16-10-2020· If the iron is not held at the high temperature, but is allowed to cool slowly in the air, it is said to be normalized (this process, normalization, is a subset of annealing).As with full annealing, the heating process works out all of the little strains in metal (heats for this process range from 700 to 900°C), but by cooling it slowly afterwards (rather than holding it at a high temperature ...
Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.

Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal (called the "case") at the surface. For iron or steel with low carbon content, which has poor to no hardenability of its own, the case-hardening process involves infusing additional carbon or nitrogen ...
09-11-2002· Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

Iron ore pellets on a grid in a treatment chamber are hardened by contact with a heat treated, low calorific gas. The gas is generated in the gasification chamber of a slag bath generator. The generator receives a gasification agent and solid fuel that preferably further includes sulfur-binding materials, such as dolomite for generating a stream of low calorific gas.

iron ore crushing process before crusher hardening. This iron cylinder is picked up and dropped onto the ore, much in the manner of the old time stamp mills. This method seems to be popular in Australia. A more expensive but certainly faster and easier method is to use a small jaw crusher, such as is used in preparing samples for assaying.
