Description

Technical Field

[0001] This utility model relates to the technical field of color-coated aluminum coil production equipment, specifically to a heat insulation and ventilation structure inside a wind-heated oven. Background Technology

[0002] In the production process of color-coated aluminum coils, the surface needs to be pre-treated by degreasing and dust removal before the coating is evenly applied to the surface of the coil using a roller coating process. The coated aluminum coil is then sent into a high-temperature furnace for curing and drying to solidify the coating into a film. During the research and development of the coating process, it is necessary to conduct simulation experiments on the coating baking temperature, often using a hot air oven.

[0003] In existing technologies, the heat insulation and ventilation structure inside air-heated ovens often uses fine perforated steel plates. However, perforated steel plates cannot effectively and quickly transfer heat from the bottom. At the same time, the fine holes cannot generate a large air velocity, which prevents hot air from circulating and transferring quickly. This results in uneven heating of the undried lead coating surface, which does not match the actual conditions of real product production lines and cannot effectively simulate the heating environment of color-coated aluminum foil in air-heated ovens in real production lines.

[0004] Therefore, this utility model proposes an internal heat insulation and ventilation structure for a wind-heated oven to solve the above problems. Utility Model Content
