Abstract

Results are provided for the design of a carbon refractory structure with a pore size of less than 25 μm. It is established that if in planning the charge for carbon blocks the coarse fraction (10 – 5 mm) is excluded, converting the medium and fine fractions to 100%, then the sizes of fractions become close to those calculated by equations used traditionally describing optimum particle packing. In a three-fraction charge carbon material compositions composites are obtained within which the predominant pore size is less than 25 or even 10 mm.
