Up to 40%
of the overall steel production costs are spent on energy according to the World Steel Association.
With the steel markets being highly competitive cost-efficiency is one of the top priorities for plant managers. And as energy costs can constitute up to 40 % of the overall costs, energy consumption has a huge potential for cost optimization. Think for example of utilities, or “W.A.G.E.S.” (water, air, gas, electricity, steam). Utility costs in the steelmaking industry are equal to more than 3% of a plant’s revenue in the United States, and more than 6% of revenue in Europe.
To improve the performance of a blast furnace, a converter or an electric arc furnace, various critical parameters have to be closely monitored. Having reliable and accurate measurements ensures a tighter process control and by that an optimized energy usage. Also critical is the optimal usage of argon, compressed air or steam. As they have a direct impact on the result of the process they also influence how much energy is used.
Accurate measurement to improve process control
Successful management of utilities, or “W.A.G.E.S.” (water, air, gas, electricity, steam)
Typically, 10% of a plant’s electricity is consumed for making compressed air and 40% of its natural gas is used for making steam. Measuring “W.A.G.E.S.” is the foundation for any energy management plan. Energy management consists of measuring and collecting this data and analyzing the data for reporting. Based on the findings, appropriate actions can be taken in order to reduce utility consumption and costs.
Digital fieldbus networks connect field instruments to the control and maintenance systems. In combination with smart sensors featuring Heartbeat technology this enables instrument verification, advanced process diagnostics and condition monitoring functions. This gives managers an even greater control over their processes and helps them to make the right decisions to ensure efficiency and product quality.
