Temperature is 100 ~ 300 DEG C, and baking time is 2 ~ 3h, is conducive to rapid shaping.
Based on above-mentioned, it is an advantage of the current invention that the present invention is by carbon black, graphite powder, pitch, magnesia powder, Lauxite
With waterglass according to carbon black 25 ~ 50%, graphite powder 5 ~ 20%, pitch 2 ~ 10%, magnesia powder 2 ~ 10%, Lauxite 0.5 ~
5% and waterglass 40 ~ 50% ratio prepare, stored；Sodium silicate dissolving is obtained into raw material crude liquid, then toward raw material crude liquid
Middle addition carbon black obtains qualified water glass solution after filtering；Obtained water glass solution is mixed with the concentrated sulfuric acid, after reaction
To carbon black crude product, reaction temperature is 80 ~ 95 DEG C, and the reaction time is 90 ~ 110min；Obtained carbon black crude product is pressed
Filter, washing and mashing obtain carbon black finished product after dry, washing is washed using 25 ~ 40 DEG C of water, until the electricity in washes
Conductance is lower than 2.0ms/cm；Carbon black finished product is put into ball mill, starts ball mill, then Lauxite is poured into ball mill
In, co-grinding is carried out, grinding time 30min obtains mixed-powder product；Mixed-powder product is poured into blender,
Graphite powder, pitch and magnesia powder are successively poured into blender again, start blender, mixing time 30min, revolving speed is
60r/min；Raw material after stirring is poured into the pressure mould that pressure is 15 ~ 25Mpa, is formed in a mold, after molding again
Through overbaking；Using carbon black 25 ~ 50%, graphite powder 5 ~ 20%, pitch 2 ~ 10%, magnesia powder 2 ~ 10%, Lauxite 0.5 ~
5% and waterglass 40 ~ 50% as formula material, manufactured finished material has that resistivity is big, heat resistance is strong, while can be effective
The high-temperature gasification for reducing material, can effectively reduce the intrusion and infiltration of liquid metal；Sodium silicate dissolving is obtained into raw material crude liquid, so
Carbon black is added into raw material crude liquid afterwards, qualified water glass solution is obtained after filtering, by obtained water glass solution and the concentrated sulfuric acid
Mixing obtains carbon black crude product after reaction, reaction temperature is 80 ~ 95 DEG C, and the reaction time is 90 ~ 110min, to obtained carbon black
Crude product carries out filters pressing, washing and mashing, carbon black finished product is obtained after dry, washing is washed using 25 ~ 40 DEG C of water, until washing
The conductivity in waste water is washed lower than 2.0ms/cm, which is conducive to make the purity of waterglass more to increase, and is later period carbon black finished product
The purity for being mixed to prepare material with other raw materials is higher.
