In the introduction section, the authors discuss the methods of producing Al-graphite Composite by adding nickelplated graphite in liquid aluminium. As compared with these conventional liquid-mixing methods, the rheocast method has the following advantages: 1) there is no need of nickel plating for the graphite powder, 2) greater amount ofgraphite can be mixed in the melt: 3) better casting quality and longer mold life, In the first part of this paper, the rheocast method and its equipment is Described....

In the introduction section, the authors discuss the methods of producing Al-graphite Composite by adding nickelplated graphite in liquid aluminium. As compared with these conventional liquid-mixing methods, the rheocast method has the following advantages: 1) there is no need of nickel plating for the graphite powder, 2) greater amount ofgraphite can be mixed in the melt: 3) better casting quality and longer mold life, In the first part of this paper, the rheocast method and its equipment is Described. It is shown that the best stirring condition is a melt with 40-60% solid phase. A method for accurate controlling this apt proportion of solid phase in the melt is proposed. Experiments shown that this simple timecon- -trolling method is workable, Stirring is done under vacuum condition. The optimum stirring speed is 1800 r,p.m,for 10 min. In the second part of this paper, the production of Al-Si 8%-graphite 6% composite is discussed. Tests shown that a composite with an even distribu- tion of graphite can be obtained With a graphite content up to 20% by wt. Spectral pure graphite powder is used, 70% of the grains are within the range of 0.1-0.3mm , The powder is evenly spread over the surface of the melt. The bearing quality of this composite material is tested with a composite sleeve running against a steel shaft with a load of 6 kg/cm2, at a linear speed of 1.2m/sec for 14 hrs under lubricating condition. Wear out for the composite is 0.020g, which is about 20 times better than that of Al-Si 8% alloy(0.391g). The wearability and coefficient friction of this Al-graphite composite is 0. 020g and 0.009 respectively, which is comparable with ZQSn 6-6-3 bronze (0. 021, 0,009). Tests also shown that the Al-graphite composite has very good damping capacity, which is comparable with gray cast iron. Owing to its lightness, its damping rate/density ratio is many times higher than that of gray cast iron.

SS920 stainless steel exhibits a good corrosion resistance to high temperature concentrated H2SO4 by forming a layer of steady passvating film on the metal surface. Its corrosion rates in 93% H2SO4 were <0.01mm/a at 100℃ and < 0.035mm/a at 130℃. It has similar mechanical properties to 904L and 316L stainless steel and is easy to be cast and worked, SS920 steel shaft sleeve was used in Guixi Smelter and worked satisfactorily.

A 240m chimney with exterior R. C. shaft and interior doublesteel shaft has been well con- structed by the bydraulic self-climbing and reversible lifting method. The whole construction work has been finished completely within 58 days. And its No. 1 interior steel shaft's lifting work has been done with high speed efficiency. Besides, it is to be noted that the shaft's central deviation is merely +3. 47ram, while its relative slant deviation is only 1/6900. Therefore, it is generallyrecognized as a high quality job and up to the standard of international level.
