50 m/s in Cooling Bed to Enhance Profitability in Rebar Production
Achieving a very high production rate for the smaller-size range of bars products, in order to exploit reheating furnace capacity fully, has always been a common goal for bar producers worldwide. But one of the most common ways to reach this goal is to use the well-known Multistrand Slit Rolling system, a combination of dedicated roll-pass design and dedicated guiding equipment to shape and longitudinally separate the rolled stock into two, three or four individual strands, rolled together as one single bar down to the final finished size. The alternative technology that will result in a real breakthrough innovation for the full spectrum of steel producers worldwide, will be the ultra-high speed bar finishing rolling and delivery into the cooling bed through the Danieli HTC “High-speed Twin Channel”. This system, originally invented and patented by Danieli in the early 1970s, has been operating successfully worldwide since then with speeds that, from the original top speed of 20 m/s during those years, has now reached the record speed of 50 m/s in the cooling bed. The HTC perfectly suits the latest generation high-production bar mills where smaller-size bars are slit at the pre-finishing continuous mill stands and finished on two independent strands through two Delta-type high-speed blocks. This paper introduces the technical characteristics of the ultrahigh speed bar finishing rolling and delivery system, as well as its main highlights and benefits (…among the most significant: the possibility of producing down to 6-mm-dia rebars at very high output rates).
