Description
Technical field
The utility model belongs to metallurgy industry Fluid Transmission and Control technical field, specifically provides a kind of bar on-line resistance rust spray equipment.The utility model had both been applicable to newly-designed project, was also applicable to the transformation of old project, had wide marketing prospect.
Background technology
After bar finish rolling, because surface temperature is high, the O in the Fe on its surface and air
2reaction generates iron scale.According to relevant technical data, the iron scale on rod product surface can be divided into three levels in theory, and outermost one deck is Fe
2o
3, be bronzing, generally account for the 1%-2% of whole iron scale thickness, the second layer is Fe
2o
3(often Fe is claimed with the mixture of FeO
3o
4), for black-and-blue, account for 18% of whole thickness, the internal layer that the inside is connected with metal body is FeO, is black, accounts for 80% of whole iron scale thickness.Fe in outside is two-layer
2o
3have antioxygen erosion ability, because it is the oxide of high price iron, not easily losing Fe ion, therefore not easily by the oxygen in the external world, salt and electrolyte corrosion, have anti-oxidant and resistance to corrosion, is bar " protective layer ".But current production line of bar mostly have employed Heat Treatment technology, finish rolling outlet is furnished with Water cooling, and bar has low temperature, the anaerobic environment of about about 2-5s when wearing water, cause Fe in Surface of Rod Bar iron scale
2o
3generate insufficient, " protective layer " thickness low LCL compactness is not enough, and iron scale easily comes off and causes the corrosion of iron simple substance.
In reality, due to bar long-term to deposit with transit link be all outdoor, especially when suffering the severe environmental conditions such as humidity or rainwater, bar from " protective layer " lack or breakage gradually get rusty, and day by day to spread.Red or yellow iron rust is generated after the corrosion of iron simple substance.Bar corrosion not only affects its surface quality greatly, and affects its mechanical property to a certain extent.
The bar on-line resistance rust spray equipment that the utility model provides, after being positioned at multi-length shear before upper cold bed, on each passage of bar, correct position arranges six groups of ring spargers, uniform three nozzles on each ring sparger, ensure that this passage bar is when by ring sparger, resistance rust liquid can be ejected into Surface of Rod Bar with adjustable speed and pressure by nozzle under the effect of electric reciprocating pump, impel Surface of Rod Bar to generate fine and close antirust coat that one deck is rich in ferric ion, improve Surface of Rod Bar quality and corrosion resistance, extend the transport in the same environment of bar and resting period.
The utility model adopts the mode of low discharge high-speed sprinkling to compare, and mode that bar wears resistance rust liquid has a clear superiority in.Finishing mill outlet bar is core temperature about 550 DEG C, surface temperature about 300 DEG C after Water cooling, be cooled water and air film of Surface of Rod Bar surrounds, after penetrating resistance rust liquid, moisture in resistance rust liquid is also vaporized generation air film, and the air film around such bar hinders the become rusty active ingredient of liquid and fully contacting and reaction of Surface of Rod Bar to a certain extent.Simultaneously bar institute to wear the become rusty seal request of liquid device of resistance higher, pressure is wayward.The utility model is considered to allow resistance rust liquid high-speed sprinkling to Surface of Rod Bar according to certain angle under pressure, can break up air film that is intrinsic around bar or rear life, ensures that often spray point place's resistance rust liquid all can fully contact with Surface of Rod Bar and react.Simultaneity factor pressure is easy to adjust.Resistance rust effect of the present utility model will improve greatly.
