Methodology of Process The process is lead in a great container of steel, in format ovide, coated with clay or dolomita Its capacity goes of 8 the 30 tons of casting iron, being the typical load of about 15 tons. In the top of the container an opening, generally inclined exists for the relative side to its body, by which the iron is introduced and the end item, removed. In deep its some perforations, called tuyeres exist, by which air is forced for inside of the container. The converter is pivotado by trunnions, of form it to be able to be rotacionado to receive the load, turned to the normal position during the conversion and rotacionado to unload the casting steel to the end of the process again. The oxidation process removes impurities such as Silicon (Itself), Manganese (Mn) and Carbon (c), in the form of gaseous oxides or solid slags. The refractory covering of the container also has a paper in the process: The clay covering he is used in the acid process of Bessemer, in which it has little match in the raw material. When the match text is high, uses the basic process of Bessemer: The covering in this in case that it is of dolomita.
To give desired properties to the steel, other substances can after be added to the casting mass the complete conversion. The process Bessemer marked a revolution in the way to produce steel, therefore it allowed the steel production on a large scale, if becoming one of the bases of the Industrial Revolution. Before its process, the steel had a high price and in its place it was used pudlado iron. After the invention of Bessemer, the steel and the pudlado iron had been with similar prices, and, for comparison of properties, the industries had given preference to the steel.
