process for production of compacted graphite iron

spectrum: gray iron with good castability, machinability, damping capacity and thermal conductivity; or, ductile iron with good strength and stiffness. Most decisions required compromise. With the recent advances in electronics, measurement and foundry process control technology, compacted graphite iron has become a viable production material.

Process Insights Why Compacted Graphite Iron? Cutting Developments Make Application Now Practical. In 1949, a now well-known material called ductile iron was patented. At the same time, a lesser-known material called Compacted Graphite Iron (CGI) was also patented, though it was just considered a curiosity at the time.

Compacted graphite iron (CGI), also known as vermicular graphite iron (GJV, VG, JV or GGV from the German: "Gusseisen mit Vermiculargraphit") especially in non-English speaking countries, is a metal which is gaining popularity in applications that require either greater strength, or lower weight than cast iron.. R.D. Schelleng obtained a patent for the production of compacted graphite iron in ...

Compacted Graphite Iron. Compacted graphite iron is an emerging cylinder block material having a higher specific strength than conventional gray iron, and with improved fatigue strength and acoustic properties relative to aluminum, thereby allowing cast iron blocks of reduced thickness and mass to be constructed (Tholl 1996).

A process for producing compacted graphite cast iron thin walled shaped castings in a high productivity line is provided which comprises: (i) forming a near eutectic melt of cast iron, having a low sulfur content, preferably around 0.01% by weight; (ii) adding to the melt sufficient graphite stabilizing agents such as silicon to suppress the carbide eutectic formation at the large undercooling ...

(The company uses "engine equivalents" as a measure for each 50 Kg of compacted graphite iron produced under its license.) After the June drop, the July series production rose to 1.5 million engine equivalents, though Navistar production remained more than 275,000 engine equivalents below its March 2012 level.

Compacted Graphite Iron was first patented at about the same time as ductile iron in the late 1940's. At the time it was viewed more as a curiosity rather than a production material, but its unique properties has led it to be used in many applications which are unsuitable for grey or ductile iron.

Although Compacted Graphite Iron (CGI) was first observed in 1940s, an unstable foundry production precluded its use for high volume production until advanced process control technologies became available [1-3]. Nowadays CGI is used for complex shape …

The compacted graphite shape has been known for some time and also has been called quasiflake, aggregated flake, seminodular and vermicular graphite. Its production is similar to that for ductile iron in requiring close metallurgical control and rare earth element additions, but it also requires another alloying element such as titanium to ...

PRODUCTION OF VERMICULAR GRAPHITE CAST IRON. The invention relates to the production of vermicular graphite cast iron. The term vermicular graphite cast iron is used to denote cast iron in which flake graphite as been modified to a rounded, shorter form compared with the graphite in normal grey cast iron.

siasm of compacted graphite iron (CGI) in recent years. Commercially available for many years and superior to gray iron in mechanical performance, the absence of reliable foundry production had precluded extensive use. With the advent of process control, however, quality castings have become rather routine, spurring high-volume

Jun 02, 1998· The present invention relates to a method for providing pretreated molten iron for casting objects which solidify as compacted graphite iron. Compacted graphite iron, below abbrivated as CGI, is a type of cast iron in which graphite appears in a vermicular form (also referred to as compacted cast iron or vermicular iron) when viewed on a two ...

About us. SinterCast is the world leading supplier of on-line process control technology and know-how for the reliable high-volume production of Compacted Graphite Iron (CGI).

The production of CGI requires careful selection of materials and very close metallurgical control to ensure uniform and consistent compacted graphite structures. This is especially crucial for thin wall sections designed to resist high compression pressures. Properties of Compacted Graphite Iron

A method for continuously providing pretreated molten iron for casting objects which solidify as compacted cast iron, in which inoculating agents are added immediately prior to casting, in exact quantities. In practicing the method, the ability of the fully treated cast iron to crystallize is measured and the result of this measurement is used for feedback control of the supply of inoculating ...
