Abstract: A method of manufacturing molten pig iron into an electrical smelting unit. The method includes the following successive steps: providing a directly reduced iron product, feeding the DRI product into the smelting unit, feeding together with the DRI product at least one steel or ironmaking by-product-based material having an iron content upper than 20% in weight, at least a part of the iron being under an oxidized form, melting the DRI product and the at least one steel or ironmaking by-product-based material to produce molten pig iron. A steel manufacturing method using the pig iron is also provided.

Abstract: A method for manufacturing pig iron in a smelting furnace including a vessel, the method including the following successive steps: loading DRI product in the vessel, melting the DRI product to form a pig iron layer topped by a slag layer, transferring the pig iron to the desulphurization station, and injecting a silicon containing material in the pig iron in the desulphurization station. It also deals with the manufacturing of steel from the iron.

Abstract: A method for manufacturing molten pig iron into an electrical smelting furnace, the method including the following successive steps: providing a directly reduced iron product, providing a carbon and iron containing material, feeding at least a part of the smelting furnace with the DRI product in alternance with the carbon and iron containing material, and melting the DRI Product and the carbon and iron containing material to produce molten pig iron. It also deals with the manufacturing of steel from the pig iron.

Abstract: A method for manufacturing pig iron in a smelting furnace including a vessel, the method including the following successive steps: loading DRI product in the vessel melting the DRI product to form a pig iron layer topped by a slag layer and injecting a desulphurizing reagent directly in the pig iron layer. It also deals with the manufacturing of steel from the-pig iron and the associated electrical smelting furnace.

Abstract: A method for manufacturing pig iron in an electrical smelting furnace including a vessel, the method including the following successive steps: loading DRI product in the vessel, melting the DRI product to form a pig iron layer topped by a slag layer and, tapping the pig iron into a ladle, and adding a carbon containing material directly in the pig iron in the runner of at least one of the smelting furnace tap holes. It also deals with the manufacturing of steel from the pig iron and the associated electrical smelting furnace.

Abstract: A method for determining the positioning in deployed position of an expandable medical device type implant, including, from a three-dimensional image of a region of interest including the vascular structure, the following steps: determination of a centreline of the vascular structure, positioning of the IMD according to an initial position, around the centreline, simulation of the final position of the IMD after deployment, as a function of the stresses exerted by the walls of the vascular structure on the IMD, the determination of the centreline consisting in placing points so as to minimise a travel time of fluid along said points between an input point and an output point, the simulation of the final position of the IMD taking account of a level of longitudinal push-pull intended to be applied to the IMD during its implantation.
