  • Patent number: 11945015
    Abstract: A semi-automatic adjustment device for suppressing tension fluctuations during a rolling process of an ultra-thin strip includes a semi-automatic tension regulator, a semi-automatic tuned mass damper of variable stiffness and damping, a coiler, a tension roller and a twenty-high roller system. The semi-automatic tension regulator is disposed between the coiler and the tension roller, the semi-automatic tuned mass damper of variable stiffness and damping is disposed between the tension roller and the twenty-high roller system. The semi-automatic adjustment device can be used to reduce a short-time fluctuation impact of tension during startup and shutdown of a twenty-high roll mill when the twenty-high rolling mill rolls an ultra-thin strip, improve system stability, absorb the continuous micro disturbances generated during the rolling process of the twenty-high roll mill, and achieve flexible and stable adjustment of tension during the rolling process.

  • Publication number: 20230156873
    Abstract: Disclosed is an electromagnetic-induction heating device for a thin film thermocouple on a ceramic blade, including a spiral coil. The ceramic blade is enveloped in the spiral coil, and two ends of the spiral coil are both connected to an electromagnetic-induction heater. The ceramic blade is arranged in an alumina ceramic chamber, and the thin-film thermocouple is arranged on a surface of the ceramic blade. One end of the air channel is connected to an end of the alumina ceramic chamber, and the other end of the air channel is connected to an infrared nod temperature instrument and a vacuum pump. The infrared nod temperature instrument, the electromagnetic-induction heater, and the vacuum pump controller are electrically connected to the controller.

  • Patent number: 11598676
    Abstract: Provided herein is a tungsten-rhenium composite thin film thermocouple based on a surface micropillar array with gas holes. A tungsten-rhenium thin film thermocouple is arranged on a surface of a flat alumina ceramic substrate. Two tails of the tungsten-rhenium thin film thermocouple are respectively connected to a lead wire. A surface of the tungsten-rhenium thin film thermocouple is arrayed with a plurality of micron alumina micropillars to form an alumina micropillar array. Air is filled between the micron alumina micropillars to form the gas holes. The flat alumina ceramic substrate, the tungsten-rhenium thin film thermocouple and the alumina micropillar array form a three-layered laminated structure.

  • Publication number: 20100098071
    Abstract: Method for transmitting packet in resilient packet intersect ring includes: at least two resilient packet intersect ring intersect each other on two intersect node, the intersect node receives a broadcast packet from the first resilient packet ring, and copies the said broadcast packet; the said intersect node judges whether allowing to insert the said broadcast packet into the second resilient packet ring by spanning the ring according to the identification information included in the said copied broadcast packet, if so, inserting into the second resilient packet ring by spanning the ring and broadcasting, otherwise, discarding the said broadcast packet, the control condition of allowing to broadcast by spanning the ring of all intersect nodes is null. The invention can ensure that when all intersect nodes can transmit spanning ring server, it avoids spanning ring broadcast storm. The invention is applied to the case that several resilient packet rings intersect each other.
