20090014037 | Method and Apparatus for Cleaning or Descaling of Thin Slabs and Strips in a Hot Strip Rolling Mill Train, Strip Treatment Installations or the Like - The invention relates to a method of cleaning or descaling thin slabs and rolled strips in a hot strip rolling mill train and is characterized by use of cryogens such as oxygen or compound formed of cryogens with a carrier medium such as compressed air which are sprayed into slab surface or strip surface in liquid, deep-freeze form. The invention also relates to a method of cleaning and/or descaling of strips in a strip treatment installation with the above-mentioned characterized features, and to a correspondingly equipped apparatus. | 01-15-2009 |
20090314455 | STRAND GUIDING DEVICE AND METHOD FOR GUIDING A METAL STRIP - The invention relates to a strand guiding device and a method for guiding a metal strip, in particular a metal strip that has not yet solidified right through, in a continuous casting installation. Known strand guiding devices comprise a segment frame and at least one pair of opposing guiding rollers, between which the metal strip is guided. At least one of the guiding rollers takes the form of at least two part-rollers | 12-24-2009 |

20110094829 | METHOD AND APPARATUS FOR ROLLER LUBRICATION - The invention relates to a method for lubricating rollers, particularly for lubricating the nip in a roll stand for a rolled strip, wherein water is supplied via at least one first supply line ( | 04-28-2011 |
20120031159 | METHOD AND APPARATUS FOR COOLING THE ROLLERS OF A ROLL STAND - To accomplish the object of providing a method of and an apparatus for optimally cooling the rolls of a roll stand, where energy considerations, such as the minimization of necessary cooling fluid flow and cooling fluid pressure, and incident design and manufacturing costs, must be taken into account, the invention proposes that the rolls are cooled with a combination of high- and low-pressure cooling. | 02-09-2012 |
20120043048 | METAL-STRIP GUIDING APPARATUS - A continuous-casting unit produces a longitudinally extending and traveling strand having a solid shell and a liquid core. A strand-guiding apparatus has a plurality of longitudinally spaced section frames and respective pairs of roller assemblies carried on the frames and transversely flanking and bearing transversely on the strand. Each pair forms a gap through which the strand passes, and each roller assembly is formed by two aligned subrollers. A respective center is provided bearing between the subrollers of each roller assembly and bracing inner ends of the respective subrollers transversely against the respective frame. Respective outer rollers at outer ends of the subrollers of each roller assembly brace the respective outer ends transversely against the respective frame. The subrollers are shaped or supported on the respective frame such that in an unloaded condition the gap is transversely narrower at the center bearing than at the outer bearing. | 02-23-2012 |
20120118526 | ENERGY RECOVERY IN HOT STRIP MILLS BY CONVERTING THE COOLING HEAT OF THE CONTINUOUS CASTING PLANT AND THE RESIDUAL HEAT OF SLABS AND COILS INTO ELECTRICAL ENERY OR OTHERWISE UTILIZING THE CAPTURED PROCESS HEAT - In hot strip plants, after casting, the residual heat of a partial quantity of the slabs has hitherto been used such that the slabs either are directly rolled or are placed warm or hot in the furnace. The remaining slabs normally cool after casting in a hall through which flows air and are stacked before their further transport. The same applies to the residual heat present in the coils after winding, which often cool in the coil-storage area in air. The cooling energy of the continuous-casting plant likewise escapes unused into the surroundings. In order to convert this unused solidification heat and residual heat into electric energy, it is proposed according to the invention that the slabs ( | 05-17-2012 |
