EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

The flat steel feed stock for final fabrication of steel products is mainly covered by cold rolled and final annealed or galvanized strips. Depending on the thickness and surface demands, also conventional batch processes can serve a certain but truly very limited ratio. The Arvedi ESP Technology is giving new impulses into this market. With this game changing technology it is suddenly...

Si bearing automotive steels manufactured from the Compact Strip Production (CSP) are used for making the surface critical Wheel & Rim application. A lot of scale issues are encountered in these grades making it very difficult to meet the urgent needs of the customer and it also leads to a lot of downgrading at Tata Steel’s premises. A cross functional project was undertaken at Tata Steel’s...

Due the increasing requirements for an integrated system for dimensional measuring and defect detection, Danieli Automation has recently developed an innovative defect detection algorithm. Based on the data grabbed by the same high speed cameras also used for profile dimensional control, it builds a complete production quality assurance package. A high density and accurate 3D surface of the...

POSCO has developed CEM® (Compact Endless cast and rolling Mill) process, which is based on high casting speed with 6~8m/min and endless rolling from mold meniscus to down coiler. Mechanical design improvement and high speed technology development have been achieved through various efforts such as the mold pool flow control, water cooling in the caster and the mold level hunting control. For...

Over the last 25 years the thin slab casting and rolling process has been gaining a major market share in the production of hot rolled strip, progressively eroding the areas previously of exclusive domain of conventional mills. This is mainly thanks to the competitiveness of the process over conventional ones, and to the growing ability of this technology to cover the majority of market...

Strip biting is considered the most critical moment for hot rolling. Rolling could be done only if it is succeeded; otherwise the strip cannot be threaded into the mill stand and cobble will be happened due to material accumulation. The possibility of having such problem will be increased while using RGL (Roll Gap Lubrication) during the strip head biting. Based on an empirical experience,...

Since the end of the 1980s, thin slab casting and rolling plants, in particular CSP® plants are well established for the production of hot strip. By introducing the endless operation mode, a new generation of casting and rolling plants was created. CEM®, the compact endless casting and rolling mill, is the innovative solution introduced to the market by the Korean steelmaker POSCO and the...

For every single final product you can get a carbon foot print, which is dominated by raw materials and production processes. The steel industry is looking to minimize its carbon footprint by self-defining reasons not only for environmental aspects, but also to cut own energy costs. There were significant results reached by optimizing each process step and also in trying to link single process...
