description The invention provides a fettling material for converters, and a preparation method and application of the fettling material. The fettling material comprises, by weight, 60-80 parts of pleonaste-containing waste bricks, 1-15 parts of waste magnesite bricks, 1-5 parts of binders, 1-15 parts of bonding agents and 1-5 parts of sintering aids. The content of MgO in each pleonaste-containing waste brick is larger than or equal to 85%, and the content of Fe2O3 is 4-8wt%. The content of MgO in each waste magnesite brick is larger than or equal to 92wt%. Compared with the prior, the fettling materialhas the advantages that the fettling material is made from raw materials in specific rations, the components well interact with one another, and the obtained fettling material has long service life, short sintering time, high flowability and high compression strength and is suitable for serving as a fireproofing material in the converters. Experiment results show that the fettling material can beused for 60 furnaces, sint
