There are many types of forging heating furnaces. According to different power sources, forging heating furnaces can be divided into two categories: flame heating furnaces and electric heating furnaces. Flame heating furnaces are divided into oil furnaces, gas furnaces and coal-fired furnaces according to the different fuels used, while gas furnaces include natural gas forging furnaces and gas heating furnaces; according to the structure of the heating chamber, they are divided into chamber furnaces (single chamber furnaces). double-chamber furnace) semi-continuous and continuous furnace; according to the furnace bottom structure and mechanization form.Application Of Partial Pressure In Vacuum Heat Treatment it is divided into trolley furnace and rotary hearth furnace (also known as ring furnace). Different furnace structures are selected for different production conditions. Single-piece small batch production requires greater flexibility. Chamber furnaces should be selected as much as possible. Large and medium-sized forgings should be trolley furnaces, and small and medium-sized forgings should be produced in large batches. Rotary hearth furnace. The choice of furnace type must also be considered comprehensively from the type of fuel, the quality and size of the heating billet, economic conditions and labor conditions.Application Of Partial Pressure In Vacuum Heat Treatment
