Optimization of Lining Structure of Baosteel Tundish and Application of Thermal Insulation Technology
There are three forms of heat loss in the tundish of the molten steel: heat dissipation on the upper surface of the tundish,heat storage in the inner lining and conduction heat conduction through the inner lining to the outer casing.This paper intends to optimize the configuration of Baosteel tundish lining masonry structure and thermal insulation technology,and conclude a safe,stable,long-life,energy-saving and thermal insulation tundish lining refractory configuration technology to reduce the temperature drop during the tundish casting process.And temperature fluctuations,the temperature deviation of molten steel is reduced by 10.31%,the fluctuation range is narrowed,and the quality of the slab is improved.At the same time,by establishing a semi-automatic tundish refractory pouring operation production line,the refractory consumption is reduced and the labor productivity of the operators is improved.
