Slab Casting
There are two "1+1" 120 tons melting and casting production line and a "2+1" 90 ton melting and casting production line. Melting and holding furnace group design for the Otto Juncker company, the hydraulic tilting type gas heating furnace manufacturing Suzhou new light. The foundry machines all adopt the latest semi - continuous low level vertical shaft casting technology of WAGSTAFF in the United States. ABB is equipped with electromagnetic stirring, on-line hydrogen measurement and on-line slag measurement system. The online treatment of aluminum melt is based on French NOVELIS online degassing system and deep bed filtration system. Japan's Mitsui metal plate filtration and tubular filtration, the efficiency of degassing is 0.12ml/100g-AL, and the filtration efficiency is above 98% (10 m below impurities).
It can produce 1, 3, 5, 6, 8 series and other alloy ingots. The product specifications cover all the main specifications of the country, the smallest product is 520mm * 1000mm * 9150mm, the largest product is 640mm * 2410mm * 9150mm, the largest ingot weight is up to 37.5 tons.
Cleanliness measurement On-line hydrogen measurement by ABB-AISCAN
Our use of France's Novelis Alpur three rotor three heaters online degassing system, capable of chlorine and argon, and the hydrogen removal efficiency can reach above 70%, deep drawing materials, aluminum billet, material tank hydrogen content can be controlled under 0.12ml/100gAl, the tank cover, pull ring material can be controlled under 0.14 ml/100gAl.

slagging-off Machine STAS powder refining
Furnace refining equipment is rotary jet spray RFGI graphite rotor Canada STAS company design and production of refining equipment, high refining efficiency, degassing and slag refining effect, 40-50min can effectively remove most of the hydrogen in aluminum melt and slag, meet the high-end products in addition to hydrogen slag, aluminum and hydrogen content control in 0.30 the following ml/100g-Al.
The on-line filtration is the matching of plate filter and imported tube filter for Japan's Mitsui. The plate type filter for coarse filtration, the main role is to prolong the service life of the equipment behind the import filter, install 50PPI filter plate, can filter out more than 20 mu m impurities, filtration efficiency is 100%; the fine filter (tube type filter) can generally be impurity particles of more than 5 m by the vast majority of filter, filtration efficiency more than 95%.
Japanese Mitsui Corp tube filter system
Novelis deep bed filtration system
Casting system using Wagstaff casting system, strong stability, high safety coefficient, low level of LHCTM ingot casting process and the combination of the lubricating oil using only traditional direct condensation casting consumption of 3-5%, and the graphite cavity can be replaced, which greatly extend the life of crystal end. In the LHC production process of ingot, have minimal warpage and a small ingot shell, can obtain the milling surface quality and surface less yield can reach more than 97%.

Sermas, a double headed sawing machine, which can be sawed at the same time at the same time, with a maximum speed of 10 blocks per hour. The milling machine is the most advanced model of Japanese Kobelco with high precision and high rigidity. The milling machine and sawing machine are arranged in a series way. After the aluminum slab is sawing the head and tail, it is transported directly to the #1 milling machine through the roller table to finish the milling on the top and side. After turning over automatically, the #2 milling machine will finish the milling of the other side, which greatly improves the efficiency of sawing and milling.
