UBE Box-Type Multi-Purpose Furnace

UBE Box-Type Multi-Purpose Furnace Product Introduction—Equipment Overview: The UBE series box-type multi-purpose furnace is one of our company’s flagship products. This equipment is mature and reliable, features low operating costs, and is easy to maintain. It boasts excellent product stability and consistency, making it a box-type gas carburizing furnace with a high market share in China. Main Applications: Carburizing/Carbonitriding/Quenching, Normalizing, Annealing under protective atmospheres; Secondary Heating Quenching. Key Features: ◆ The muffle’s round furnace chamber design eliminates dead corners, greatly improving the circulation of the furnace atmosphere and enhancing temperature and atmosphere uniformity. At the same time, under the same effective working area, the furnace body’s heat dissipation surface area is reduced compared to a square furnace chamber, resulting in significant energy savings. ◆ The furnace chamber is constructed using high-quality, imported anti-carburizing bricks, and a fully fiber-based structure is available as an option. ◆ A large-capacity oil tank equipped with a specially designed flow guide system and a variable-frequency speed-controlled stirring device ensures automatic control of oil temperature, delivering consistent quenching results for various workpieces. ◆ The radiant tubes operate on low-voltage power supply, offering high safety, long service life, and easy replacement. ◆ The equipment is fitted with a comprehensive self-diagnosis and safety interlock control system. ◆ A thyristor-based power controller provides continuous control over the heating process, automatically adjusting the heating power according to furnace temperature requirements for precise temperature control. ◆ The equipment is controlled by a programmable logic controller (PLC), featuring simple operation, convenient maintenance, and a high degree of automation. ◆ Temperature and carbon potential controllers, oxygen probes, PLCs, recorders, pneumatic components, low-voltage electrical equipment, and various instruments are all sourced from world-renowned brands, ensuring overall equipment performance that is stable and reliable. ◆ A high-precision atmosphere control system enables the establishment of a stable carbon potential within the furnace.
