Abstract: According to this treatment, calcium is added to ultra low molten steel or low carbon which is aluminum killed (or in the course of being killed) in order to form non-metallic deoxidation inclusions that have a melting point which is below the casting temperature; the molten metal is maintained in the chain of treatment ranging from the ladle refining installation to the copper mold with a low minimum low magnesium content of approximately 2 ppm. The inventive method increases the scope of fusibility of the inclusionary population of steels, thereby improving the castability of high aluminum-killed ultra low carbon grades without the need for argon bubbling.

Abstract: An industrial furnace has at least one assembly formed by an extruder for extracting hot gas present in a given zone of the furnace, a water/gas heat exchanger for cooling the hot gas, and a reinjecting device for reinjecting the cooled gas into a zone of the furnace situated downstream from the zone from which the hot gas was extracted. First and second sampling devices sample the hot gas at points each situated upstream and downstream from a heat exchanger and two-port valves allowing the sampling to be performed. A regulating device regulates the respective pressures of the hot gas and the cooled gas downstream from the sampling devices. A three-port valve selects the hot gas or the cooled gas and applies it to a hygrometer. An operator is informed of the results of analyses performed by the hygrometer so that the operator may compare the degree of humidity of the hot gas and of the cooled gas for each of the heat exchangers.

Abstract: Austenitic alloy for high-temperature strength with improved pourability and manufacturing, procedure for manufacturing billets and wire

Abstract: The invention concerns a method which consists in injecting into a molten metal bath to be treated, jointly but separately into the same bath zone, oxygen and carbon in a form capable of being blown (powder carbon preferably) so as to generate locally in the bath CO bubbles from those two elements, which will then be loaded in denitriding nitrogen. A stoichiometric adjustment of the carbon and oxygen inputs enable a constant carbon denitriding in the bath. The method is preferably applicable to the production of low-carbon steel grades, in particular in an electric oven.
