TWT FLUID TREATMENT FOR THE STEEL INDUSTRY
|Application||Triangular Wave Technical Benefits|
|Wastewater transfer lines||Deposit control in pipe lines.|
|Cooling process||Deposit control in cooling towers and cooling water transfer pipes.|
|Dust control and electrostatic precipitators||Deposit control on precipitator plates and water nozzles.|
|Rolling plants - cooling water and water to flush impurities||Deposit, biofilm, and bacteria control in pipe lines and roller channels|
|Rolling stock||Control scale deposits in the cooling systems and radiators of trucks, generators and locomotives|
|Typical equipment that will benefit from TWT systems||Boilers, heat exchangers, rollers, transfer lines, pumps, valves, rollers, condensers, and cooling towers|
|Steel plants use a tremendous
amount of water for waste transfer, cooling, and dust control. The plants
have sintering mills, coke plants, electricity and gas for furnaces,
chemical by-products and chemical processes, water cooled rolls, pumps,
slab furnaces, mandrels, extrusion equipment, waste water treatment,
transfer lines for sludges and slurries.
The steel industry is one of
the nine vital "Industries
of the Future" designated by The
US EPA Office of Industrial Technologies.
According to the OIT, these nine industries necessarily use large
amounts of heat and energy* to physically or chemically transform
materials. Collectively, they supply 90% of the materials vital to our
economy, produce $1 trillion in annual shipments, directly employ over 3
million people, and indirectly provide an additional 12 million jobs at
all skill levels.
The steel industry is vital to U.S. economic competitiveness and national security. It employs over 150,000 people in well-paying jobs and is among the most productive, efficient, and technologically sophisticated industries in the world. For example, many grades of steel in use today could not have been made even 10 years ago. Traditionally valued for its impressive strength, steel has also become the most recycled material, with 55 percent of U.S. steel now produced from scrap.
Since energy represents about 15 percent of the total manufacturing cost for steel, steelmakers are highly motivated to reduce energy intensity. The steel industry has made significant progress in reducing energy intensity, but still accounts for about 2% of all U.S. energy use. Since blast furnaces must reach temperatures of about 2,800° F, it is not surprising that ironmaking is the most energy-intensive part of the steelmaking process, accounting by itself for nearly 40% of the energy used in the process.
