  • Description: The main focus of the project was to reduce the coke consumption at the Blast furnace. This idea was approached on two different measures: One measure was to substitute coke by cold bonded carbon briquettes made of carbon materials which are usually not usable for the blast furnace. The aim was to broaden the reductant base. The properties of carbon materials as coke breeze and dust, anthracite, pet coke and charcoal were evaluated and recipes for carbon briquette making were developed which fulfill the requirements of a blast furnace coke. Based on the recipes a trial charge of 2000 t of carbon briquettes was produced and blast furnace trials were carried out to substitute coke by carbon briquettes was investigated. At operational BF trials 12% coke was substituted successfully by the carbon bricks at a constant production rate with an exchange factor of about 0.7. The second measure was to increase the reactivity of nut coke by activation agents as magnetite, hematite, lime and iron nitrate. The aim was to lower the thermal reserve zone temperature in the BF shaft. The investigations in lab-, pilot- and industrial scale have shown that the reactivity of nut coke is increased by the chosen agents. The influence of the activated nut coke on the thermal reserve zone was proved in operational BF-trials. The utilization of activated nut coke lead to a reduced coke consumption at the BF trials due to increased indirect reduction when it was charged to the ferrous layer.
