Common flame heating equipment for forging is mainly divided into intermittent charging and continuous charging according to the charging method.

The editor will be divided into three articles to classify and explain in detail different types of flame heating equipment, and their application scope and characteristics. If there is something wrong, please leave a message or contact us.

Intermittent charging flame heating equipment mainly includes hand forging furnaces, chamber furnaces, open-gap furnaces, through-type furnaces, reciprocating grate, car bottom furnaces, open flame non-oxidation heating furnaces, etc.

1. Hand forge

The hand forging furnace has simple structure, difficult to control heating quality and temperature, and high labor intensity. It is mostly used for heating various small and medium-sized forgings in single and small batches, and is generally used for manual forging or repair forging. Hand forging furnaces can be divided into open furnace, closed furnace, single burner, double burner, movable and fixed.

2. Chamber furnace

The chamber furnace has a simple structure and a heating furnace with an open and closed door. It is mostly used for heating single or small batches of various medium and small free forgings. It is a more traditional heating method. Among them, the double-door chamber furnace has a compact structure, energy saving, and large production capacity, which can avoid overheating and oxidation of the forging billet and effectively use energy. Suitable for multiple heating and heating of alloy steel. The regenerative furnace has high combustion efficiency, can effectively reduce energy consumption, and has a fast heating speed; it is suitable for pre-forging heating of medium and small billets and ingots. The workpiece is generally not more than 3 tons. It can be used with medium and small free forging hammers or die forging hammers. Supporting the use of.

3. Open-gap furnace

The open-gap furnace has a simple structure, no furnace door, and a gap of 100mm~200mm in the furnace mouth, also called a gap-type furnace. High heating efficiency and convenient feeding and discharging. It is mostly used for mass production of small and medium-sized die forging, tire die forging, manual forging, and partial heating of rod ends or blanks, and can be used with friction presses. Double-chamber open-gap furnace with large production capacity. Now there are more innovations and patents for open-gap furnaces, such as connected circulating shuttle open-gap furnaces and rotary open-gap furnaces.

4. Through furnace

Through-type furnace, with preheating section in the furnace, some are equipped with preheating chamber, heating chamber and quenching chamber and other multi-stage two-stage furnaces, which can be used for heating or heat treatment of various medium and small free forgings, die forgings and long rod forgings .

The regenerative through furnace has high combustion efficiency and fast heating speed, which can effectively reduce energy consumption. It is suitable for continuous heating of carbon steel, low alloy steel, stainless steel and other billets or bars, and can be used with die forging hammers.
