Cast Aluminum Heating Ring Details
Cast aluminum heating rings can be divided into die-cast and cast types. In cases with many specifications and sizes, the casting process is generally used. During casting, high-purity aluminum blocks are melted from solid to liquid in a high-temperature furnace, then injected into a mold with heating tubes already installed. After cooling and forming, precision machining is performed. The normal thickness of cast aluminum heating rings is 20mm and 25mm. The 25mm thick heating ring features a concave-convex air groove structure on its inner wall, designed to prevent the internal heating tube from overheating during use. For example, when the temperature is high, air or water cooling can be applied to the inner wall to quickly reach the standard operating temperature. Additionally, heating rings are usually split into two semicircular halves, which are then fixed and installed using bolts. Temperature measurement is mainly used for
