This document provides an overview of a vocational training session at Bhilai Steel Plant in India. It first provides context about Steel Authority of India Limited (SAIL) being the largest steel maker in India. It then describes the introduction and history of Bhilai Steel Plant, including its production capacity and source of raw materials. The document outlines the departments visited during the training, including the Main Step-down Distribution System (MSDS), Electrical Repairing Shop (ERS), Steel Melting Shop (SMS), and Blast Furnace 8. It provides photos and descriptions of the layout, equipment, and processes at each location.

1959 by the president of India Dr. Rajendra Prasad with a production
capacity of 1.0 million tone.
 The captive mines of the plant located at Dalli-Rajahara supplies iron ore
complex,80 kms from bhilai and lime stone used to be available from
Nandini captive mines, 23 kms from bhilai.
 Niine times winner of Prime Minister’s trophy for best integrated Steel
Plant in Country.

18. BLAST FURNACE-8 (MAHAMAYA)
 The purpose of a blast furnace is to chemically reduce and
physically convert iron oxides into liquid iron called “ hot metal “ .
 Hot metal is used to steel melting shops(SMS).
 BF Works:- The hot air blast to the furnace burns the coke and
maintains the very high temperatures that are needed to reduce
the ore to iron. The reaction between air and the fuel generates
carbon monoxide. This gas reduces the iron oxide in the ore to
iron.
iron oxide + carbon monoxide = iron + carbon dioxide
 Limestone is added to the blast furnace to capture impurities and
create a waste slag.
 Mahamaya useful volume of 4060 cubic meter and capacity of
producing 8030 tone of hot metal per day or 2.8 million tone per
annum.

24. Steel Melting Shop-1(SMS-1)
 Hot metal received from blast furnace. Is
converted to steel by removing carbon and other
elements present. A analysis of metal received
from blast furnace is :-
 C - 3.5-4.0 %
 Si - 0.6-1.0 %
 Mn - 0.6-1.0 %
 S - 0.05 % max
 P - 0.10 % max
