PSA nitrogen generator system in the Federal Republic of Germany introduced the application of sintering furnace

7ppm. Use the product dubbed the N + H2 gas protective atmosphere, the sintering conditions and the hardness of the steam treatment unit using the decomposition of ammonia were higher than those for the protection of the atmosphere. Key words: PSA nitrogen generator nitrogen purification device by the UN system to help Germany MWV company introduced the conveyor belt sintering furnace with ammonia hydrogen gas mixture for the protection of the atmosphere, PSA ammonia system to provide high purity ammonia. The ammonia system is based zeolite as adsorbent, the use of pressure swing adsorption, at room temperature, low pressure conditions, taken directly from the air in the system ammonia. Preparation by the ammonia zeolite, outlet pressure 0.4-0.5MPa, the dew point is a 35 ℃, a purity of 99.5 purification device is the use of ammonia mixed with a small amount of hydrogen catalytic tower backward people, heated to 100 ~ C or so, when his bed through the palladium catalyst, hydrogen and nitrogen react with residual oxygen. After cooling, after cooling, the gas-water separator to remove condensate, and finally drying by the dryer temperature,[link widoczny dla zalogowanych], static and bear to the high-purity ammonia gas, the outlet pressure 0.45-0.5MPa, the dew point is a 60 ℃, the purity 99.9995%. Ammonia System PSA process shown in Figure 1. PSA ammonia system has been used in our plant, the gas analysis, the flow pressure and oxygen content, dew point and other technical means prince Yu 1PSA La nitrogen system flow marked circle 1tt8 powder metallurgy technology Vo1.8 meet the requirement. One day, PSA nitrogen system uses two sets of records during the summary shown in Table l. I ~ eC sintered materials, and to do with the decomposition of ammonia gas 1 Bong protection compared to the hardness of the sintered parts and steam treatment, the hardness values were increased in the carbon content and stable,[link widoczny dla zalogowanych], as shown in Table 2. PSA nitrogen generator system with a system of high purity ammonia, low investment, easy operation,[link widoczny dla zalogowanych], starting 1 hour after the operation, stability can pass gas.

O Machinery Metallurgy Science and Technology Information Network of the first Wangyuan Assembly held in Laiwu, Shandong Machinery Industry powder metallurgy Ang Wang Yuan Science and Technology Information Network of the first General Assembly on 8 June 1990 was held in Shandong Laiwu. Participate in the National Assembly boast a total of 71 powder from enterprises (thing) industry on behalf of 99 units. Information network net long powder metallurgy,[link widoczny dla zalogowanych], Beijing Institute of Powder Metallurgy, vice chair of the steep and Comrade Lin Zengdong opening statement. Department of Electrical and Mechanical Products Division Gong Mingji based chief engineer, electrical machinery industry by the Ministry of Information Industry Director SONG Ji, Zhou Kaili Powder Metallurgical Association president Ang would like to congratulate and wait for an important speech. At the meeting summed up the intelligence network to work more than a year to develop the work plan for 1990 identified the intelligence network stumble L boast after development. Professor Han Fenglin ashamed, entitled \ Conference papers also carried out exchanges of information, 11 Congress preach the papers and selected the work of 24 intelligence network activists . It is agreed that to promote democracy and solidarity, the spirit of mutual assistance for the industry to contribute more. (Zhao Ge feed) a
