Publication number: 20230249235Abstract: In preset calculation, a plurality of cooling banks are set to be feedforward or feedback banks, and each of water injection amounts in these banks is calculated. In cooling history management, a recalculation position for re-executing the feedback calculation is set. In feedback calculation, a temperature correction value for compensating a delay due to a conveyance time period from a position of the feedback bank to a position of a delivery side pyrometer, and a response delay of the feedback bank is calculated, when a segment reaches the recalculation position. In the feedback calculation, each of water injection amounts in the feedback banks that is calculated in the preset calculation is changed for each of segments based on a delivery side temperature target value, a delivery side temperature actual value calculated for each of the segments, a delivery side temperature prediction value that is recalculated, and the temperature correction value.Type: ApplicationFiled: June 15, 2021Publication date: August 10, 2023Applicant: TOSHIBA MITSUBISHI-ELECTRIC INDUSTRIAL SYSTEMS CORPORATIONInventors: Kazutoshi KITAGOH, Hiroyuki IMANARI, Naoki SHIMODA, Yuki OKANO, Sanga TAKAGI

Patent number: 10710133Abstract: A temperature calculation method includes: dividing a cross section perpendicular to a longitudinal direction of a steel plate to be hot-rolled into a plurality of rectangular elements; and calculating a temperature of each of the rectangular elements using a finite difference method. A first region 31 that includes an edge part of the cross section is divided such that a plurality of the rectangular elements are lined up in a plate-thickness direction and such that a plurality of the rectangular elements are lined up in a plate-width direction. A second region 32 that includes a center of the cross section and is wider than the first region 31 is divided such that a plurality of the rectangular elements are lined up in the plate-thickness direction but the second region 32 is not divided in the plate-width direction.Type: GrantFiled: March 26, 2015Date of Patent: July 14, 2020Assignee: TOSHIBA MITSUBISHI-ELECTRIC INDUSTRIAL SYSTEMS CORPORATIONInventors: Naoki Shimoda, Haruki Inami, Mirei Kihara

Patent number: 10482406Abstract: In an energy-saving-operation recommending system, a total energy consumption of plural facilities during passage of one material to be rolled through a rolling line is calculated, and the total energy consumption is divided by a width and a length of the material to be rolled before rolling to calculate an energy consumption reference value that defines energy consumption per unit width and unit length of the material to be rolled. The energy consumption reference value is stored in association with a steel grade and a target post-rolling plate thickness of the material to be rolled. An energy consumption reference value corresponding to a steel grade and a target post-rolling plate thickness of a material to be next rolled on the rolling line is obtained. The energy consumption reference value is multiplied by a width and a length of the material to be next rolled to calculate predicted energy consumption.Type: GrantFiled: August 2, 2013Date of Patent: November 19, 2019Assignee: TOSHIBA MITSUBISHI-ELECTRIC INDUSTRIAL SYSTEMS CORPORATIONInventors: Naoki Shimoda, Kazuhiro Ohara, Hiroyuki Imanari

Patent number: 10464112Abstract: An energy-saving control device for a rolling line, the energy-saving control device capable of finding rolling conditions for minimizing energy consumption for the rolling line while ensuring a quality of a product. The energy-saving control device for a rolling line includes: an energy consumption estimating unit that calculates energy consumption for the rolling line based on rolling conditions for the rolling line; and an energy consumption optimizing unit that changes a rolling condition other than a target temperature of a material to be rolled, as a manipulation item so that the energy consumption calculated by the energy consumption estimating unit is reduced while a quality of a product formed by rolling the material to be rolled is ensured.Type: GrantFiled: February 4, 2013Date of Patent: November 5, 2019Assignee: TOSHIBA MITSUBISHI-ELECTRIC INDUSTRIAL SYSTEMS CORPORATIONInventors: Hiroyuki Jinnai, Hiroyuki Imanari, Naoki Shimoda, Kazutoshi Kitagoh
