        Carbon calciner is a kind of heat treatment equipment for carbon materials, including rotary type and autoclave type. The selection of refractories for the two furnace types is also different.
        Autoclave calciner is a kind of calciner that indirectly heats carbon materials by burning in the fire channel. The lining of the fire passage is made of silica brick with good thermal conductivity and high load softening point. Calcining pot furnace is a kind of heat exchange furnace. The lining material of the exchange furnace is special clay brick with low porosity, and the combustion port is wear-resistant castable.
        Electrode baking furnace is a multi chamber baking furnace. Because the bottom of the roaster bears the upper weight load and high temperature attack, special clay brick is selected as the lining, but general clay brick is not.
        Carbon calciner is a kind of equipment for heat treatment of carbon materials in isolated air. Heat treatment process can make carbon materials obtain better oxidation resistance and corrosion resistance. The autoclave calciner for carbon calcination is composed of four small calciners. The autoclave calciner makes full use of carbon materials to supplement part of furnace gas in the calcination process, and burns in the fire channel. The fire channel temperature is 1300-1380 ℃. The silica brick used for the fire path of calciner should be subjected to high temperature, the impact of carbon loading and discharging materials on the tank wall, the erosion of combustion gas and the serious erosion of molten slag.
        Due to the use conditions, the lining material of calciner and fire channel is silica brick. Due to the high temperature at the combustion port, high alumina brick is used for masonry, and red brick and light insulation brick are used at the bottom of the furnace.
        Refractory materials for carbon calciner are mainly clay brick with high load softening, silicon brick with high temperature resistance, light insulation brick and wear-resistant castable.
