Abstract
The invention provides an aluminum profile for greenhouse engineering, which comprises magnesium, silicon, titanium, boron and aluminium, and the contents are 0.58-0.62% of magnesium, 0.39-0.43% of silicon, 0.1-0.2% of titanium, 0.1-0.2% of boron, 0.2-0.3% of impurities, and the balance of aluminium. The invention selects an optimal component formula, controls the component contents of the alloy, significantly improves the material strength, and greatly improves the material plasticity.
Description
Technical field
The present invention relates to a kind of greenhouse engineering aluminium section bar.
Background technology
Along with energy shortage, energy-saving and emission-reduction have become a fundamental state policy of China; On the other hand, along with the development of science and technology, the utilization of sun power is more and more extensive, and especially greenhouse engineering progressively is familiar with by people, and is applied to every field, as agricultural science and technology, medical body-building, flowers kind grow, aquaculture etc.The material used for traditional greenhouse engineering is mao bamboon, steel pipe etc., and these material corrosion resistance are poor, Wind-Pressure Resistance ability, ornamental relatively poor, and greenhouse engineering is mainly used on the extensive structures such as green house of vegetables.
Summary of the invention
The invention provides a kind of greenhouse engineering aluminium section bar, it not only selects best composition prescription, controls the component content of alloy, has both significantly improved the intensity of material, has greatly improved again the plasticity of material.
The present invention has adopted following technical scheme: a kind of greenhouse engineering aluminium section bar, and it comprises magnesium, silicon, titanium, boron and aluminium, the content of magnesium is that the content of 0.58～0.62% silicon is 0.39～0.43%, titanium is 0.1～0.2%, boron content is 0.1～0.2%, impurity 0.2-0.3%, and all the other are aluminium.
The content of described magnesium is 0.6%, and the content of silicon is 0.41%, and titanium is 0.1%, and boron is 0.1%, and impurity is 0.29%, and all the other are aluminium.
The present invention has following beneficial effect: add magnesium in the alloy material of the present invention, adopt the special magnesium instrument that adds to add when adding, thereby so effectively reduce the scaling loss of magnesium, improve the metal Mg utilization, guarantee the composition precise control.The present invention adds magnesium in aluminium, silicon and trace amount of titanium, boron, the effect of magnesium in metal, has the formation strengthening phase, improve intensity, increase the surface treatment properties of metallic substance, the effect of silicon in metal has the formation strengthening phase, improves intensity, increases the flowability of metal, improve the interior tissue of metallic substance, titanium and boron play Grain refinement, improve the interior tissue grain size of metallic substance, and the homogeneity of internal organizational structure, so not only select best composition prescription, control the component content of alloy, both significantly improved the intensity of material, greatly improved again the plasticity of material.
Embodiment
The invention discloses a kind of greenhouse engineering aluminium section bar, it comprises magnesium, silicon, titanium, boron and aluminium, and the content of magnesium is 0.6%, and the content of silicon is 0.41%, and titanium is 0.1%, and boron is 0.1%, and impurity is 0.29%, and all the other are aluminium.
The invention also discloses a kind of greenhouse engineering preparation method of aluminium section bar, it may further comprise the steps: step 1, carrying out composition calculates: calculate according to alloy ingredient content, determine various alloying element additions, wherein the content of magnesium is 0.6%, and the content of silicon is 0.41%, titanium is 0.1%, boron is 0.1%, and impurity is 0.29%, and all the other are aluminium; Step 2, accurately feed intake according to calculation result, because the fusing point of each alloying element is different, at first throw in aluminium ingot, behind aluminum ingot melting again by the special magnesium that adds, magnesium is joined in the aluminium water, at last titanium and boron adding are carried out refining, the method for its refining is to pass into high pure nitrogen, and sylvite or sodium salt, applied chemistry is reacted and voltage divider principle, reaches the purpose of slag making, slagging-off, leaves standstill at last; Step 3 is carried out hot direct casting fabrication technique with the alloy material after leaving standstill and is made the greenhouse engineering aluminium section bar, and the casting temp of hot direct casting fabrication technique is that 720 ℃, casting speed are: 100mm/min, adopt foam ceramic filter during casting.
