The fabrication and application of a new style cast copper cooling elements for blast furnaces are introduced in this paper. the cooling channel is formed by submerged copper pipes and the dovetail groove on the surface is formed in casting in one step. The liquid copper partially melts submerged copper pipe, forming an integrated block with very high contacting ratio at the interface between the pipe and cast copper. The cooling elements are featured by high thermal conductivity for cooling, high working pressure with no leakage risk and low water flow resistance. The shape of the cooling elements is flexible and is easy to fit the furnace configuration, thus used as not only the flat furnace walls but also complicated components in difficult areas. The cooling elements were installed and in operation in many blast furnaces which had volume from 2000 cubic meter to 5800 cubic meter. With its high quality, SXSG copper cooling elements guarantees the furnaces safe and reliable performance .
