Technical field
The invention belongs to hot-rolled reinforced bar technical field, the device of the online corrosion protection processing of a kind of screw thread steel is particularly provided, for the online short-term corrosion protection of screw-thread steel wire rod.
Background technology
Screw-thread steel wire rod refers to the screw-thread steel of producing with high-speed rod-rolling mill, because it becomes coil type delivery, therefore be commonly called as valve snail.In industry, said screw-thread steel refers to bar mill and produces, and the condition of delivery is vertical bar shape, therefore be commonly called as straight spiral shell (being generally called screw-thread steel).Both are referred to as hot rolled ribbed bars above.
Hot rolled ribbed bars is the steel product of building trade consumption maximum, directly use the performance of being with rust reinforcing bar can reduce concrete integral structure, and before using, rust cleaning will increase construction party cost and operation.Present stage, the corrosion protection work of Ribbed Bar only, for screw-thread steel (straight spiral shell), is not also in full swing for the research work of screw-thread steel wire rod corrosion protection.Hot rolled ribbed bars surface corrosion is mainly formed at the cooling procedure after finish to gauge, oxidizing temperature, oxidization time, oxygen supply degree and cooling velocity are the principal elements that affects its Nomenclature Composition and Structure of Complexes, and can the key that improve reinforcing bar anti-corrosion performance be in cooling procedure, improve the Nomenclature Composition and Structure of Complexes of surface scale.
Summary of the invention
The object of the present invention is to provide the device of the online corrosion protection processing of a kind of screw thread steel, solved screw-thread steel wire surface and held corrosion-prone problem, this device can, by screw-thread steel wire rod online through the means of antirust solution, reach antirust object.
The present invention includes nozzle 2, water pipe 3(annular), regurgitate purging air nozzle 4, strainer valve 6, liquid back pipe 7, corrosion protection liquid bath 8, woven hose 9, adjustable pressure pump 10, water pipe inwall 11, water pipe outer wall 12.
Guide groove 1 is that production line is original, fix on the ground by support, the present invention by mechanical connection around guide groove 1, wherein nozzle 2 is fixed on water pipe inwall 11, water pipe 3 is the cavity place between water pipe inwall 11 and outer wall 12(, regurgitating purging air nozzle 4 is fixed on water pipe inwall 11, when use, be connected with original air duct in workshop, strainer valve 6 is installed in the middle of liquid back pipe 7, installation corrosion protection liquid bath 8 below guide groove 1, woven hose 9 is fixed on guide groove 1 below, its end opening immerses below the liquid level of corrosion protection liquid, adjustable pressure pump 10 is fixed on the centre of woven hose 9.
By this device double thread steel wire rod surface spraying liquid, in liquid, contain proprietary medium, thereby form overcoat on surface, reach the object of screw-thread steel wire rod corrosion protection.
The corrosion protection liquid medium relating in the present invention, be that each rises in phosphoric acid, the aluminium hydroxide that contains 50-100 gram, the zinc oxide of 3-5 gram, the nickel oxide of 3-5 gram or chromium oxide, be heated to 250-300 DEG C through heating up, and makes fixing raw material miscible in phosphoric acid, be cooled to after room temperature by the volume ratio of 1:10-20, be diluted with water nonpoisonous and tastelessly, the anti-etching treatment fluid of reinforcing bar in the time limit of not losing efficacy.This medium does not belong to content of the present invention.
During 900 DEG C of left and right, by the guide groove of its operation, install the corrosion protective device the present invention relates to additional in the surface temperature of screw-thread steel wire rod.By spray corrosion protection liquid (previously mentioned medium), form protective layer on the surface of screw-thread steel wire rod, reach the object of corrosion protection.
Another feature of the present invention is after used antirust solution is processed by strainer valve 6, through liquid back pipe 7, can recycle.
Screw-thread steel wire rod is after rolling, and at 1 li of high-speed cruising of guide groove, its surface temperature can reach 800-900 DEG C, and the difference of the present invention and other anti-corrosion method is exactly at high temperature to carry out.On wire rod surface, form more Fe
3o
4, the iron scale of other composition of comparing, Fe
3o
4finer and close, be not easy to come off, so surface quality is improved.
Advantage of the present invention is, when the condition of high temperature, carries out corrosion protection processing on the surface of screw-thread steel wire rod after rolling.And traditional anti-corrosion method be all at steel in 500-600 DEG C, carry out steam treated.
Be added with the water of cooling medium, double thread steel wire rod recycles by retracting device after processing, and alleviates corrosion to equipment and the waste of corrosion protection liquid.
