内容简介

This paper provides a summary of extended investigations performed on cement- and hydratable alumina bonded refractory materials for steel ladle purging plugs. The main wear factors of purging plugs,which are erosion due to intense stirring, corrosion by iron-oxide slag during oxygen lancing, and spalling due to thermal cycling were addressed in the investigation by theoretical thermodynamic evaluations using FactSage, mechanical property testing including hot modulus of rupture, and fracture behaviour testing using the wedge-splitting test. In addition, microstructural investigations were performed in order to explain material differences. The results provide a basis for the assessment of the different binder concepts especially for the purging plug application and indicate the potential, which hydratable alumina bonded materials could have in this area. Industrial and academic partners of the FIRE-network from three different continents have successfully cooperated in this study.
