Effect of thickness of refractory coating on the Lost Foam Process
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 3
Abstract
The analysis of the influence of the thickness of refractory coating on the production process of casts in the Lost Foam process was introduced in the work. It was conducted in the peculiarity the analysis simulating investigations the influence the coating thickness on the pouring rate, pressure in the gas gap and gas gap size. For simulation tests of the Lost Foam process, a mathematical model presented in this study was used. For calculations, the author's own algorithm was applied. Investigations have proved that with increasing thickness of coating the pouring rate decreases, while pressure in the gas gap and the size of the gap are increasing. The author’s own investigations have proved a very significant effect of the coating thickness on the Lost Foam process, and specially on the mould pouring rate.

Mechanism of carbon influence on the transition from graphite to cementite eutectic in cast iron
In this work an analytical solution is used to explain mechanism of carbon influence on the transition from graphite to cementite eutectic in cast iron. It is found that this transition can be related to (1) the nucleati...
