The UNI plus Coiler for highest performance requirements

摘要

The segment for high-strength hot strip holds huge potential on today's market. In particular pipe manufacturers have increasing demand for steel grades like API X70, X80 or X100 in large thicknesses. The production of these steel grades poses especially high demands on the downcoiler. Therefore SMS Siemag has enhanced its well-proven downcoiler design and developed a more powerful downcoiler, the UNI plus coiler. The paper presents the development of the UNI plus coiler, explains the necessary reinforcement and optimization of the mechanical, hydraulic and electrical design and discusses operational results.
