USSM currently owns 8 rolling mills of three different configurations: 1 high-tech advanced 20-High mill, 2 Four High mills (H-mill), and 6 Sendzimir mills (Z-mill). H-mills are the simpler of the two, and use two large diameter work rolls which are driven and supported by a set of back up rolls situated atop and below, hence four high.simulation of a complex process such as a temper rolling line, including the payoff, rolling and coiling processes, is the first trial. 2.

Method for temper rolling of a thin gauge steel strip . Therefore when the rolling is conducted by a four high two stand tandem type rolling mill applying rolling oil between the work rolls and the steel strip in both of the two stands the elongation of the steel strip will change uncontinuously up to about 5 herein called jumping phenomenon with slight variation in The validity of this model for calculating temper-rolling force has been proved by the tests on a 4-high temper rolling mill in Baoshan Iron & Steel Ltd., in which elongations and distributions of thickness and rolling force were measured. Table 1 gives the parameters of material and rolling process and Table 2 gives the contrast betweenA new rolling force model for dry thick temper rolling strip mill

The calculation of rolling force Innoval Technology
Factors which influence the rolling force Yield strength. The main factor influencing the rolling force required to reduce the thickness of strip in a rolling mill is the yield strength of the material being rolled. The calculation of yield strength depends upon a wide range of factors. These are: composition; previous work done on the materialA study on temper rolling process has been carried out using rigid-plastic finite element method. Rigid-plastic formulation can be used to predict the roll force and roll torque and to study the deformation field of the rolled sheet. Hitchcock’s formula for roll deformation does not consider the effect of frictional traction on the roll deformation.A rigid-plastic finite element analysis of temper rolling process

Looper and tension control in hot rolling mills: A survey
Looper and tension control, shown in Fig. 2, is important in hot strip mills because they affect both the dimensional quality and the mass flow of a strip. The high strip tension between stands induces width shrinkage, thickness reduction and moreover can produce an edge wave on a strip. However, it does make the mass flow more stable and To reveal the generation mechanism of the quarter buckle in the process of hot-rolled temper rolling, the elastic–plastic finite element method is used to calculate the deformation of the roll and the strip during the temper rolling. The change of the cross section of the strip and the distribution of the longitudinal stress are analysed under Generation mechanism of quarter buckle in hot-rolled temper rolling
