Abstract
It is established that addition of nano-dispersed iron oxide pigment in an amount of 0.25 – 0.50% provides intentional control of the chemisorption reaction of binder and filler during mixing facilitating an increase in carbon refractory density. It is shown that during addition of nano-additive to a carbon composition it is necessary to adjust the weight for binder in the direction of a reduction in its content. The principle of selecting the optimum binder content as a result of the plastifying effect of nano-dispersed iron oxide pigment for maximum torsional moment in the mixer shaft corresponds to a high level of expended mechanical energy and correspondingly intensification of the mixing process, and also provides an increase in mix sintering capacity during firing.
