Project Profile

Client: Severstal North America, Metal Industry Application: Flat Roll Steel MillLocation: Columbus, MS

Project OverviewThe Problem

The Plant was suffering from high temperatures in the caster area as a result of the heat collecting at the ceiling.

Severstal contacted Moffitt to figure out how to best relieve the heat from this space, without interfering with the work process or letting in rain or weather.

Project OverviewThe Problem

Before modifications the mill was dark, smoky and hot.

Project Overview

Moffitt utilized Computational Fluid Dynamics (CFD) in the design process for this project. This allowed Moffitt to design a sophisticated model of the building before any work was done.

CFD is a computer program that predicts air flows and transfers of energy within a building. This allows Moffitt to more accurately determine where the heat collects and how to best ventilate it from the building.

Project OverviewCFD

Heat rises from the work processes and collects at the ceiling.

Project OverviewCFD

A CFD thermal map allows the design team to analyze the movement of warm air at different levels of the building.

Project OverviewVisual Overview

Using CFD, Moffitt understood the amount of intake and outlet air required to reduce the temperatures in the mill and installed natural ventilation systems in key areas to improve the ventilation.

*Equipment provided and installed

Moffitt installed Labyrinth units running down slope to allow for the hot air to escape from the mill.

Project OverviewVisual Overview

Severstal wanted to take advantage of the maintenance and operating cost savings that a natural ventilation system provides.

Project OverviewVisual Overview

The Labyrinth units (show here from below) ventilate the hot air while also providing ample natural lighting.

Project OverviewVisual Overview

For this project, the goal was to reduce the temperature at the caster deck to bring it within 10 degrees of outdoor ambient conditions.

Project OverviewResults

Moffitt exceeded the project goals and dramatically improved operating conditions at the caster deck. The new ventilation system lowered the temperature to within 5 degrees of outdoor ambient.

Based on the success of this project, Severstalutilized Moffitt’s ventilation services for several other areas of the plant.

Project Overview

For this project Moffitt provided full turn-key services.

With design services from Moffitt Corporation, manufacturing from Moffitt Fan and installation provided by Moffitt Mechanical, Moffitt does it all.

Testimonial

“In my past 20 years of Steel Mill Construction and being around the Steel Mills I haven’t put in anything besides Moffitt Ventilators.” -Severstal Construction Manager, Jim Bell
