Sustained molten steel/concrete interactions tests
Abstract
Four tests of the sustained interaction between high-temperature steel melts and two varieties of concrete are described. Inductive heating was used to keep the 200Kg stainless steel melts liquid for periods of up to 20 min. Measurements of the gas composition, gas temperature, gas generation rate, aerosol emissions, upward heat-flux from the melt, and melt-temperature were made. Gases liberated from the concrete were found to be chemically reduced principally to carbon monoxide and hydrogen as they passed through the melt. The tests provided some evidence that stainless steel may also catalyze the hydrogenation of carbon monoxide to yield hydrocarbons such as methane, ethene, and ethane in the gas stream. The hydrogen/carbon ratio in the gases was not the same as the ratio in the concrete.
