| Message: | 1.Evergrowing Resources Co., Limited is a global manufacture of industry leading construction and mining equipment, forged steel round bar and hot rolled steel round bar, and deformed bar rebar systems. Now we will introduce the company for you:4. Heat treatment refers to a metal thermal processing process in which the material is heated, insulated and cooled in the solid state to obtain the desired structure and properties. In the process from the Stone Age to the Bronze Age and the Iron Age, the role of heat treatment has gradually become known. Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing methods, heat treatment generally does not change the shape of the workpiece and the overall chemical composition, but changes the microstructure of the workpiece or changes the surface of the workpiece. Chemical composition that imparts or improves the performance of the workpiece. It is characterized by improved intrinsic quality of the workpiece, which is generally not visible to the naked eye. In order to make the metal workpiece have the required mechanical properties, physical properties and chemical properties, in addition to the rational selection of materials and various forming processes, heat treatment process is often essential. The heat treatment process generally includes three processes of heating, heat preservation and cooling, and sometimes only two processes of heating and cooling. These processes are connected to each other and cannot be interrupted. Heating is one of the important processes of heat treatment. There are many heating methods for metal heat treatment. The first use of charcoal and coal as a heat source, the application of liquid and gaseous fuels., included theGood brand, high quality.x382c34an
