Description
Technical field
The utility model relates to dedusting technology field more particularly to a kind of dust collection device for continuous casting tundish.
Background technique
Continuous casting is the molding main means of current steel material, complete by conticaster by primary or secondary smelting molten steel
At the transformation for being progressively solidified into required solid shape (slab, square billet, round billet, shaped blank etc.) by liquid.
In the casting process of conticaster hot liquid molten steel by ladle fall into tundish, again by tundish fall into crystallizer into
Row casting, can generate the initial stage that a large amount of fume gases, especially molten steel are fallen into tundish by ladle in this process
Fume amount is huge, while in casting process, and the hot liquid molten steel in ladle and tundish can also generate flue dust.The behaviour of casting position
Workmanship can only work in flue dust, also result in influence to power house environment.
For smelting the conticaster for the steel grade that is detrimental to health, requirement must add dust removal installation in accordance with the law.Due to casting area
Overhead traveling crane, ladle turret, tundish car are arranged vertically in domain, spaces compact；And ladle turret will be turned round, be risen in casting process
Drop, tundish will go up and down, are traversing；Especially to guarantee that ladle and tundish can leave casting position as early as possible under accident conditions；Simultaneously
The handling of casting casting area's equipment (such as crystallizer, tundish spill box) should not be also interfered during non-casting.It is domestic at present logical
It is often that lateral air inlet as big as possible is set between ladle and tundish, is smoked by force gas using high-power blower.But it casts
When hot fume be it is instantaneous generate quickly ascension diffusion upwards, if none sufficiently large fume collection space and be directed to
Side suction inlet is difficult to play dustproof function, can only drain a small amount of flue gas.It continues growing suction air volume effect to be not obvious, Er Qiehui
Cause temperature drop in tundish too fast, influences slab quality.Such dust removal installation dust removing effects are very poor, cannot be to worker's
Health forms effective protection.
