Meanwhile, the invention is beneficial to solving the problems of dark color of the surface coating of the galvanized steel pipe, uneven thickness of the surface coating of the galvanized steel pipe and the like.
The technical scheme adopted by the invention is as follows: a zinc-aluminum alloy production method suitable for hot dip galvanized steel pipes comprises the following operation steps: 1. the zinc-aluminum alloy comprises the following chemical components in percentage by mass: 0.3 to 0.4 percent of Al, and the percentage content of impurities is less than: pb <0.005, Fe <0.005, Cd <0.002, Sn <0.002, Cu <0.002, and the balance of Zn; the zinc melting process flow comprises the following steps: preparing raw materials, melting zinc and aluminum in an intermediate frequency furnace, refining, deslagging, discharging, casting, demoulding, polishing and packaging; 2. smelting equipment, namely smelting equipment of an intermediate frequency furnace to realize molten zinc production; 3. the furnace lining material and the furnace lining sintering process adopt the modified rapping flat hammer, the flat hammer plate head is drilled with 4-5 round holes with the diameter of 10mm, and 4 knotting claws are welded on the working surface of the rapping flat hammer: all made of round steel with the diameter of 10mm and the length of 40 mm; 4. optimizing a baking furnace sintering process, and determining a baking furnace temperature curve: 0-220 ℃, and the time for heating is 0.5 hour; then the temperature is kept at 220 ℃ for 2 hours; 220 ℃ and 440 ℃, the temperature rise time is 0.5 hour, and then the temperature is kept at 440 ℃ for 2 hours; 440 ℃ and 660 ℃, the temperature rise time is 0.5 hour, and the temperature is kept at 660 ℃ for 2 hours; 660 ℃ and 880 ℃, the temperature rise time is 0.5 hour, and then the temperature is kept at 880 ℃ for 2 hours; 5. and (3) zinc-aluminum alloy production refining operation: the bottom of the intermediate frequency furnace is provided with the air brick, so that the slag removal operation can be realized by blowing argon or nitrogen at the later stage of zinc-aluminum alloy smelting; 6. treatment of aluminum segregation problem: the segregation problem can be solved by uniformly mixing zinc and aluminum by strong electromagnetic stirring action of the intermediate frequency furnace, pouring a zinc-aluminum alloy ingot, and further raising the temperature of aluminum liquid to 1050 ℃.
The invention mainly researches how to determine the zinc-zinc alloy components used for steel pipe galvanizing on the premise of ensuring the galvanizing quality. In the determination of the composition, less or no more expensive alloy is added. By looking up data, the surface of the coating can be brighter than that of a pure zinc layer by adding a small amount of aluminum into the zinc liquid. The Al in the zinc liquid is selectively oxidized to form a continuous Al layer on the surface2O3The surface of the film and the zinc liquid is not easy to oxidize and is smoother than a pure zinc bath, so that a brighter coating is obtained. Meanwhile, because the coating also contains aluminum, a layer of Al is formed on the surface of the coating2O3The protective film provides a physical barrier to the zinc layer to prevent the zinc from being oxidized by air, which is beneficial to maintaining the metallic luster of the zinc. After the aluminum content in the zinc liquid exceeds 0.005 percent, the brightness of the coating is steadily improved along with the increase of the aluminum content, and the aluminum content in the zinc bath is about 0.02 percent and reaches the highest value, but the brightness of the coating is not improved any more and even is slowly reduced after the aluminum content exceeds 0.02 percent. When the zinc plating is carried out at 465 ℃, only bottom slag with the aluminum content lower than 0.134 percent is obtained, and the bottom slag with the aluminum content higher than 0.134 percent is gradually converted into surface slag, thereby being beneficial to slag removal operation. Therefore, the aluminum content in the zinc liquid reaches more than 0.134 percent, which not only can keep the luster of the zinc metal coating, but also is beneficial to removing various zinc residues generated in the galvanizing process. Particularly, as the content of aluminum in the zinc metal liquid is increased, the fluidity of the zinc liquid is obviously improved, a thin and uniform coating is easy to obtain, and the reduction of the factory cost is facilitated. The method is suitable for zinc-aluminum alloy enterprises of the same type, and the zinc-aluminum alloy is an alloy formed by adding other elements such as aluminum and the like on the basis of zinc. The zinc-aluminum alloy has the advantages of low melting point, good fluidity, excellent corrosion resistance, beautiful appearance, favorable subsequent processing, relatively low cost and the like, and can be widely applied to the industrial and civil fields.
