Refractory datasheets provided by the brick suppliers with detailed physio-chemical properties of the bricks, especially their thermal conductivities.Insulation layers temperature profile calculation, which gives the steel shell temperature.A complete thermal expansion calculation for RK and SCC.RK: thermal expansion in the circular direction is needed.SCC: thermal expansion in the circular direction and sections of the right side vertical wall to be provided. Optional: If the circular expansion is too important, the thermo-mechanical calculation of the outer shell for mechanical resistance verification shall be done as well.
