Investigation of the influence of the amount of ethylsilicate, sol based on it and phenol-formaldehyde resin on the strength properties of non-pergarnic magnesia carbon refractories

Using the full factorial experiment, the influence of the number of modifiers: ethylsilicate (Z1 = 0.5 − 1.5 %), sol based on it (Z2 = 0.25 − 0.75 %) and liquid phenol formaldehyde resin (Z3 = 3.0 − 4.0 %) on the strength of periclase-carbonaceous materials. It has been established that in order to obtain strong non-perliquid periclase-carbon refractories, the maximum amount of phenol-formaldehyde resin (4 %), ethylsilicate (1.5 %) and the minimum amount of sol based on ethylsilicate (0.25 %) should be included in the charge composition.
