Abstract：
In order to control the production cost,the original composite reflective adiabatic plate was replaced by a new type of aerogel insulation board.Based on heat transfer principle and finite element analysis technology,the thermal insulation effect of low carbon steel SPHC was tested.The mathematical heat transfer model of ladle wall temperature field was established by ANSYS software,and the temperature of ladle shell was studied by steady-state analysis method.The finite element analysis results were verified by measuring the temperature of the ladle shell with an infrared temperature measuring gun.The results show that compared with the original ladle,the finite element calculation of the ladle shell temperature decreases by 67℃after using the new type of aerogel adiabatic sheet ladle,the measured ladle wall temperature decreases by 69℃on average,and the average calculation error is 2.99%.Ladle reduces molten steel temperature loss by 9.88℃in one working cycle,and reduces cost by 2.7 RMB/ton of steel,achieving remarkable economic benefits.
