摘要： A fire resistant steel structure (10) comprises a steel beam (14) for receiving a vertical load and a support structure for supporting the horizontal beam (14) at two horizontally spaced locations. At least one fire-resistant tension member (30) has its ends (32, 32') anchored outside the steel beam (14) in the support structure. It is arranged relative to the steel beam (14) in such a way that when the steel beam (14) is overheated and yields under the vertical load in case of severe fire conditions, it rests on the at least one fire-resistant tension member (30) and is vertically supported by the latter.

摘要： A continuous casting process of a steel semi-product is provided. The process includes a step of casting using a hollow jet nozzle located between a tundish and a continuous casting mould. The nozzle includes, in its upper part, a dome for deflecting the liquid metal arriving at the inlet of the nozzle towards the internal wall of the nozzle, defining an internal volume with no liquid metal. A simultaneous step of injecting powder through a hole of the dome occurs. The powder has a particle size of 200 μm or less. The dome includes a first device to inject the powder without any contact with the dome and a second device to avoid sticking or sintering of the powder onto the first device.

Said welded steel part according to the invention is essentially characterised in that the edges (36) in close proximity to the melted area (35) are not provided with the metallic alloy layer (19, 20) but they are provided with the intermetallic alloy layer (17, 18), and in that, on at least part of the length of the melted area (35), the ratio of the carbon content of the melted area (35) to the carbon content of the substrate (25, 26) of one of the first or second metal sheets (11, 12) having the highest carbon content (Cmax) is between 1.27 and 1.59. The invention also relates to a method for producing such a welded steel part and to the use of said welded acid part for producing structural or safety parts for vehicles, especially motor vehicles.
