82 Jindal Steel & Power Limited Business Leadership Sustainable Operations Excellent Governance Robust FinancialsDirectors’ ReportAnnual Report 2011-1283B. Benefits derived as a result of the above R&D:1. New section developed to cater to the customer requirements in the field of seamless line pipe application.2. New grade developed to cater to the stringent quality requirements of the customers for critical line pipe application withextra low sulphur content.3. The reduction in defects will reduce the rework cost. The dispatch schedule will not get hampered due to elimination ofrework activity on plates.4. By development of this new grade the Company is now able to supply special quality plates in a new market segment.5. A detailed report was generated on trial conducted at slab caster of the Company and suggested to supplier for furthermodification in flow pattern to improve the product quality.6. The Company is in a position to supply plates in new market segment with stringent quality standards.7. Based on data analysis and observations, recommendations were given to minimise RBP in structurals.8. The Company is in a position to supply Beams in new market segment with stringent quality standards.9. The Company is in a position to supply Sheet Piles for new market segment with stringent quality standards.10. The Company is in a position to supply Medium Light structural grades for new market segment with stringent qualitystandards.11. New grade (12L14) has been developed to cater to the business in a new market segment. “Free Cutting Steel - 12L14” hasbeen developed which is widely used as Machining quality steel grade.12. The hearth monitoring system was installed in Blast Furnace-2 which helps in controlling the PCI injection rate and oxygenflow through tuyers. It also helps in continuous monitoring of the inside refractory wall pattern in hearth.13. This has led to considerable saving till now and will also generate future savings.14. Trials confirm that average CSR of coke from pilot coke oven is 4 points lesser than Main coke oven and similarly average CRIof coke from Pilot coke oven is 4 points higher than Main coke oven. With the help of these results, trials can be conductedat pilot coke oven with the help of which the values would be predicted at main coke oven with a higher precision.C. Future Plan of Action:1. Study on reduction of ovality in cast rounds.2. Analysis of MMR of individual and blended coking coal for coal characterisation and establishing the relationship to predictCSR and CRI of coke.3. Study the root cause of formation and remedial actions for accretion formation in DRI kilns with collaboration of NationalCouncil for Cement and Building Materials, Ballabhgarh.4. Establishing the correlation between CSR – CRI results of Pilot Coke Oven and Commercial non recovery Coke Oven.5. Optimisation of maximum percentage use of non coking coal in blending of coking coal through pilot coke oven study toreduce the production cost.6. Commissioning of slag detection system and study its effect on steel quality.7. Study on the enhancement of the Roll campaign life.8. Study on root cause analysis and remedial measures for centerline cracks in billets in low carbon grades.9. Recycling and reuse of formed accretion in coal based DRI Kilns.10. Study the Apex radius at MLSM.D. Expenditure on R&D during 2011-12:a. Capital : ` 2.51 croreb. Recurring : ` 6.46 crorec. Total : ` 8.98 crored. Total R&D expenditure as a percentage of total turnover : 0.07% (turnover 13,270.67 crore)15. The Company is in a position to supply plates in a very prestigious market segment with stringent quality standards.16. Specific coal consumption (per ton) reduced.
