摘要： An electromagnetic lifter includes at least two polar expansions shaped for transporting a horizontal axis coil of hot-rolled steel. The polar expansions are connected through a ferromagnetic circuit and respective cores around which solenoids are arranged. A detection coil is arranged around each of the cores suitable to detect the change in the flux linked to the coil, and a control unit connected to the detection coils compares the values detected by each of them in order to authorize or not the transport. The relevant operating method includes a first check that the difference between the values detected by the two detection coils is below a preset threshold, and in the affirmative a second check that the overall decrease in the linked flux is below a second preset threshold, the issuance of an authorization signal to the transport being possible only in case of positive outcome of both checks.

摘要： A magnetic separator with permanent magnets includes a ferromagnetic member (2) for the circuit connection between at least two magnetic poles (3C) made up of ferrite magnets (12) in the bottom portion in contact with said ferromagnetic member (2) for the circuit connection, and of rare earth magnets (13) in the top portion that represents the entrance/exit surface (14) of the magnetic flux lines (15, 16). The ratio between the effective magnetic length of the ferrite magnets (12) and of the rare earth magnets (13) is preferably 2:1, and the preferred materials are strontium ferrite for the former and iron-boron-neodymium for the latter. In this way it is possible to combine the magnetic characteristics of the two types of permanent magnets so as to make them complementary and thus enhance the attractive effectiveness of the separator both for ferromagnetic materials with high or low shape factor, and for materials with high or low and sometimes very low permeability.

摘要： A novel electromagnet for moving tubular members is described, in which the flux lines extend only downwards in the direction of the load whereas the laterally dispersed magnetic field is substantially absent. The polar yoke of such an electromagnet has two North polarity cores on which two solenoids are wound, protected on the bottom by annular baffles made from non-magnetic material, and side panels made from ferromagnetic material extend along both sides and pass next to the two cores magnetically connecting the three South polarity poles, the side panels being magnetically insulated from the two cores. The thickness of the side panels is sized such that they are suitable to short-circuit the whole lateral flux preventing the dispersion thereof and conveying it completely towards the polar shoes of the three poles and into the material to be magnetized thus actively contributing to the lifting of the latter.

摘要： A magnetic lifter includes at least one dipolar mobile pole (1) consisting of two ferromagnetic pole pieces (2, 3), joined through an elastic connection, and inserted between two fixed opposite polarities (5, 6) of an electromagnet (7) so as to be able to slide within a housing (8) formed therebetween. By using as mobile poles (1) dipoles which slide between two poles (5, 6) of opposite polarity the closure of the magnetic circuit occurs within the single mobile pole (1) whereby the contact losses are reduced to half and it is possible to lift even small- and medium-sized loads with the greatest ease. Moreover, thanks to the elastic connection between the two pole pieces (2, 3) which allows a change in their mutual distance, upon activation of the lifter the two pole pieces (2, 3) tend to move away from each other until they adhere through magnetic attraction each one to its own adjacent polarity, thus canceling the air gaps and the consequent leaks as well as the risks of sliding.

摘要： A magnetic separator conventionally includes a conveyor belt (1) that forms a closed loop around a magnetic roller (2) and an idler roller (3) to convey a mix of materials (4), the novel aspect being that the belt (1) is not driven by the roller (2) but by the idler roller (3) that is motorized, and in that the belt (1) is not wound directly on the roller (2) but on an idle tube (3′) of non-magnetic material inside which the roller (2) is arranged with a minimum gap. It is therefore possible to obtain two surfaces with a relative slip and therefore two different speeds whereby the attracted material, during the path defined by the 180° of tangency to the magnetic area, due to the backing or advancing of the magnetic polarities tends to rotate backward or forward with respect to the travel direction of the belt. This results in substantially all the inert material being released and falling by gravity in a first fall area (5) located below the vertical tangent to the belt (1), and also in a progressive release of materials with increasing permeability, with a fan-like detachment that leads them to fall into distinct fall areas (6, 7, 8).

摘要： An electromagnetic lifter comprises at least two polar expansions (4), shaped for transporting a horizontal axis coil or the like, arranged perpendicularly to the axis of the coil to be lifted, divided into two halves (4a, 4b) slidable with respect to each other under the action of an actuator mechanism (5) and shaped so as to be able to penetrate each other. The adjustability of the polar expansions (4) allows them to better adapt to the different diameters of the coils to be lifted, with the result of exploiting the greatest possible useful polar section and of reducing to a minimum the operational air gaps, whereby the lifter need not be oversized to take into account the most unfavourable case and it results smaller, lighter and cheaper.
