In order to obtain seamless steel pipes of smaller size and better quality, it is necessary to adopt cold rolling, cold drawing or a combination of the two. Cold rolling is usually carried out in a two-roll mill, and the steel pipe is rolled in an annular hole type composed of a variable-section circular hole groove and a stationary tapered head.

Rolling force prediction is very important in hot strip rolling mill. But during the setting of rolling force in hot strip rolling mill, the rolling force signal is influenced by various factors with complicated correlation. Therefore, it is difficult to establish an accurate model to describe the rolling mechanism. In order to solve this problem, a multiple-RBF neural network model to …

Abstract. Equations are derived for the normal roll pressure, specific roll load and torque in hot rolling mills, using the condition for plastic deformation in rolling derived by Orowan, together with von Kármán's equation of equilibrium. Although applying strictly to the rolling of ideal plastic-rigid materials, these equations may be ...

This paper aims to address the issue of fluctuations of copper rod diameter during the process of hot rolling. In addition, it proposes a solution to control the diameter of the copper rod in order to improve the quality of the hot rolling mill products.

The PC mill was first used commercially for the continuous hot rolling mill of Hirohata, which was commissioned in 1984, and then for the former stands of the finishing mill train of the continuous hot rolling mill of Nagoya, and also for the finishing stand of the Kimitsu plate mill. 2.4 New rolling processes for long products

Casting and rolling. This course handles the final processes of casting and rolling to obtain the final steel products. Casting to form semi-final products is explained with the main components and their functions. Rolling processes are treated separately into hot rolling and cold rolling. Introduction and Continuous casting 13:12.

Hot Rolling Technology Rolling is classified according to the temperature of work piece rolled. If the temperature of the metal is above its recrystallization temperature, then the process is termed as hot rolling. For hot working processes, large deformation can be successively repeated, as the metal remains soft and ductile. The

Advanced high strength steels (AHSSs) for auto-making are primarily produced by rolling, plus heat treatment technologies if necessary. However, due to the metallurgical complexity of AHSSs, it is impossible to roll all of the AHSS grades in a rolling mill with the same rolling technology.

Roll wear is more severe with this type of hot-strip mill than with semi-continuous and continuous hot-strip mills. However, this disadvantage can be alleviated considerably by the use of hot-rolling lubricants. Steckel hot mills are capable …

The case study on the 1580 mm hot rolling line in WISCO plant demonstrates a successful dedusting efficiency of 93.50% on the R2 rough rolling mill. The spray pressure of 0.5 MPa and the nozzle diameter of 1.4 mm are appropriate to generating the proper water droplets with the diameter of 71.1 μm in order to capture the dust particles with the ...

The molten steel is then cooled, cast into large slabs and transferred to a hot-rolling mill. Slabs in the rolling mill are placed in a reheat furnace and heated to temperatures approximately 2300°F. The hot slab is then extracted from the furnace and squeezed by a series of rollers into a strip roughly 0.075 inch thick.

In order to control an apparatus, such as a rolling mill, a control device may use a pre-set operation pattern to generate a pre-set command signal, which is then modified. That first modification may be part of a feedback loop in set command signal, which is then modified. That first modification may be part of a feedback loop in logic.

This book is organized into five parts encompassing 25 chapters that assess the impact of research and development on steel-making technology. The opening part presents an overview of the developments in the rolling mill technology and measuring instruments.

In the rolling stage, energy is consumed in the reheating furnaces. The hot charging of slabs to the reheating furnaces of a hot strip mill, in an integrated steel plant, results in an important energy consumption reduction. At the same time, it reduces the inventory and the slab handling. However, it is a challenging task to create production schedules for both the …

Rolling equipment is roughly divided into three kinds; namely, hot rolling mills, cold rolling mills, and foil mills. Usually, rolling is performed by applying a load to the materials by forcing them vertically through a pair of work rolls. The work rolls are deformed by the high load during the rolling process.
