Arkansas Steel Mill Prevents Rust with HTHV Technology
Big River Steel started in 2014 in an area of northeast Arkansas that has been called “steel mill heaven.”
When it comes to steel mills, it’s hard to imagine the need for mechanical HVAC equipment to provide heat for the facility. The electric arc furnace used in the Melt Shop at Big River Steel exemplifies how unnecessary additional heat can be in an environment that already has plenty.
But there is more to the mill than just the Melt Shop. Before a 50,000 lb. roll of high-quality Big River Steel leaves the plant, it has to pass through the Finishing Mill. In this facility, massive rolls of steel can be pickled, galvanized, or annealed. The need for mechanical heat becomes critical: as these rolls of steel are waiting to be processed, they are susceptible to environmental conditions that create rust.
If the temperature inside the Finishing Mill falls below the dew point temperature, flash rusting of the rolls of steel can occur within a 24-hour time frame. In the worst case scenario, rusting can cause revenue loss for Big River Steel if they have to scrap the steel altogether.
That’s where the Cambridge Engineering High Temperature Heating and Ventilation (HTHV) technology helps save the day. The HTHV units in the Finishing Mill protect the coiled steel, working to keep the air warm, dry, and above the dew point in order to prevent moisture from forming on the rolls. When you have millions of dollars in inventory waiting to ship to your customer, you want to make sure they receive the high-quality steel they have come to expect from Big River Steel, according to Bryan Tidwell of Big River Steel.
Ever since the plant opened several years ago, Big River Steel has been using HTHV technology to help prevent the loss of inventory within the Finishing Mill. When they decided to add an additional 80,000 SF onto the Finishing Mill, they didn’t consider anything but HTHV technology to continue to keep their inventory rust free.
To date, the Finishing Mill at Big River Steel uses a total of (10) S-2200 HTHV units to keep the steel inventory safe from rusting. HTHV technology also helps keep the facility warm for the employees on cold winter days as well.
- Improved air temperature uniformity due to superior destratification without supplemental fans
- Improved indoor air quality due to use of 100% outside air
- 92% ultra-high efficiency resulting in energy savings and better indoor comfort
Whether it’s controlling the dew point or heating high bay buildings, HTHV technology is the most energy efficient solution for these types of structures. To learn more about the energy efficiency and destratification of HTHV technology, click here.
