Rotary evaporative cooling device for large ring forgings and cooling method of rotary evaporative cooling device

Abstract

The invention relates to a rotary evaporative cooling device for large ring forgings and a cooling method of the rotary evaporative cooling device. A seat ring is installed on a foundation, and a moving ring is located above the seat ring and connected with the seat ring in a rolling mode. The discharged large ring forgings after heat treatment are placed on the moving ring in an up-and-down overlaying mode, and a power mechanism driving the moving ring to rotate relative to the seat ring is arranged on the outer side of the moving ring. The large ring forgings placed on the moving ring in anoverlaying mode rotate with the moving ring, and a plurality of axial flow fans cooling the outer sides of the large ring forgings are uniformly distributed in the circumferential direction at the positions, on the peripheries of the large ring forgings, of the foundation. A pool is arranged at the position, on the inner side the large ring forgings, of the foundation, a blower is mounted on the foundation, the output end of the blower extends into the large ring forgings through an air duct, and thermal-state water vapor in the large ring forgings is carried away by air blown by the blower tocool the interiors of the large ring forgings. The rotary evaporative cooling device for the large ring forgings is simple in structure, high in bearing capacity, safe and reliable, convenient to use, high in cooling efficiency and good in cooling effect, and the product quality of the large ring forgings is guaranteed.

Description

Technical field [0001] The invention relates to a rapid cooling system after heat treatment of a large ring forging, in particular to a large ring forging rotary evaporative cooling device and a cooling method thereof. Background technique [0002] Existing large-scale ring forgings mostly adopt stack cooling after heat treatment, and axial fans are arranged around the ring stack to achieve the effect of rapid cooling. Practice has proved that the traditional cooling method used in the past is more suitable for the situation where the number of rings is small and the tonnage is small, but the production efficiency is low and multiple fan groups are required; when the number of rings is large and the tonnage is large, There will be uneven distribution of the structure inside and outside the ring, and the cooling efficiency is low, resulting in coarse grain structure inside the ring, and the mechanical properties cannot meet customer requirements. Summary of the invention [0003] ...
