The effect of nanodispersed iron oxide additives on the formation of the density of carbon refractories
It was established that the addition of nanodispersed iron oxide pigment in an amount of 0,25‒0,50 % provides directional regulation of the chemisorption interaction of the binder and fller during mixing, contributing to an increase in the density of carbon refractories. It is shown that when introducing nano-additives into the carbon composition, it is necessary to adjust the mass of the binder in the direction of reducing its content. The principle of selecting the optimal binder content as a result of the plasticizing effect of nanodispersed iron oxide pigment at the maximum torque on the mixer shaft corresponds to a high level of expended mechanical energy and, accordingly, to intensify the mixing process and provides an increase in the sintering mass during fring.Ill.5.
