According to the surface characteristics of the steel strip in the annealing furnace, the thickness of the steel plate and the contact pressure between the plates have a significant influence on the radial heat transfer of the steel coil. A multi-layer steel strip inner diameter that can truly reflect the influence factors Calculation model of equivalent thermal conductivity coefficient Through the treatment of the equivalent thermal conductivity of the radial grid interface, a mathematic model of the thermal conductivity of steel coil, which is suitable for solving non-continuous media, is established. By solving the model, The change rule of the process provides a theoretical basis for improving the measurement accuracy of the coil
