the searches were "stainless steel", "chromium-nickel alloys", and "nickel alloys". References were selected from the search results using a two-stage approach. Firstly, reference abstracts were scanned for relevance to the project and selected references were then acquired. Secondly, acquired references were read in full before being
It gets very hot inside a steel mill. The ladle metallurgical furnace depicted in Figure 1 operates in excess of 1500 °C, with this heat inevitably coming from coal, natural gas, or renewable hydrogen.The high-temperature chemical reduction of iron ore (e.g., Fe 2 O 3) to iron metal (Fe), its subsequent conversion to different kinds of steel (e.g., carbon, alloy, tool, stainless), and its ...
Steel making is an energy intensive industry. This work presents and identifies heat losses of the main components of this industry in Jordan. The heat losses are considerable and range from 17 to ...
ABSTRACT . The Secretariat of the OECD Steel Committee provides monitoring reports on crude steelmaking capacity developments on a regular basis, using a wide range of publicly available and commercial data sources. This paper presents an updated overview of
Abstract: Automated computer-vision-based defect detection has received much attention with the increasing surface quality assurance demands for the industrial manufacturing of flat steels. This article attempts to present a comprehensive survey on surface defect detection technologies by reviewing about 120 publications over the last two decades for three typical flat steel products of con ...

1. Low carbon steel or mild steel. Low carbon steel has 0.04–0.3% carbon content and is the most common grade of carbon steel. Mild steel is also considered low carbon steel as it is defined as having a low carbon content of 0.05–0.25%. Mild steel is ductile, highly …
Abstract. The conceptual design and modelling of the Calcium Assisted Steel-mill Off-gas Hydrogen (CASOH) process for the conversion of blast furnace gas (BFG) into H2-rich stream and CO2-rich stream at a large scale is discussed in this work. High temperature reactors packed with CaO- and Cu-based materials are used to remove CO2 from the ...
Galvanizing an article with a smooth and consistent surface that, however, exhibits local variations in structure and chemical composition of the steel may consequently give the impression that material suffering from a strong corrosion attack has been galvanized (Figure 6.9).Local differences of reactivity of the substrate with zinc cause the applied coating to have a so-called mixed ...
Yuxi Zhao, Weiliang Jin, in Steel Corrosion-Induced Concrete Cracking, 2016. 2.1 Introduction. Steel corrosion in any environment is an electrochemical process in which iron (Fe) is removed from the steel being corroded and is dissolved into the surrounding solution; it then appears as ferrous ions (Fe +).For steel embedded in concrete, the dissolution takes place in the limited volume of ...
