Aluminum sheet in the production process of rendering a lot of harm, scratches, rubs and so on, which is when the aluminum plate from flowing out of the membrane pores in the process will be presented, as well as perhaps in the future use of the processing takes place in the process this is only the appearance of scars, the main reason is there are several causes of.
1. In the production process, from swing bed generals dragged down abrasions aluminum sheet formation.
2. The transport process of aluminum sheet, the mutual information between the amount of conflict will be deformed.
3. In the time-division operation, there are some solid debris belt material, and then to touch the aluminum sheet after a certain hazard occurs.
4. Before the aluminum plate tracks, present some debris on the track, perhaps within the graphite hard object, will be on the aluminum sheet forming a certain hazards.
5. When will the bumps in the process of discharging speed can not be too soon, too fast to put the aluminum sheet on the bed.
These are some of the production will be presented on these abrasions nor is not resolved, following the introduction of several solutions.
1. The production process must be strengthened demand for ingot quality control.
2. The aluminum sheet material in the box seat must be placed to be reasonable, so that we can be useful to reduce conflict.
3. nitride mold timing must demand protection, we can improve the quality of the mold.
4. Do not because it is not Reflections aluminum plate gently, and the best is not free to drag aluminum sheet. Be sure to use between aluminum sheet and aids.
5. soft things apart, touch less and assistive devices can be useful to fall hazards.

how can we distinguish the fake or real aluminum alloy fastly?
Since more and more aluminum alloy products appear after another, it's not easy to tell when we select it, a lot of unscrupulous manufacturers took the opportunity to make trouble, aluminum alloy mixed fish heads on the market, real to the enemy, indeed a headache for consumers. But how can we distinguish the fake or real aluminum alloy fastly?
1. There are two sides of aluminum alloy:sub-sided and single-sided.
2. At the time of purchasing it,you need to observe its surface and color, whether the appearance is smooth, the color is gorgeous.
3. aluminum alloy glue seam neat, decorative aluminum plate when building exterior, between the plates must usually have a slit width.
4. If the appearance of aluminum alloy with deform and dark,these are defective.
5. You can analyze aluminum alloy, the primary problem is on the bottom of the aluminum plate , the dealer would recommend that you purchase the underlying data is the high-density wood panels and more similar. It's outdoor use, their life is very weak, will deform easily after wind, sun and rain. The underlying data are already deformed, do not be fooled by dealers, must hold what you want to buy.

How to clean pattern aluminum plate professionally?
Pattern aluminum plate in life is becoming more common, and the role of pattern aluminum is also growing, after the washing process will become more beautiful pattern aluminum alloy in the production process will often appear loose ingot or blowhole and other defects, to the production process of a lot of trouble. Following small and you a brief introduction pattern aluminum plate washing deal with it, how to be more professional washing pattern aluminum plate.
Start porosity is concerned, it is mainly among aluminum ingot circular hole, the reason is mainly formed when dissolved gas is always in a state of saturation, and the melt, there are still a lot of non-metallic inclusions It slows things, so that the gas in the process of casting floating rate, bubbles will remain in the pores of the ingot.
Loose ingot form factors are two: First, there is no removal of loose melt gases; the second is a loose contraction generated when it is related to gas and melt, generally when we conduct analysis mainly based on gas content of the melt and the casting speed.
In fact, we can also use a liquid feeding mode, so it reduces the metal in the furnace residence time, can make the inside of the gas furnace in the continuous saturation effect to get a good release and decomposition, but also good control generation of impurities, reduce non-metallic slag material.
1, after alkaline etching, the aluminum plate surface pattern will be left Dalian alkaline etching grooves film, which we call water alkaline etching after. Pattern aluminum plate base after etching is more difficult to clean, and first of all we want in favor of cleaning products point of view, the first tank to maintain the temperature of the water and alkaline water is not going to replace. After washing twice, in order to make a better cleaning effect, we can be appropriately stirred. After washing twice watching work How much amount may be, it can not handle the overflow.
2, it is necessary to go through at least two water washing step is called neutralized. This washing we recommend using circulating water cleaning, doing so in order to protect normal oxidation tank when, because in and the nitric acid tank, if it is brought into the oxidation tank, then there may not form an oxide film, or an increase in the oxidation tank impurities, this will accelerate the aging of the oxidation tank.
3, a simple two washing, washing after chemical polishing after chemical polishing will be from some residual liquid, in order to better clean, small second sink recommend using circulating water, the first water tank maintained at a temperature on the line.

TC4 titanium rod forging process analysis
Large deformation resistance of titanium alloy, chemically active, thus forging process has special problems and difficulties. First, the microstructure and properties of titanium forgings for forging thermal parameters are very sensitive. Titanium forging temperature range is relatively narrow in the forging process, with the increase of strain rate, its deformation resistance increased significantly, showing a strong strain rate sensitivity. Second, the thermal conductivity of titanium alloys is poor, in the forging process prone to localized overheating, resulting in a large temperature difference between inside and outside, inside and outside the degree of deformation of the blank exacerbate uneven distribution, resulting in cracking the forging process, and in severe cause product obsolescence. Therefore, studying the effects of different forging process on the microstructure and mechanical properties of titanium alloys, to seek a reasonable forging process to forming titanium forgings production has important practical significance.
TC4 titanium alloy have excellent performance in the aerospace, automotive and medical and other fields has been widely used, is the most widely used as a two-phase α + β type titanium alloy. Scholars of the various properties and processing technology titanium launched a lot of research, however, the system of different forging process on TC4 alloy microstructure and mechanical properties of a few. Researchers studied the β forging, forging close β and (α + β) two-phase region forging affect three different bars forging process on microstructure and mechanical properties of TC4 titanium alloy microstructure, more optimization program with a view to forging process selected for Production TC4 titanium alloy forgings to meet the requirements to provide a reference.
TC4 alloy material size experiment is Φ100mm × 450mm of forging stock, as measured by optical method (α + β) / β transformation point (Tβ) to 990 ℃.
In order to study the influence of the forging process on microstructure and mechanical properties of TC4 Titanium Alloy, forging stock will be divided into three sections, namely conventional forging (Tβ-60 ℃), near-β forging (Tβ-20 ℃) and β forging (Tβ + 40 ℃) process test, deformation of 50%. Forging equipment for 3t free forging hammer. After forging, the process to get through three kinds of forging 900 ℃ × 1h / AC + 600 ℃ × 4h / AC dual heat treatment. After the heat treatment, the TC4 titanium alloy forgings intercept metallographic sample, tensile specimens and impact test specimens, the microstructure was observed under the microscope. Using image analysis software to complete and other microstructure parameters axis α phase content and secondary slice thickness α phase of quantitative statistics. The results showed that:
(1) TC4 alloy forged by α + β, near β and β forging three kinds of forging process after forging, respectively equiaxed structure, mixed structure and lamellar tissue.
(2) α + β forging, strength after forging close β and β forging TC4 titanium alloy bars fairly, but after forging and near α + β β β forging forging relatively high plasticity, but β forging TC4 titanium rod Best toughness. After nearly β forging TC4 titanium alloy bars show the best mechanical properties.
(3) tensile specimen fracture TC4 titanium alloy bars under three kinds of forging process showed a ductile fracture mechanism, α + β forging and near-β forging with deep and evenly distributed equiaxed dimples, and β forging alloy exhibits a more flat and elongated dimples.
