Raipur, March 4
SAIL-Bhilai Steel Plant’s Steel Melting Shop 3 (SMS 3) has achieved yet another significant landmark when its Basic Oxygen Furnaces No 1 (BOF-1) crossed the lining life of 7000 heats on March 3, 2021.
This feat was achieved in just the second campaign after commissioning of BOF-1. Achieving this landmark in the second campaign of BOF 1 itself is a benchmark in steel industry.
The Basic Oxygen Furnaces (BOF) or Convertors are lined with Magnesia-Carbon bricks. These bricks are subjected to extreme conditions of high temperatures (higher than 1700 degree Celcius) and slag attack. Some areas of the BOF are particularly vulnerable to high erosion during the course of the heat. These areas were closely monitored with the help of the laser profile measurement machine and necessary corrective actions were taken for hot repair of these areas.
It may be noted that production from SMS-3 had started on March 31, 2018 with the lighting up of BOF-1. The production from SMS-3 has been steadily rising after overcoming the initial challenges during ramping up of production and the shop is close to achieving its rated capacity.
