內容簡介

Ladle shrouds（LS） and submerged entry nozzles（SEN） are flow control products used in continuous casting which transfer the liquid steel from the ladle to the tundish and further to the mould. Due to the strongly different and quickly changing temperature conditions before and during steel casting, highly thermal shock resistant refractory materials are required which simultaneously save steel process energy. A new technology embeds a special liner into the refractory body inner surface to reduce the heat transfer through the LS/SEN wall. To better understand the function of this insulation layer a mathematical model was applied. Temperature measurements carried out in the steel plant were compared with the simulation results. The research results indicate potential heat loss reduction and performance improvements in the steelmaking process.
