CIRCULAR LIFTING MAGNETS are extremely convenient and economical and find
wide application in handling different kinds of scrap such as pig-iron,
steel turnings, ingots, slab, cut-pieces of plates, channel beams etc.
Lifting capacity of the magnet depends upon the size of the magnet, power
rating, shape and size and typical bulk density of scrap material, amount of
the load in direct contact with pole faces, storage distribution and piling
of scrap, temperature of scrap material and above all the skills of the
crane-operator. To achieve optimum lifting capacity and the overall
efficiency of the magnet it is strongly recommended that the magnet is
allowed to properly rest on the scrap before switching 'ON' the magnet.
Lifting capacity of the magnet is strongly influenced by air gaps between
the loose pieces of scrap. Therefore, the Circular Lifting Magnets have
larger diameter to overcome the effect of air-gaps introduced by loose
scrap. Lifting capacity is also reduced drastically if the scrap material is
highly porous or it contains high percentage of carbon as the magnetic
property reduces due to high carbon content.
