STEEL INDUSTRY AN OVERVIEW

GLOBAL STEEL SCENARIO World crude steel production reached 1,691.2 million tonnes (Mt) for the year 2017, up by 5.3% , Share of China raised to 49%. World’s steel demand is reported to raise 1.8%, 0.7% in 2018,2019 resp. Demand in China expected to flat in 2018, drop by 2% in 2019. Demand in developing countries increase by 4.9%, 4.5% in 2018, 2019 resp. Demand in developed countries increase by 1.8%, 1.1% in 2018, 2019 resp. Australia remain biggest producer of Iron ore followed by Brazil, China, India, Russia etc

INDIAN STEEL SCENARIO India is the 3rd largest crude steel producer [101.4 Mt] in the world after China [831.7 Mt] & Japan [104.8 Mt] with a production capacity of around 134 Mt during FY 2017,175 Mt by 2022, 300 Mt by 2031. Steel sector contributes to around 2% of IGDP, employs over 25 Lakh people. Per capita steel consumption in the country is currently estimated at 63 kgs against World average 216 kgs : scope to increase consumption. Steel production has been growing at a rate of (CAGR) 5.4%.

STEEL Making Steel is mainly produced through two routes: 1. Primary Steel Making - Blast Furnace Route

STEEL Making 2. Secondary Steel Making - Electric Arc Furnace Route / Induction Furnace Pellets are used as raw material in both methods of steel making.

National steel policy 2017 Approved by Cabinet in May 2017. Per Capita Consumption to increase from present 61 Kg to 168 Kg by 2030. Target of producing 300 Million Tonne of Steel by 2030. Requires 480 Million Tonnes of Iron ore and 360 Million Tonnes of Coking Coal. Current Level is 120 Million Tonnes . Next 12 years India needs to augment capacity gradually, (both Green field and brown field) Envisages 25% utilization of Pellets in the Blast Furnaces to be set in future.

INDIAN IRON ORE - RESERVES Out of total 28.53 BT [17.88 BT - Hematite & 10.64 BT – Magnetite] Grade distribution as per available Fe% in Lumps, Fines & Blue dust High Grade: Fe > 63% - 20% Medium Grade: 60% < Fe <63% - 30% Low Grade: Fe < 60% - 50% Threat for high grade Iron Ore due to depletion. Indian ores are fragile in nature and generation of lumps & fines is 30 : 70 ratio. Orissa accounts for 34%, Jharkhand : 26%, Chhattisgarh : 19% , Karnataka : 12% , Goa : 5% Around 200 mt of Low grade fines lying idle at dumps near pit heads.

PELLETS Historically, blast furnace feedstock was naturally occurring lump ore. Large amounts of iron ore fines generated during mining. Blast furnaces could not use fines generated. High grade lump ore deposit depletion forced development of agglomeration processes. Sintering and Pelletizing are most popular agglomeration processes. Lumps, Sinter and Pellets are mainly used as burden in Blast Furnaces all over the world. In pelletisation, green unbaked pellet or ball is formed and then hardened by heating.

PELLETS Based on quality, two grades of pellets are produced World over :- Direct Reduction (DR) grade pellets. Blast Furnace (BF) grade pellets. Flux Pellets. Pellets are used as substitute to Sinter / Calibrated Lump Ore (CLO) in Blast Furnace. Low grade ore can be used to produce pellets through beneficiation technology. In an era of shrinking reserves of high-grade lump ore, pellets are gaining additional importance. It improves productivity & reduces environmental pollution.

Pelletization technology Pelletization Technology uses fines generated during the ore extraction process, once considered as waste. Travelling Gate Technology: Travelling grate technology is the proven and widely used induration furnace technology Grate Kiln Technology Circular Pelletizing Technology (introduced by Voestalpine / Siemens) – The world's most compact pelletizing plant facilitates integration at the mine or within a steelworks Pelletizing of iron ore is a method of Swedish origin, patented in 1912 by AG Anderson. First commercial plant started operation in Babbitt, Minnesota in 1952. Allis-Chalmers (predecessor company to Metso) have since built number of such plants. Kobe Steel, built their first grate-kiln plant in 1966 at Kobe Works, Nadahama, Japan. Since 2000, grate-kiln process developed by the Shougang Group has been rapidly adopted in China.

PELLET SCENARIO - INDIA India being rich in iron ore deposits did not feel the need for setting up pellet plants. Mandovi Pellets was the first plant to be set up with 1.8 Mt capacity in 1979 at Shiroda, Goa. KIOCL was the second plant to be set up in 1987 at Mangalore with 3.5 Mt Capacity. The growth of pellet industry in the country was very slow with a capacity of 20 Mt in 2010.

PELLET SCENARIO - INDIA Note : Prevailing capacity utilisation is around 60% only.

PELLET SCENARIO - INDIA Major Pellet Producers in India

PELLET SCENARIO - INDIA Integrated Steel plants in India predominantly use CLO and Sinter due to cost economics. Pellet being costly raw material, steel mills prefer to use CLO, Sinter and Pellets in that order. Industry witnessed rapid growth in last seven years with capacity crossing 85 Mt per annum. Domestic consumption of pellets increasing continuously. Globally also pellet capacity utilisation crossed 57%.

MARKET SCENARIO of pellets Marked improvement observed in Global steel demand during 2017 ( around 7%). Spot pellet premium witnessed steep rise and touched US $ 62 during Nov 2017. Demand projected to remain stable in 2018. Demand projected to improve in India by about 10% in 2018. Demand is also projected to improve in developed economies.

MARKET OUTLOOK High coke prices expected to improve demand for pellets. Implementation of stricter pollution norms, restriction on sintering in China also expected to improve the demand for pellets. China is reported to be reducing steel production capacity continuously and shutting down obsolete technology plants. Reduced production capacity and improved steel demand expected to improve demand for pellets. The move towards a more efficient steel industry, along with the enforcement of stricter environmental policies in China, should support the demand for high quality ores that enable productivity and lower emission levels.

BENEFITS OF PELLETS IN IRON MAKING Higher Yield : Higher Fe content in Pellets yields higher metallic iron in P-DRI. Higher production : Uniform shape, Porosity, high CCS, increase production of sponge iron by 15 - 20% with same amount of fuel. Higher Metallization : Low gangue content in pellets gives about 90% or higher metallization compared to lump ore (85 to 87%).

BENEFITS OF PELLETS IN IRON MAKING Less fines generation : Higher tumbler index generates very less amount of fines during reduction (about 5 to 7% compared to lump 25 to 30%). Pellets have very high cold crushing strength resulting in negligible generation of fines in stock house. Only 1-2% will be –5mm range. Good quality pellets can be produced at low SiO2 levels (1.5 to 3.5%) whereas, it is difficult to produce quality sinter at a SiO2 level of less than 4.5%, which helps slag volume reduction more than 25%. Uniform quality & superior chemistry will enhance production by nearly 10 to 15% of their rated capacity.

BENEFITS OF PELLETS IN IRON MAKING Specific consumption of coal/coke/heat energy will come down by 10 to 15%. Campaign life will increase to almost double and refractory repairing cost will be reduced by 50%. High porosity (20 to 25%) leads to faster reduction. About 10-15% less power consumption compared to sponge iron from lump ore. Emissions in sintering process are much higher when compared to pelletizing process. Decreases the emission rate CO2 by 85%, SOx by 90%, NOx by 20% compared to sinters.
