Abstract

The present invention relates to cast iron, and more specifically relates to CGI (Compacted Graphite Iron) cast iron in which the amounts of carbon (C), silicon (Si), manganese (Mn), copper (Cu), tin (Sn) and magnesium (Mg) are controlled during production, thereby improving the castability and also giving a stable tensile strength and yield strength and giving an appropriate range of hardness, and also to a production method for the same.

Description

technical field [0001] The present invention relates to cast iron and its manufacturing method, and more specifically, to cast iron having improved castability and stable tensile strength and yield strength by controlling the content of ingredients added to iron, and its manufacturing method. The cast iron according to the present invention belongs to hypereutectic CGI (compacted graphite iron: compacted graphite iron) cast iron which is particularly suitable for a cylinder block of a high output diesel engine. Background technique [0002] In recent years, since environmental regulations have been strengthened, it is inevitable to reduce the content of environmental pollutants such as Cox or NOx discharged from engines. [0003] In the case of a diesel engine, in order to reduce the emission of the above-mentioned environmental pollutants such as Cox or NOx, it is necessary to increase the explosion pressure of the engine. Thus, in order to increase the explosion pressure ...
