1.What inspection functions are performed for the detection of casting cracks, porosity, and shrinks?
3.Objective:Investigate the therapy effect of budesonide aerosol in treating asthma.
4.Neck Shrinkage Control of Composite Rollers with Nodular Iron as Core Material
5.Abolish the shrink-looseness shortage of conjunctive plates cast of shearer roller
6.Dispersed shrinkage is the main reason causing leakage of multi-cylinder heads of diesel engines.
7.This article is written to explain how to improve the efficiency of riser feeding for cast steel items by modular design method,and the quality of cast steel items is approved when Mw?M 件 and ε(V 冒+V 件)? V r·η ,on shrinkage hole and porosity if this method is used
8.Based on the simulation program and the shrinkage hole index and the shrinkage prosity,it is possible to predict the casting quality of the rim and to find out the optimum programming parameters, therefore the lead rate of rim an be reduced,the casting quality of rim can be improved and the cost of production can be lowered.
9.The solidification simulation for HSi80-3 silicon brass rudder bonnet by the Procast software has been conducted based on two kinds of gating systems to investigate the potential shrinkage hole (porosity) position in the castings.
10.Abstract: Using furan sand to produce heavy diesel engine block and crankshaft eliminated defects of castings including “penetration/burn-in”,“shrinkage porosity”,“big dimension deviation” of cylinder block,“penetration/bum-in”,“misrun”and“run-out”of crankshaft,and so on.
