摘要： A bar speed changing device (48) comprising a pair of upper rollers (55, 55′) and a pair of lower rollers (59, 59′). Said device receives a bar section with the rollers (55, 55′, 59, 59′) in the open position and rotating at a given speed. Upon leaving the device (48) said sections are fed into axially arranged peripheral seats (58) of rotating drum channels. Control devices calculate the speed at which the bar section must be released, upon completion of the braking action, according to the position that said section must occupy in one of said seats and on the basis of the bar-seat friction coefficient. When the rollers (55, 55′, 59, 59′) receive the bar, they turn at the calculated release speed. At a predefined moment, such to enable braking in the correct space and time, the four rollers close on the section and exert the braking action, exploiting the dynamic friction between the roller-section.

摘要： A rolling mill stand and related rolling mill for rolling rod-shaped bodies, even large in size, which meets the requirement of stiffness uniformity of the rolling mill stands in the transversal direction, all the hydraulic capsules being firmly fixed to the external structure of the rolling mill and providing for the side change of the rolls of each stand. The arrangement of rolling rolls and related extensions of each rolling mill stand is such to avoid problems of corrosion and damaging to the extensions themselves and to the reducers due to the drainage of the cooling waters.

摘要： 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.
