आप  सभी लोग चीन  के विषय में जानते हो। कि चीन वर्ल्ड  में  स्टील  उत्पादन में  पहले नंबर पर है। क्योकि वहाँ आयरन अयस्क और  सभी स्त्रोत उपस्थित है। चीन का लगभग एक साल का स्टील उत्पादन  810 मिनियन टन है।लेकिन ये बात भी उतनी ही सच है  की चीन प्रदूषण में भी काफी आगे है  बीजिंग जो चीन की राजधानी है वहां आपका बिताया एक दिन 40 सिगरेट जितना नुकसान पहुंचाता है। 1. ArcelorMittal ArcelorMittal, who operates in more than 60 countries, is headquartered in Avenue de la Liberte, Luxembourg. It was formed in 2006 by the merger of Arcelor and Mittal Steel. The company has 232, 000 employees and it produces 10% of the world’s steel.it has production approx 90 mt/annum. 2. Nippon Steel & Sumitomo Metal Corporation (NSSMC)  Nippon Steel first company in steel industry who first deming prize in world 1972. Nippon Steel & Sumitomo Metal Corporation (NSSMC) was manufactured in association with the Nippon Steel and Sumitomo Metal in 2012. NSSMC is the second largest steel provide

JSW Steel ranks tenth. It has high emissions and energy intensities, though has demonstrated progress in reducing them in recent years. Its emissions reduction target runs only to 2016, and it apply appear to be involved in significant breakthrough emissions reduction technology research. Scope of report: Company selection .it uses some reduction of smoking emmission technology.  Tata Steel ranks second last. It provides limited transparency relative to other companies, only providing substantive environmental data for its Indiabased operations, representing only one-third of its operations by tonnes of steel produced globally. This lack of fully consolidated environmental disclosure provides investors with limited perspective of its environmental risks and performance and resulted in its omission from several quantitative benchmarking exercises. If it were included, its disclosed India-only emissions and energy intensities rank worse than average. It is also subject to

 1. POSCO is ranked first and performs strongly across most key areas. It has a below average emissions intensity, and unlike several other steelmakers has demonstrated an ability to reduce its emissions intensity significantly in recent years. Its targets are consistent with a 2-degree sectoral decarbonization pathway as far as its target expiry in 2020. It has developed and commercialized a technology FINEX, providing incremental emissions reductions from steelmaking by eliminating sintering and coke oven processes. The technology has potential to be combined with CCS due to high concentrations of CO2 in waste gases. It also has other active projects to separate and capture CO2, and has undertaken early stage work on CCU and hydrogen-based steelmaking. 2 .SSAB   :  ranks second. Its emissions intensity is low, driven by significant electric arc furnace (EAF) operations, and Europe-based blast furnace-basic oxygen furnace (BF-BOF) plants that it states benchmark as among the mo

iron ore is found in india at different different place .it is major found in karnataka. it is also found is chhitisgarh,jharkhand,oddisa,goa etc.in karnatka there are lot of mines and there has major iron ore.there are some iron mines 1.nandi halli 2.shimore mine 3. tunga & bhadre 4.davdari mine 5.rama  these are famous for iron mines. The total recoverable reserves of iron ore in  India  are about 9,602 million tonnes of hematite and 3,408 million tonnes of magnetite. 

Generally steels has lots of grade and it has different veriety but steel has mainly four types. 1. Carbon Steel 2. stainless Steel 3. Alloy Steel 4. Tool Steel.       Carbon Steel :-  A carbon steel only require carbon to create a successful alloy .it has required some amount of alloy like as chromium, tungstun,nickel etc. Generelly greater the  carbon content  steel hard, improve the strengh  and impact resistence.     Stainless Steel :-  Stainless steel has some amount of alloy is required.it is used in kitchen.there is mixture is approx 10-11% chromium.it is corrosion less and it has also long life.         Alloy Steel :-  As a name indicate it is alloy means it has large amount of alloy .it improve mechanical property of steel. it has approx 1-50% of alloy required .it improve hardened ability and corrisionless.    Tool Steel :- These are collection of steel & alloy ,colectively groupedbecause their particular make them ideal for making a tool. these are commonly

steel is made of many content like iron ore, coke, coal,flux etc.directly iron ore is not used in steel.it is converted in sinter and pallet.these composition has so much different. so it shown below content          iron ore          sinter             palllet  Fe                   61-62%          53-54%        59-60%                 Feo          .04-0.6%              9-11%           0.6-0.8% Sio2             3-4%              5-6 %                 4-7% Al2o3          3-4%               3.5-4.5%            4-5% Mgo             .01-.015%         2-2.5%           .30-.35% Size                10-50mm        15-25mm       8-16mm NOTE :- Iron ore is fund in mines in mix composition.in starting it crushing and benification (means seprate of iron ore and sand). after it converted in sinter and pallet through agglomeration.

Around in this world there has approx 2 lakh of steel grade is found .In which there are some grade of steel if (interstantial free),HRPO (hot roll pickled oil,HRSPO (hot roll skin pickled oil),DQ (deep quality),DQFH( deep quality full hard).some grade of steel is used in refrigerator,pipes,vessel, drum etc. but  highly grade of steel is used in automobile sector.These steel has high quality and long life and high mechanical property.  

steel is used from ancient time.now this time there has approx .2 millon gades of steel.but"iron pillar"(350-380 ad)of delhi is also mystry of all resercher and scientist.there  are no adject composition of meterial. in ancient time people are uses iron that time there has no knowledge about steel.
