Sintering Plant Wisco workshop sintering ignition furnace overhaul in 2016, during overhaul, Wuhan Iron and Steel Plant research institute and sintering plant
Cooperation, is investigated to the damage of furnace lining situation of ignition furnace.Crossbeam avalanche is found by investigating, the situation of fracture is more serious,
And in other sintering mill (plant) ignition furnaces it has also been found that similar phenomenon.Sintering plant if it find that crossbeam is damaged, is gone here and there in the inspection of daily point
Fire burn with anger phenomenon it is serious when, it is necessary to repairing or in repair;Therefore the quality and performance of sintering ignition furnace crossbeam how are improved,
It is the key for improving its service life.
The span of crossbeam is big in existing ignition furnace, and only using only steel fiber castable, then its rupture strength is less than normal, makes
Easily occur being broken and peeling off in.In the production of reality, crossbeam is that cast in situs forms in ignition furnace, and anchor has been hung on top
Gu brick, on the steel construction on crossbeam top, some is shared stress on top by steel construction, but because crossbeam itself has one
Determine weight, and in sintering furnace thermal current impulsive force it is also very big, therefore, after a certain period of use time, anchored brick is most of for crossbeam
It is broken.
