A prediction method of silicon content in hot metal of blast furnace

Metalurgija, 2022
In blast furnace smelting, the silicon content in hot metal can indirectly reflect the blast furnace temperature and measure the quality of hot metal. For more accurate prediction, according to the reduction reaction, the input parameters affecting the ...

Simultaneous enhancement of oxidation resistance in Nb-Si based alloys at 1250 °C by GdNbTiO6 formation and microstructural refinement

Applied Surface Science Advances
The oxidation resistance and behavior of Nb-16Si-20Ti-1.5Zr-1B-1C-xGd (x = 0.05, 0.1, 0.2, 0.4 at.%) alloys at 1250 °C were investigated. A suitable Gd addition (0.2 at.%) effectively refines the microstructure. Oxidation tests reveal that the alloy with

Arabic Hot Metal [PDF]

Philological Encounters, 2018
Abstract This article investigates the beginnings of Arabic typographic composition with typesetting machinery. It discusses different claims in literature of the first instance of mechanical composition and juxtaposes them with findings from original research in archives of typesetting machinery manufacturers active at the beginning of the twentieth ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Precipitation of abundant nano-interfaces in Sc/In-doped Mg-Y-Zn alloy and the two-stage hydrogenation behavior: Enabling rapid reaction kinetics

Journal of Magnesium and Alloys
Mg-Y-Zn hydrogen storage alloy has the advantages of high capacity and good oxidation resistance. To weaken the “blocking effect” of bulk MgH2 for rapid hydrogen absorption and desorption, a novel Mg95Y2Sc1Zn1In1 alloy with α-Mg phase, eutectic phase ...

Thermal state simulation analysis of molten iron ladle based on different insulation measures

工程科学学报, 2018
The turnover time for transporting a hot metal from a blast furnace to a basic oxygen furnace is long and therefore the heat preservation effects are not ideal. These factors affect the temperature and thermal state of the ladle refractories, which leads

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...
