What will be the consequences if it exceeds 25mm? If the curvature of an individual furnace column is not up to standard, how should it be adjusted? If the curvature of an individual furnace column is too large, can it be corrected or reinforced?
The specifications for furnace column curvature are usually based on the manufacturer’s guidelines and industry standards. If the curvature of the furnace column exceeds the specified value, it may cause the electrodes inside the furnace to shift out of position, preventing the charge from being heated properly and affecting both the smelting efficiency and the lifespan of the equipment. For cases where the curvature of individual furnace columns does not meet the requirements, fine adjustments can be made by adjusting the furnace plates and electrode angles. If the curvature of the furnace column is too large, measures such as using reinforcing materials or replacing the furnace column can be considered for repair. It should be noted, however, that a furnace column curvature of over 25 mm is considered a relatively serious condition that requires careful handling. -
What is an appropriate specification for the curvature of the furnace column? For coke ovens that were 4.3 meters in length in the past, it was said that the thickness should not exceed 25 mm. But what about now, with longer furnace columns – is the thickness still 25 mm? For example, if you’re given a 10-meter-long rebar bar, it’s easy to bend it ； Give you a 10-centimeter steel bar, and it will be very difficult to bend it.
The specifications for furnace column curvature need to take into account various factors, including the furnace’s size, materials, and manufacturing process. Generally, a furnace column curvature of 10 to 25 mm is considered appropriate; however, it needs to be evaluated and determined based on specific circumstances. For furnace columns of different lengths, the curvature limits also vary. Generally speaking, the longer the furnace column, the less restrictive its curvature is, ensuring precision in the distance and position between the electrodes and the charge inside the furnace. In general, the specification for the curvature of the furnace column needs to be determined scientifically and reasonably based on actual conditions, in order to ensure the proper operation and safety of the equipment. .
