Abstract: Provided is a calculating and real-time monitoring method for a boundary of a blast furnace tuyere raceway including: the steps of firstly establishing a depth calculation model for the raceway, and further obtaining a calculation formula for a depth of the raceway so as to obtain a change law of the depth of the raceway; establishing a boundary model for the raceway through the depth calculation model for the raceway, and determining a calculation formula for the boundary of the raceway; obtaining modelling parameters, analyzing an impact of the modelling parameters on the boundary model, and determining main parameters that affect the boundary of the raceway; finally, solving a height of the raceway; and when the height or depth of the raceway exceeds a set range, adjusting a blast wind pressure and a blast wind volume to restore the height or depth of the raceway to a normal range.
