| description | The invention relates to a melting loss resistant blast furnace tuyere small sleeve and a method for improving melting loss resistance of the tuyere small sleeve. A protective coating of a high-entropy alloy system is formed on the surface of the tuyere small sleeve, and the material components of the protective coating are TiAlMoNbWSix, 0 lt, 0 lt, 0 lt, 0 lt, 0 lt, 0 lt, 0 lt, 0 lt, 0 lt, 0 lt, 0 lt, 0 lt X < = 1; and an amorphous phase structure exists in the material of the protective coating. The melting loss resistance of the tuyere small sleeve is improved by forming a protective coating of a high-entropy alloy system on the surface of the tuyere small sleeve, refractory elements Mo, Nb and W are selected as base elements in a material system of the coating, the atomic size difference is small, and a simple solid solution structure is easily formed; al can stabilize a solid solution phase structure and has excellent thermal stability, and Ti is high in specific strength and good in corrosion resistance |
