| 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 |
| 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 |
| 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 |
| 20090108692 | Laying Head with a Vibration Damping Device - A laying head for forming coils using continuous and substantially rectilinear rolled products such as rods or wire, having vibration damping means integrated in one of two rotor supports ( | 04-30-2009 |
| 20090121064 | Laying head with multi-groove rotating member - A laying head, for forming coils starting from continuous rolled products such as round bars or wire rods ( | 05-14-2009 |
| 20100300586 | PROCESS OF THERMAL TREATMENT OF RAILS AND DEVICE THEREOF - Process for the in-line thermal treatment of rolled rails which ensures to obtain a fine pearlitic structure which is uniform through a whole predetermined superficial thickness of the rail head. There is also disclosed a new device for the thermal treatment of rails in-line with a rolling system which, as compared to the known devices, is structurally much simpler, has a high sturdiness and requires less maintenance. | 12-02-2010 |
