Titanium absorption mainly refers to the reaction with carbon, hydrogen, nitrogen and oxygen at high temperature.
Properly increasing the pouring temperature of liquid metal or alloy can improve its fluidity and filling ability.
Because of the high pouring temperature, liquid metal or alloy has strong ability to keep liquid flowing in the mold.
Therefore, for thin-walled castings or metals or alloys with poor fluidity, the pouring temperature can be appropriately increased to prevent insufficient pouring and cold preservation.
However, if the pouring temperature is too high, the liquid metal or alloy will be seriously sucked and shrunk, resulting in defects such as porosity, shrinkage cavity, shrinkage porosity, sand sticking and coarse grains.
