"Blast-furnace process is a set of great number of physical and chemical, thermal and mechanic actions. These actions do not take place separately, but they happen in a single time line and in specific mutual conjunctions. Blast-furnace batch consists of; above all, metal containing materials, slag-making additives and fuel. Blast-furnace batch often contains number of elements which, in a form of various compounds, disrupt the execution of chemical, physical and thermal processes during production of pig iron. The content of these negative elements represents a key factor, mainly in case of metal containing materials. Compounds causing erosion of blast-furnace lining and causing subsequent technological breakdowns are typical harmful substances of this type. Other substances deteriorate the properties of melt (viscosity, melting temperature) or they cause degradation of blast-furnace coke. These harmful substances included in batch raw materials, above all alkaline compounds and heavy metals, cause various technological troubles in sintering and blast-furnace processes. Alkaline substances cause higher reactivity of coke, premature mellowing of metalliferous batch, disintegration of sinter, they also take a share in creation of deposits in fire resistant blast-furnace lining and they accelerate its wear. Heavy metals have simile effects. These problems lead to higher consumption of coke and irregular runs of blast-furnaces. Material balance of harmful substances is used in metallurgy in order to refine and verify the values of emission factors, or to identify the distribution of undesirable substances in technological processes. The objective of this article is to compile material balances and distributions of the monitored harmful substances in production of pig iron for agglomeration and blast-furnaces."@en . .
