1, Insulation covering agent is made of low thermal conductivity material composition, such as: expanded perlite, expanded graphite.
2.In addition to the low thermal conductivity material, by adding a certain percentage of the heating material, and under the heat of the metal liquid, the oxidant provides oxygen to oxidize the reducing agent and prolong the solidification time of the metal liquid in the riser.
3.In the case of different insulation covering agent, the mouth shrinks into a "dish-shaped flat or hemispherical bottom, which is shaped like a U-shaped throat.
