Energy Self-reliant approach of MISIL for Energy Consumption Power Generation. Mughal steel has always readily adopted to energy management technologies as it is resolved to increase energy efficiency and maximize use of waste fuels, reducing emissions as well as reliance on purchased fuels.
Thin, flat-rolled steel. Coiled sheet steel accounts for nearly one-half of all steel shipped domestically and is created in a hot-strip mill by rolling a cast slab flat while maintaining the side dimensions. The malleable steel lengthens to several hundred feet as it is squeezed by the rolling mill.
