The information of High thermal conductivity carbon bricks

High thermal conductivity carbon bricks
Carbon bricks: anthracite and coal tar over coke or heat in the reducing flame firing a neutral refractories. The carbon content of about 88% -90%. With high thermal stability, refractoriness, thermal conductivity and electrical conductivity. Molten metal and slag erosion resistant, but susceptible to oxidation. Mainly used for the molten metal and furnaces and stoves, body contact, such as the furnace and the bottom of the blast furnace, molten non-ferrous metal shaft furnace, fused calcium carbide, ferroalloy electric furnace.
Blast furnace carbon brick of high thermal conductivity and its manufacturing method
: A blast furnace with high thermal conductivity carbon brick, the ratio of raw materials (by weight) 20 to 24 percent of the binder, the graphitization process of the graphite pieces 40 to 50 percent, the roasting process, roasting pieces 25 to 37 %, non-carbonaceous additive 1 to 3 percent.
High thermal conductivity carbon bricks Description: The present invention is mainly related to a blast furnace with carbon refractories and their manufacturing methods, in particular, relates to a suitable do blast furnace bottom lining of the high thermal conductivity carbon brick and its manufacturing method. A blast furnace carbon brick of high thermal conductivity, the ratio of raw materials (by weight) 20 to 24 percent of the binder, the graphitization process of the graphite pieces 40 to 50 percent, from 25 to 37 percent of the roasting process, roasting broken, non-carbonaceous additives 1-3%. The main raw material can use the processes of the carbon factory substandard goods, not calcined, eliminating the need for raw material calcining processes, Carbon Works rational use of resources, save energy and reduce costs. The aggregate used in a large number of graphite broken, the thermal conductivity of the carbon brick to 30W/mK (600 ° C), will help strengthen the bottom cooling effect, extend the life of a blast furnace.
