Flexibility in charge materials and low-emission production with CONPRO

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

No energy losses from power generation and transmission
  • Shorter tap-to-tap times with separated vessels
  • Less impact on electricity grid (less flicker)
  • Flexible use of primary energy e.g. oil, natural gas, or process gas

YOUR BENEFITS

  • 32 % lower overall primary energy consumption 
  • Lower specific energy costs

Technology

Modernizations to boost your utilization rate

All replacements and revamps in your converter steelworks pursue this central goal: the capacity to produce more steel in the same time in your existing factory. Achieving this aim means your steelworks can supply the market with higher capacities - at lower cost.

This creates clear competitive advantages for you, especially in times of high demand. Yet, even when demand stagnates or falls, the cost benefit per ton gives you more flexibility and therefore more security that you can always supply 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.
