Optimization of cold rolling process parameters in order ...

In a roller mill, the grinding is done with oppositely rotating steel rollers. High quality roller balls are processed with grinding and casted with spinning technique. The surface hardness of the roller balls are 500-550 Brinell, and 20mm hardening depth ensures recurrently rethreading, and for this reason, a long life span.There are 2 couples ...

Chapter 3 Torsion

Before you can design the rolls, you must determine the proper number of passes and the rolling mill. After calculating the estimated strip width, you can develop the flower by using the arc and straight lengths. On a typical C channel, the return leg (bend No. 2) is the first forming to be done (see Figure 2). Some designers prefer to form ...

In the above formula: f – Coefficient of rolling friction, take f = 0.008m. μ – Coefficient of sliding friction, take μ = 0.05-0.1d 1,. d 2 – Upper roller & lower roller diameter (m). D 1, D 2 – Upper roller & lower roller neck diameter (m). The size is not yet accurate in the design phase, the value can take D i = 0.5d i (i=1, 2). The lower roller drive torque T equals the sum of ...

Steel

Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to ...

The basics of roll form tooling design

A new method is proposed to solve edge cracking and corrosion in rolling process of the magnesium alloy plate. Usually in the process, the edge cracking is caused by the great temperature difference between the edge and the center of the alloy plate and the corrosion is by water in air. The method uses hot air wrapped around the plate to perfectly prevent edge cracking and corrosion.
