SOME FEATURES OF MILLS OPERATION COLD PILER PIPE ROLLING

Improved Drive Control for Multi-Stand Cold Rolling Mills

In multi-stand cold rolling mills an accurate synchronization of the mill drives is necessary for a good product quality and for a safe process operation. During the standard commissioning procedure the control performance of each drive is optimized individually. However, in normal operation mode the performance is then not always optimal due to the coupling of the drives by the strip being rol...

Rolling mill simulator A new platform for testing, analysis and optimization of cold rolling mills

The cold rolling of flat metal products especially in tandem or multi-stand mills is a highly complex process where the product quality is influenced by various aspects. With the help of a hardware-in-the-loop simulator, the complete rolling process can be simulated and tested in real-time. This allows pre-commissioning and pre-optimizations before the actual commissioning work is done on the p...

A comparison of two set-up generation systems for cold rolling mills

Set-up generation is an important aspect in the operation of tandem cold mills. It defines speeds and powers for the drives, stand reductions, roll forces and interstand tensions for the tandem cold mill control system. Set-up optimization should lead to improved thickness regularity, surface finish and shape performance of the strip. The importance of such optimization first appeared in (1) an...

Reeling Mechanism for Wire Rod Rolling Mills

assessment of indoor airborne pollutants of beam rolling mills factory

air pollutants from iron and steel making operations have historically been an environmental concern. the factory located at ahwaz, iran, has two production lines namely, 630 and 650, which produce iron parallel edge. the objective of the study is to determine indoor respiratory particulate matter (rpm) and feo concentrations and their comparison with niosh standards. this is a cross–sectiona...
