Abstract
The invention discloses a production process of hot-dip copper zinc alloy plate. The hot-dip copper zinc alloy plate is composed of a steel plate base material and a copper zinc alloy coating. The production process comprises the following steps: washing the base plate, annealing, preparing a copper zinc alloy plating solution, hot dipping and post-processing, heating and stirring the copper zinc alloy, and keeping the temperature of the copper zinc alloy solution at 890-920 DEG C; heating the cold continuous rolling carbon steel base plate to more than 750 DEG C in an annealing furnace, and annealing and recrystallizing, performing surface reduction activation under a high hydrogen atmosphere, and performing a good conjugation reaction of the cold continuous rolling carbon steel base plate and the copper zinc alloy. The production process has the advantages of simple process, convenient operation, and good copper zinc alloy plating effect, gold colour and low processing cost and can be popularized easily.
Description
Technical field
The present invention relates to metal alloy compositions production technical field, especially a kind of production technique of hot-dip coating copper-zinc alloy plate.
Background technology
A ferrous materials major issue is in use exactly corrosion, the iron and steel that the whole world is lost due to corrosion every year reach ten million ton and.In the corrosion protection technology development process of ferrous materials, people recognize that coating technology is better than other technologies, are a kind of important, most widely used technology protecting ferrous materials.The quantity of whole world coating product, from 1,000,000 tons of nineteen fifty, more than 100,000,000 ton that is at the end, adds more than 100 times; In world's steel products, coating product accounts for 1/10th.Seeking the end of Iron And Steel Industry and human social, coating technology saving resource and the energy, emissions reduction and protection of the environment, promotion meat ached with natural harmony development etc. in demonstrate the effect become more and more important
World economy develops rapidly, the standard of living of the people improves day by day, the requirement of the people to life is also more and more higher, just popular a kind of color is called " local tyrant's gold " now, so-called " local tyrant's gold " this color is all made product by a lot of businessman, but for metal, " local tyrant's gold " on the market substantially all makes of copper zinc alloy, the electroplating technology more complicated of copper zinc alloy, and the waste water produced in electroplating process can cause quite serious pollution thus not advocate use electroplating technology to environment, therefore be badly in need of a kind of new technology and solve above-mentioned technological deficiency.
Summary of the invention
The invention provides a kind of production technique of hot-dip coating copper-zinc alloy plate.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of production technique of hot-dip coating copper-zinc alloy plate, hot-dip coating copper-zinc alloy plate is made up of substrate of steel plate and copper zinc alloy coating, comprise base-plate cleaning process, anneal, the preparation of copper zinc alloy plating solution, hot dip and aftertreatment, described substrate of steel plate is cold continuous rolling carbon steel substrate, the mass parts of described copper zinc alloy coating constituent is: Cu:15-25 parts, Si:0.3-0.5 part, Ni:0.2-0.5 part, Mg:0.5-0.9 part, Zn:73.8-84 part, Mn:0.5-0.8 part, to copper zinc alloy heating and stirring, copper zinc alloy solution temperature remains on 890-920 DEG C; Cold continuous rolling carbon steel substrate is heated to more than 750 DEG C and is carried out annealing recrystallization in annealing furnace, after under high nitrogen atmosphere, carry out surface reduction activation, cold continuous rolling carbon steel substrate and copper zinc alloy good combination are reacted.
Cold continuous rolling carbon steel substrate is 120-300min in the annealing furnace annealing recovery time.
In annealing furnace, in hydrogen reducing agent, hydrogen richness is 30%-55%.
The invention has the beneficial effects as follows: technique is simple, and easy to operate, copper zinc alloy coating is effective, color exactly likes very gold, and tooling cost is little, is easy to promote.
