Pioneering Process Improvement in Iron & Steel

Sustainable competitive advantage is essential in today's dynamic Iron & Steel Industry.

Clyde Materials Handling provides a variety of technologies that directly enhance the iron & steel making process.

Whatever the application, Clyde Materials Handling is able to draw on expertise in pneumatic conveying and process injection and combine these with a deep understanding of their application to the Iron and Steel industry.

Blast Furnace Coal Injection

Today coal injection is an accepted and well-recognised practice to reduce reliance on metallurgical coke and reduce ironmaking costs.

25 years ago Clyde Materials Handling and Corus (formerly British Steel) pioneered the development of advanced coal injection into blast furnaces using Granular coal instead of the more traditional Pulverised coal.

The main advantages of Granular Coal Injection (GCI) are:

  • Reduced grinding costs
  • Reduced drying costs
  • Cheaper operating costs

Clyde Materials Handling and Corus now jointly promote blast furnace coal injection to other steelmakers all over the world. Clyde offer the injection systems with the blast furnace technical operating know-how offered by Corus.

We are the only company to be able to offer traditional Pulverised coal injection systems as well as the more advanced Granular coal injection systems.

The other major advantage of the systems we offer is the advanced injection technology used. Clyde materials handling has developed the most advanced Rotofeed and Rotoscrew injection technologies that enable a wide range of materials to be handled by the same piece of equipment i.e. Pulverised coal, Granular coal, illmenite, plastics, iron ore fines or any other dusts that are required to be injected into the furnace.

It is also enables high injection rate accuracy and tuyere to tuyere accuracy to be achieved, of +/-1% measured on a second to second basis. This level of accuracy is vital for good coal distribution around the furnace and for injection rates over 150 kg/thm.

With over 36 blast furnace references World-wide, blast furnace operators are enjoying real economic business benefits using Clyde materials Handling injection systems.

 

Alternative Iron Making

  • Taking the pioneering work that first applied materials injection to iron making, Clyde has transferred its technologies into the field of alternate iron making. Today, Clyde Materials Handling works with a number of recognised industry leaders including VAI, POSCO, HIsmelt. For each, Clyde Materials Handling has provided raw materials feed systems that combine accuracy and reliability to help in the stable production of consistently high quality metal. Clyde Materials Handling systems handle coal, ferrous fines, limestone, ore and additives.

Desulphurisation & Casting

  • Increased product quality by introducing additives to liquid metals
  • Enhanced casting operation by delivery of flux to the casting table
  • Additives to desulphurise and enhance the quality of liquid metal can also be delivered using Clyde Materials Handling's systems. Accurately injecting additives such as magnesium and limestone directly into hot metal ladles, the Clyde Materials Handling system can be fully integrated into the plant. The result is improved quality and casting performance without delaying production or major changes to plant layout.

Continuous Casting Flux Injection:

  • Developed to improve the continuous casting process, the Clyde Materials Handling flux injection system can be used to boost metal quality, smooth production and reduce costs. The system takes flux materials from a storage container and delivers it consistently and reliably to the casting table. This creates a stable level of flux above the molten steel and reduces breakouts, snagging and flux entrainment in metal. In turn this reduces the need to repair surface finish and reduces waste flux.

Off-Gas Dust Transfer

  • Hot and abrasive, the dust from gas cleaning plants can present a real challenge to traditional mechanical conveyors. Pneumatic conveying can offer a reliable alternative that is both economical to operate and completely enclosed.
