Establishment method for visualizing erosion degree of hearth carbon brick

The invention discloses a hearth carbon brick erosion degree visualization establishment method. The method comprises the following steps: firstly, obtaining a carbon brick heat conductivity coefficient-temperature linear relational expression of an intact layer by using blow-in period data; then, according to the erosion change of the carbon bricks, the carbon bricks are subjected to regional division, the boundary temperature of an intact layer and an embrittlement layer is obtained through calculation by utilizing a heat conductivity coefficient-temperature linear relation and combining the heat flux equality principle, and based on the boundary temperature and the heat conductivity coefficients of the embrittlement layer and an iron permeating layer, calculation and visualization establishment of the hearth carbon brick residual thickness are carried out. According to the method, calculation is carried out based on the relation that the heat conductivity coefficient of the intact layer of the residual car
