The continuous ring heating furnace has its unique core technology in comparison with other heating furnaces, and its brief descriptions are as follows: 1. Most of the automotive high-strength steel blank is sheet. The sheet should be heated up to the specified temperature and then keep the temperature in order to be fully austenitized. Therefore, the temperature distribution in the heating furnace is required to be homogeneous; 2. For the steel sheet without protective coating from oxidation, its oxidation and decarburization is very serious at elevated temperatures.
14b. The hot forming part is shown in Fig. 15. 2 Indirect Hot Forming process 41 Fig. 11 Sketch map of hot forming process with indirect method of hot forming Fig. 12 Parts produced by indirect hot forming technique Fig. 13 Reinforced beam with direct method of hot forming forming process, microstructure and mechanical properties of some parts should be tested. The results of tensile test for the samples cut on the strengthened beam are shown in Fig. 16. The stress–strain curve shows that the yield strength of the hot forming parts is more than 1,000 MPa, and tensile strength is above 1,600 MPa.
In order to prevent sheet from oxidation and decarburization at elevated temperature, this continuous ring heating furnace is equipped with anti-oxidation gas-filled device of controlled flow and pressure. 4 Brief Introduction of Key Equipments and Production Lines in Hot Forming 29 Fig. 2 High-Temperature Resistant Robot Arm and Automatic Transfer Device for Loading and Unloading During the forming process, the blank is heated to be austenitized in a heating furnace at a temperature ranging from 800 to 1,000 °C.
