At the same time‚ raw coal is processed to form coke in a coke plant and then sintered pellets along with coke are fed to a blast furnace. Hot metal is obtained at the bottom of the blast furnace above which slag floats‚ both of them are tapped out. Hot Iron metal is processed in LD1‚ LD2 and LD3 (Ladles) to lower down the carbon content

Redox reactions (Redox terminology‚ galvanic cells‚ standard electrode potentials‚ strength of oxidizing/reducing agents‚ corrosion and protection against it) Oxidation is defined as the loss of electrons and reduction is defined as the gain of electrons. Oxidizing agents‚ such as oxygen are defined as substances which accept electrons; reducing agents are substances which donate electrons. Redox reactions are: a) The reactions of metals with non-metals 2Na+Cl2→2Na+Cl- b) The reactions

frequently also as the final point to reject heat into the atmosphere by evaporating inside cooling towers. Depending on the quality of available fresh water supply‚ waterside problems develop in cooling water systems from: • Scaling • Corrosion • Dirt and dust accumulation • Biological growth Any of these problems – or more usually a combination of them – result in costly unscheduled downtime‚ reduced capacity‚ increased water usage‚ high operation and maintenance costs
