Theoretical Minimum Energies To Produce Steel for Selected Conditions March 2000 R.J. Fruehan O. Fortini H.W. Paxton R. Brindle Prepared under contract to Energetics, Inc. Columbia, MD For the U.S. Department of Energy Office of Industrial Technologies Four-high rolling mill: Using small rolls reduces power consumption but increases the roll deflection. In this configuration, two small rolls, called working rolls, are used to reduce the power and another two, called backing rolls, are used to provide support to the

4 High Rolling Mill

Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used. This reduction in

Flat Rolling • Initial thickness ho • Final thickness hf • Roll gap L• Surface speed of rolls Vr • Entry velocity of strip Vo • Final velocity of the strip Vf • Neutral point, no-slip point –point along contact length where velocity of the strip equals velocity of the roll

smaller scale steel making operations typically used for the manufacturing of reinforcing steel. Typically an EAF melt shop is linked with a rolling mill, specialising in producing 'long' products such as reinforcing bars. Such a plant configuration is generally referred

stainless steel and alumi-num available from stock. With one of the largest non-mill inventories in the U.S.A., stocked in six service centers, we have what your project requires. As an added service, all of our facilities maintain pro-cessing capabilities in-house.


Selecting Optimal Ingot Sizes for Bethlehem Steel

BETHLEHEM STEEL reheated in furnaces before they can be rolled into their finished shapes. The 48 mill rolls an ingot of a given cross-section and weight into a long length (200 feet) of finished product, for example, an I-beam. A very specific ingot size and ingot

The following pages rep-resent sizes, weights, and dimensions of carbon steel, stainless steel and alumi-num available from stock. With one of the largest non-mill inventories in the U.S.A., stocked in six service centers, we have what your project requires. As an

In the present work, a low carbon steel sheet was taken and passed through the rolling mill six times. Each time the steel sheet was passed through the mill, it was stressed and there was somel amount of stretch in the housing of the mill. This

Work-hardening factors into the equation as well, especially when rolling material like stainless steel. Consider some classic stainless materials, ASTM 304 and 316, which have certificates that often indicate a yield strength close to 220 MPa (about 32,000 PSI).

POWER IN ROLLING Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip tension.The total rolling load is distributed over the arc of contact. However, the total rolling load can be assumed to be concentrated at point along the arc

Enter the width of a mill shell liner. Note this is not the width of a lifter! You may use the Mill Liner Effective Width calculation to determine this value. The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Mill Actual
