This roll change need can be reduced enhancing mechanical and tribological properties on the surface by the deposition of chromium thin layers. This study evaluated the campaign of tool steel rolling mill rolls with chrome plating comparing to the results of uncoated cylinders.
Making "digital twins" for rolling processes and mill equipment should begin with the development of mathematical models of the deformation zone. The deformation zone of two-high flat mill rolling have been studied in detail, relevant models are available in many academic papers. However, the same cannot be said about the most complex deformation zones in …
Temperature dependent mechanical properties of AISI H11 steel are used. Thermal and mechanical stresses produced in the work rolls during hot rolling process are predicted using a thermoplastic finite element approach in the ABAQUS Standard software. Hot rolling is compared with cold rolling to determine the effects produced on the work rolls.
Hot rolling is an important steel production process. Rolls in a hot rolling mill cost significantly and influence quality of products. Wear is a major factor of roll fault. So, it is very important to study roll wear at high temperature, although roll wear study in a real rolling mill is very difficult, especially for a hot rolling mill. To meet the need of practical production for the ...
In this paper, the research is based on 1700 mm hot strip mills production line of Ansteel in China. Process variables consist of roll gap, rolling force and roll bending force (the first stand has no roll-bending force) of seven stands. There are 20 process variables together.

The new mathematical models have been applied into the temper rolling of 2050 hot rolling mills with good results. Comparison of calculated values and testing values for nine typical products has been given. The result shows that the calculated value of rolling force of temper mill is accurate.
Efficient and uniform heat removal by water spray without cracking or deforming steel slabs is a major challenge during continuous casting. With the aid of computational fluid dynamics (CFD), the current study presents a numerical model of spray cooling for process understanding and improvement.
electrical steel strip on the profile and flatness of strip is studied. Simulation results show that the strip edge tempera-ture drop has great effect on hot rolling process of electrical steel strip.
An essential reason for the rapid advance of continuous casting methods in steel-making is the capability of producing slabs, blooms or billets, as a "strand" directly from the melt. This universal method offers great advantages over former casting and rolling of single ingots; advantages are: fewer phases of operation, higher output of raw ...

STEEL 2008 168 Advanced single and multi-drive systems for plate rolling mills The ACS 6000 medium voltage AC drive is designed to meet the specific challenges faced by plate mills; namely rapid torque and load changes, cyclic loads and fast alteration between driving, reversing and braking over a wide …
For specific slab, rolling length, processing time, and power consumption can be obtained by the hot rolling process control system in steel mill. The penalties caused by jumps between adjacent slabs in width, gauge, and hardness are adopted by referring to . The data in Table 2 are actually performed TOU electricity tariffs in steel mill ...
Steel is the material of choice for a large number and very diverse industrial applications. Surface qualities along with other properties are the most important quality parameters, particularly for flat-rolled steel products. Traditional manual surface inspection procedures are awfully inadequate to ensure guaranteed quality-free surface. To ensure …
Under the background of excess capacity and energy saving in iron and steel enterprises, the hot rolling batch scheduling problem based on energy saving is a multi-objective and multi constraint optimization problem.
