Wrapper Roll Control System of Hot Strip Mill

Wrapper roll is one of the most important components in rolling coiler. And it has great relation to the quality of the final products. Based on the programming and optimization experience, a hot strip coiler with new coiling process, which operates with position control and pressure control is introduced.

Designing of Hot Strip Rolling Mill Control System

The second stage, when the strip tail through the last finishing mill and signal from 1 to 0, the speed of mandrel equals the speed of strip which switch from tension control to speed control, the speed of the hot run out table, pinch roll and wrapper roll is less than the speed of strip, the value of lag rate is given in man-machine interface

HOT STRIP MILL DOWN COILERS Casey USA

The strip enters the downcoiler from a pinch roll and is immediately formed around the mandrel using wrapper rolls. Unlike a traditional coiler, a hot strip mill downcoiler utilizes a series of rolls and sensors to maintain tight and well aligned coil wraps. The

Highest performing Hot Strip Mills Primetals

HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS 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.

Rolling conditions in hot strip mills and their influence

2006-3-27  The mechanical rolling conditions in hot strip mills are precisely defined by various variables, which are taken directly froth the rolling schedule (separation force, torque. speed. strip thickness) or calculated from figures of the rolling schedule and dimensions of the mill (strip reduction, roll

2015-12-3  CVC technique has slower dynamics but a wider range than work roll bending. Since CVC and work roll bending complement each other, both the techniques are normally used in the modern hot strip mills. During recent years, there is an increasing demand on the profile, thickness, flatness and the surface of the hot strip.

ROLL SPEED SET-UP IN HOT STRIP FINISHING

2007-1-1  Hot strip finishing mill is initially set up with rolling conditions such as roll speed, roll gap, and cooling pattern obtained by a set-up model. To improve the accuracy of initial roll speed setting for a 7–stand finishing mill, an equation for predicting forward slip and a compensation method for initial roll speed setting were proposed
