At present, domestic metallurgical enterprises have basically realized mechanized production, and walking beam heating furnace is the most widely used mechanical equipment. Next, Guangzhou Youzao will take you to understand what is a walking beam heating furnace and what are the characteristics of a walking beam heating furnace?
What is a walking beam furnace
The walking 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 heating furnace is also a continuous heating furnace. It relies on a special stepping mechanism to move according to a certain trajectory (usually a rectangular trajectory) to make the steel material in the furnace advance step by step, so it is called Walking furnace.
What are the characteristics of walking beam heating furnace
(1) The steel material moves in the furnace by the reciprocating motion of the walking beam up and down. 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, and possibility of decarburization. Small, no sticking to steel, no scratches on the surface of steel, which is beneficial to eliminate black marks and improve heating quality.
(2) Low energy consumption, flexible and convenient operation. Compared with the push-steel continuous heating furnace, the walking furnace can save about 10% energy. The steel material can move forward or backward in the furnace. When overhauling and changing steel types, 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 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. Guangzhou Youzao believes that although the structure of the walking furnace is relatively complex, the investment is large, and the equipment maintenance is more difficult, but because it has the above characteristics, it is mostly used by manufacturers.
Today's metallurgical enterprises use walking beam furnaces, which can continuously heat metal billets. The biggest feature of walking beam heating furnace is low energy consumption and cost saving.
