Description
Technical field
The invention belongs to steel processing technique fields, are related to a kind of anacidity physical treatment strip oxide skin production line.
Background technique
Method of chemical treatment is used currently, industrially removing to the oxide of original tape steel surface, that is, utilizes strong acid and oxidation
The chemical reaction of iron removes oxide.However, this acid washing method not only complex process, it is at high cost, have certain safety hidden
Great pollution is brought to environment when suffering from, and handling waste material.
Summary of the invention
The purpose of the present invention is to solve the above problem, provides a kind of anacidity physical treatment strip oxide skin production line, tool
There is a kind of anacidity physical treatment strip oxide skin production line for the features such as at low cost, process is simple, non-environmental-pollution.
The object of the present invention is achieved like this: a kind of anacidity physical treatment strip oxide skin production line, the production line
It is realized by following steps: 1) uncoiling: the original tape steel not derusted being sent to uncoiler and carries out uncoiling；2) it shearing, butt welding: will end
Material head, the material irregular Partial Shear of tail of coiled strip steel fall, and then weld the material head of two construction materials contracts and material tail, guarantee strip
Continuity when walking；3) loop storing: it will be stored to successional strip feeding loop is soldered, and guarantee that subsequent handling will have
Sufficient raw material；4) rectify a deviation: strip passes through S rod, and make belt steel flating equilibrium under tension enters next process,
Guarantee that strip will not sideslip；5) it heats: strip is sent into high temperature furnace, at the uniform velocity walking carries out balanced heating, the strip speed of travel
It is 80 ms/min, in-furnace temperature control is heated in 800 degree or so, furnace using high frequency boiler tube, and fuel can use coal, petroleum, high frequency
Electricity, natural gas etc.；6) cooling: strip goes out after high temperature furnace, carries out while walking up and down and rectifying a deviation on cooling frame air-cooled；7) it rectifys
Flat: the strip cooled down carries out leveling by jockey pulley, guarantees the planarization of belt steel surface；8) break unicorn: smooth complete strip into
Enter scratchbrusher, one layer of unicorn (the usually iron rust of belt steel surface, iron monoxide and ferrous oxide) of belt steel surface is dredged
Pine, the speed that strip passes through wire brush is 80 ms/min；9) it grinds: the strip after broken unicorn is sent on sand conveyer belt, pass through
It crosses and grinds back and forth, further remove the iron oxide (usually ferric oxide) of belt steel surface, grinding rate is designed as 80 ms/min
Clock；10) rinse: the strip ground rinses the iron oxide of one layer of loosening of belt steel surface attachment, oxygen after flushing by clear water reserviors
Change iron and is deposited in bottom of pond；11) it is passivated: the strip rinsed being sent into passivation pool, belt steel surface is passivated, prevented secondary
Oxidation, passivating solution use the sodium hydroxide of 20% concentration；12) it winds: blanking winding molding after strip has been passivated.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is anacidity physical treatment strip oxide skin production line structural schematic diagram of the present invention.
Uncoiling: supreme uncoiler 1 is sent to carry out uncoiling the original tape steel not derusted.
Shearing, butt welding: the material head for ending coiled strip steel, the material irregular portion of tail are cut away using shearing 2 sub-cut of bonding machine, so
The material head of two construction materials contracts and material tail are welded afterwards, guarantee continuity when strip walking.
Loop storing: it will be stored to successional strip feeding loop 3 is soldered, and guarantee that subsequent handling will have sufficient original
Material；.
Correction: strip passes through S rod tensioner 4, and make belt steel flating equilibrium under tension enters next work
Sequence guarantees that strip will not sideslip.
Heating: strip is sent into high temperature furnace 6, and at the uniform velocity walking carries out balanced heating, and the strip speed of travel is 80 ms/min
Clock, in-furnace temperature control are heated in 800 degree or so, furnace using high frequency boiler tube, and fuel can use coal, petroleum, high-frequency electrical, natural gas
Deng.
Cooling: strip goes out after high temperature furnace 6, carries out while walking up and down and rectifying a deviation on cooling frame 7 air-cooled.
Leveling: the strip cooled down carries out leveling by the jockey pulley of tensioner 8, guarantees the planarization of belt steel surface.
Broken unicorn: smooth complete strip enters scratchbrusher 9, by one layer of unicorn (usually iron of belt steel surface of belt steel surface
Rust, iron monoxide and ferrous oxide) carry out loose, the speed that strip passes through wire brush is 80 ms/min.
Grinding: the strip after broken unicorn is sent on sand conveyer belt 12 by tensioner 10 and skin pass mill group 11, is passed through
It grinds back and forth, further removes the iron oxide (usually ferric oxide) of belt steel surface, grinding rate is designed as 80 ms/min.
Rinse: the strip ground enters in clear water reserviors 15 by tensioner 13, and cleaning brush 14 rinses belt steel surface attachment
One layer loosening iron oxide, iron oxide is deposited in bottom of pond after flushing.
Passivation: the strip rinsed being sent into passivation pool 16 and is passivated to belt steel surface, secondary oxidation is prevented, and is passivated
Liquid uses the sodium hydroxide of 20% concentration.
Winding: strip passes through drying box 17 after being passivated and tensioner 18 enters loop 19, using 20 He of tensioner
Hydraulic transverse shearing machine 21 enters the winding molding of winder 22.
