20120273157 | ROBOTIZED SYSTEM TO MANAGE THE POWDERS IN A CONTINUOUS CASTING PLANT FOR STEEL - A method to cover the exposures of a bath of molten steel by elements of casting powder in an ingot mold of a plant for the continuous casting of steel, including a step of subdividing the ingot mold into a desired number of zones, with each of which a covering movement is associated, the zones being determined and identified in a manner coordinated with the position of the snorkel and of the edge of the ingot mold, and a step of automated execution of one or more covering movements by elements of which the casting powder is distributed in a selected one of the zones, which movements, repeated in sequence according to a desired program, are selected from a group including pouring movements and throwing movements, at least on the basis of the reciprocal position of each of the zones and the snorkel. | 11-01-2012 |
20120303315 | Device for Measuring the Speed of Products in Movement, in Particular Metal Rolled Products in a Rolling Line, and Relative Method - Device for measuring speed of oblong products moving along feed direction and emitting radiations, in particular rolled metal products in rolling line, including two radiation sensors, disposed reciprocally at close distance respectively defining an optical observation window, at pre-arranged distance from each other. Each window covers the image of an advancing product determinate portion equal to relative window width, irrespective of portion's movements transverse to feed direction. Sensors observe the presented product portion, on each occasion, in correspondence with associated windows consecutively along feed direction, and measure continuously intensity of radiation from the product portion in correspondence with the windows. Electronic processing unit determines, by processing electric signals associated with detected radiation intensity and arriving from sensors, using algorithms based on the correlation principle, time taken by the product portion to transit from first window to second, successive window, and then, based on distance between windows, calculates product speed. | 11-29-2012 |
20130160509 | METHOD AND DEVICE TO CONTROL THE SECTION SIZES OF A ROLLED PRODUCT - A method controls the section sizes of a rolled product in a segment of a rolling line between at least two rolling stands, wherein each is provided with its own drive members, in which at least a detector located between the two rolling stands detects a characteristic size of the rolled product. A control unit compares the characteristic size of the rolled product with a reference size and acts on said drive members in order to hold the rolled product in an optimal drawing condition. The method comprises setting a predefined value of an electric quantity of at least one of the drive members, measuring the reference size, and verifying the characteristic size of the rolled product in transit. If a deviation is detected between the characteristic size and the reference size, returning the characteristic size of the rolled product to the reference size. | 06-27-2013 |
20150027186 | PLANT TO CONTROL THE SECTION AREA OF A ROLLED PRODUCT AND CORRESPONDING METHOD - A plant to control the section of a rolled product passing through a rolling train comprises at least two rolling stands, at least a section area measurer disposed immediately at exit from at least one of the stands located downstream of the first stand, a control unit comprising a database, in which at least the parameters relating to the expected value of the section of the rolled product at exit from each stand are memorized, means to compare the values detected by the section area measurer with the values memorized in the database and means to act on the rolling parameters according to said values detected. | 01-29-2015 |
20150030049 | METHOD FOR MANAGING THE CHARGE IN A MELTING FURNACE AND CORRESPONDING LOADING APPARATUS - Method for managing the metal charge in a melting furnace comprising at least a step of depositing metal materials to be melted in a storage zone, a step of picking up and loading the metal materials from the storage zone onto feed means by means of loading means, and a feed step in which the feed means feed the materials toward the melting furnace. The deposit step provides to divide the storage zone into a plurality of specialized areas in each of which a differentiated type of the metal materials is deposited, and during the pick-up and loading step, a processing device controls and commands the actuation of the loading means which pick up the types of materials from the specialized areas and load them onto the feed means according to a desired modality and quantity. | 01-29-2015 |
