Steel production figures are rising continuously year after year, and with them carbon dioxide emissions. This makes it even more important to reduce the carbon footprint in this area. One starting point is the steel refining process with the frequently used ladle arc furnaces (LAF). The LAF brings the molten steel to the temperature range required by the subsequent continuous caster. The trick now is to hit the optimum temperature in extreme ranges of more than 1,500 degrees Celsius – exactly between the current continuous temperature and the liquefaction point below which the steel begins to solidify.
"We have further developed our established CasTemp Wireless system into CasTemp Superheat precisely for this purpose, which makes it possible to stay as close as possible to the liquefaction temperature in the superheat range by measuring the current temperature and solidification point," explains George Humphrey, Research and Development Engineer at Heraeus Electro-Nite.
