The invention provides a method and
system for estimating charge surface shapes in the
blast furnace charge distribution process. The method includes the steps that the
blast furnace charge distribution process parameters, the furnace charge parameters and the charge
distribution matrix are obtained; the abscissa of the
pile cuspidal point of a charge
pile formed by the furnace charge at each chute dip angle is computed; the charge
surface shape of the furnace charge at the first-chute dip angle is computed; and according to the volume constraint that the furnace charge at each chute dip angle meets, the charge surface shapes of the furnace charge at the previous chute dip angles and the charge
surface shape of the basic charge surface, the charge
surface shape at the second-chute dip angle is obtained, charge surface shape computing is conducted in a successive iteration manner till the nth charge surface shape of all the charge surface shapes at the chute dip angles is distributed and obtained, and the
estimation result of the charge surface shapes in the
blast furnace charge distribution process is obtained. The
system comprises a collection module, an abscissas computing module, a first charge surface shape computing module and a charge surface
estimation module. According to the method and
system for estimating the charge surface shapes in the blast furnace charge distribution process, a computing basis is provided for the charge surface shapes under different charge distribution systems, precise
estimation of the charge surface shapes in a blast furnace is achieved, the charge
distribution system is adjusted in real time according to the furnace conditions, furnace charge distribution is changed, the gas
utilization rate is increased, and therefore the blast furnace can operate stably and smoothly.
