Effect of pouring temperature on the Lost Foam Process
Journal Title: Archiwum Odlewnictwa - Year 2011, Vol 11, Issue 3
Abstract
In this study, the analysis of the influence of the pouring temperature on manufacture process of castings by the Lost Foam method was introduced. In particular, numerical simulation results of effect of silumin and grey cast iron pouring temperature on pouring rate and gas gap pressure were analyzed. For simulating investigations of the Lost Foam process introduced mathematical model of the process was used. For calculations, the author's own algorithm was applied. The investigations have proved that with increasing pouring temperature the pouring rate increases, while pressure in the gas gap are decreasing. The author’s own investigations showed a more significant effect of the silumin pouring temperature than grey cast iron pouring temperature on the lost foam process.

Modern precise high-power water-cooling systems for press quenching
Demand for extrusions in transport applications is increasing rapidly. The extrusions must be strong, light, crashworthy and may have to undergo hydroforming. This implies low wall thicknesses (1-2½ mm) in strong alloys...
Application of calorimetry in evaluation of phase transformations in the selected hypoeutectic silumins
The investigations of phase transformations described in this study were carried out on hypoeutectic alloys from the Al-Si during heating and cooling. The determination and analysis of characteristic temperature values f...
Analysis of the Inconel 600 alloy destruction process in the surrounding of oxygen, nitrogen and hydrogen
This paper presents results of research, which was targeted to define reasons of the short life of sieves made from a 0.8mm diameter wire of the INCONEL 600 alloy. It was noticed that when the sieves were used in the dev...
Plastic properties of cold-deformed ironbased sintered materials
Cold plastic forming of sintered metal powders has limited practical application because of, among others, the deformation degree and initial porosity of preforms. Cold forming is combined with a very drastic drop of pla...
