US 6,581,779 B2 · Method of the magnetic loading of a sintering material

Abstract

In a method of the magnetic loading of a sintering material, magnetically susceptible sinterable substances of high magnetization and fine substances of slidable dropping at low speed are segregated in great amounts in an upper portion of a sintering material layer deposited on a pallet. More of magnetically susceptible sinterable substances such as mill scale, returned ore and the like of good magnetic attachment and fine substances of low drop speed are caused to be segregated in the upper portion of that layer. A magnetic force is applied to a starting sintering material, during movement of the latter having been facilitated in its particle size segregation on a sloping chute, by means of a cylindrical magnetic drum having built therein a permanent magnet and disposed downwardly of the sloping chute.

A method of the magnetic loading of a sintering material wherein a starting sintering material is cut out of an ore supplying hopper by means of a drum feeder and is then charged onto a pallet mounted on a sintering apparatus of a Dwight-Lloyd type to thereby bring the starting sintering material into layered form on the pallet, the method comprising:

dropping said starting sintering material cut by the drum feeder out of a sloping chute of a plate type having a plurality of permanent magnets arrayed in a backwardly serially vertical posture;
causing magnetically susceptible sinterable substances present in said starting sintering material to be magnetically attached to the sloping chute;
and
then segregating the resultant sinterable substances, together with particulate substances present in said starting sintering material, in a lower portion of the sintering material layer, whereby said starting sintering material is loaded directly on the pallet from the sloping chute.

1 more element

applying a magnetic force to said starting sintering material having been cut through the drum feeder and being continuously flowed as said starting sintering material is slidably dropped out of a tip of a sloping chute of a plate type onto the pallet, the magnetic force being generated by a cylindrical magnetic drum located downwardly of the sloping chute;
and
causing magnetically susceptible sinterable substances present in said starting sintering material to be magnetically attracted toward and attached to a lower portion of the sintering material layer, while segregating particulate substances of low drop speed present in said starting sintering material in that lower portion, whereby both said magnetically susceptible sinterable substances and said particulate substances of low drop speed are segregated in large amounts in an upper portion of the sintering material layer on the pallet by inverting said starting sintering material when it is loaded on the pallet with use of the magnetic drum.
