150 years of pioneering
Paul Wurth’s history is marked by more than 100 years of expertise in the design and manufacture of iron-making equipment. We have been integrated blast furnace plant builders for almost 70 years.
Like no other company in the field of iron making, we have been able to build on this foundation with our additional abilities, such as our knowledge and understanding of raw materials, process technology, and operations, control and automation, aspects of upstream and downstream processes, and environmental and emissions control. Continuous improvement and decades of R&D activities have led to innovative solutions for blast furnaces that improve safety, quality, sustainability, and customer benefits. This journey is continuing with our unique and complete range of solutions, technology, and equipment for blast furnace iron making under one roof – at Paul Wurth.

Blue blast furnace
Achieving important CO2 emission reductions in existing plants
Even before steelmaking customers opt for a complete changeover in technology, gradual and staged – though nevertheless substantial – reductions in the CO2 footprint can be reached in the short and medium term by retrofitting innovative, resource-saving solutions onto the existing installed equipment.
Currently, Paul Wurth is extending its offering of technologies designed to gradually reduce CO2 emissions in the classic blast furnace process, thereby creating a sensible balance between ambitious environmental targets and economic constraints. Our ‘blue’ blast furnace is capable of substantially reducing the carbon footprint of this established and proven technology.

Top charging
Top charging in ironmaking is revolutionized by our Paul Wurth Bell Less Top (BLT) technology, which enhances the efficiency and environmental performance of blast furnaces. The Paul Wurth BLT system precisely controls the distribution of raw materials like coke and sinter, ensuring optimal burden distribution and reducing fuel consumption. This innovative technology leads to significant CO2 emission reductions, improved productivity, and lower operating costs by supporting higher Pulverized Coal Injection (PCI) rates and minimizing coke usage. By integrating advanced process know-how and mathematical modeling, the Paul Wurth BLT system sets new standards in sustainable ironmaking, making it a game-changer in the industry.

Tapping
Stable and reproducible tapping operation
Stable and reproducible tapping operations are essential for reliable hot metal supply to a steelmaking plant, to ensure hot metal quality and to establish a smooth and efficient blast furnace iron-making process overall. Paul Wurth has extensive experience in the design of modern, highly functional cast houses – whether for new furnaces or for the modernization of existing plants.
For reliability reasons, Paul Wurth recommends world-class cast house machinery from TMT (Tapping Measuring Technology), a joint company of Dango & Dienenthal and Paul Wurth. TMT’s full range of proprietary cast-house equipment includes fully hydraulic taphole openers, clay guns, and runner cover manipulators as well as tilting runner drives, sampling and measuring devices, and auxiliary equipment.

Pulverized Coal Injection
Cost effective operation
The reliable, efficient, and accurate injection of auxiliary reducing agents is vital for cost-effective blast furnace operation.
Paul Wurth has been a driver of the pioneering development of Pulverized Coal Injection (PCI) technologies since the early 1980s; today, more than 80 mid-size and large blast furnaces worldwide operate with our PCI systems.
Paul Wurth’s PCI plants can support blast furnace operation with injection levels above the 250 kg/thm target. Simultaneously, development is focused on improving the combustion of the coal in the tuyeres/raceway area, which further enhances the customer’s gains in coke replacement.

Slag granulation
Value-added products from blast furnace slag
The Paul Wurth INBA slag granulation system is an advanced technology designed to transform slag into a valuable product for the cement industry. This process involves granulating the slag using water, followed by dewatering with the dynamic INBA dewatering drum. The system is highly flexible and compact, allowing it to be integrated seamlessly into various plant configurations.
Key benefits of the INBA system include reduced emissions and improved environmental control. Additionally, the system is recognized as a Best Available Technology due to its efficiency in processing slag and producing high-quality granulated blast furnace slag, which serves as a CO2-friendly substitute for clinker in cement production
