BLAST FURNACE SLAG, PROCESSING AND UTILIZATION
Abstract
During the pig iron technology process, by-products are generated along with pig iron production as a main product, having nature of secondary raw material and industrial waste. Blast furnace slag (hereinafter „BF slag“) ranks among the most frequent by-product generated within pig iron production process. Approx. 1,6 t of input raw material is required per a ton of produced pig iron; hereof approx. 330 kg of coke, 150 kg of dust coal and 900 m3 of hot air. Amount of generated BF slag refers to approx. 230-400 kg per a ton of pig iron. According to the Waste Catalogue (The Act No. 284/ 2001 Coll.) slag generated in the pig iron production process is classified in the category „Other Waste“. This waste category doesn´t impose a high environmental hazard with regard to its composition but excessive occurrence.
BF gas is generated through metal-bearing waste rock, flux and coke ash melting. BF slag chemical and mineralogy composition as well as physical-chemical properties predetermine it to utilization in various industrial branches. BF slag chemical composition and cooling-down method refer to the factors that significantly affect its further utilization possibilities. With regard to BF slag maximum utilization, it is therefore important to know slag types in detail beginning from slag generation, chemical and mineral composition up to physical properties that in combination with various processing methods can result in various final product properties. This document describes various methods of particular slag type processing at company Vulkmont, a.s.. The material deals in detail with technology provision of BF slag processing in the form of granulated BF slag, BF gravel and BF pumice as well as with possibilities of final products utilization.
Keywords: blast furnace slag|processing of slag|granulated blast furnace slag|blast furnace gravel and blast furnace pumice|utilization of blast furnace slag|
