Periclase-Carbon Refractory Properties with a Different Amount of Graphite in the Charge Using Liquid PFR and Graphite as Modifiers

详细

Results

are given for a study of the effect of introducing different amounts of graphite modified PFR and graphite into a periclase-carbon (PC) refractory charge based on fuzed periclase. The PFR modifier used is ÉTS-40, and the graphite modifier is a sol based on ÉTS-40 hydrolysate and 20% NiCl₂ solution. A production scheme is proposed for preparing PC-refractories with combined modification of components, and also a charge composition with 15 – 20% graphite demonstrating sufficiently good slag resistance.
