摘要: Equations commonly used in describing reaction kinetics are examined and the problem of applying such equations to transient processes is discussed. Three examples phenomena detail. It shown that for carbon injection into slag, can be described by employing data oxidation CO/CO2 assuming conditions approximately halfway between those equilibrium with slag carbon. demonstrated that, when time averaged interfacial area employed, rate iron-aluminum alloys a single first order equation, accommodating 300% change area. Creation surface oxygen steelmaking discussed method determine size distribution droplets generated proposed. concluded changes during complicate analysis kinetics. However, it should possible develop quantitative kinetic models describe real processes.
