Abstract: The invention relates to a method for operating a steelworks, for example in a blast furnace converter route, or with a direct reduction of iron ore with hydrogen with downstream electrical steel route, preferably additionally a secondary steel route. To carry out the method, the following are balanced: A) a number of starting material flows of supplied starting materials, B) a number of by-product material flows from emitted by-products, and C) a number of energy flows of used energy.

Abstract: The present disclosure relates to a process for producing an iron melt. The method includes; reducing iron ore to sponge iron, carburizing sponge iron with a carbonaceous gas, melting the carburized sponge iron and/or treating the melt produced from the carburized sponge iron. According to the present disclosure, the carbonaceous gas is at least a portion of the process gas obtained in the melting of the carburized sponge iron and/or treating of the melt produced from the carburized sponge iron that has been recycled.

Abstract: The present disclosure relates to a method for producing steel in an integrated metallurgical plant comprising at least one direct reduction reactor for directly reducing iron ore to give sponge iron, at least one electric furnace for melting the sponge iron to give pig iron or crude steel, at least one blast furnace for smelting iron ore to give pig iron, and at least one converter for refining pig iron to give crude steel. In accordance with the invention, the process gas discharged from the direct reduction reactor is admixed at least partly to the hot blast air and/or at least partly to an optional charging material, said air and/or said material being blown into the blast furnace.

Abstract: A method of producing pig iron in a shaft furnace is provided. The shaft furnace is charged in an upper region with raw materials which fall within the shaft furnace under the influence of gravity. A portion of the raw materials is melted and/or partly reduced under the action of the atmosphere that exists within the shaft furnace. A hot gas stream which is introduced in a lower region of the shaft furnace flows through and influences the atmosphere that exists within the shaft furnace in terms of chemical composition and temperature. A cold gas stream is fed to a heat exchanger in which the cold gas stream is heated to a temperature higher than 700° C. to give a hot gas stream. The cold gas stream comprises a CO2 component of at least 5% by volume. The cold gas stream may contain, air and/or pure oxygen as residual component.

Abstract: An augmented mirror comprising: a partially silvered mirrored surface; a screen underneath the mirrored surface; a camera; and a computer module for receiving data from the camera and for providing graphical images to the screen, wherein the field of view over which visual information is processed is reduced to visual information from within a visual corridor, the visual corridor corresponding to a subset of the field of view of the camera.
