Achievement report for fiscal 1981 on Sunshine Program-assisted project. Research and development of materials for coal liquefaction plant (Research on materials); 1981 nendo sekitan ekika plant zairyo no kenkyu kaihatsu (zairyo no kenkyu) seika hokokusho

Abstract

Research and development is started of materials for constituting a liquefaction reactor which is the primary apparatus in the coal liquefaction process. Tested in the basic research on the designing of alloys for the reactor are Cr-Mo-V-Ti based alloys prepared by adding V, Ti, and B to Cr-Mo based alloys presently in use as materials for pressure vessels. They are melted and 50kg test ingots of steel are prepared, and an alloy with a constitution of Low Si-3%Cr-1%Mo-0.25%V-0.02%Ti-0.002%B is selected. In the designing of alloys to serve as stainless steel overlay welding materials and in the development of basic welding technologies, studies are conducted in search for materials that exhibit excellent durability under the conditions of liquefaction reaction and for technologies in this connection. These are accomplished using a test device installed this fiscal year, which is capable of reproducing high-temperature high-pressure hydrogen atmosphere. As the result, basic technologies are acquired, which will enable the achievement of the goal. In the study of on-site production technologies using medium-size ingots as the materials, an 85-ton medium size steel ingot of a new chemical constitution of Low Si-3Cr-1Mo-1/4V-Ti-B is melted, and a shell which is 400mm in thickness and 2m in internal  More>>
