According to the Finnish news: On February 29th, Outotec, the world leader in minerals and metal processing industry, won several orders for aluminum technology related to large-scale expansion or process transformation from China's aluminum smelter. The total value of these orders is about 17 million euros.
According to reports, these orders include:
A set of large ingot casting system with a rated capacity of 30 tons per hour and a remelted aluminum ingot (large ingot) with an ingot weight of 700 kilograms. The reform system was provided to Huojun Hongjun Aluminum Power Company located in Inner Mongolia Autonomous Region. Outotec's equipment delivery time is 9 months;
A set of 30 tons per hour 700 kilograms large square ingot casting system and two sets of major anode assembly process equipment for the new aluminum processing project of the Yellow River upstream hydropower development company in Xining City, Qinghai Province. Production of the project is expected to begin in March 2009;
A vibration molding machine and a set of main anode assembly process equipment were used for the expansion of Chinalco Fushun Aluminum Company located in Fushun City, Liaoning Province. The vibration molding machine will be delivered in Germany in November 2008, while the anode assembly equipment is due for delivery in August 2008.
“China is the largest primary aluminum producer in the world. China's electrolytic aluminum plants continue to expand new production capacity to meet strong market demand. These orders prove that our advanced aluminum technologies and services can meet the needs of our Chinese customers.†According to Tapani Jarvinen, President of Outotec.
Vitrified Grinding Wheels mean grinding wheels in ceramic bonded. Vitrified grinding wheels can be superabrasive grinding wheels like diamond grinding wheel or CBN Grinding Wheels. It also can be abrasive grinding wheels such as white aluminum oxide grinding wheel,pink grinding wheel,silicon carbide grinding.
Vitrified grinding wheel is only one type of bond, which is ceramic, it can be in any type of abrasive.
The main ingredient of vitrified bond are vitreous material with low melting point, such as borosilicate glass, lead glass, etc.It is widely used in various grinding methods such as outer circle, inner circle, flat surface, centerless, etc. It is the most commonly used bonding agent for abrasive tools.
Vitrified bond is characterized by high chemical stability, almost can work in a variety of cooling media, small elastic deformation, brittle, can be made into a variety of hardness levels of grinding tools to adapt to the processing of various hardness of the workpiece. Vitrified bond has good self-sharpening.
The grinding efficiency of single crystal diamond with vitrified bond grinding wheel is higher than metal bond grinding wheel. The wear ratio is very small and the processing cost is low. Therefore, the grinding efficiency of single crystal diamond with ceramic bond grinding wheel can be greatly improved.
