip finishing mill, several multivariable controllers have been applied. However, this leads to complicated controllers, which are hard to tune on site. This paper presents a new control method based on decentralization and coordination.
Pneumatic friction brakes used to control tension on an unwinding roll. Double E supplies a complete line of pneumatic brakes. Ideal for corrugators, paper sheeters, and many other converting machines. Double E pneumatic brakes run cool and quiet on unwind stands so brake pads last far longer than competitor''s brake pads.
Aimed at the complex demand of hot strip rolling mill in practicing, the configuration of the coiler and the technological process is analyzed. The arithmetic of coiling tension and the control process is introduced. The frame of the tension adjusting system is given. The coiler control system hardware is designed. The system is designed scientifically with steady control and meets demand of ...
Abstract: In this paper, a gauge and strip tension control system for a hot strip finishing mill based on the optimal regulator theory is presented. In hot strip finishing rolling, there exists a mutual interaction between gauge and strip tension control. Since the conventional control system, which consists of singleinput and singleoutput controllers, is limited in improving the control ...

This parameter, directly related to rolling fundamentals, simplifies the setup and operator control. During production the loop and tension control automatically adjust the R Factor, ensuring minimum material stress between the stands. No matter if you have one strand or two we have the solution for controlling your mill.

OUTLINE OF REVERSING COLD ROLLING MILL Outline of reversing cold rolling mill and rolling method As illustrated in Figure 1, a reversing cold rolling mill is structured mainly of a mill proper, a winding machine (payoff ree l), an entry winding machine (tension reel) and a deliverywinding machine (tension .
equipped with a bender, and a tension reel; however, a hitension hot mill line having a bridle roll and a tension leveler added to that also exists. The arrangement is shown in Fig. 4. Stable extension rate control and rolling of a thin hightensile strength steel plate under high tension have become possible, and a flatness comparable to a cold
