Description

Technical Field

[0001] This utility model relates to a heat treatment device for a large-megawatt planetary carrier of wind power, belonging to the field of heat treatment technology. Background Technology

[0002] As wind power products continue to upgrade, especially planetary carrier ductile iron components, the product specifications and dimensions are constantly increasing with the increase in megawattage, and the performance requirements of these products are also constantly improving.

[0003] Some types of ductile iron require normalizing treatment to transform the matrix structure into a fine pearlite structure, thereby improving the strength of the product. The quality of the heat treatment process has a significant impact on the internal microstructure and properties of ductile iron, making the heat treatment furnace, as the heat treatment equipment for the product, crucial.

[0004] Traditional heat treatment furnaces for ductile iron require manual hoisting of the castings to a rotating platform for forced air cooling after they exit the furnace, during the normalizing stage. This is inconvenient due to the high furnace temperatures (over 900℃), and the lengthy manual hoisting process, leaving the castings in a natural cooling phase, negatively impacts microstructure and performance. Furthermore, traditional ductile iron heat treatment furnaces typically consist of one furnace and one or two air-cooling rotating platforms, resulting in low production efficiency. Therefore, this application proposes a novel technical solution. Utility Model Content
