hot rolling mills. The demands related to the capabilities of a conventional hot rolling mill have changed in the last years. In addition to the high level of output and productivity, the demand for quality improvement is still growing up. Safety and energy saving become a very important aspect. Today there is a clear trend in developing new steel

2.1 Experimental set up. A Hille-100 rolling mill with rolls of 225 mm diameter and 254 mm length, driven by a variable speed DC motor of 75 horse power, was used. The maximum rolling force, torque and speed are 1500kN, 13kN-m and 70 rpm respectively. The sensor roll nitrided surface hardness is 65 to 70 HRC. The diameter of the top and bottom ...

A Comprehensive Guide to Hot Rolling Mill Process. The main objective of the entire steel rolling process is to create complete or semi-complete parts by deforming the massive plates and ingots to decrease the cross section in them. In metalworking processes, hot rolling mill is considered to be a commonly-used technique.

Hot rolling mills typically produce sections of steel at various dimensions from billets of steel. The manufactoring process involves passing bars of steel at high temperatures. This happens through rotating rolls to reduce the thickness and shape the sections. It furthers proceeds into cooling and cutting to length or coiling into rolls for ...

As shown in Figure 4, M 1, M 2, and M 3 are the equivalent mass of the upper part of mill stand, backup roll, and work roll. J 1 and J 2 are the rotational inertia of electrical machinery and upper rolls system of the rolling mill. K 1, K 2, K 3, and K 4 are the equivalent vertical stiffness. Based on Duffing theory, is the equivalent horizontal stiffness …

production scheduling on the hot rolling mill. 2. HOT ROLLING 2.1 The process The hot strip m ill typically consists of several processing stages (reheating furnace, roughing …

Hot rolling is a metalworking process in which metal is heated above the recrystallization temperature to plastically deform it in the working or rolling operation. This process is used to create shapes with the desired geometrical dimensions and material properties while maintaining the same volume of metal. The hot metal is passed between …

The mechanism of the position-mode side guide in correcting slab centerline profile and camber in the roughing process of a hot strip mill (HSM) was analyzed using finite element simulation. The finite element model was established based on the actual size of the roughing mill and on the actual actuating time sequence of the roughing mill in …

production scheduling on the hot rolling mill. 2. HOT ROLLING 2.1 The process The hot strip m ill typically consists of several processing stages (reheating furnace, roughing mill, finishing mill, down coiler), on which the slabs need to be processed sequentially ; see e.g. Lenhard, J.G (2007) and Ginzburg V.B. and Ballas R.

The conversion allows the standard 4-high rolling mill design to roll lighter gauges without the many deficiencies of a 4-high rolling mill. Our current equipment include: 26" x 72" 2-High w/Roll Bend. 3.5" x 16" x 20" American 4-High w/Terminal Equipment. 16" x 20" x 48" 4-High 2/3,000 HP DC Drives.

More high-quality output with optimized solutions for hot rolling mills. Despite the everyday challenges of heat, lots of cooling water and high-impact forces, hot rolling mills are expected to continuously increase output while maintaining and improving the quality of the finished product. But producing new, higher-quality steels often require ...

Extensometers for Hot Rolling Mills. In a hot rolling mill, the extensometers are fixed by mounting on two studs/posts that are precision welded to the sides of the mill stand. The E4 extensometers are protected by a round stainless steel housing and connected via a 4-core high temperature cable with protective sleeving to a local junction box ...

Based on the analysis of the influence of roll vibration on the elastoplastic deformation state of a workpiece in a rolling process, a dynamic rolling force model with the hysteresis effect is established. Taking the rolling parameters of a 1780 mm hot rolling mill as an example, we analyzed the hysteresis between the dynamic rolling force and …

The X-Roll® hot strip mill from SMS group is an all-round talent in hot strip production. It is the proper solution for ultra-thin gauges up to thick gauges for all steel grades incl. LC, ULC, high strength grades, API grades. ... Our hot rolling mills are capable of producing flat steel from thin gauges of 1.2 mm to high-strength steels up to ...

The rolling of thin aluminum foil is a very specific process and differs from conventional cold rolling. This rolling mode is reached at thicknesses below app. 70 μm. With decreasing strip thickness, the specific roll force increases, which leads to an increasing elastic work roll flattening in the contact zone.

Hot Rolling of Aluminium1. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 11.6 Summary. Hot rolling is one of the most common and cost-effective techniques to convert aluminium cast slab to flat sheet down to 2 mm thickness, which becomes the starting stock for cold rolling. Hot rolling is one of the most important manufacturing …

The function of the hot rolling mill is based upon the simple mechanism of using rolls to press steel slabs and reduce their thickness, as illustrated in Fig. 3. Before slabs can be rolled into hot rolling mills, slabs should be heated to the deformation temperature using reheating furnaces. Achieving this heating temperature is a major ...
