长期以来,我国复二重线材轧机主要生产φ6.5mm以上的线材产品,而φ6mm以下的线材产品很少生产。国外φ6mm以下的线材产品主要是用高速无扭线材轧机生产。山东淄博钢厂半连续线材车间是移地新建的年产10×10~4t线材车间,其特点是,除φ500×1三辊开坯轧机以外,其余轧机均为短应力线轧机。粗轧机组为 For a long time, China’s complex double wire rod mill mainly produces φ6.5mm wire products, and φ6mm less wire products rarely produced. Foreign φ6mm below the wire products are mainly high-speed non-twisted wire rod mill production. The semi-continuous wire workshop of Shandong Zibo Steel Mills is a newly-built 10 × 10 ~ 4t wire workshop relocated. Its features are that all of the remaining mills except the φ500 × 1 three-roll open-billet rolling mill are short stress line rolling mills. Rough mill unit
