Metal Rolling

At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods.

Blooms are often rolled directly into I beams, H beams, channel …

COLD ROLLING MILL STRIP TEMPERATURE MEASUREMENTS

02 Cold rolling metal strip application note A cold rolling mill reduces the thickness of metal strip by applying a high pinch load between work rolls and a pulling load on the strip which causes the cross-section of the strip to change, making the strip thinner – which is controlled by the gap between the rolls – and longer by controlling elongation. Strip width is also changed …

WO2020121042A1

A method for mitigating the effects of coil collapse on hot strip mill coils. A hot strip coil (1) is removed from the mandrel/downcoiler and placed onto a mandrel (4) of a turnstile (2). The coil is held on the mandrel of the turnstile until it is cooled enough that the sagging rate of the coil is negligible. The coil is then removed from the turnstile and transported to another destination

Cluster Mills

Tags Rolling Mills; Cluster Mills. In all cases, one of the main advantages of a cluster mill is the large back up rolls. The back up rolls act as a heat sink because there is a considerable amount of heat energy going into the strip and the work roll. Much of the heat in the work roll is transferred to the back up roll. Having a large diameter

What Is A Rolling Mill?

Roll stands, holding pairs of rolls, are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock, and so on), bar stock, and rails. Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products.
