Steel making margins jumped sharply along with utilisation rates productivity incentives are also low This encourages the use of lower grade raw materials as a cost containment measure That compresses the premiums paid for higher grade met coal and iron ore and trims the discounts faced by lower quality products In the reverse situation Abstract The availability of high grade iron ore and carbon materials for ironmaking industry decreases gradually On the contrary low grade iron ore and coals are extensively utilized not only as suplement materials but also as alternative raw materials
