By combining numerical simulation with experimental research and statistical datas from production sites, the effects of the ladle lid and thermal insulation blanket on the molten steel temperature in a 100 t ladle was investigated. Simulation results showed that, after 30 minutes of tapping, the central temperature drop of molten steel in a ladle with a lid was 17.9 ℃ lower than that without a lid. Production statistics indicated that, within 21~30 minutes after tapping, the average temperature drop of molten steel in a ladle with a lid was reduced by approximately 16.52 ℃compared to one without a lid, which demonstrated significant thermal insulation performance of the ladle lid. The results also revealed that a greater thickness of the thermal insulation blanket led to better heat preservation. At 72.32 minutes after tapping, the molten steel temperature with a 15.00 mm thickness thermal insulation blanket was 8.77 ℃ higher than that without any blanket, yielding a cost benefit of 1.26 yuan per ton.
