Steelmaking slag has been used as a road construction material, competing with natural materials. In this work, the leaching behavior of a Cr-bearing EAF slag has been studied in order to propose this kind of material to the construction market. Laboratory and industrial experimentations show that significant cooling rates are effective in order to nullify Cr leaching and guarantee the mechanical characteristics to use this slag for civil applications. |

Each year, the steel industry recycles more than 14 million tons of steel from end-of-life vehicles. This paper is a literature review on the importance of advanced high-strength steels and electronic units on the recycling of automobiles. It is supported by the AIST 2011 FeMET Design Grant program. |

The Revolution in Heat Transfer Technology
Is Won: Forced-Draft Burners Move Aside,
the Thermal Kinetic Energizer TKEnergizer™
Now Takes Center Stage

An apparatus has been developed that replaces the conventional gas burner, which in turn changes the heat transfer properties of the thermal process from radiant to kinetic. The technology is fully implemented in various batch and continuous reheat furnaces, ladle heaters and heat treatment furnaces. This paper discusses the new technology’s benefits in detail. |

Providing Secure Ground Protection
for Electric Arc Furnaces During Inrush
Conditions

The Nucor Steel–Berkeley facility
experienced sporadic tripping
of its instantaneous ground fault
protection during inrush on arc
furnaces. This paper discusses
the factors that affect inrush on
an electric arc furnace, analyzes
the topology of the power system
feeding the arc furnace at Nucor
and one of the inrush tripping
events, and discusses the steps
taken to characterize the inrush,
the associated findings, and
considerations in finding an
acceptable solution. |
