Iron Nugget

The projected growth in production of pig iron nuggets on the Iron Range of northeastern Minnesota provides new opportunities for marine transportation on the Great Lakes. The shipping of this higher-value commodity necessitates low freight rates and minimum inventory costs. This paper examines viable ship design concepts to provide competitive transportation solutions.

At Home

Situations of the CO2emission in steel industry at home and abroad are introduced in this paper firstly. Then CO2emission is calculated in the RHF—EAF flow for treating V-Ti magnetite according to data from the pilot plant in Pangang Group. Besides, CO2emission of the traditional BF process is calculated as well. The results show that CO2emission is 1427.3kg/t pig iron and 1508.7kg/t for the pilot and BF process, respectively. Otherwise, the difference between the two processes is analyzed and the prospect for the reduction of CO2emission in the iron and steel industry is proposed as well.

Plant Process

IronArc is a newly developed technology and an emerging future process for pig iron production. The long-term goal with this technology is to reduce the CO2 emissions and energy consumption compared to existing technologies. The production rate of this process is dependent on the stirring, which was investigated in the pilot plant process by measuring the mixing time in the slag bath. Moreover, slag investigations were done both based on light optical microscope studies as well as by Thermo-Calc calculations in order to determine the phases of the slag during operation. This was done because the viscosity (which is another important parameter) is dependent on the liquid and solid fractions of the slag. The overall results show that it was possible to determine the mixing time by means of the addition of a tracer (MnO2 powder) to the slag. The mixing time for the trials showed that the slag was homogenized after seconds. For two of the trials, homogenization had already been reached in the second sample after tracer addition, which means ≤8 s. The phase analysis from the slag indicated that the slag is in a liquid state during the operation of the process.

High Peak Temperature

An experimental device for plasma treatment of low and intermediate level radioactive waste was built and tested in several design variations. The laboratory device is designed with the intention to study the general effects and difficulties in a plasma incineration set-up for the further future development of a larger scale pilot plant. The key part of the device consists of a novel microwave plasma torch driven by 200 W electric power, and operating at atmospheric pressure. It is a specific design characteristic of the torch that a high peak temperature can be reached with a low power input compared to other plasma torches. Experiments have been carried out to analyze the effect of the plasma on materials typical for operational low-level wastes. In some preliminary cold tests the behavior of stable volatile species e. g., caesium was investigated by TXRF measurements of material collected from the oven walls and the filtered off-gas. The results help in improving and scaling up the existing design and in understanding the effects for a pilot plant, especially for the off-gas collection and treatment.
