BOF Calculator

A ready-to-use Converter Process Model which you can fully customize to your specific needs.
Implement your own statistical findings in the model and increase the hitting rate.


Limitless calculation options

The BOF Calculator can be adapted to your specific steel making practice.

1 Order calculation

Calculates the hot metal and scrap weight necessary for a predefined tapping weight and temperature.

2 Adjustment of coolants

Updates the required coolant weight for a predefined hot metal and target tapping temperature.

3 Heat calculation

Calculates the steel and slag analysis and the tapping temperature for a given charge material mix.

4 Slag conditioning

Finds the correct weights of slag builders (lime, dolo, etc.) to reach the required basicity, MgO content, and slag weight.

Open know-how

We don't hide what's underneath the hood. Access and review all implemented know-how of the process model.

Metallurgical equations

Use your own empirical functions (e.g., for the P distribution) without losing any functionality.

Customize yourself
