STEELMAKING

HIGH-PERFORMANCE SOLUTIONS FOR OPTIMIZED STEELMAKING ROUTES AND PLANT EQUIPMENT

In the metals market, steel-producing industries are facing rising energy costs and challenging market conditions while the demands put on product quality and process accuracy continue to grow.

Unisons International therefore focuses on process optimization – from individual plant design, including tried-and-tested technologies, up to sophisticated automation packages and sustainable solutions for offgas treatment and utilization. As the only global full-line provider and as developers of numerous innovative processes in steelmaking, Unisons International has the background, experience and expertise to advise producers on the optimum steelmaking route and plant equipment as well as supporting customers toward increasing the performance and flexibility of their plants.

CONVERTER CARBON STEELMAKING - BOOST YOUR COMPETITIVE EDGE WITH FULL-LINE SOLUTIONS FROM THE PROCESS INVENTOR

The demands placed on product quality, plant productivity and availability are on the rise. LD (BOF) plants lead the steel making sector in terms of reliability and economy.

When engineers in the early 1950s were looking for alternatives to the Siemens-Martin and Thomas steelmaking processes, they could not have imagined that they would initiate a revolution in steel manufacturing with the development of the Linz-Donawitz (LD) converter – also known as the Basic Oxygen Furnace (BOF). Today, around 70% of global steel production is based on this technology. More than 200 LD (BOF) plants – including numerous turnkey projects – have been planned, built, and commissioned.

CONVERTER STAINLESS STEELMAKING - INCREASED EFFICIENCY WITH SOLUTIONS FROM THE WORLD MARKET LEADER

Stainless steel production technologies – from scrap preparation to the finished product. Our expertise as the world leader in stainless steel making technology supports producers to boost their productivity and performance.

The demand for stainless steel increases each year, as well as the price pressure. Accordingly, plant operators must invest in process optimization and expand capacity to remain competitive on an international basis. Unisons offers its customers optimized solutions for increased productivity, improved plant availability, and full compliance with environmental regulations..

ELECTRIC STEELMAKING – A FULL ARRAY OF ADVANCED AND ENERGY-SAVING SOLUTIONS

Fine-tuning EAF technology to achieve an optimum balance of charge materials, process control, cycle times, logistics, and productivity requires both in-depth experience and a precise analysis of steelmaking requirements.

Sustainable steelmaking is in demand as never before. Challenging market conditions force producers who wish to remain competitive to raise the level of efficiency of their plants. Unisons International offers the right electric arc furnace to meet its customer's requirements. Plants are available that combine high capacity with maximum availability, process a variety of charging materials, and produce a wide range of steel grades without long adaption times that slow down production. At the same time, costs are reduced – both for initial investments and throughout a plant's operational plant lifetime – and the overal environmental impact of electric steelmaking is minimized.

SECONDARY METALLURGY - MAXIMUM EFFICIENCY, PRODUCTIVITY AND STEEL QUALITY WITH INNOVATIVE SOLUTIONS

Secondary metallurgy solutions from Unisons stands for fully integrated technology, mechanical engineering, automation and electrical engineering from a single source.

This is the basis for maximum plant availability, short charge-cycle times, low consumption values and top-quality treated steel. The result is high performance and productivity levels of both supplied and modernized plants combined with impressive cost savings in secondary metallurgy.

HOT METAL TREATMENT - CONTROL HOT METAL ANALYSIS TO ENSURE HIGHEST STEEL CLEANLINESS

Unisons offers all technologies and solutions for hot metal treatment to ensure constant low levels of steel impurities, like S, P to meet strictest quality requirements.

In order to maximize converter productivity and limit downstream refining costs, it is important to carefully prepare hot metal prior to the steelmaking phase. The solutions offered by Unisons include sulfur removal, silicon removal, phosphor removal, and other specialized processes to reduce contents of vanadium, chromium, titanium, and manganese.
