Abstract
The invention discloses a rust-proof cover used for a horizontal strip coil and a use method thereof. The rust-proof cover used for the horizontal strip coil is characterized in that a gas phase rust-proof packaging material sheet is made into a tube shape; a rust-proof surface is arranged outwards; two ends of the tube shape are respectively folded back to the edge along the length and are combined with the length direction to form a closed loop channel; an elastic cord is preset in the closed loop channel to form a side fixing tightening device; the rust-proof cover has the following size that the length is equal to strip coil width plus strip coil external diameter plus 400-600mm, and the tubular diameter is equal to strip coil external diameter plus 100-200mm. The use method comprises the following steps: collecting into one bundle along the length direction, penetrating through the inner core of the horizontal strip coil, turning two end parts to the periphery of the strip coil, and fixing. The rust-proof cover has the characteristics that the rust-proof effect is obvious, and corrosion on the strip coil by the corrosive atmosphere of the environment can be effectively avoided; the transshipment requirement can be satisfied without removing a package; in the storing and hoisting period, uninterrupted whole course rust prevention is realized; the rust-proof cover is simple and quick to use, the efficiency of the rust-proof cover is 5-10 times of that of the traditional mode, and the starting time of the rust-proof packaging of the strip coil is in the first time period; the rust-proof cover can be reused; one rust-proof cover can be used for various specifications of strip coils of which the sizes are less than or equal to the above size so as to lower the rust-proof cost.
Description
Technical field
The invention belongs to metal and add inter process product rush-resisting material, a kind of Horizontal steel coil is protective case and the using method thereof of the antirust use of short-term during storage.
Background technology
The processing mode of metallurgy industry cold-rolling of steel plate plate is at present: cold rolling---annealing---smooth---rewinding oiling---packing,---annealing---(smooth)---coating processing---rewinding oiling---packing that the processing mode of coating sheet material is: cold rolling.Wherein smooth, smoothly to rewinding oiling, coating, process rewinding oiling, rewinding oiling in packaging process being annealed to, coil of strip need to be placed a period of time in factory building, short one, two day, long two, three weeks.Between this storage period; coil of strip is in air environment; easily be subject to environmental conditions; as the impact of the aggressive fumes such as moisture, oxygen, dust, tail gas, acidity, temperature, there is corrosion; especially for after annealing and dry coil of strip after smooth; without any corrosion protection measure, in the situation that plum rain season, damp and hot season and difference variation are large, very easily there is corrosion in surface.Once coil of strip corrosion, entire volume material will be scrapped, and the steel-making of carrying out above, hot rolling, the process such as cold rolling, all by vain, when producing a large amount of economic losses, have also caused the significant wastage of the energy.Therefore antirust in the course of processing of coil of strip is that each steel mill pays much attention to always, and the problem of having a bad headache.Steel mill all drops into every year a large amount of man power and materials and carries out the antirust control of process, but still time have corrosion to occur, major cause is that antirust cost and antirust technology are limit.
Need at present process antirust more be the coil of strip of horizontal placement, roll up mandrel to being parallel to ground.This Horizontal steel coil may need handling to arrive different places placement or to be processed during storage, therefore the inner core of coil of strip need to be exposed to drive a vehicle handling.Now steel mill can only drop into limited human resources based on the market competitive pressure to carry out process antirust, and the antirust technology using is at present mainly to adopt volatile rust prevention paper wrapper, and the problem of existence is that coil of strip required time of packing is long, an artificial about 5-10 minute.More when the coil of strip that needs are antirust, or ambient temperature sharply changes in the time of may producing condensation, and set assigned personnel have little time to carry out packaging operation, causes not and corrosion appears in the coil of strip of corrosion protection.Coil of strip outermost layer in manufacturing process generally can be dismissed in following process in addition, therefore to antirust, does not require, as carries out totally-enclosed packing, can cause certain waste.The coil of strip end Rustproof cover that up-to-date coil of strip process rush-resisting material also has CN203402499U to mention at present.This Rustproof cover greatest problem is that volume core is wrapped in cover, when handling, must open Rustproof cover, and now coil of strip must not obtain corrosion protection, is not suitable for antirust in handling process.
Summary of the invention
The object of this invention is to provide a kind of Horizontal steel coil Rustproof cover, be applicable to Horizontal steel coil in the course of processing, to protect coil of strip, between temporary transient storage period, corrosion does not occur, the coil of strip that is particularly useful for possibility handling between storage period is antirust.
A kind of Horizontal steel coil Rustproof cover, adopt gas-phase rustproof packaging material, it is characterized in that gas-phase rustproof packaging material sheet material to make tubulose, antirust face outside, in tubulose two ends limit portion respectively along the length edge that turns back, this edge also forms closed loop passage with length to combination, and a preset elastic cord in closed loop passage, forms fixedly tightening device of limit portion; The size of this Rustproof cover tubulose: length=width of steel coil+coil of strip external diameter+400～600mm, tubular diameter=coil of strip external diameter+100～200mm.
The using method of Rustproof cover for described Horizontal steel coil, it is characterized in that by antirust towards outside, a branch of along the harvest of drum length direction, from Horizontal steel coil inner core, penetrate, and pass from opposite side; Both sides cylinder end is translated in coil of strip periphery and is fixed; For the Rustproof cover with closed loop elastic cord, can Rustproof cover directly be bound round in coil of strip periphery by elastic cord; For end to end draw-string, the draw-string by stay cord buckle and control sling rope is strangled in coil of strip periphery; For the disjunct draw-string of head and the tail, by drawing the initial and end end of every side rope and controlling sling, draw-string is strangled in coil of strip periphery.
Principal feature of the present invention:
1, rust-proof effect is remarkable; can play desirable corrosion protection effect to steel roll end and interlayer; can effectively prevent ambiance; as the corrosion of aggressive atmosphere to coil of strip such as moisture, oxygen, dust, tail gas, acidic gas; especially can prevent when ambient temperature sharply changes the corrosion bringing due to coil of strip surface condensation.2, use after Rustproof cover of the present invention, coil of strip inner core keeps unimpeded state, and lifting fork hook can insert, and need not remove packing and can meet the transhipment needs while driving a vehicle handling.3, deposit with handling during realize uninterrupted omnidistance antirust.4, use is simple, quick; two people pack a coil of strip only needs approximately 30 seconds; be significantly less than a traditional personal anti-tarnish paper and pack the 300-600 time of second; efficiency is 5-10 times of traditional approach; and the initial time of coil of strip rust prevention packaging is got the jump on to very first time section, anti-condensation protection requirement when meeting more in time in situ temperature and sharply changing.5, Horizontal steel coil is reusable with Rustproof cover, reduces antirust cost.6, Rustproof cover can be used for this dimensions and the corrosion protection of the plurality of specifications coil of strip that is less than, applied widely.
