Flexibility with CONPRO

New technology

In view of the expected rising costs for CO2 emissions, large price fluctuations of the charge materials for the BOF converter process and the increased scrap availability to be expected in the future, SMS group has developed a new primary smelter named CONPRO.

The CONPRO makes use of the proven BOF converter and electric arc furnace technologies, offering the most efficient and flexible combination of energy sources.

PEM – Primary energy melter

Reduced energy consumption
  • Reduced tapping times with separate boilers
  • Less impact on the power grid (less flickering)
  • Flexible use of primary energies such as oil, natural gas or process gas


  • Lower specific energy costs
  • Reduced primary energy consumption of up to 30 %


Modernizations lead to strong results

Conversions often have the aim of producing more steel in the same time. This is a clear competitive advantage, especially at times of high demand. But even when demand stagnates, the cost advantage per tonne offers you more flexibility and thus the security of always being able to serve the right market segments.

Tilt drive

A well-made tilt drive made in the SMS group workshop in Germany exceeds the basic function of just turning the vessel: It provides superior process control, reliability and maintainability.

P3S - Pneumatic slag stopper system

The pneumatic slag stopper plugs the tapping stream of the BOF converter by blowing inert gas into the tap hole at the end of steel tapping.

Bottom stirring

Bottom stirring with inert gas (Ar/N2) serves to improve the homogenization of the bath. The bath/slag reaction is enhanced and conditions close to the thermodynamic equilibrium can be reached.
