A rotary heat type furnace is a cylindrical thermal processing device that rotates around its axis to facilitate the movement and treatment of materials within its heated chamber. These furnaces are typically constructed from a single sheet of steel, forming a cylinder with diameters ranging from 0.9 to 1.8 meters and lengths from 9.1 to 18.3 meters. The furnace is supported by multiple pairs of supporting wheels and is inclined at an angle of 3% to 6%, allowing materials to move from the higher end to the lower end as the cylinder rotates.
Construction and Operation: The rotary furnace consists of a steel cylinder lined with refractory materials to withstand high temperatures. This lining not only protects the steel shell from heat damage but also ensures uniform heat distribution across the furnace's radial temperature. The furnace is driven by an electric motor through gears, which control the slow rotation necessary for the movement of materials inside.
Heating Mechanism: Heat is applied to the furnace through various methods, including direct firing of fuel into the tube or via hot gas discharge from the fuel. In some configurations, a gas burner is mounted on a separate frame, and the heat is generated by combustion within the furnace. The flue gas, produced by the combustion process, is discharged from the higher end of the furnace, creating a counterflow with the materials being processed. This counterflow enhances heat transfer efficiency.
Application and Features: Rotary furnaces are versatile and are used in various industries for processes such as calcining, roasting, drying, and melting. They are particularly suitable for aluminum melting, especially for scrap melting. The furnaces can be equipped with multiple heat zones, allowing for precise temperature control and optimal processing conditions. Additionally, modern rotary furnaces often include advanced features such as digital instrumentation, intelligent temperature control, and integrated safety functions, which improve efficiency, safety, and reliability.
Advantages of Tilted Design: In recent years, rotary furnaces have evolved from static designs to tilted ones. This tilting design offers several advantages, including shorter cycle times, increased throughput, and reduced energy consumption. The tilt allows for more efficient movement of materials through the furnace, enhancing the overall performance and efficiency of the heat treatment process.
In summary, a rotary heat type furnace is a sophisticated thermal processing tool designed to handle a variety of materials and processes efficiently and effectively. Its rotating and tilting mechanisms, combined with advanced heating and control technologies, make it a crucial asset in many industrial applications.
