Renuda Projects: Process Industry: Industrial Heat Transfer

Process Industry & Manufacturing Industrial Heat Transfer

ArcelorMittal manufactures beams for the construction industry at its Differdange site. They decided to use numerical simulation to evaluate how to reduce energy consumption and to understand how temperature non-uniformities occur within the Differdange furnace. During the transient calculations, the heat treatment of several hundred metric tonnes of beam blank was modelled.

Renuda won a competitive tender to model the heat transfer processes. After building a new CAD geometry of the domain, Renuda produced a rigorous analysis which took into account the complex combination of a large variety of:

I Physical phenomena

• time varying flow

• turbulence

• gaseous mixing

• combustion

• multi species flow (combustion products)

• radiation

• mesh motion

I Processes

• opening and closing of the furnace doors

• loading and unloading of the beam blanks

• beam blank motion

• motion of the mobile beam blank supports

• conjugate heat transfer

Renuda’s results showed that numerical simulations are capable of predicting the flow field in the furnace with a good degree of confidence in the results. On that basis, Renuda proposed two configurations to optimise the heat transfer processes and reduce losses.
