Abstract (en)

[origin: WO7900431A1] To improve the resistance to abrasion during use of cooled components, such as tuyeres and stack and bosh coolers, in furnaces a refractory or a metal with greater abrasion resistance than the metal, which is normally copper or copper alloy, used for the main body of the component is introduced during casting into the cast walls of the components. The added material may be in the form of one or more segments, a mesh, or in discrete particles and is located at or just below the surface at the nose (24) of the component. Examples of the materials which may be used are particles (44, 48) of so-called "hard metals" which comprise hard sintered carbides, such as tungsten carbide; stainless steel meshes and expanded elements (10, 40, 42) of varying thickness; and various compressed refractories capable of withstanding the thermal shock in a matrix of copper.
