Description
Technical Field
The invention relates to the field of molds, in particular to a casting mold for casting an ultrahigh-temperature metal piece.
Background
The large forging is used as a core part of large complete equipment in the fields of metallurgical machinery, petrochemical industry, transportation, energy, power and the like, plays an extremely important role in national economic construction, national defense equipment and major scientific devices, and the production capacity and the quality level of the large forging are important marks for measuring the national independent capacity and the national strength. Therefore, the method has very important significance for improving the internal quality of the large forging and ensuring the safety and reliability of the large forging in the operation process.
Large grains are generally caused by an excessively high initial forging temperature and an insufficient degree of deformation, or an excessively high final forging temperature, or a degree of deformation falling within the critical deformation region. The aluminum alloy has too large deformation degree to form texture; the deformation temperature of the high-temperature alloy is too low, coarse grains can be caused when a mixed deformation structure is formed, the plasticity and the toughness of the forging are reduced due to the coarse grains, and the fatigue performance is obviously reduced. After forging, the cooling is too fast, and the softening caused by recrystallization may not keep up with the strengthening (hardening) caused by deformation, so that the cold deformation structure is partially remained in the forging after hot forging. The presence of this structure increases the strength and hardness of the forging, but decreases the plasticity and toughness. Severe cold hardening phenomena may cause forging cracks.
The uniformly heated forging die can not be guaranteed when the existing forging die is cooled, and the cooling die is cooled too fast without protection measures, so that the die can be guaranteed to be uniformly cooled in the cooling process, and rapid temperature change can not occur in the cooling process.
