Bhilai Steel Plant Sets Record for Converter Lining Life

12/02/2010 - Bhilai Steel Plant of Steel Authority of India Ltd. (SAIL) has set a national benchmark with Converter ‘C’ in its Steel Melting Shop-II recording 12,325 heats in lining life before it was taken down for relining. The plant broke its own previous national record for top-blown converters of 11,036 heats achieved by Converter ‘B’.

Bhilai Steel Plant (BSP) of Steel Authority of India Ltd. (SAIL) has set a national benchmark with Converter ‘C’ in its Steel Melting Shop-II recording 12,325 heats in lining life before it was taken down for relining. BSP broke its own previous national record for top-blown converters of 11,036 heats achieved by Converter ‘B’.
 
BSP’s Converter Shop in SMS-II produces crude steel for the Continuous Casting Shop to further produce cast blooms for the Rail & Structural Mill and cast slabs for the Plate Mill.
 
Converter ‘C’ has been in operation with the same set of refractory brick lining on the inside since April 2009. The total volume of crude steel produced by the converter is around 1.49 million tonnes. The magnesium-carbon bricks that are used inside the converter vessel for lining of the entire surface area remaining in direct contact with liquid hot metal are produced in-house at BSP’s Refractory Materials Plant-II. The job of relining is also done in-house.
  
BSP recorded its highest-ever average converter life of 7882 heats in 2009-10, surpassing the previous best figures of 6428 heats in 2008-09 and 6068 heats in 2007-08. The average converter life in Bhilai is the best in SAIL.
 
BSP Managing Director V.K. Arora said that the achievement is a reflection of the technological and operational discipline and maintenance practices in the plant. It is also a significant achievement with regard to cost-control measures in an integrated steel plant, he added.
