是指材料在固态下，通过加热 、 保温 和 冷却 的手段，以获得预期组织和性能的一种金属热加工工艺。 Heat treatment refers to a metal thermal processing process in which the material is in a solid state by heating , holding, and cooling to obtain the desired structure and properties.
工艺的基本知识就是将金属材质的锻件放在一定的介质中加热到适宜的温度，并在此温度中保持一定时间后，又运用不同速度冷却的一种工艺。 The basic knowledge of the heat treatment process of the rigging factory is a process in which the metal forgings are heated to a suitable temperature in a certain medium and maintained at this temperature for a certain time, and then cooled at different speeds.
The purpose of the heat treatment process in the rigging factory is to change the internal structure of the forging to improve the properties of the steel. Through proper heat treatment, the mechanical properties of the forging rigging can be significantly improved and its service life can be extended. Appropriate heat treatment process can eliminate various defects caused by the rigging process, refine grains, eliminate segregation, reduce internal stress, and make the structure and performance of the rigging more uniform. Metal heat treatment is one of the important processes in the production of rigging plants.
The heat treatment of the rigging plant generally does not change the shape of the forging and the overall chemical composition, but improves the performance of the rigging by changing the microstructure inside the rigging or changing the chemical composition on the surface of the rigging. Its characteristic is to improve the inherent quality of the rigging, which is generally not visible to the naked eye. In order to make the rigging have the required mechanical properties, physical properties and chemical properties, in addition to the reasonable selection of materials and various forming processes, heat treatment processes are often essential. Metal is the most widely used material in the machinery industry. The microstructure of steel is complex and can be controlled by heat treatment.
Through the application of heat treatment, the rigging factory changes the mechanical, physical and chemical properties of the forging products to obtain different performance properties. The heat treatment process can not only strengthen the rigging, but also fully tap the material performance potential, reduce the structural weight, save materials and energy, and improve the product quality and greatly extend the service life of the forging rigging.
