1 alloy blade of double-shaft mixer national patent number: ZL0 1279 135.0.
The alloy blades of double-shaft mixer are made of special YT 15. After cemented carbide is fixed in the model, it is produced with special molten steel and molybdenum metal materials. Cemented carbide has high strength and wear resistance, and the hardness of base metal HRC is greater than 55, which is three times higher than that of brazing alloy. The size of the blade can be provided according to the size provided by the manufacturer.
2 spherical disc edge scraper and unpowered edge scraper
Covered electrode J422 is used as the edge scraper for granulation, which is welded on the blade of scraper without any treatment, but it takes about one and a half years.
Unpowered scraper is used for the worn part of unpowered bottom scraper, and it is welded into the groove of the substrate by copper, which is more durable.
2 1 century is a historic opportunity for the Chinese nation to achieve all-round rejuvenation and take off in the world. With the great situation of China's accession to the World Trade Organization, the field of building materials science and technology in China is unprecedentedly active, the equipment of cement plants is constantly updated, and the manufacturers show their magical powers. Scientists and technicians have developed new alloy blades with their own characteristics.
