AB - This paper describes a method for manufacturing a high-temperature heating unit. We used graphite powder GSP-50 as a filler and sugar as a binder. The filler and binder were taken in the ratio 6 : 1. In manufacturing the heater, a paper shell is used to make a tubular preform. The paper mold is filled with a mixture of graphite and sugar and then compacted using a shaking table to density ρ = = 1.185 g/cm3. The unburned compacted preform is placed into a pyrolysis unit to be calcined at 900°C for 6 h. Subsequently, the carbonized preform is saturated in the pyrolysis chamber at 970°C for 48 h to density ρ = 1.175 g/cm3. The carbon–carbon heater unit produced in this way reduces the time for manufacturing the heater by one order of magnitude, decreases the consumption of electricity, natural gas, and carbon materials, and significantly increases the life of the heater. This method is suitable not only for the manufacture of heating units but also for other products having a hollow cylindrical shape for nuclear, aviation, and space industries.
