Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].
rolling mills (8 stand roughing rolling mill, 4 stand intermediate rolling mill, and 4 stand finishing rolling mill) was built by MorganSumitomo Heavy Machinery Co. Ltd.. In the 1980s, the aimed quality of products was shifted toward highvalueadded special steel quality, and, to achieve this, in 1986, a threeroll finishing rolling

As regards "abnormal" rolling conditions which are more or less very "normal" for rolling mills roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billets.

Other chapters consider the range of application of various types of rolls and show the basic dimensions of a roll. This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills.
May 02, 2017· Tandem rolling is also known as continuous rolling in which two or more set of four high rolling mill arranged in a series in which each set is called stand. These stands are arranged so they can roll the work piece in decreasing cross section. It is used for rolling thick work piece in single pass.
