摘要： The present invention relates to controlled cooling in manufacture of steel plate, and in particular, to an on-line cooling system for controlled rolling with an inter-pass cooling process, which comprises a rolling mill and on-line cooling equipment. The cooling equipment is accessorily arranged on the exit of the rolling mill, so that the rolling mill and the cooling equipment are combined. One rolling mill and one set of on-line cooling equipment are considered a cooling group, and several such groups are connected in series, so the steel plate can be cooled in any rolling pass. In this invention, both the cooling system and the water supply system are arranged on the main frame, and the rolling process and the cooling process are synchronized by using inter-pass cooling. Consequently, satisfied rolling effect in the condition of a temperature gradient along the thickness direction, grain refinement at the surface and drastic strength improvement without sacrificing toughness are achieved. Besides, better quality of the plate center region is obtained, double bulging is avoided and the yield of steel plate is improved due to the higher deformation permeability.
摘要翻译：本发明涉及钢板制造中的受控冷却，特别涉及一种包括轧机和在线冷却装置的通过冷却过程的用于控制轧制的在线冷却系统。冷却设备配置在轧机的出口处，使轧机和冷却设备组合。一台轧机和一套在线冷却设备被认为是一个冷却组，并且几个这样的组被串联连接，因此钢板可以在任何轧制过程中被冷却。在本发明中，冷却系统和供水系统均布置在主框架上，并且通过使用冷却流程来同步轧制过程和冷却过程。因此，在沿着厚度方向的温度梯度的条件下，在表面上的晶粒细化和强度提高而不牺牲韧性的情况下实现满意的滚动效果。此外，获得了更好的板中心区域的质量，避免了双重凸起，并且由于较高的变形渗透性而提高了钢板的产量。

摘要： An apparatus and method for controlling the quality of cylindrical or other geometrically regular-shaped products, such as tube or rounds, through high precision, continuous, real-time three-dimensional analysis of hot or cold products during their manufacture are disclosed. The apparatus includes multiple penetrating radiation sources and detectors. The apparatus is able to continuously and in real time perform a three-dimensional analysis of hot or cold products, detect cross-sectional and longitudinal flaws in the products, determine the processing steps causing the flaw, and modify the production process through feedback and/or feedforward control of the processing equipment. In performing the analysis on hot or cold products, the apparatus can determine the dimensional measurements of the products at other temperatures and take these measurements into consideration while controlling the manufacturing process in order to produce products of consistent dimensional quality.

摘要： A closed loop temperature control system for use in tandem rolling mills. The closed loop temperature control system uses dynamic information about the temperature of the material moving through the mill to adjust the work rolls to adjust the amount of thickness reduction between the stands to control the temperature of the material as it moves through the mill. In one embodiment, the control system is configured to eliminate or reduce temperature differences across the length of the material as the material moves through acceleration, steady state, and deceleration stages of the rolling process.

摘要： Before a first strip point is fed into a production line, an actual energy content at a location in front of the production line and a setpoint energy content at a location behind the production line are received for a first strip point, second strip point, and third strip point. The third strip point, followed by the first strip point, followed by the second strip point, are fed into the production line. A command variable for the first strip point and second strip point(s) is determined prior to feeding in the first strip point. Each command variable is determined based on (a) the actual value and the setpoint value of the strip point currently entering the production line, and (b) the actual value and the setpoint value of at least one strip point having already entered.
