Performance and requirements of refractory materials for ladle

Ladle is to undertake the molten steel, continuous casting of the necessary equipment. Because many steel grades need to be refined in the ladle, including blast argon tempering, fine-grained alloy composition, powder refining and vacuum treatment, Ladle Permeable Brick lining working conditions worse and worse, the working environment is:

(1) The temperature of the molten steel is higher than that of the molded ladle.
(2) The residence time of the molten steel in the ladle is prolonged.
(3) Ladle liner itself volatilizes under high temperature vacuum and undergoes the stirring action of molten steel.
(4) lining to undertake the impact of the role of steel received.
(5) slag erosion of the lining.

Therefore, the requirements for ladle refractory are:
(1) high temperature, can withstand high temperature molten steel for a long time without melting softening.
(2) heat shock, can be repeated to withstand the installation of molten steel, without cracking peeling.
(3) resistance to slag erosion, can withstand slag and slag basicity changes on the erosion of the lining.
(4) has sufficient high temperature mechanical strength, can withstand the stirring and erosion of molten steel.
(5) lining has a certain expansion of the role of high-temperature molten steel, so close contact between the liner into a whole.
