Analyzing and simulating of the deformation law of the ceramic downspout product after overcoming the shortage of powder material models in the software of MSC. MARC. It shows out the important effects of various factors and the shape of mandril during the process. And it is obvious that the shape of the top mandril has more effects on the process than the bottom.(3) Showing out the important effects of model figure on the flowing of powder and the forming of low-density fields from the analysis. After changing the top of the mandril into spherical shape, an improving model is putting out so that the distribution of stress and strain turns to be even and proper and that the flow rule of powder grains is better.(4) Calculating of the dimensional precision and the cutting ratio of the product and analyzing of the effects of such factors as rubber aging, loading process, mandril, friction etc. on the cutting ratio.

Co-firing characteristics of corn stalk and stone coal in different proportion were investigated by thermal gravimetric analysis. The results showed that corn stalk can improve the ignition and combustion of stone coal. The agglomeration experiments on corn stalk were made in a bench-scale bubbling fluidized bed with quartz sand as bed material and stone coal ash as additive. The results indicate that stone coal ash can inhibit agglomeration of bed material particles at temperature of 900℃. Agglomerate of blends was analyzed by means of scanning electron microscopy, energy-dispersive X-ray, and the bed materials were analyzed by means of X-ray fluorescence. Analysis showed that aluminum element and iron element in stone coal ash can react with alkali compounds and eutectics with low melting point, form a covering layer with high melting point on the surface of biomass and quart sand particles, thus inhibit the forming and transfer of low melting compounds.
