Research on Design Method of Radiation Field Used for Soft-base Coat Infrared Drying

摘要

According to the characteristics and difficulties of the soft-base coat drying, the approach of solving the temperature sensitivity through the furnace type structure design as well as the mechanical and electrical chain design is put forward. The form of the infrared radiation field used for soft-base coat drying is determined. By analyzing the characteristics of the infrared heating element and its reflection equipment, a mathematical model of radiation is proposed, and by using of the results and programs obtained from the model, the scientific design method of infrared radiation field is presented. The problem of requirements for uniform temperature of the soft-base coat is solved by infrared radiation field design and movement of belt. By taking the energy saving reconstruction of an infrared blast furnace as an instance, the effectiveness of the proposed method is verified. The design method not only has guiding significance to the design of soft-base coat infrared drying, but also has reference value to other types of infrared heating design for energy saving.
