In spite of early learning phase of stamp charge operation, the 1st stamp charge battery of Tata Steel achieved life more than 27 years and still having some residual life. Optimization of coal blend on the quality of coke, battery health, cost of blend along with modified standard operating practices and well-designed oven health monitoring and repair practices are the backbones of this achievement. Stamp charging technology has provided a high degree of flexibility and offered substantial savings in coal blend costs which, in turn, had a positive impact on the coke cost and hence on the cost of hot metal. Another important aspect of this journey of excellence in stamp charge coke making is a culture of development and improvement adopted by Tata Steel. Work on understanding coal behavior in stamp charge condition, its impact on oven health and proper blending to achieve the best quality yielded immense benefit to blast furnaces. Self-learning through a process of change orientation made this coke making unit a leader in this field.
Key words: coke making technologies / operational philosophy / structural stability / environment / coke quality
