Abstract:
To produce sheet steel components optimised for loading, a steel strip is cast between two cooled rolls with a variable nip and the thickness of the steel strip is changed by changing the time of contact between the strand shells and the rolls or by changing the cooling intensity of the rolls on the molten steel cast into the gusset formed by the rolls, thereby changing the thickness of the steel strip. Such a strip has a homogeneous structure and can subsequently be given a special quality by hot or cold rolling for its particular purpose of use.
Abstract:
The invention relates to a protective coating for a refractory material member of an ingot mold for continuous casting of metals, especially of steel, which consists of a dispersion of particles in a solvent, said particles including essentially boron nitride and at least one of the following metal oxides: zircon, zirconia, alumina and silica, the boron nitride representing between 20 and 50% by weight of said particles.
Abstract:
A steel strip can be produced which in spite of its high manganese content has good deformation behaviour in that, according to the invention, from a steel which comprises more than 12 to 30 weight % of manganese, a roughed strip (V) is cast close to the final dimensions in a double-roller casting machine (2), said roughed strip comprising a thickness of up to 6 mm. Following casting, this roughed strip is further processed to form a continuous hot strip by preferably being rolled in a single hot roll pass.
Abstract:
The invention relates to a method and a device for the production of a strip-like metallic composite material by the high-temperature dip coating of a metallic carrier strip, consisting of a metallurgic vessel for receiving the liquid depositing material, through which the carrier strip is capable of being led in a preferably vertical run-through direction by means of pairs of rollers arranged on the entry and the exit side, and of a preheating device for the carrier strip, said preheating device being located upstream of the metallurgic vessel. At the same time, the preheating device (41) is arranged in a housing (61) which is arranged in the entry region upstream of the metallurgic vessel (11) and surrounds the carrier strip (21) and into which the medium coming from a media supply (52) is capable of being introduced via at least one feed (51) led into the housing.
