Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation equipment, in particular to a slow cooling and heat preservation device for a quenched water ball. Background Art

[0002] Steel balls are widely used. Their production process includes cutting, heating, forging, heat treatment, testing, packaging and warehousing of raw materials (steel bars). Quenching is an important part of the process flow of heat treatment for steel ball production. Heat preservation after quenching of steel balls is a very important process. It is a process of heating and heat preservation of metal materials in a high temperature environment after quenching of steel balls. The heat preservation time is generally from several hours to dozens of hours, which can promote the recrystallization of materials and improve their mechanical properties. The specific functions mainly include the following points: 1. Fixing grains. After quenching, the grains in metal materials often change. Heat preservation can restore the stable state of grains and avoid grain growth and deformation. 2. Avoid cracking. During the quenching process, metal materials are prone to adverse effects such as stress increase and deformation, and heat preservation can alleviate these effects and prevent problems such as cracking and rupture. 3. Improve mechanical strength. Heat preservation at high temperature can promote the recrystallization of grains and the evolution of precipitates, thereby increasing the mechanical strength and fatigue resistance of metal materials. 4. Improve processing performance. The hardness and strength of the quenched metal material are very high, but the processing performance is poor. Insulation can improve this problem and improve the processing performance of the material. Therefore, a special insulation box is needed to keep the quenched steel ball warm.
