Problems solved by technology
There is generally no problem with the production efficiency, heat energy utilization rate and heat treatment quality of the large-diameter well-type furnace when it is equipped with larger ring parts, but if it is used to install small-diameter ring parts, the production efficiency and heat energy utilization rate are extremely low, and the energy consumption per ton of steel cost too much
Therefore, it is necessary to increase the number of small-diameter rings in the pit furnace for heat treatment. Generally, the small rings are stacked in a large cage made of steel bars and heated in the furnace. However, due to the poor circulation of the furnace gas between the rings, the heating It is extremely uneven, the quality of heat treatment is unstable, and the rigidity of this iron cage is insufficient, the service life is low, and safety accidents are prone to occur

The invention provides an annular part heat treatment tooling applied to the technical field of annular part production and processing equipment. The tray (1) of the tooling is provided with a plurality of bottom through-holes (2), the surface of the tray (1) is provided with a plurality of support plates (3) that are arranged along the periphery of the tray (1) according to gaps, a plurality of fan-shaped gap parts (4) are formed among the support plates (3), and annular parts (5) are designed into a structure able to be placed on the support plates (3). The heat treatment tooling provided by the invention has a simple structure, can realize uniform heating during furnace charging heating of multi-pile annular parts and heating in a shaft furnace, is convenient and stable for lifting and transportation, and the whole tooling is durable in use. The tooling provided by the invention is especially suitable for the demand of heat treatment on small diameter (less than 600 mm) annular parts by a large diameter shaft furnace (with an inner diameter of less than or equal to 3m).
Description
technical field [0001] The invention belongs to the technical field of production and processing equipment for ring parts, and more specifically relates to a tooling for heat treatment of ring parts. Background technique [0002] For ring parts manufacturers, due to different customer needs, there are various types of ring parts with diameters ranging from 0.3 meters to 4 meters. Generally, heat treatment is required. Ring parts are generally heat treated in a well-type furnace, but the well-type furnace needs to adapt to large diameters. The heat treatment of the ring requires a certain distance between the furnace wall and the ring for uniform heating, so the diameter of the pit furnace is generally larger. There is generally no problem with the production efficiency, heat energy utilization rate and heat treatment quality of the large-diameter well-type furnace when it is equipped with larger ring parts, but if it is used to install small-diameter ring parts, the producti...
