Iron Casting and Energy conservation an interesting walkthrough

Iron Castings generally refers to grey iron castings and spheroidal graphite cast iron castings. Cast iron is manufactured easily; hence the cost of manufacturing is much lower. Apart from that it has different physical and chemical properties that render the flexibility to be used across industries, such as the automobile and other mechanical industry.

Across the globe around 50 tons of cast iron is produced annually. The process of gray iron castings are resistant to abrasion and corrosion, have good casting ability, machine compatibleand are the highest amount of products are delivered to different industries from grey iron casting alone. Approximately three fourth of all castings products of metal are done by iron casting.

As the volume of production varies, the amount of energy consumed also fluctuates. The evaluation standard for total energy consumption is kcal per ton.

In the melting process of cast iron energy conservation needs the following steps to be taken seriously;

• Reducing heat loss
• Minimizing heat input
• Improving melting operations

Conservation of energy is the cupola is equally significant for the iron castings process.
The spheroidal graphite cast iron is of higher quality than grey cast iron, as per its mechanical properties like ductility. The production of this casting iron has taken multi-fold, all because of the extensive use and demand from across leading industries.

Around 50-90% of the total energy consumption in iron casting is done during the heat treatment and melting process. It is wise to keep a record of the total energy consumption in an iron casting foundry, otherwise it would be impossible to keep a tab on the energy consumption and ensure energy conservation.
