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.

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.
