Description
Technical field
The utility model relates to technical field of metallurgical machinery, more particularly, to one kind from pendulum-type covering/uncovering device.
Background technique
It is energy-saving, to increase economic efficiency be the most important operations objective of steel mill.Ladle is both between converter and continuous casting
Molten steel transport cool-bag and external refining melted steel container, from tapping to continuous casting during, liquid steel temperature reduces master
To have to the heat dissipation capacity of atmosphere and through involucrum to the heat dissipation capacity of environment with cylinder-packing refractory material amount of stored heat, exposed liquid level or slag blanket
It closes.The amount of stored heat of cylinder-packing refractory material influences maximum to molten steel temperature drop, and production process emphasis will solve to be that cylinder-packing refractory material stores
Heat and ladle mouth heat dissipation problem.
New ladle prevents liquid steel temperature before use, heated (i.e. accumulation of heat) to cylinder-packing refractory material using roasting mode
Decline too fast；It after Sheng Gang, further conducts heat between cylinder-packing refractory material and molten steel, the amount of stored heat of cylinder-packing refractory material further increases
Add, declines liquid steel temperature；After casting, the heat of cylinder-packing refractory material is most of in addition to a part is radiated outward by involucrum
Heat is lost by heat radiation and convective heat transfer from packet mouth, and (pouring steel terminates, 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 cost, 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 converter, refining, continuous casting, the entire STEELMAKING PRODUCTION ring such as slag, hot repair that falls
Section.Simple, the reliability for realizing uncovery movement are the key that whether determining project success.
