摘要： A bimetallic composite back-up cylinder for a rolling mill, in particular for a four-roll or six-roll stand of a hot strip train finisher, comprises a metal envelope made of a steel having a chromium content between 13 and 17 wt. %, and a carbon content between 0.5 and 0.8 wt. %, the chromium/carbon ratio being between 20 and 25.

摘要： A bimetallic composite working cylinder has an external shell made of an alloy containing iron, carbon, vanadium, chromium and molybdenum. The range of composition of the alloy represented on a carbon-vanadium curve is delimited by a quadrilateral whose sides are: a) the constant ordinate line V=3 wt.%; b) the constant abscissa line C=3wt.%; c) the peritectic line separating the delta et gamma phase regions; and d) a straight line which determines the maximum permissible vanadium content passing through two points with co-ordinates C=1.8 %, V=6% and C=3%, V=4.5%, respectively. The core of the cylinder is made of nodular graphite iron.

摘要： A system for recognizing characters engraved on a passing medium and consisting of segments arranged perpendicularly to each other. By using CCD-type cameras (CAV, CAH) linked to each of two light sources (SH, SV) which enhance the two different kinds of segment of each character, the system picks up the signals from both cameras, detects the first and second types of segment using the signals from each of the cameras, then by roughly locating one of the kinds of segment and more finely locating the other kind of segment, and then by comparing them to a selected character font, identifies the detected character. The system can be used for recognizing characters engraved on media in order to identify and check said media.

摘要： A magnetic field is generated by means of an emitter (10) situated at the vicinity of the surface (S) of a product to be tested and a receiver (11) distinct from the emitter is arranged, with respect to the emitter, on one hand so as to be aligned with the emitter in a direction corresponding to the general orientation of the defects to be detected at the surface of the product and, on the other hand so as not to be substantially influenced by Foucault currents generated by the emitter when the product surface is free of defects so that a significant signal is received by the receiver only in the case of deviation of the Foucault currents to its direction due to a discontinuity (D) and the surface of the product. The invention is applied to the detection of surface defects of metallurgical semiproducts, particularly continuously cast iron and steel semiproducts.

摘要： An alternating magnetic field is generated to cause Foucault currents to circulate at the surface of the product (B) by relative motion with a detector, a signal representative of the variations of Foucault currents is collected by means of a differential sensor (11, 12) and is demodulated by a projection according to an adjustable phase angle to detect the perturbation introduced by the defects to be detected, said phase angle (a) being determined so that the projection of the collected signal has a minimum mean value in order to eliminate the perturbations of the collected signal due to repetitive surface irregularities; the component (Y') of the collected signal obtained by said projection is converted in digital form; the digital signal thus obtained is filtered by means of a digital filter of which the characteristics are predetermined as a function of a type of defect to be detected, and a defect detection signal is emitted when the output signal of the digital filter exceeds a predetermined threshold.
