摘要： A method for flattening steel strip by cold rolling the strip by passing it through at least two cold rolling mill stands each having work rolls. A first of the mill stands has work rolls having local rigidity K significantly different from a second mill stand, wherein the local rigidity K is calculated in Kgf/mm/mm accordance with an equation. Also a six high mill for flattening steel strip has an entry side where the strip enters the mill and an exit side where the strip exits the mill. The mill comprises a pair of driven backup rolls disposed on the entry side of the mill, a pair of horizontal support rolls disposed on the exit side of the mill and a pair of small diameter work rolls, the work rolls having an entry side face and an exit side face. The work rolls are disposed between the pair of backup rolls and the pair of support rolls. The entry side face of the work rolls is in engagement with the backup rolls during operation and the exit side face of the work rolls is in engagement with the support rolls during operation.

摘要： The present invention provides a bottom nozzle filtering device and a debris-preventive bottom nozzle that can be used for a light water reactor (LWR) nuclear fuel assembly. The bottom nozzle filtering device includes a plurality of successively spliced unit plates; a through flow channel is formed between the spliced adjacent unit plates; the flow channel includes a plurality of spaced straight-section flow inlets and straight-section flow outlets, and a flow subchannel communicating; the outlet section of each straight-section flow inlet in the middle splits respectively into two flow subchannels, and the inlet section of each straight-section flow outlet in the middle communicates respectively with the two flow subchannels. The flow direction of the coolant is controlled by the straight-section flow inlet, the straight-section flow outlet, the flow subchannel to prevent unnecessary eddies forming, making the pressure loss effectively controlled and improving the filtering effect.

摘要： A method for flattening steel strip by cold rolling wherein the strip is passed through at least two cold rolling mill stands each having work rolls. A first mill stand has work rolls having local rigidity K significantly different from a second milled stand. The local rigidity K is calculated in Kgf/mm/mm in accordance with an equation. A six high mill comprises a pair of driven backup rolls disposed on the entry side, a pair of horizontal support rolls disposed on the exit side, and a pair of small diameter work rolls having an entry side face and an exit side face. The work rolls are disposed between the backup rolls and the support rolls, wherein during operation the entry side face of the work rolls engages the backup rolls and the exit side face of the work rolls engages the support rolls.
