With stricter regulations and increasingly demanding customers, steelmakers are turning to new carbon-friendly materials and processes. These materials include green hydrogen, Green briquetted iron, desulfurized slag, and limestone containing magnesium. In this article, we'll take a closer look at the different types of these materials and their potential to benefit the steel industry.
Hydrogen, for example, is a renewable, clean, and reusable fuel that can be produced from ordinary water through electrolysis. In steelmaking, the hydrogen will replace carbon. This means that the steel industry will reduce the amount of CO2 it emits, while still producing steel.
The steel industry's energy demands have been reduced by 50%, according to the World Steel Association. However, it's widely recognized that these efforts are not enough. The steel industry needs significant support to shift from its current methods to a more sustainable one.
Studies have been conducted in the field to determine the feasibility of using biomass as a coke feedstock for steel production. Researchers at Hooeya, Finland, investigated biomass in a steelmaking plant. They also evaluated the economic, environmental, and waste management aspects of the biomass.
The production of green steel requires significant carbon reduction. To achieve this, manufacturers must use less coke than they do today. One way to reduce CO2 emissions is to use green briquetted iron instead of scrap. This is a highly efficient way to make steel while reducing emissions and producing oxygen.
Limestone is a sedimentary rock that is a source of calcium and magnesium. Limestone is processed into several different products. Limestone comes in three major sizes: powder, fine, and lump. Limestone contains appreciable amounts of magnesium and is composed of 90% calcite and a tiny amount of dolomite.
Dolomite is a valuable mineral that can be mined for many purposes. It's used as a refractory, sealing, and electrical insulation material. China has huge reserves of dolomite. This mineral has an important role in the development of China. The composition of dolomite varies depending on its location.
Desulfurized slag is essentially a mixture of carbon products. The addition of Fe2O3 lowers the sulfur content and increases the activity of NiO and CoO. The addition of CoO does not affect the sulfur content of desulfurized slag.
Desulfurized slag is an intermediate step in the steelmaking process. In the past, the process was to tap the composition of the steel in the EAF at extremely low levels. After tapping, the slag underwent partial desulfurization in the ladle. In addition to FeO, FeSi, and aluminum were added to the slag before it was transported to the VTD.
Desulfurized slag is an intermediate step between nickel converter slag and the metal. The process produces a metal that contains less sulfur than matte. The process removes sulfur from the slag by reducing its metal oxides.
