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 |
20100116456 | PROCESS AND A PLANT FOR THE PRODUCTION OF METAL STRIP - A process and an ultracompact plant for the endless production of hot rolled steel strip comprising an ingot mould ( | 05-13-2010 |
20120234649 | DEVICE AND METHOD FOR FEEDING METAL MATERIAL INTO A MELTING PLANT - Device for feeding metal into melting plant, in particular into melting furnace including hearth and lateral aperture. Device includes means to feed metal terminally associated with a connection conveyor including a loading plane and cooperating with translation and positioning means. Connection conveyor able to assume first position during continuous loading step, wherein its front terminal end is located substantially flush with the furnace internal wall through the aperture, to introduce metal inside the furnace; a second position distanced from the furnace wall during the step of tapping liquid metal from the furnace; and a third position while first loading the furnace, with the furnace switched off, wherein its loading plane front end is inside the furnace volume to be disposed in proximity to the distal internal wall opposite the furnace proximal internal wall, to unload and distribute a charge to cover at least part of the furnace bottom surface. | 09-20-2012 |
20130086964 | ZEROING SYSTEM OF A ROLLING STAND - A zeroing system of a rolling stand which allows to replace the working cylinders or rolls in a four-high rolling stand for hot rolling strips and to subsequently zero the rolling stand without removing the strip from between the rolls themselves during the step of rolling. Furthermore, the system of the invention allows to very rapidly and accurately carry out the zeroing operation, thus increasing the productivity in the entire production system. | 04-11-2013 |
20130139993 | CONTINUOUS CASTING DEVICE AND RELATIVE METHOD - A continuous casting device including at least a crystallizer suitable for casting a metal product, and a plurality of guide and containing segments with rolls, the function of which is to accompany the cast product exiting from the crystallizer. The device includes, an extension of or in an intermediate position to one or more of the guide and containing segments with rolls, one or more guide and containing segments of the mixed type with panels and rolls, each including one or more guide rolls disposed on at least one side of the product and insulated and/or reflecting and/or heated panels disposed on the opposite side of the product, so as to reduce the loss of temperature of the cast product in transit. | 06-06-2013 |
20130145807 | ROLLING METHOD FOR FLAT PRODUCTS AND RELATIVE ROLLING LINE - Rolling method for the production of flat products, such as metal strip, which provides a production step of a thin slab with a thickness comprised between 30 and 90 mm, preferably between 35 and 70 mm, a temperature maintenance and/or possible heating step of the slab to be sent for rolling, and a rolling step with multiple passes performed in a reversing rolling mill ( | 06-13-2013 |
20130160277 | Rolling line and relative method - A rolling line ( | 06-27-2013 |
20140034264 | ROLLING METHOD FOR STRIP AND CORRESPONDING ROLLING LINE - Rolling method for the production of flat products with low productivity, which comprises a continuous casting step at a speed comprised between 3.5 m/min and 6 m/min of a thin slab with a thickness comprised between 25 and 50 mm. It also comprises a roughing step to reduce the thickness in at least one roughing stand to a value comprised between 6 mm and 40 mm, and suitable for winding, a rapid heating step by means of induction in order to at least restore the temperature lost in the segment downstream of casting and in the roughing step, a winding/unwinding step in a winding/unwinding device with two mandrels. The method also comprises a rolling step in a rolling unit that consists of a single reversing stand of the Steckel type to roll the product unwound by the winding/unwinding device, which comprises at most five rolling passes, or four inversions, in order to obtain a final product with a thickness comprised between about 1.4 mm and 10 mm, preferably between about 1.4 mm and 8 mm, a cooling step and a step of winding the final product. | 02-06-2014 |
