An SG iron foundry, in simple terms, refers to a factory where iron casting production takes place. In order to create iron, foundry workers pour molten material into a mold with a hollow interior and allow it to cool and solidify.
The hollow interior determines the shape of the casting. The casting is the name given to the component that has solidified. Here is more information about how SG iron foundries work producing SG iron and its applications.
How does an SG iron foundry work?
Foundry workers shape metals by melting them into a liquid, pouring them into a mold, and then removing the mold material once the metal sets and cools.
Steps followed in a foundry when making SG iron.
SG iron foundry in India are well known for making this specific type of iron. Making ferritic spheroidal graphite iron involves charging an electric furnace with steel scrap and graphite. The graphite weight should be about 3% of the weight of the scrap.
The furnace melts the steel scrap and graphite with the electric power on. When the melt reaches a temperature not exceeding 1400° C, the worker turns off the furnace and deslagges the melt. Next, add enough ferrosilicon to achieve the desired silicon content of the melt.
Similarly, add enough graphite to raise the melt’s carbon content to the required level. The melt is then superheated to a temperature between 1454° and 1537° C and deslagged once more. Finally, the foundry worker corrects the metal analysis and then inoculates the metal out of the furnace.
Uses of SG Iron
SG Iron has several uses:
Pipes and Fittings for Pressure
SG Iron is a suitable material to sustain the high working pressures encountered by pressure pipes and fittings due to its outstanding strength-to-weight ratio and toughness.
Applications in Agriculture, Roads, and Construction
SG Iron is frequently used in agriculture for various purposes, including tractor parts, compressors, brackets, clamps, and pulleys.
Applications of Engineering in General
SG Iron’s strong tensile and yield strengths make it the ideal metal for use in various hand tools, including wrenches, clamps, and gauges.
SG Iron has shown to be a reliable, less expensive alternative to steel forgings, steel fabrications, and malleable iron castings. They accomplish this by combining alloy additions and heat treatment.
