Abstract
The utility model discloses a slag accumulation prevention structure for a fan-shaped section of a slab continuous casting machine. The slag accumulation prevention structure comprises fan-shaped section upper frames. The fan-shaped section upper frames which are uniformly distributed at intervals are positioned above a slab, blowing tubes with uniformly distributed nozzles are respectively horizontally disposed among the adjacent fan-shaped section upper frames, and the nozzles blowing air to the slab are fan-shaped. By the aid of the slag accumulation prevention structure, impurities, including scale, residual protecting slag and the like, accumulated during blockage of a spraying tube or running stop of a roll can be timely blown out of a casting slab by the aid of the compressed air before being squeezed into hard blocks, cleaning is carried out, and accidents of scratching the casting slab or unscheduled machine halt and the like are avoided.
Description
Technical field
The utility model relates to a kind of segments of slab section preventing deposit structure.
Background technology
Slab caster, molten steel through in bag form slab through the crystallizer cooling after getting into crystallizer, get into a section of leading and fan-shaped section through a section of leading, the cooling of fan-shaped section shower water after the formation final products.Strand gets in the fan-shaped section process of billet withdrawal, and the high temperature casting billet surface can form one deck oxide skin at casting billet surface after running into shower water, also has some covering slags to remain in casting billet surface, and spray is cooled to steam to be mixed, and act as strand cooling and iron scale cleaning.If fan-shaped section has shower to stop up or roller turn is dumb, be squeezed into lump and then cause strand to scratch after can causing iron scale to pile up.
Summary of the invention
The purpose of the utility model is to provide a kind of segments of slab section preventing deposit structure, can in time purge to remove the lip-deep foreign material of slab, avoids strand scuffing accident.
The purpose of the utility model is to realize like this; A kind of segments of slab section preventing deposit structure; Comprise and be positioned at the slab fan-shaped section upper frame that is uniformly distributed with spaced above; Between adjacent fan-shaped section upper frame, be horizontally disposed with the scavenging conduit that is evenly equipped with nozzle respectively, the nozzle of blowing towards slab all is fan-shaped.
The utility model can shower stop up or during the roller stall with heap get iron scale, residual foreign material such as covering slag utilize compressed air in time to blow out strand when not being squeezed into lump, clear up, and avoid strand to scratch or accident such as non-programmed halt.
Description of drawings
To combine accompanying drawing that the utility model is done further detailed explanation below.
Fig. 1 is the main TV structure sketch map of the utility model.
The specific embodiment
A kind of segments of slab section preventing deposit structure; As shown in Figure 1; Comprise being positioned at the slab fan-shaped section upper frame 2 that is uniformly distributed with spaced above, between adjacent fan-shaped section upper frame 2, be horizontally disposed with the scavenging conduit 1 that is evenly equipped with nozzle respectively, the nozzle of blowing towards slab all is fan-shaped.The utility model can shower stop up or during the roller stall with heap get iron scale, residual foreign material such as covering slag utilize compressed air in time to blow out strand when not being squeezed into lump, clear up, and avoid strand to scratch or accident such as non-programmed halt.
Claims (1)
1. segments of slab section preventing deposit structure; Comprise and be positioned at the slab fan-shaped section upper frame that is uniformly distributed with spaced above; It is characterized in that: between adjacent fan-shaped section upper frame, be horizontally disposed with the scavenging conduit that is evenly equipped with nozzle respectively, the nozzle of blowing towards slab all is fan-shaped.
