Brief description of the continuous casting coulee hollow and device for implementing it.

摘要

P the invention relates to the metallurgical treatment. / p & & p & the casting process forming the subject of the invention is characterized in that, during the extraction of the molding, 4, the intensity of the evacuation of heat to the surface of the molding varies progressively, in the direction of the height of the ingot mould 3, from a certain maximum value in the zone of the initial formation of the solidified thickness, up to a certain minimum value at the location where the molding of the ingot mold, and in that the extraction speed of the molding of the ingot mold at each extraction cycle of said molding progressively increases from zero to a maximum value for a period of time corresponding to half the duration of the movement of the molding, it then decreases progressively to zero during a period of time equal to the preceding / p & & p & the invention applies in particular for manufacturing sleeves of a cylinder of a piston rings, of the sockets and other parts of first importance of the mechanical construction, etc... / p
