Connected heat treatment furnaces are furnaces used in industry for the heat treatment of workpieces. These furnaces are often connected to other equipment or facilities, such as manufacturing machines or cleaning equipment, to enable continuous production. Heat treatment of workpieces is an important process in the metal industry that can improve the properties of metals. For example, heat treating steel parts can increase their hardness, strength and wear resistance. The process can also be used to reduce internal stresses or improve the formability of metal parts. Attached heat treatment furnaces can come in various shapes and sizes. They can be continuous furnaces, carousel furnaces, or continuous conveyor furnaces. The selection of the right type of furnace depends on the specific requirements of the production process. The combination of heat treatment furnaces with other equipment and systems enables high efficiency and productivity in production. For example, workpieces can pass directly from the production machine to the heat treatment process and then be further processed in the cleaning plant. The entire production process can thus take place without any loss of time or interruptions. Overall, connected heat treatment furnaces are an important part of industrial production, especially in the metal industry. They enable precise and controlled heat treatment of workpieces and seamless integration into the manufacturing process.
