摘 要:<正> One of the methods forming the shell is to appropriately design the cooling staves and hearth without overheating during the campaign life of the furnace. The three-dimensional steady mathematical models for calculating the temperature distribution in the coolers and two-dimensional unsteady mathematical models with phase-change latent heat for calculating the temperature distribution of the hearth bottom were established. The calculation results show that the formation of the slag-metal protection shell can be achieved by optimizing the design parameters of the coolers. Increasing the heat conductivity of the carbon brick can move the isothermal line of 1150℃ upward outside the hearth bottom.
