Danieli Universal Endless (DUE) The new evolution of Danieli Thin Slab Casting and Rolling Plant
By Alessandro Pigani, Paolo Bobig, Mike Knights, Danieli & C. Officine Meccaniche S.p.A., Italy; Stefano Martinis, Danieli Automation S.p.A., Italy

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 niches, well beyond the boundaries of the commodity market. After having significantly contributed to the continuous expansion of this production mode and after an extensive campaign of theoretical research and physical testing in reference plants, Danieli has progressively developed over the years a new generation of thin slab casting and rolling layout, marking a new phase in the evolution of this process.

World’s first application of new idRHa+ rail hardening technology in Baogang Rail Mill
By Y. Zou, Y. Wang (Baotou Iron & Steel Co. Ltd – Rail Mills - P.R.O.C.) A. Lainati, F. Pegorin, (Primetals Technologies - Italy) A. Saccocci, A. Mazzarano (RINA Centro Sviluppo Materiali - Italy)

In late 2013, the installation of the world’s first application of a break-through technology for rail hardening was started at Baogang Iron & Steel (Group) Co. Ltd. in Inner Mongolia, China, one of world’s leading rail producers. The “Injector Dual-phase Rail Hardening” (idRHa+) system was developed by Primetals Technologies and Centro Sviluppo Materiali S.p.A. (RINA-CSM) a Technical Center headquartered in Rome, Italy. Baogang was a key partner, providing its large expertise of premium-rail producer, including its experience with existing offline technologies. With a design based on thermal, mechanical and metallurgical models, idRHa+ can apply customized cooling protocols, so to obtain the desired microstructure and hardness distribution across the rail head, with a high degree of accurateness and operation flexibility. idRHa+ can be installed in inline or offline configurations. During 2014, the system was successfully commissioned at rail mill #2 in the city of Baotou, Inner Mongolia, and entered the regular commercial production. This paper gives an overview of the key concepts behind idRHa+’s design, the progression of its commissioning and testing till the ramp-up to consistent industrial operation.

From the caster to the rolling mill – transport, inspection, conditioning and treatment of cast products
By P. Wieser, S. Hahn, F. Wimmer, B. Winkler-Ebner, D. Burzic, Primetals Technologies, Austria

The handling, storage and treatment of slabs, blooms, billets, and beam blanks after casting as well as their preparation for the rolling process is a challenging procedure in metallurgical plants. The hot strand leaving the casting machine – typically with a surface temperatures ranging from 800° Celsius to 1,100° Celsius – must be cut, marked, inspected, and if necessary conditioned. In the case of hot charging to the rolling mill, heat loss from the cast product must be minimized to reduce energy consumption in the reheating furnace. For several steel grades, special ambient conditions (for example, heat insulation) are required during the cooling process.

Mill Ladle Refractory Monitoring
By Our News Bureau

Steel Mill Ladle have limited lives. As their refractory tining wear or develop breaks due to shock, the outlet part of a ladle can be exposed to excessive temperature,If not cought in time, the result can be ladle disintegration and a molten metal breakout, threatening the lives of workers and destroying equipment. FLIR thermal imaging camera systems are used to monitor ladles in real time and warm of a breakout before it happens, saving hundreds of thousands of dollers by preventing injuries, equipment damage, and production downtime.

Compact, chip-repellent design: the new R2.40 plastic energy tube from igus
By Our News Bureau

At the Motek and at the EMO, igus is presenting the energy tube series R2 with 40 millimetre inner height, which offers the right solution for compact installation spaces such as in machine tools. Like its big brother, R2.75 with 75 millimetres interior height, the new energy tube provides users with protection against chips, dust and dirt. At the same time it is easy to open and close, making assembly work very simple.
