Background technology
With the rising of metallic tin price and from the angle for saving metals resources, on the premise of tin plate sheet surface characteristic is ensured, the positive slimming development of tin layers of tin plate, current main product is 2.8g/m2And less than 2.8g/m2Tin layers, be mainly used in beverage/food can body and top bottom, only when stronger food cans are acted on for some electrochemistry detins, to be higher than 5.6g/m using tin coating weight2Thickness coating.But, the thinning possibility for also increasing its surface characteristic variation of tin layers, this is due in the case where tin amount is less, it is difficult to the whole tin plate sheet surface of uniform fold, and tin layers is uneven, its follow-up alloy-layer, the form of passivation layer can be influenceed, and then have influence on the surfaces characteristic such as its corrosion resistance, tack.
Main flow electrotinning lines generally carry out tin plating, the method technology maturation, product quality stabilization using phenolsulfonic acid electroplate liquid, but because containing benzene in plating solution, the feature of environmental protection is poor；Pyrovinic acid electroplate liquid is a kind of emerging plating solution of tin plating board industry, in addition to environment-friendly advantage, it is also equipped with the low advantage of electroplating operations wide ranges, power consumption, but in specific commercial Application, also the characteristics of it is high to substrate requirement, electroplating effect is whard to control is exposed, especially when flash plating is produced, easily there is the problems such as uneven tin layers, plating leakage.
In the prior art, generally increase side cover in electroplating process, stop the excessively intensive power line of edge by side cover to eliminate the edge thickening effect of tin coating, Chinese patent application CN200710037328.0, the method for improving electroplating evenness, using a baffle plate with windowing is put between the to-be-electroplated surface and anode as negative electrode, the rib connected together with baffle plate is put on the edge of baffle plate, the power line for bypassing baffle edge is eliminated with rib.But above method is to eliminate the tin coating weight deviation for improving tin plate edge and middle part, to tin coating weight >=2.8g/m2Thickness coating product have obvious effect.But in flash plating, particularly tin amount is in 0.9~2.2g/m2Product on, because total current is smaller, the intensive influence of its edge power line is limited, and edge will not cause to significantly affect with middle part difference on the table characteristic surface of tin plate；The method is only through the tin amount difference that physical barriers are avoided on macro position, to microcosmic tin layers uniformity without any beneficial effect.
The tin plating method of a kind of metilsulfate tin plating electrolyte and steel band or steel plate is carried in the Chinese patent application of Chinese patent application publication No. CN102162110 A, it discloses a kind of pyrovinic acid electrotinning formula of good stability, comprising 30~120g/L of stannous methanesulfonate, 60~180g/L of pyrovinic acid, 1~10g/L of cerous sulfate phenol, 0.1~2g/L of antioxidant, 5~10g/L of brightener, 5~15g/L of surfactant, steel band or steel plate transporting velocity are 3~9m/s during plating, plating temperature is 15~60 DEG C, and current density is 6~20A/dm2, degreasing and acid pre-pickling treatment are carried out before plating to steel band or steel plate, strip or steel plate after plating carry out soft heat, passivation and coating oiling post processing.The method focuses on to describe its plating process, in particular, provide a kind of good stability, and the electroplate liquid formulation and application method of tin coating brightness, corrosion resisting property and welding performance can be improved, the composite coating properties evaluation result and the requirement to tinning substrate obtained to it does not carry out disclosure.But from the point of view of disclosed electroplate liquid formulation, each component concentration is higher, especially main salt concentration, and this kind of plating solution is more suitable for the plating of Gao Xiliang, for 2.8g/m2Easily there are tin layers during following coating coarse, influence compactness of electroplating.

A kind of manufacture method of the cold rolling tin plate of flash plating, the method includes：
It is that the cold rolling hard steel plate that rolls of 0.17~0.35mm carries out vertical continuous annealing furnace annealing, smooth, scrub, electrotinning, soft heat, batches the step of obtaining finished product to thickness, wherein,
It is described it is cold rolling roll hard steel plate chemical component weight percentage be：C：0.05%~0.10%, Si≤0.04%, Mn：0.2%~0.4%, P≤0.02%, S≤0.02%, Alt0.02%~0.05%, O≤0.004%%, N≤0.0035%, balance of Fe and inevitable impurity element, lower yield strength RPLIt is 750~850MPa；
The annealing temperature of the annealing steps is 550 DEG C~620 DEG C, and annealing time is 60s~120s；
The planarization step is that Stand Mill four-roller wet type is smooth, and working roll uses chrome-plated roller, and it is the electric spark texturing roller of Ra1.2~1.6um that 1 frame working roll uses roughness, and roll-force is 500~600t；It is the grinding-roller of Ra0.3~0.5um that 2 frame working rolls use roughness, and roll-force is 300~450t, and smooth elongation percentage is 1%~2%；The leveling precision spray flux of 1 frame working roll and 2 frame working rolls is 15~20L/min in formation process；
The scrub step is to scrub surface of steel plate with brush roll in 40~60 DEG C of demineralized waters；
The electrotinning step is electroplated for low current density, using the pyrovinic acid system of insoluble anode, Sn in plating solution2+10~20g/L of concentration, pyrovinic acid free acid concentration is 40~60mL/L, and electroplating temperature is 40 DEG C~50 DEG C, and current density is 8~20A/dm2；
The reflow step be resistance reflow it is combined with induction reflow combine soft heat, reflowing temperature is 260 DEG C~280 DEG C, and Reflowing Time is 3~5s.
The reasons why production technology that the present invention takes, is as follows：
1st, annealing temperature and annealing time set
Recrystallization annealing is primarily to eliminate anisotropy in processing hardening, all kinds of defects of crystals and the mechanical property of generation in cold-rolled process etc., and the setting of annealing temperature mainly considers the recrystallization temperature and product performance demands of strip, the cold rolling hard steel plate that rolls of present invention setting is annealed in vertical continuous annealing furnace（Soaking zone）Temperature range is 550 DEG C~620 DEG C, and annealing time is 60s~120s.
2nd, flattening technological parameter setting
Cold rolling levelling technique is that the steel band by recrystallization annealing is carried out to be processed under minute-pressure, and purpose has three：One is the yield point elongation that carbon aluminium-killed steel is eliminated by the setting of smooth rate, it is ensured that the mouldability of material；Two is the template of steel plate after improvement annealing；Three is that the roughness required by surface of steel plate is given by leveling roll.
The present invention is smooth using Stand Mill four-roller wet type, neatly controls the roughness of strip.Found by repetition test and theory analysis, the roughness of belt steel surface depends on planisher 1, the collective effect of 2 frames, and strip will obtain suitable roughness, it is necessary to using texturing roller by the way of grinding-roller is combined；If can obtain roughness higher using only texturing roll strip, the uniform fold to follow-up flash plating is unfavorable；Though can obtain suitable roughness using only grinding-roller, surface of steel plate is all rendered as the gully pattern that grinding-roller is caused, and causes steel plate rolling lines thicker, influences the attractive in appearance of tin graphed sheet.The present invention sets the electric spark texturing roller that 1 frame working roll uses roughness as Ra1.2~1.6um by experimental study for many years, and roll-force is 500~600t；It is the grinding-roller of Ra0.3~0.5um that 2 frame working rolls use roughness, and roll-force is 300~450t, and smooth elongation percentage is 1%~2%, and smooth elongation percentage is 1%~2%.
Roller matching method described in the invention has to be used in combination with roll-force distribution, can not otherwise reach effect of the invention, because planisher technique determines the surface texture of tinning substrate, surface texture directly affects the plating process of thin layer of tin again.In smooth theory, the surface texture of steel plate depends on roll replication rate, and replication rate is mainly influenceed by roll pattern and roll-force.Applicant determines that under current parameter setting the replication rate of leveling roll is only possible to guarantee and obtains most suitable surface texture by test of many times.Otherwise, the pit pattern of the excessive then roller texturing of 1 frame replication rate is too deep, and when low tin amount coating is produced, tin layers are difficult to covering pit and cause to reveal iron, influence tin-plated board corrosion-resistance and brightness uniformity；Replication rate is too small, can decline the RPC values of steel plate, the tack of final influence tin plate and paint film.
The spray of above-mentioned leveling precision is also the key for completing the step, because wet jetting piles have without the big effect of dust, rolling lubrication, it is had more smooth, fine and smooth surface microstructure than dry flat, and rolling is laborsaving, and roller consumption is low.Spray flow is limited in 15~20L/min because the flow of leveling precision directly affects planarization effects by the present invention.Flow is excessive, and rolling lubrication is good, and formation process easily occurs steel plate elongation percentage and leaps high and be broken, and causes fault in production；Flow is too small, and rolling lubrication is not enough, and formation process roller consumption is high, increases cost and influence rhythm of production.
The present invention is using model PTA-NS（M）Leveling precision, leveling precision concentration be 2%.
3rd, parameter setting is scrubbed
The purpose of scrub is thoroughly to remove the foreign matter remained between substrate surface profile.Wet jetting piles are easy to get to the fine and smooth surface of profile due to the presence of leveling precision, but the presence of leveling precision also can increase surface of steel plate organic substance residues, it is therefore necessary to introduce scrub, and surface of steel plate is cleaned deeper into ground using the mechanism of bristle.Show that cleaning performance is optimal during 40~60 DEG C of water temperature, and the residua content of surface of steel plate must reach 20mg/m after scrub by lot of experiments checking2Below.
4th, electrotinning parameter setting
Present invention plating process of tin uses insoluble anode, and compared to soluble anode, the long service life of insoluble anode is fixed without frequently replacing, and Anode-cathode Distance, and the uniformity to coating is more favourable.
The present invention is electroplated using low current density, can effectively improve the uniformity of tin layers distribution, reduces uncoated dot.Electrotinning process nature is electro-deposition of the tin ion on by iron-based body, and according to theory of electrodeposition, the tin ion in plating solution is deposited into metallic tin to be needed to experience two processes of electrocrystallization forming core and nuclei growth, and electrocrystallization forming core exactly divalent tin ion（Sn2+）Electronics is obtained in the belt steel surface for doing negative electrode become metal tin atom（Sn）Process.When multi-pass is electroplated, the point of discharge of belt steel surface is that nucleus growth point can change with the change of passage, fails to obtain the point of enough forming core energy in certain passage and has an opportunity forming core again in other passages, so as to avoid the deposition of tin layers uneven.
Simultaneously as pyrovinic acid plating solution good covering power and dispersibility, it allows current density range wider, and applicant is confirmed under the bath system of pyrovinic acid by repetition test, Sn in plating solution2+10~20g/L of concentration, pyrovinic acid 40~60mL/L of free acid concentration, 40~50 DEG C of electroplating temperature, current density are controlled in 8-20A/dm2, the metal electrodeposition particle for obtaining is finer and close, uniform.
5th, soft heat parameter setting
Joint soft heat refers to the soft heat mode that induction reflow and resistance reflow are combined, this method avoid pure resistance soft heat firing rate is slow, the shortcoming that tin is oxidizable, but also with the fast advantage of pure induction reflow firing rate.
Melting temperatur and time control are fully to be melted in order to ensure tin layers and form the metal level of flowing in matrix surface, fill and lead up the coating crystal grain space produced in electroplating process, while ensureing the suitable growth time of alloy-layer.Reflowing temperature is too low, and metallic tin is not enough to melting, too high, can accelerate the oxidation of tin, brings other adverse consequences；Heat time is too short, cannot form enough alloy tins, unfavorable with corrosion resistance, and long then pure stannum layer is reduced, and influences the welding of tank process processed.By reflowing temperature control between 260~280 DEG C, Reflowing Time was controlled at 3~5 seconds the present invention, can not only have been obtained enough thick fine and close tin iron alloy layers but also can have been retained enough pure stannum layers, the need for can simultaneously meeting anti-corrosion and welding.
The thickness that the present invention is obtained is the cold rolling tin plate of 0.17~0.35mm flash platings, and its microscopic structure is ferrite and free cementite, and grain size number is I8.5~I9.0 grades, lower yield strength RPLIt is 300MPa~400MPa, tensile strength RmIt is 350MPa~450MPa, elongation after fracture A50It is 20%~40%；The tin plating layer weight of steel plate one side is 0.9~2.2g/m2, tin coating weight difference≤0.2g/m in unit area2, alloy tin weight is 0.35~0.65g/m2, porosity≤9mgFe/dm2。
The present invention has following good effect compared to existing technology：
1st, the present invention produces the flash plating tin plate of excellent performance, tin amount difference≤0.2g/m in unit area by the process combination of reasonable set flattening process, cleaning before copper plating, activation, low current density plating and soft heat hardening2, coating uniformity is good.
2nd, the present invention can effectively solve the problems, such as existing pyrovinic acid system flash plating layer porosity it is high, it is easy occur point rust, while overcome again traditional phenolsulfonic acid plant process not environmentally, the problem of high energy consumption.
3rd, implementation method of the present invention is easy, simple production process, slightly improves being capable of achieving in conventional Tin-Plating Production Line.
