Atomization and condensation of rare earth alloy
Into EqNi particles (typical diameter of l50 ~ 250ran) in a modern Gifford McMahon (Gifford-Mcmahon, G-M) low-temperature-induced carry sealed bed heat exchanger or regenerator applications. The use of Er ~ 'qi direct replacement shot to make Yun gas heat exchanger medium speed upstream. G-M cooling device is cooled with the selected low-temperature superconducting devices such as magnetic resonance imaging and high-speed electronic switching circuit, their operating temperature of about 4K. In the Curie temperature (Tc) occur within the material under an order disorder transition,
ghd planchas, resulting in heat capacity anomalies, which makes Er, Ni become a valuable precious materials. Tc by Shejin composition and crystal structure of the control of impurities affect the heat capacity peak height and width, oxygen, carbon and nitrogen ask gap doping elements can damage the magnetic ordering. With a similar situation is LaNi, Ef ingot casting process will lead to macro-segregation, have long heard of the untidy by the fire to eliminate it. The annealed ingot broken into polygonal powder. Compared with the spherical powder, powder selection with l9 ·:, {go, j greater tendency from the dust and debris. Although in general is used to produce the powder diameter is less than 75/a11, but Er3Ni of HPGA also can be used as carefully studied the rapid cooling of this alloy powder and the first step in direct production. As the gas atomization mechanism, the desired size range of powder is often hollow, and the doping agent is the entity. Proved, as the direct production of powder technology, spin production and equipment £ .... ... ... J turn disc spray is a viable industry. Japan's Toshiba Corp. has sold in the international market EqNi spherical powder. In further studies, the successful development of CAfRQB liquid quenching process, which uses liquid silicone vacuum as quenching medium. Condensation of liquid quenching powder significantly different from the organizational gas quenching powder microstructure. (Huang Jinchang) Ukraine titanium sponge production plant equipment, technical innovation ÷ bud '- Ukraine joint investigation Bo Luoshi Titanium Magnesium is the world's first production of titanium sponge factory, founded in 1954. March 1954, the Soviet Council of Ministers adopted a resolution on measures to develop the production of titanium, provides for 波多尔斯克 chemical metallurgical plant design basis and to carry out the necessary adjustments, re-use other companies ready-made design of some plant program, check the crossing in Rosh City building a factory. China and the Soviet Union was building a similar plant with investment experience. In February 1954, just before crossing the Duoersike chemical metallurgical plant began producing a small amount of titanium, only verify some of the main process specifications. Plant design is unconventional approach: the grass with the preparation of comprehensive design plan, there is a complete investment process, only a partial number of building design, construction of main production plant on the rush to plant floc structure, and then process process has been arranged to cover the plant in. Accompany gold in 波多尔斯克 chemical production plant experiments exposed a series of process and equipment problems,
tory burch outlet, have not been satisfactorily resolved. After examination of the lack of raw data,
tory burch outlet, increasing the plant design and construction difficulties: many drawings had to draw some plant and facilities to be demolished for redevelopment. However, the main task is to be completed within in a short question: the factory in August 1954 the first plant began pouring the foundation, the main workshop in June 1956 production, June 29, 1956 the system of the first block of titanium sponge. Production of almost 40 years ago after many of the modernized plant, the production of titanium sponge boat force expanded by 30 times, mastered the use of closed submerged arc furnace production of titanium slag, the molten slag chlorinators in the carbonation of thorium chloride oriented, with no magnesium diaphragm cell electrolysis process raw materials and other advanced methods. And the foam separation of thorium and restore process is complete work for very little. The company's titanium production plant are in the first few years of industrial development phase of the construction of the old plant, as production capacity continues to expand, resulting in the following main issues: the main process equipment cycle of low productivity, do not ship to ensure product quality, labor consumed in large quantities, poor production conditions. To the late 1980s, the same type in the former Soviet Union among producers of titanium sponge, the company's economic and technical indicators are the worst. However, in the Soviet era, this situation is not caused to the company's sales problem, almost all of the sponge thorium are sent to the Ukrainian foreign,
p90x workout schedule, mainly to Russia and used in the military industrial sector. The loss in production of titanium sponge production of other products are of high profits to cover. In recent years, the Soviet Union and the economic transition, decreased demand for thorium. In addition, check the titanium magnesium crossing Roche Zhicijiagao combined company's products, there is no competition in the market
