Description
Technical Field
[0001] This utility model belongs to the technical field of resistance wire processing, specifically relating to an S-shaped resistance wire processing device. Background Technology
[0002] An electric resistance furnace is a heating furnace that uses an electric current passing through a resistive material to heat an electric heating element or heating medium inside the furnace, converting electrical energy into heat energy. This allows for direct or indirect heating of workpieces within the furnace. Due to its simple structure, uniform and easily controllable temperature distribution, and the absence of smoke, dust, and noise, it is widely used in industry. An industrial electric resistance furnace generally consists of a heating element + insulator, insulation layer, metal shell, and temperature control system. There are many types of materials available for the heating element, including metallic and non-metallic heating elements. Metallic heating elements are diverse, such as iron-chromium-aluminum, nickel-chromium, platinum, molybdenum, and tungsten. Non-metallic heating elements include silicon carbide and molybdenum silicide. However, non-metallic materials lack ductility and cannot be deformed, leading to gradual deterioration and increased resistance during use. From the perspectives of lifespan, stability, and processability, metallic resistance wire is the best choice for ceramic fiber heaters.
[0003] However, uneven pitch of the resistance wire coils leads to significant differences in thermal efficiency. Too close a pitch can cause a short circuit, while too far a pitch results in low heat capacity in that area. Different coils are not on the same horizontal plane, and the depth of the resistance wire embedded in the ceramic fiber varies, causing uneven heat radiation within the furnace and affecting temperature uniformity. Even with specialized tooling and fixtures, this cannot be completely avoided. The coils are typically partially or fully embedded in the ceramic fiber, and this uneven heating under long-term high temperatures poses a risk of short circuits or the coils falling off. Uneven spacing between the two coils also affects the uniformity of temperature distribution within the resistance furnace. All of these factors contribute to uneven temperature distribution within the furnace, resulting in uneven heating of the workpieces and inevitably impacting the defect rate. Furthermore, it shortens the lifespan of the resistance wire, increasing replacement costs for customers. Utility Model Content
