Walking beam heating furnace overview

The walking beam heating furnace is a continuous heating furnace that moves the blank step by step by the upward, forward, downward, and backward movements of the furnace bottom or the water-cooled metal beam.

The walking beam heating furnace is also a continuous heating furnace. It relies on a special stepping device to move according to a certain trajectory to make the steel material in the furnace advance step by step, so it is called a walking beam heating furnace.

The walking beam heating furnace can heat the blank on both sides. Compared with the push-steel furnace, its advantages are: flexible material transportation, all the charge can be discharged out of the furnace if necessary; billets are placed at intervals on the furnace bottom or beam, which can be heated evenly faster. Arching and sticking failures of push-steel furnaces are completely eliminated, so furnace length is not limited by these factors.

Walking beam heating furnace features

1. The steel material moves in the furnace by the up and down reciprocating motion of the walking beam, and there is a certain interval between the steel materials. The steel material can be heated on all sides, with high thermal efficiency, short heating time, less iron oxide scale, less possibility of decarburization, and no sticking to steel. There will be no scratches on the surface of the steel material, which is conducive to eliminating black marks and improving the heating quality.

2. Low energy consumption, flexible and convenient operation. Compared with the push-steel continuous heating furnace, the walking beam heating furnace can save about 10% energy. The steel material can move forward or backward in the furnace. When overhauling and changing steel grades, the stepper mechanism can be used to empty and empty all the billets, which reduces the labor intensity of the empty furnace and reduces the steel material in the furnace. oxidation. The charging amount of the furnace can also be controlled according to the size of the rolling output, and the heating time in the furnace remains unchanged.

3. Strong adaptability. The walking beam heating furnace is suitable for heating various steel materials such as ingots, billets, slabs, round billets, etc. The requirements on the length and thickness of the steel materials are not strict. In short, although the structure of the walking beam heating furnace is relatively complex, the investment is large, and the equipment maintenance is more difficult, but because of the above characteristics, it is widely used by manufacturers.

Walking beam heating furnace prospects

At present, one of the most significant features of the development of the walking beam heating furnace is the development of large-scale in order to adapt to the improvement of the hourly output of the rolling mill.

In addition to high output and low consumption, the modern walking beam heating furnace requires strong adaptability and multiple functions, which is another major feature of the current development of the walking furnace. That is to say, as a thermal equipment serving the rolling mill, it can not only adapt to the heating requirements of various billets, such as thick slabs, thin slabs, hot billets, cold billets, and mixed hot and cold billets, but also according to their Different heating temperature adopts different heating methods, and should also adapt to the rolling rhythm and the requirements to be rolled. That is to say, it also has the ability to adapt to continuous tapping and intermittent tapping, and has the ability to match the continuous casting machine. In addition, it can also meet the heating requirements of some special steel grades, such as the requirements for decarburization, temperature difference, and oxidation burning loss.
