1
Preparation of raw materials - including visual inspection of raw materials, chemical composition analysis, ingredients and weighing of various ingredients according to the calculation of ingredients. In addition, also includes refining agent, metamorphic agent drying and weighing.
2
Smelting - adding materials in a furnace in a certain order to melt them into alloys of uniform chemical composition.
3. Pre-furnace test -- after the alloy is evenly melted, sample and test to check whether various chemical components meet technical standards.
4
Adjustment of composition - If the chemical composition of one or more alloys is found to exceed the technical standard after testing, adjustment shall be made to make the chemical composition meet the technical standard.
5
Refining - After chemical composition requirements, a refining agent is used to remove dissolved gases and entrained solid particles from the alloy.
6
Refining metamorphism - adding appropriate refiner and modifier to aluminum alloy liquid to improve mechanical properties and mechanical cutting properties of the alloy, etc.
7
Casting -- casting aluminum alloy with qualified chemical composition, good metamorphism effect, gas content and slag content to meet the requirements into ingot, into bales.

Euro Display ( http:// ) installed the biggest and highest outdoor advertising LED screen in Italy during a spectacular installation in Milan: with a surface of almost 100sq m and a weight of 13 tons, the LED screen was lifted Up 50 meters by a huge 400 tons crane and fixed by 2 specialized technicians equipped with special climbing gear.
The installation itself took about 4 hours, including the lifting, fixing and start-up but the process was postponed 3 times during the day due to the strong wind onsite that almost forced us to delay the installation to another day.
It brings together one of the most prominent locations in Italy, with the biggest advertising LED screen ever installed outdoor in the country. Euro Display's management software enables the LED screen to visualize hourly updated local/national weather forecasts, international news and live videos to attract Audiences with updated and interactive content. The LED screen is programmed to self adjust its brightness to any environmental conditions.
The LED screen was designed by Euro Display technicians to deliver the highest image quality, even at extreme viewing angles due to the height at which the screen is installed.
As the customer didn't want to incline the LED screen, the company had to design a new frontal protection system to ensure an amazing side view angle of 170∑ without any distortion.
The huge LED screen was installed in Via Alcide De Gasperi and it is visible from the highly trafficated freeway exit of Viale Certosa, the very first exit which leads downtown to the FieraMilanoCity Exhibition Centre.
The installation procedure was impressive: the huge structure weighting more than 13 tons was lifted up to 50 meters where 2 technicians equipped with special climbing gear proceeded with the mechanical installation.
With almost 100sq m and a resolution of 800 x 640 pixels and over half a million highly selected LEDs, Euro Display's LED screen will become a landmark in sight of Milan Expo 2015, the universal exhibition which will be held in the next few years.
