Description

A kind of milling train gas curtain descaling device
Technical field
The utility model belongs to hot-rolled steel section technical field, and particularly, the utility model relates to a kind of milling train gas curtain descaling device.
Background technology
At present, along with the development of domestic steel building industry, shaped steel is one of important former material progressively becoming this field steel.But due to the complexity in shaped steel cross section, finished surface is second-rate, and especially after shot-peening or sandblasting, its surface often exists pit or pockmark problem in various degree, just can spray paint after having to pass through necessary repairing, otherwise the aesthetic property of integrated steel-structure can be had a strong impact on.For improving shaped steel surface quality, common way is de-scaling water pressure, the water yield of a raising high pressure water descaling device or increases intermediate water descaling device, but this class methods equipment investment is huge, and significantly can increase de-scaling water consumption, be the larger load of production line water treatment increase.
Utility model content
The purpose of this utility model is, provide a kind of milling train gas curtain descaling device, this device has the features such as structure is simple, equipment investment is little, auxiliary equipment is few, stable, is particularly suitable for the production line that place, workshop is little, water treatment capacity has reached the upper limit.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of milling train gas curtain descaling device, described device comprises several high-pressure blast pipelines 1, described arbitrary high-pressure blast pipeline 1 connects several nozzles 2 for purging rolled piece 3 surface.
Preferably, the quantity of described high-pressure blast pipeline 1 is eight, is evenly arranged at before and after roll 4.Those skilled in the art according to actual needs, can also adopt the high-pressure blast pipeline of other quantity, such as ten etc.; And the set-up mode of high-pressure blast pipeline also can adopt other forms, such as before roll, arrange four, after roll, arrange six, etc.
Preferably, the quantity of described nozzle 2 is two.Those skilled in the art according to actual needs, can also adopt the nozzle of other quantity, such as four etc.
Preferably, described nozzle 2 is circular, oval or square.Apparently, designs of nozzles can also according to actual needs, be other shapes by those skilled in the art, and such as trapezoidal etc., in addition, those skilled in the art can also be embedded on mesh sheet or opening and cover nethike embrane etc. in the opening of nozzle.
Preferably, the angle θ between the axis of described nozzle 2 and high-pressure blast pipeline 1 place plane is 30 ~ 60 °.
Preferably, the shape of described high-pressure blast pipeline 1 is Π type.High-pressure blast pipeline according to actual needs, can also be designed to other shapes, such as annular etc. by those skilled in the art.
Preferably, on any two adjacent high-pressure blast pipelines 1 described, the direction of set nozzle 2 is relative or contrary.The air-flow that nozzle is sprayed forms an angle of intersecting.Forming air mass by intersecting to purge on shaped steel surface, improving the Scavenging activity of material shaped steel surface residual cooling water, secondary iron scale, tiny scraping etc. easily being reduced to shaped steel surface quality, thus effectively improving finished surface quality.
Purging wind pressure in the utility model can be 0.5 ~ 2.0MPa.
The utility model mesohigh air pipe line is control separately, can by the opening and closing combination of different high-pressure blast pipeline (such as, first high-pressure blast pipeline is closed, second, the 3rd, the 4th unlatching, simultaneously, 5th, the 6th unlatching, the 7th closedown, the 8th unlatching) improve the Scavenging activity that rolled piece surface residual cooling water, secondary iron scale, tiny scraping etc. easily reduce the material of shaped steel surface quality.
The beneficial effects of the utility model are:
1. the utility model structure is simple, and the difficulty of processing of device own is low, does not need the equipment such as newly-increased high-pressure hydraulic pump, motor simultaneously, has the advantage of small investment.
2. the utility model is frame for movement, does not need relevant auxiliary equipment, has stable, changes advantage easily.
3. the utility model forms air mass by intersecting to purge on shaped steel surface, improves the Scavenging activity of material shaped steel surface residual cooling water, secondary iron scale, tiny scraping etc. easily being reduced to shaped steel surface quality, thus effectively improves finished surface quality.
