3.3 Raw Materials for Cement Manufacture

While it is important to have the correct proportions of calcium, silicon, aluminum, and iron, the overall chemical composition and structure of the individual raw ingredients can vary considerably. The reason for this is that at the very high temperatures in the kiln, many chemical components in the raw ingredients are burned off and replaced with oxygen from the air.

corrosion in cast iron = graphitisation Degremont

Water that has a low hydrogen sulphide content (1 ppm) also encourages graphitisation. Graphitisation tends to penetrate into the metal but at slow rates of progress.

Iron Simple English Wikipedia, the free encyclopedia

The blast furnace is filled with iron ore, coke and limestone. A very hot blast of air is blown in, where it causes the coke to burn. The extreme heat makes the carbon react with iron ore, taking off the oxygen from iron oxides, and making carbon dioxide. The carbon dioxide is a gas and it leaves the mix. There is some sand in with the iron.
