Abstract A mathematical model is proposed and solved for the after-decarbonization at a range of low carbon using the stochastic differential equation.Certain statisti- cal parameters of the solution process have been calculated and discussed.The reliability of the model is verified by experimental data taking the volumetric mass transfer coefficient to be a constant.The application of the model to con- trol the after-decarbonization of converter process is studied considering an exten- sion of the volumetric mass transfer coefficient into general stochastic parame- ter.
