This article presents an overview of a revamping project conducted by Danieli Centro Combustion at the Vallourec do Brasil Belo Horizonte plant, including technical features of the new pipe preheating furnace, and describes the decision-making process used to identify the best configuration in terms of energy recovery, process and product quality.
This article discusses a new laying head technology developed by Primetals Technologies that produces a consistent ring pattern at high speeds, with significantly improved pipe life. The technology employs a self-regenerating process during rolling that shifts the wear zone without affecting laying head dynamic balance.
Though the fraction of steel produced through the ingot casting route has decreased, steel for some special applications can be produced only by this process. Because of the highly critical nature of the ingot’s end use, these ingots must meet stringent cleanliness requirements. In this part of the work, fluid flow, particle transport and solidification modeling in the mold have been performed to understand the transport behavior of exogenous inclusions during teeming.
