There are two kinds of flues—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 brazed are special parts such as titanium alloy and non-ferrous metals, heat screen is made of molybdenum and stainless steel and the material of heating component is molybdenum. Temperature is controlled by smart temperature controller and the operation is controlled by FX2N program controller.

Characteristics

1.Vacuum brazing furnaces are divided into single-chambered horizontal furnace, twin-chambered semi-continuous furnace and three-chambered continuous furnace. The equipment is mainly applied in vacuum brazing of stainless steel, titanium alloy, hard alloy, high-temperature alloy. In order to guarantee the quality of brazing, the equipment is heated by zone control and furnace temperature uniformity is ±3℃. The heat screen is made of molybdenum and stainless steel with molybdenum as the heating material. ( Max. usage temperature is 1300℃)

2.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.
