Description
Technical Field
The invention relates to a gas homogenizing mechanism, in particular to a gas homogenizing mechanism of thermal equipment, and belongs to the technical field of diffusion oxidation annealing furnaces.
Background
Diffusion annealing is also called homogenization annealing, and is a treatment method for keeping the temperature slightly lower than the solidus temperature for a long time. The chemical composition and the microstructure segregation of steel ingots, castings and billets are reduced or eliminated to be uniform. High alloy steels are more commonly used, the diffusion annealing temperature of the steel is higher than Ac3, the annealing temperature is between 1100 ℃ and 1200 ℃, and the annealing time is long and depends on the section thickness of the workpiece. Due to high temperature, long time and high cost. For steel parts, diffusion annealing does not contribute to the improvement of macro-segregation and inclusion distribution thereof. When the steel ingot is forged, rolled and heated after cogging, the heat preservation time is properly prolonged, and the effect of eliminating stress by diffusion annealing can be achieved. Most non-ferrous metals do not undergo a solid state phase change during the heating process of diffusion annealing. The problems of austenite grain refinement and steel oxidation and decarburization need to be correspondingly considered during application.
The diffusion annealing needs to be carried out on the annealing furnace, however, the existing diffusion annealing furnace has some defects:
(1) the gas flow is not uniform, reducing the performance of the process product.
