Free Download Electric Arc Furnace Steelmaking with Submerged Mixed Injection English | 2024 | ISBN: 9819946018 | 161 Pages | PDF EPUB (True) | 42 MB This book focuses on the study of electric arc furnace (EAF) steelmaking with submerged injection. The new EAF process with submerged mixed injection was first proposed and applied by the authors. It analyzes the mechanism of submerged O2-CaO and carbon powder injection, the impact characteristics of submerged gas-solid injection and the fluid flow characteristics of EAF molten bath with submerged gas-solid injection. The industrial application of EAF steelmaking with submerged gas-solid injection was introduced. Finally, the book reviews the recent innovations and advances of injection metallurgy in EAF steelmaking. It also proposes a possible future process for cyclic utilization of CO2 in EAF-LF steelmaking process. This book provides basic data support for the industrial application of EAF steelmaking with submerged mixed injection for researchers, engineering and technical personnel and industrial professionals.
Free Download Dr. Hans Peeters, "Resurfacing the Submerged Past: Prehistoric Archaeology and Landscapes of the Flevoland Polders, the Netherlands" English | ISBN: 9464260394 | 2021 | 310 pages | PDF | 38 MB The Netherlands are internationally renowned for the archaeology of its wetland environments. The reclamation of the Flevoland Polders in the early half of the 20th century not only exposed hundreds of shipwrecks, but also remnants of prehistoric landscapes and traces of human occupation dating to Mesolithic and Neolithic times. Ultimately, this led to the 'discovery' of the Swifterbant Culture in the 1960s-1970s, and which was initially seen as a Dutch equivalent of the Ertebølle Culture.

Allen Narrator: Stephen Bowlby Most books gloss over submarines at Midway and, if they are mentioned at all, conclude they failed miserably and had little impact on the outcome of the battle. It is undeniable that carrier aviation and intelligence saved the day, but the role of the submarine was an important one in defense of an anticipated amphibious assault. Midway Submerged is a comprehensive examination of a little-known aspect of this pivotal naval battle, explaining how Nimitz used his submarines at Midway and the Japanese misused theirs based on a flawed tactical plan.
