The invention has the following positive beneficial effects:
1. the invention combines the currently common 3003 aluminum alloy brand, optimizes and adjusts the chemical components, adjusts the content ranges of Cu and Mn, and simultaneously introduces Zr, la and Ce 1:1, the mixed rare earth element purifies the aluminum matrix element, simultaneously the second phase is uniformly and finely precipitated (refer to a metallographic analysis chart in a figure 3), and the subsequent process control is utilized to ensure that the yield strength of the material is slightly higher than that of a 3003 annealing state aluminum rod, so that the segregation degree is greatly reduced, the material is prevented from being subjected to homogenizing annealing, the surface oxidation risk is reduced, the speed is unchanged during continuous extrusion, and the yield is effectively improved.
2. The invention strictly controls each step, the sequence and the temperature control parameters of each step in the manufacturing process (see the process flow chart in figure 1), so that the aluminum liquid processing process is strictly controlled, the element segregation and the second phase precipitation are extremely uniform, and the temperature of the casting blank can be effectively controlled according to the subsequent performance requirements.
3. The belt casting has a fast cooling speed, so that the segregation of alloy elements is difficult to avoid, and the segregation has great influence on the subsequent processing nonuniformity of the alloy. In the continuous casting stage, molten aluminum enters a wheel belt type casting machine through a casting ladle, the temperature of the molten aluminum is controlled to be 680-720 ℃, casting is divided into three cooling water areas (see a cooling water partition control chart in figure 2), the water flow and the pressure of each cooling water area can be independently controlled, and the temperature of a casting blank coming out of a crystallization wheel is 480-570 ℃ and fluctuates within +/-10 ℃; the product performance is stable, the structure is free from defects, the second phase is uniform and fine by strictly controlling the fluctuation of the temperature of the casting blank, the annealing step is not needed before the flat tube is extruded, the surface oxide layer is reduced, the phenomena of scratch and air leakage and aluminum scrap pipe blockage of the extruded finished product are avoided, and the purposes of reducing energy consumption and improving the yield are achieved.
The specific element components of the invention are optimized as follows:
the Cu element can be dissolved in the aluminum matrix and form fine CuAl when precipitated 2 And meanwhile, the strengthening effect on the aluminum alloy is obvious, but the corrosion resistance of the aluminum alloy is reduced, so that the Cu element is controlled to be 0.05-0.2wt%.
The Mn element can improve the strength of the alloy in a small range and can effectively improve the plasticity and corrosion resistance of the aluminum alloy, but because the supercooling degree of the Mn element in the aluminum is large and the Mn element is easy to segregate in the crystal during the solidification process, homogenization annealing is generally carried out during subsequent use. The invention controls the Mn content to be 0.20-0.80%, and avoids uniform postannealing while improving the corrosion resistance of the aluminum alloy. Experiments prove that the proportion of manganese Mn element and copper Cu element is controlled to be (5-7): 1. when the corrosion resistance and the strength are matched recently.
Zirconium Zr element can make the crystalline grain of aluminum alloy obviously refine, but zirconium Zr is comparatively expensive, easily volatilizes in aluminium simultaneously, so add a small amount of RE rare earth element simultaneously, reduce zirconium Zr's addition, reduce zirconium Zr's volatilization, both proportions are 1:1, all are controlled below 0.2wt percent, and the effect is best
Since Si element has low solid solubility in aluminum alloy, and easily forms hard single crystal silicon when precipitated, and has high hardness, ti and B form TiB by controlling the solid solubility to 0.05wt% or less 2 The crystal grains can be refined, but aggregation is easy to occur, surface scratches are easy to form when the flat tube is extruded subsequently, and in the case of zirconium Zr and rare earth RE, ti and B are controlled to be less than 0.005wt% as impurities. In general, it is preferable to control the Si + Ti + B to 0.0005 to 0.005%.
Alkali metals such as Li, na, ca and the like are common impurity elements for aluminum alloy smelting, and the weight percentage of a single impurity element is controlled to be less than 0.001 wt%.

example 10 to example 13:
examples 10 to 13 are different from example 1 in that: the total pressure and flow are not changed during casting, but the flow of the three cooling areas is different in subarea, and the specific steps are as follows:
example 14:
example 14 is an unannealed 3003 alloy rod, distinguished from example 1 by not being identical in elemental composition;
