Basic Pig Iron used mainly in electric ARC steel making.
Foundary Pig Iron used in mainly in the manufacture of grey iron casting in cupola furnaces.
Pig iron is produced from the blast furnace. The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called ‘hot metal’. The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron. These liquid products are drained from the furnace at regular intervals. The hot air that was blown into the bottom of the furnace ascends to the top in 6 to 8 seconds after going through numerous chemical reactions. Once a blast furnace is started, it will continuously run for four to ten years with only short stops to perform planned maintenance. Pig iron is an intermediate product and first product of Iron making reduced from Iron ore. Pig iron has a very high carbon content, typically 3.5–4.5%, along with Silica, Manganese, Sulphur, Phosphorus and other trace elements.
Pig iron is used for steel making, foundries, alloy making, in automotive castings and other iron based castings.
Pig Iron comprises three main types:
BASIC PIG IRON (BG GRADE) which used mainly in electric arc steelmaking,
FOUNDRY PIG IRON (FG GRADE) used in mainly in the manufacture of grey iron castings in cupola furnaces.
NODULAR PIG IRON (SG GRADE) used in the manufacture of ductile iron castings.
We produce compositions within fairly narrow ranges of specifications with the objective of optimizing customer's costs due to non‐addition of additives, standardization of process parameters and minimization of rejects. We are long‐term suppliers to some of the global brands & OEMs from automobile industry and some of the most reputed steel mills and foundries.
Given below are the indicative specification of our pig iron grades which we supply to our valued customers primarily in India and also in Middle‐East, Far‐East, South–East Asia:
