GT is a "source of power" of modern manufacturing, audi a6 quattro turbocharger in which high-temperature turbine blades is one of the core components of the gas turbine. GT is one of the main power source for large passenger aircraft, ships and civilian power generation and other specialty areas, and high-temperature turbine blades and turbine manufacturing technology is the core, and it is a major bottleneck restricting the development of the gas turbine. Foreign this strictly confidential, so that our major projects large aircraft, ground gas turbine, etc. are controlled by others objectively. 2008 establishment of the Shanghai Municipal Science and Technology Commission special issue of major research, technical studies and research for the current world's most advanced F-class heavy-duty gas turbine 256MW turbine blade temperature, dominated by the Shanghai University of commitment. Manufacturing principles turbine blades, vw passat 1.8 turbocharger is a nickel-based metal solution casting in a mold, and then cooling and crystallization, a process similar to the winter cold vapor on windows crystal formation, "Ice." Turbine blades can withstand high temperatures, whether there is a sufficient number of strength, and the temperature during the crystallization and the crystals formed have a relationship or orientation. The technology is currently the most difficult in the industry, is to make the entire blade into a grain, or "crystal" technology. In addition, if the grain so that orderly arranged in one direction, but also can improve the strength of the blade, to avoid breakage, such techniques as "directed" technique. Through four years of effort, the research group on the path of the two technologies are a breakthrough, formed its own unique process route. The success of this project will not only help our country to break the blockade of foreign aspects of the key components in a gas turbine, for domestic power plants is also great news. Heavy-duty gas turbine to turbine level, for example, a total of 96 superalloy blades, if the use of foreign manufacturers of products, the manufacturing cost of a blade at about 400,000 yuan, the market price of 100 yuan; but if the use of domestic leaf manufacturing cost is only 1/4 of foreign prices.Related Articles:http://turbo.dosugoi.net/e698775.htmlhttp://turbo.naganoblog.jp/e1595984.html
