2021-2-16 tage over traditional plate mills. The single stand of a 4-high reversing Steckel mill carries out both roughing and finishing passes. With the increase of mar-ket demand on high-strength low-alloy (HSLA) steels, the mill needs to extend its roughing pass schedule to roll the steels due to the limit of torque. However, an extensive pass schedule does

2014-3-17 Rolling mills can use two, three or four rolls. In two-high reversing rolling mills, the rolled metal may pass back and forth through the rolls several times. The disadvantage of reversing mills is that the rolls must be stopped, reversed and then brought back up to rolling speed between each pass.

Reversing Cold Mills (RCM), consisting of a rolling stand, are the ideal plant type for an annual production in the range of 100,000 to 500,000 tons. They can roll a wide range of steel grades. Reversing cold mills are also a good solution for demanding silicon or stainless steels. We offer you the right type of stand for every product mix.

In the case of conventional 3Hi Reversing Mills, the material (blooms and billets) is laterally moved utilizing a manipulator, sent into the next pass caliber and rolled. On the other hand, in the case of a shifting reverse mill, the material is kept at the same place while the rolling mill is shifted to the next pass caliber position for rolling.

2017-10-28 Rolling Process Brief. The rolling process varies depending on customer's requirement for strip thickness. For a thicker strip (typically, 0.7-1.2 mm), for example, it can be finished in one round of rolling process with 5 to 7 passes. For a thinner strip, however, 2 to 3 rounds of rolling
