There are two kinds of horizontal annealing furnace-graphite flue and metal flue. Graphite flue is often chosen as the material with graphite rod as the heating material and heat screen is generally made of carbon felt and pottery felt. If parts which are to be processed are special materials such as titanium alloy and soft magnetic alloy, metal flue is chosen as the material with molybdenum as the heating material and heat screen is made of molybdenum and stainless steel. Electrical control system features with high automation with reliability and stability. Temperature is controlled by smart temperature controller and the operation is controlled by program controller.
1.Under the temperature of 800℃, circulative fan produces the rapid and uniform heating in low-temperature zone.
2.The structure of heating chamber is arranged scientifically, therefore it is heated uniformly and thermal losses are getting decreased with energy conservation.
3.The new-type pottery felt which is used as the heat preservation material could endure high temperature and it increases the service life of the heat screen.
4.The system is controlled by PLC and touch screen shows the working condition. It is easy to choose the manual operation or the automatic operation. The alarm system responds automatically if the numerical value of temperature, water pressure or air pressure is found greater than setting value.
