Description
Technical field
The utility model relates to stainless steel production technical field, particularly relates to a kind of hot rolling line section cooling demister.
Background technology
Band steel on stainless steel hot-rolling production line, after mm finishing mill unit hot rolling out, needs to deliver to fast in coiling machine and carries out batching rolling, is with steel to need to remain on suitable temperature when batching, and coiling temperature can influence zone steel inside metallographic and mechanical property.Due to band steel, from mm finishing mill unit hot rolling, out rear temperature is higher, needs to adopt cooling device to reduce the temperature to suitable coiling temperature.Prior art is generally adopt cooling facility for laminar flow to lower the temperature, this cooling facility for laminar flow is provided with many water-cooling-sprayers above the roller-way being with steel to advance, lowered the temperature by shower nozzle spraying cooling water, profit can produce a large amount of water vapours when cooling in this way, cause water smoke in workshop very large, and water vapour also easily enters the parts such as the bearing of roller-way, bearing etc. is got rusty easily damage.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of hot rolling line section cooling demister that can increase cooling effect, drain water smoke in time.
The utility model for the technical scheme reaching above-mentioned technical purpose and adopt is: a kind of hot rolling line section cooling demister, comprise milling train cooling roller bed and be located at the cooling facility for laminar flow on milling train cooling roller bed, described cooling facility for laminar flow is provided with many row's chilling spray water pipes, side below milling train cooling roller bed below wherein said cooling facility for laminar flow is provided with blowning installation, opposite side below milling train cooling roller bed is provided with air extractor, two sides above milling train cooling roller bed below described cooling facility for laminar flow are provided with the air knife that upwards air blowing prevents steam from distributing, the top of described cooling facility for laminar flow is provided with collection device of water vapor, the return duct of described collection device of water vapor communicates with the tank of cooling facility for laminar flow.
Described air knife is that the crossflow fan installed continuously is formed, and described crossflow fan is arranged on a section bar, and described section bar two ends are provided with Rapid fastener, are convenient to integral demounting air knife, is convenient to milling train cooling roller bed and safeguards.
Described blowning installation is drip-proof fan or air blast.
The beneficial effects of the utility model are: adopt said structure, by the air knife arranging steam blowing and air extractor in the milling train cooling roller bed below cooling facility for laminar flow and prevent steam from distributing, a collection device of water vapor is set above cooling facility for laminar flow, form a demister can effectively removed water smoke, prevent water smoke from distributing in workshop, the water vapour of gathering can be taken away in time, the cooling effect of laminar flow apparatus can also be improved.
