Effects of particle size distribution on the refractory properties and corrosion mechanism of ultra-low cement castables
ABSTRACT
Purpose:This study examines the effects of distribution of particle size-dimensions on refractory properties of alumina based castable refractories in which calcium aluminate cement (Secar-71) is used in low proportions as the hydraulic binder,which affects negatively properties of a refractory at high temperatures owing to its CaO content.
Design/methodology/approach:In this study the effect of particle size distribution on refractory properties of ultra-low cement castables was investigated.Secar 71 cement was used as a binder.The composition of refractory castable which consist of various particle size distribution was determined according to Andreasen packing model,with distribution coefficient (q) of 0.21,0.22,0.23,0.24,0.25 and 0.26.A cold crushing strength (CCS) of 93 MPa,a porosity value of 16.4% and a bulk density value of 3.12 g/cm3 were obtained via a distribution coefficient of 0.26.
Findings:The mechanism of slag penetration on ULC for steel ladle was examined and the penetration layer was chemically analysed.Effects of mechanical properties on the corrosion mechanism were discussed.
Research limitations/implications:Determination of effects of particle size distribustion on the refractory properties and corrosion mechanizm of ultra-low cement castables.
Originality/value:The effects of particle size distribustion on the refractory properties and corrosion mechanizm of ultra-low cement castables were investoigated.
Keywords:Ultra-low cement castables (ULC); Particle size distribution; Rheolology; Slag penetration
