Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a vacuum precision casting furnace temperature measuring device. Background technique [0002] Vacuum precision casting furnace is a process test instrument used in the fields of material science and metallurgical engineering technology. Vacuum precision casting furnaces mostly adopt a vertical two-chamber or vertical three-chamber design. Both melting and casting are carried out in a vacuum atmosphere. The equipment can realize continuous casting of equiaxed, directional and single crystal castings. Under vacuum conditions, the precision casting furnace uses the principle of medium frequency induction heating to melt alloys with high active metal content such as nickel, titanium, aluminum, etc. in vacuum by using high-temperature master alloy ingots. temperature, and then quickly and accurately poured into the ceramic mold made by the lost wax method to cool and form. In this way, th...
