SUMMARY
Factors influencing the production of nodular graphite cast iron in Cairo Foundries of El-Nasr Casting Company were investigated. The applied technique was the injection process, which was done by introducing pure magnesium powder into the melt through a graphite tube using nitrogen as a carrier gas.
Due to the high sulfur content of the produced cast iron during the period of investigation, some trials for desulphurization were carried out, prior to treatment with magnesium. It was shown that better desulphurization can be obtained by increasing the blast temperature of the cupola, or by ladle treatment. The addition of flurospar or increased amount of line stone in cupola charge did not give a sizable effect.
The injection of 4 kg of magnesium powder per one ton of cast iron gave a 100% spheroidal graphite cast iron. The recovery of magnesium that has been obtained was found 27.5% irrespective to the high sulfur content in the base cast iron to be treated.
At the present time it is easier to obtain nodular cast iron as the sulfur content is low.
Basics of Ferrous Metallurgy
Definition:
Metallurgy is the study of
- Mining
- Refining
- Altering the properties & preparing for use
From the all known metals we are going to discuss changing the properties of:
Gray iron & Steel: In chemical terms, steels has carbon content from 0.05% to 1.70% while Gray iron has carbon from 1.7% to 4.0% .

The high consumption of Ingot Molds and the cracking of Cast Iron Pipes urge the Egyptian foundries to produce them from nodular cast iron. Ingot Molds made from this cast iron lasts 2:2.5 longer than that of gray cast iron (Ref. 1).

Heavy Machinery Systems Design and Operation
Program Overview:
The use of Heavy Machinery is growing day after a day in the petroleum, construction, mining, quarry and road building industries worldwide especially in our Middle East countries to rebuild or update the existing infrastructure. Engineers who don’t have a solid understanding about different systems operation, testing, adjusting and maintaining heavy machineries will not have a good career opportunity in the future.
