Filling And Solidification

The casting process design of large cast steel supports is carried out, and the special integrated sand core and forged steel cast lugs are used to simplify the cavity manufacturing process. The ProCAST software was used to simulate the casting process of the stent, simulating the filling and solidification of the casting, and predicting the occurrence of defects such as shrinkage and shrinkage of the casting. According to the simulation results, the cause of the defects is analyzed, and the casting process of the stent is optimized. The simulation results show that the optimization scheme effectively reduces the casting defects and the surface of the stent is free from defects.

Abstract In this study, the process design, development and mechanical analysis of Cu-Zn alloy produced by sand casting process were carried out. The process parameter optimization was carried out using the Response Surface Methodology (RSM) with the process conditions in the following range: temperature (300-500oC) and zinc content (5-25%) having the hardness and ultimate tensile strength as the response of the designed experiment. The raw materials were scraps of copper wire and zinc battery casing and 13 different compositions of the alloy were prepared having the total mass for each weight percentage weighing 1.5 kg. The results obtained indicated that the hardness and ultimate tensile strength increases with an increases in the zinc content but decreases with an increase in the temperature. The elongation was however found to increase with an in increase in temperature but with a decrease in the zinc content. It is envisaged that the findings of this work will assist the brass material developers and the end users in the development of products with excellent mechanical properties.

This paper presents the study to investigate the effects of binder ratio, in-gate length and pouring height on hardness, surface roughness and casting defects of sand casting process. Taguchi methodology with L9 orthogonal array was employed to design the experimentation. Sand casting of six blade impeller using A356 alloy was performed and empirical models for all the above response measures were formulated. Confirmatory tests and analysis of variance results confirmed the accuracy of the model. Binder ratio was found to be the most significant parameter affecting casting surface defects and surface roughness. This was followed by pouring height and in-gate length.

In this article, the authors use of Si, Mn, Cr as the main alloying element, developed a tough wear resistant cast 35CrMnSiMo, after casting, to obtain a wear-resistant cast steel with a hardness and impact toughness mechanical performance testing, metallurgical microscope and scanning electron microscope analysis of the microstructure. The results show that, the cast 35CrMnSiMo 850 °C austenitizing insulation 30min and then quenched, the material water hardened degrees is much larger than the oil hardened degrees. The the water hardened than oil hardened degrees up 28.5%. Metallographic photo clearly see a lot of lath martensite, the small amount of lath martensite and retained austenite, the oil quenching microstructure edge outline is somewhat vague, while clear the water quenching microstructure edge contour darker, impact toughness with hardness is inversely proportional to the sample.
