Heat is lost by heat radiation and convection current heat transfer from packet mouth, and (pours steel to terminate, open steel as the extension heat loss of time is bigger
650-700 DEG C will be down to by 1300 DEG C by wrapping vacant 1 hour cylinder-packing temperature).In order to reduce cylinder-packing accumulation of heat caused by liquid steel temperature
It influences, cylinder-packing temperature is generally improved by online ladle baking, but this mode not only increases energy consumption and operation link, in fact
Border effect is also not satisfactory.
Steel ladle full stroke covering technology is to prevent the most effectual way of cylinder-packing temperature loss, can reduce ladle baking coal gas and disappear
Consumption saves LF heating costs, cancels ladle heat insulation agent consumption, stablizes liquid steel temperature gradient, improving ladle and serve as a contrast resistance to material service life etc., has
Conducive to stablizing each process technology controlling and process, realizing molten steel cold operation, reduction energy consumption, raising product quality, good warp is achieved
Benefit of helping and social benefit.
For be greatly decreased in steel (iron) packet circular flow temperature loss, reduce production cost, iron and steel enterprise favors very much
In implementation steel ladle full stroke covering technology.The technology is related to the entire STEELMAKING PRODUCTION ring such as converter, refining, continuous casting, deslagging, hot repair
Section.Realize that simple, the reliability of uncovery action are the key that whether determining project success.
