Patent number: 10065226Abstract: 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.Type: GrantFiled: August 28, 2015Date of Patent: September 4, 2018Assignee: NORTHEASTERN UNIVERSITYInventors: Zhaodong Wang, Bingxing Wang, Junyu Wu, Tian Zhang, Yong Tian, Yi Han, Tianliang Fu, Yong Li, Guodong Wang

Patent number: 10065225Abstract: Control of third octave vibrations in a mill stand can be achieved using a high-speed piezoelectric assist coupled to a hydraulic gap cylinder to increase the damping of the roll stack. Vertical movements of the roll stack (e.g., the top work roll) can be determined through observation (e.g., measurement) of hydraulic fluid pressure of the hydraulic cylinder or entry tension of the metal strip. After determining vertical movements of the roll stack, a desired change in hydraulic pressure can be determined to overcome, reduce, or prevent third octave vibration. This desired change in hydraulic pressure can be effectuated at high speeds (e.g., at or above approximately 90 hertz) using the piezoelectric assist.Type: GrantFiled: July 15, 2015Date of Patent: September 4, 2018Assignee: NOVELIS INC.Inventor: Rodger Brown

Patent number: 10062460Abstract: A sealing member is provided to create a sealed region about an annulus formed between an inner body, such as a thermal sleeve, and an outer body, such as a control rod drive housing nozzle. Liquid is introduced into the sealed region to create a flooded region, which is pressurized to a desired level. A nozzle is provided into the flooded region, the nozzle being configured to fit within the annulus. Pressurized fluid is ejected from the nozzle, causing the formation of cavitation bubbles. The nozzle flow causes the cavitation bubbles to settle on the surfaces forming the annulus. The collapsing impact of the cavitation bubbles imparts compressive stress in the materials of the surfaces forming the annulus.Type: GrantFiled: November 26, 2014Date of Patent: August 28, 2018Assignee: Framatome Inc.Inventors: Gary R.
