There are many kinds of forging furnace. According to different power
sources, forging furnace can be divided into flame furnace and electric furnace.
According to the different fuels used, the flame furnace can be divided into oil
furnace, gas furnace and coal furnace, while the gas furnace can be divided into
natural gas forging furnace and gas heating furnace. According to the different
structure of heating chamber, it can be divided into chamber furnace (single
chamber furnace, double chamber furnace) semi-continuous furnace and continuous
furnace. According to the furnace bottom structure and mechanization form is
divided into trolley furnace and bottom furnace (also known as ring furnace).
Different furnace structure should be selected under different production
conditions, and chamber furnace should be selected as far as possible for small
batch production of single piece, trolley furnace should be used for large and
medium-sized forgings, and rotary bottom furnace should be used for small and
medium-sized forgings. The selection of furnace type must also consider the fuel
type, the quality and size of the heated billet, economic and labor conditions,
etc.
Reverberatory furnace
The reflector is a flame heating furnace using bituminous coal as fuel. The
reflector is mainly composed of combustor, heating chamber, air supply device,
heat exchanger and flue, chimney, etc.
Heavy oil and gas furnaces
The structure of gas and natural gas is basically the same. There is no
special combustion chamber, but the heavy oil or gaseous fuel and air are
injected directly into the heating chamber by the nozzle or burner (burner,
burner). But the burner is different, heavy oil burner, natural gas burner and
gas burner are not the same.
Gas forging furnace
Forging furnace is on the basis of the original coal furnace improved
equipped with gas from the gas generator for combustion heating furnace type,
generally choose according to forging furnace size configuration suitable
producer gas generator, the size of a small 1.3 configurations of ordinary small
producer gas generator, also have a large forging enterprise, with a gas
generator with many sets of forging furnace. Compared with the combustion
chamber of the original reverberatory furnace, the gas produced by the gas
generator is directly injected by the gas burner into the greenhouse with higher
efficiency than that of the reverberatory furnace and basically no emission
pollution.
Resistance furnace
It USES resistance generators to convert electrical energy into heat energy to heat the metal. It is mainly used for heating superalloys and non-ferrous metals and their alloys with strict temperature requirements.
