Zoom-Mill™ rolling improves off-gauge rolling ratios by 1% as compared to conventional rolling mills. In the case of 6-pass rolling, the length of the off-gauge portion of the coil periphery will usually be more than 10 meters. However, the use of the Zoom-Mill™ rolling method will enable a finish with the off-gauge at less than 2 meters.
The shape control characteristics of the rolling mill can be fully played by researching the influence of di erent factors on the bearing roll gap [11–14]. For bearing roll gaps, Z. D. Han et ...

A Tandem rolling mill is a Rolling mill with 2 or more close-coupled Stands, each of which is setup for rolling by using its Spring Curve and the Compressive Curve of the metal so that both the Rolling Force and the exit thickness of each Stand are determined.. The main advantages of a Tandem Mill are: only one single pass is required which saves time and increases …
2.1.2 Re-rolling mill furnace a) Batch type A box type furnace is used as a batch type re-rolling mill. This furnace is mainly used for heating up scrap, small ingots and billets weighing 2 to 20 kg for re-rolling. Materials are manually charged and discharged and the final products are rods, strips etc. The operating temperature is about 1200 ...
width, edge drop and shape at the exit of a hot rolling mill. The wealth of process control and quality assurance data from these measurements helps mill operators improve operating practices, thereby improving mill throughput and yield. Thermo Scientific RM 312 Multi-Function Gauge The Thermo Scientific RM312 demonstrates
In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold ...
The mill will feature Danieli OSRT shaped rolls for superior flatness-correction below 5IU. Strip thickness tolerance will be ± 0.6%, with head/tail off-gauge length lower than four meters. Within the galvanizing line the Danieli Kohler X-Jet wiping system will perform extremely accurate control of final zinc coating thickness, down to 30 g/m2 ...

Rolling Practice and Rolling Tolerances Universal mills are used for rolling W, S,C, MC, S, L and shapes. The thickness of the flange and the web may be HP changed with corresponding changes in the beam depth and flange width. The thickness of the web may be changed with a corresponding change in the flange width. All other dimensions
1. 2. HiWEDGE is a non-contact laser optical system for direct on-line measurement of the wedge and width of hot and cold slabs or plates. When located up-stream of the roughing mill, the HiWEDGE can provide information to the rougher control to minimize camber and to clearly identify any profile shape change.
