India’s Steel Industry is more than a century old. Before the economic reforms of the early 1990s the Indian steel industry was a predominantly regulated one with the public sector dominating the industry. Tata Steel was the only major private sector company involved the production of steel in India. SAIL and Tata Steel have traditionally been the major steel producers of India. In 1992‚ the liberalization of the India economy led to the opening up of various industries including the steel industry

Changes in legislation could have severe impacts on the firm’s numerous production facilities and could be costly to become compliant. The fluctuations in both the cost and supply of iron ore and scrap steel directly impact the firm’s profitability because it is difficult to pass those costs on to the customers due to the price-driven level of competition in the steel industry. The rise

discovered. This microstructure was named by Bian’s colleageus at the United States Steel Corportion. At first microstructure of martensite and bainite seem similar‚ which had many aspects on their transformation of mechanisms. Microstructure of bainite seems to be darker than the mastenisite under a microscope. The reason behind bainite structure became useful was because of its hardness. There are few Heat treatments that steel can be tested by such as Annealing‚ quenching Harderning‚ and Normalizing.

The Classification of Steel Ball There are two kinds of steel ball‚ casting steel ball and forging steel ball. Casting ball manufacturers mix scrap steel‚ scrap metal and other waste metals in intermediate frequency electric stove for heating so as to fully melting. Right amount precious metal alloy‚ such as ferrochrome‚ ferromanganese‚ vanadium iron are added in melting process. When temperature is above 1550 ℃‚ powering hot metal to the steel mold or mold steel ball production line. This kind

Ms Sanghamitra‚ R&D Refractory Department from TATA STEEL‚ Jamshedpur‚ gave a talk on “STEEL MAKING REFRACTORY”‚ on 12th September 2012 at 11:00 AM at Ceramic Engineering department. Process chart of TSL‚ INDIA was first addressed. So‚ it all starts with iron ores and fluxes (limestone) to be mixed and then pelletized in a sinter plant. At the same time‚ raw coal is processed to form coke in a coke plant and then sintered pellets along with coke are fed to a blast furnace. Hot metal is obtained

Steel Making Methods | Advantages | Disadvantages | Basic Oxygen Furnaces | * Very high production rates and low residual element * Does not burn fuel | * Good efficiency requires large amount of pig iron to continue production. * Requires costly filtering process due to high levels of pollutants produced. * High refurbishing costs. * High dependence on blast furnace/coking. | Electric Arc Furnaces | * Minimal emissions/pollution. * Filtering of scrap not necessary. * Easy

above complex approach actually worked‚ over these four years? What was the outlook (as of the case date) for further progress in this matter? In 1975 Chaparral Steel commissioned minimill and started production. Minimills are different from traditional integrated steel plants. In minimill an Electric Arc Furnace (EAF) is used for steel making purpose and in downstream long product is made using rolling mill. The advantage of minimill is it requires less capital investment and a good solution when
