An industrial furnace is a thermal equipment that heats materials or workpieces by using the heat of fuel combustion or electrical energy conversion in industrial production. Broadly speaking, a boiler is also an industrial furnace, but it is customary not to include it in the scope of industrial furnaces. Industrial furnaces are divided into two categories according to the heating method: one is a flame furnace (or fuel furnace), which uses the combustion heat of solid, liquid or gas fuel in the furnace to heat the workpiece; the second is an electric furnace, which is used in the furnace. Convert electrical energy into heat for heating.Vacuum sintering furnace Industrial furnaces are divided into two categories according to the thermal system: one is the intermittent furnace, also known as the periodic furnace, which is characterized by the fact that the furnace is not divided into temperature zones, and the furnace is produced in one or two shifts. The temperature varies, such as various chamber furnaces, trolley furnaces, pit furnaces, bell furnaces, etc.; the second is a continuous furnace, which is characterized by the division of temperature sections in the furnace, which is generally composed of preheating, heating (high temperature) ), soaking (heat preservation) three sections, the furnace is three-shift continuous production, and the temperature in each section can be considered unchanged during the heating process of industrial furnaces, such as two-stage or three-stage continuous heating furnaces , pusher type heating furnace and heat treatment furnace, annular furnace, walking furnace, vibrating hearth furnace, cupola and lime kiln, etc.https://www.vacfurnace.com/techn...uum-sintering-furnace-3/
