Cast Iron Metallurgy
Cast iron (CI) is one of the oldest materials in commercial use. It has excellent compressive strength and is commonly used for structures that require this property, as well as for water and sewer lines. This article explains CI metallurgy and why the understanding of this metallurgy is key to understanding other ferrous materials and alloys. The composition of cast iron (CI) varies significan...
متن کاملMechanism of silicon influence on the chill of cast iron
In this work an analytical solution of general validity is used to explain mechanism of the silicon influence on the absolute chill tendency (CT) and chill (w) of cast iron. It is found that CT can be related to nucleation potential of graphite (Nv), growth parameter (μ) of eutectic cells, temperature range (∆Tsc) and the pre-eutectic austenite volume fraction (fγ). It has been shown that silic...
متن کاملGeometrical Optimization of the Cast Iron Bullion Moulds Based on Fracture Mechanics
In this paper, the causes of the crack initiation in cast iron bullion moulds in Meybod Steel Corporation are investigated and then some new geometrical models are presented to replace the current moulds. Finally, among the new presented models and according to the life assessment, the best model is selected and suggested as the replaced one. For this purpose, the three recommended moulds were ...
متن کاملenvironmental effects of gol-e-gohar iron ore mine on groundwater of the area
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Literature search - Deteriorated Graphite Structures on Cast Iron Skins
The fatigue strength offerritic ductile iron, Grade EN-GJS-400-18U-LT. was determined for large section castings measuring 4 by 24 by 24 inches. Fatigue testing was conducted in bending fatigue in order to determine the influence of surface conditions on fatigue strength. Test specimens with various surface conditions were evaluated, including notched and un-notched specimens, as well as those ...
