✦ Synopsis
This forms a mixture of the pre-ceramic polymer and interface materialcoated reinforcing fibres. moulding an exhaust manifold-shaped structure from the mixture by placing the mixture on at least a portion of the castahle material, and firing the structure. The manifolds produced are resistant to erosion, minor impacts, and thermal shock. 97103147 Melting mechanism of gunning mixture particles along axis of coal-oxygen flame Wang. X. and Li, H. Gangtie, 1996, 31, (S), 21-24. 56. (In Chinese) In order to study the effect of gunning distance and particle size on the melting of refractory particles, a temperature model was developed. The model is useful for selection of gunning distance and particle size for the repair of refractory brick wall in metal smelting furnaces. 97103148 Refractories for the lining of large synthetic ammonia installations Hu, B. Naihuo Cailiao, 1996, 30, (4) 234-238. (In Chinese) The refractories used in lining of large synthetic ammonia installations are discussed. The topics include the technical principle, choice of furnace type and lining refractories of large synthetic ammonia installations imported from abroad using natural gas, residual oil and coal as raw materials and the progress of home-made refractories for gasifiers and their wear mechanism.
