20080196236 | Compact Plant for Continuous Production of Bars and/or Profiles - Compact plant for making steel bars and profiles with which, starting from the scrap, it is possible to obtain the finished product, for example bars with commercial length from 6 to 18 meters, pre-packed, packaged and ready for sale, with all the stations placed in line and operating continuously. All the stations are arranged in reduced spaces, thereby reducing both investment costs and plant management costs, and decreasing production times. Advantageously, the plant of the invention incorporates an extremely compact bar packaging apparatus which, through an innovative arrangement and innovative operating method of the components thereof, allows a further reduction in length. | 08-21-2008 |
20080251232 | Process and Plant For Producing Metal Strip - Process and ultracompact plant for continuous production of hot rolled steel strip comprising an ingot mould ( | 10-16-2008 |
20080257524 | Delivery Device and Method for Using the Same - Discharge device for discharging liquid steel into a roller crystallizer for the continuous casting of thin strip capable of reducing turbulence at the meniscus to a minimum so as to eliminate the relative defects on the cast strip by passing the steel between two crystallizer rollers. A relative casting process is also described, said process providing for particular expedients for improving the steel feeding from the tundish to the crystallizer. Advantageously, the feeding of guided steel jet streams inside the nozzle, or delivery nozzle, eliminates the disturbance at the meniscus caused by the air bubbles which form when free-falling jet streams come into contact with the air, as occurs in the known devices and plants. | 10-23-2008 |
20080271872 | Ingot Mold for Casting Slabs - Ingot mold for casting ultra thin slabs to be used, for instance, in a manufacturing plant for the manufacture of metal strips, having two wide concave walls ( | 11-06-2008 |
20080295990 | Oscillating Table - Oscillating table in which the oscillation drive, comprising a hydraulic actuator, transmits the oscillating motion to the mould via a spring subject to bending stress, for example a fitted rod. The body of the hydraulic actuator is also anchored to the floor by means of a fitted spring subjected to bending stress. Thus thanks to the absence of any mechanical bearings in the drive mechanism, all disadvantageous movements caused as a result of bearing play, which increases at high oscillation frequencies, are eliminated. Moreover, the use of mould guide elements having a much simpler design and consisting of straightforward bars, also ensures greater guidance precision and enables a reduction in the oscillation marks on the cast product, a reduction that is even more noticeable when working at higher oscillation frequencies. Advantageously, the presence of an anti-roll device, consisting of two or more pairs of bars, for example two pairs, ensures good torsional rigidity of the table. | 12-04-2008 |
20090014147 | Crystalliser Holding Device - Crystalliser holding device for billets, blooms and slabs production plants that has a high constructive simplicity, a significantly reduced overall weight and that reduces substantially to zero the need for maintenance. The crystalliser holding device of the invention, in addition to efficaciously guaranteeing the transfer toward the exterior of the heat of the liquid steel introduced into the tubular crystalliser contained therein, also provides a separate circuit for cooling the continuous ingot exiting the crystalliser and the rollers at the foot. It also permits an easy and rapid replacement in the oscillating table in which it is housed. | 01-15-2009 |

20090020258 | PLANT FOR PRODUCING METAL STRIP - Plant for the continuous casting of thick slabs, blooms or other similar steel products comprising an ingot mould and a series of containment and guiding rollers placed in the area below the ingot mould on both sides of the cast product, i.e. on the intrados and extrados, respectively. The rollers are arranged on at least three longitudinal rows and all have an axial length shorter that the width of the cast product. The rollers of a central longitudinal row are advantageously staggered with respect to the lateral longitudinal row rollers in such a way as to reduce the surface of the bulges created due to the ferrostatic pressure existing in the liquid core of the product at ingot mould outlet. Furthermore, the pitch between the adjacent rollers is advantageously always of different values so as to not cause the buckling of the bulges with a single frequency. | 01-22-2009 |
20090050287 | Oscillating Table - Oscillating table for blooms or billets production plants, comprising pairs of bars, lying on at least one horizontal plane, which constitute the elastic support elements of the crystalliser, thus permitting an optimal guidance of the oscillation thereof exclusively in the casting direction, said pairs of bars constituting a tie rod-strut system working in bending that confers to the table very high torsional and lateral stiffness. It allows a high precision in guiding crystalliser thus consenting it wide oscillations in the axial casting direction only. | 02-26-2009 |
