Abstract

The Chinese steel producer Rizhao Steel is now focusing on the highly attractive local and export markets for high-quality, thin-gauge strip products. The first line of five Arvedi ESP plants began operations in the spring of 2015. The new casting-rolling complex is designed for a total annual production capacity of 11 million tons of highquality, ultra-thin, hot-rolled strip products with widths of up to 1,600 mm and thicknesses down to 0.8 mm. The energy consumption and related costs are reduced by up to 45% compared with conventional casting and rolling processes. This also means a major reduction in CO2 emissions. During the project phase, the plant personnel from China received extensive training at the licensor’s plant – Acciaieria Arvedi S.p.A. in Italy – to prepare them to deliver the best operational performance with the new state-of-the-art endless casting-rolling facility. The plant setup, the training and support program, as well as the latest results from the start-up are presented in this paper.
