HOt STRIP MILL LAYOUT and WORKING

Image
it is after steel processing  .molten steel is converted in slab and billet . slab is USED IN making a strip and billet is used in making a wire and rod .after slab is going in hsm (hot strip mill)where it is converted in strip. this strip is called hot strip.it colour is black.it has some impurity like percantage of  carbon is high. so its colour is black. it has low tensile and yield strength as compare then cold strip. first of all slab is  passing from furnance. furnance is heated the slab and after it passing through a roller and high pressure water is apply on it and remove a slag . after it passing a roughing mill where its thickness is decrese and width and length is increase. afteris transfer table and shear of its front end ..and at last it passing from finishing mill where its increase the roughness and at coiler  it wrapped in coil.it has depend on dimension and weight below 30ton called normal coil and greater than 30ton coil is called JUMbo coil.HSM coil is directly use

steel making process from raw material to final sheet making

for steel making it pass many steps 1.iron ore is extracted from mines. after it is goes in benification plant .Benefication is  a process in which iron ore and sand is seprated through centrifugal machine. it seprate iron ore ,sand and other impurity. after it goes in RMHS ( raw material handling system) where raw raw material is transfer from other department. raw material is transfer by conveyour belt. 2.After RMHS material goes in agglomeration process. Agglomeration  process is divided in two parts  Sinter and Pallet Plant. Sinter is mixture of iron ore flux and other additives it has size approx 20 to 30 mm. and it is used in Blast Furnance. Pallet is also mixture of iron ore flux,limestone etc. it has good quality compare than sinter.it has size approx 8 to 16 mm. 3.coal is coming from foreign as well as india's country.coal has four category 1. pit 2. lignite 3. anthresite 4. bituminus .in which bituminus and anthresite coal has large calorific value so these are use in

difference between JSW vs TATA Steel

Image
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

Top Steel Ranked Company Interview

 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
