Traveling Grate Sinter Plant Outotec

The Outotec traveling grate sintering process begins with the preparation of a raw mix of iron ores, fluxes, in-plant dust and spillage fines, solid fuel, and return fines. Water is added to the raw mix to obtain optimum permeability for lower electricity consumption, maintained by conveying the raw mix carefully onto the sinter machine.

Iron Ore Sintering Process Model to Study Local

The iron ore sintering process prepares fine iron ore for the blast furnace process. A mixture consisting of iron ore, coke (fuel) and additives is ignited at the top and air is sucked from below to move a combustion front down through the bed. Most of the sintering plants use permeability bars to raise the productivity. The permeability bars locally aerate the bed of raw materials after charging.

Magnet Manufacturing Process How Are Magnets Made

In this process, a suitable composition is pulverized into fine powder, compacted and heated to cause densification via "liquid phase sintering". Therefore, these magnets are most often called sintered magnets. Ferrite, Samarium Cobalt and neodymium-iron-boron magnets are all made by this method. Unlike ferrite, which is a ceramic material, all of the rare earth magnets are metal alloys.
