Coke

  • Coke revenues up significantly by 188 per cent to EUR 303 million
  • 1.0Mt of coke produced
  • Production consolidated onto a single site
  • Refurbishment of existing battery complete
  • Additional new coking battery brought on-stream
  • Improved demand for steel drove up volumes and prices

Our coking subsidiary, OKK Koksovny, a.s. (‘OKK Koksovny’) is the largest producer of foundry coke in Europe, now operating from one site, Svoboda in Ostrava. OKK Koksovny produces both foundry and blast furnace coke from four batteries with a maximum capacity of 850kt per year, following the conclusion of the consolidation process.

Coke is produced by heating up coking coal in furnaces at temperatures of up to 1,200ºC without access to oxygen, to extract volatile components such as gases and produce a highly efficient, high carbon fuel. There are two types of coke: blast furnace coke which is used as a reducing agent in smelting iron ore to produce steel and foundry coke which is used to melt pig iron in the manufacture of iron castings by the iron founding industry.

It has been an outstanding year for OKK Koksovny as we completed the consolidation of production onto one site, built a new coking battery, and completely refurbished another whilst production continued. Health and safety remained our highest priority during this period of intense activity and we maintained our strong track record delivering a coking Lost Time Injury Frequency Rate LTIFR of 2.55 with only four registered accidents (2009: 2.39; four registered accidents).

In line with our strategy to enhance profitability by investing in equipment and technology, we successfully completed our Coking Plant Optimisation Programme 2010 (‘COP 2010’), which aimed to increase the efficiency and reduce the cost base of our coking operations by consolidating all operations at one site on time and to budget. Notably, we maintained high safety standards throughout the project.

A key achievement of COP 2010 was successfully consolidating all production at our Svoboda site. Shutting down the Jan Šverma site by the end of 2010 posed a significant environmental challenge as health and safety standards needed to be maintained whilst dealing with the gas and chemical outputs of the shut down process. Extensive consultation with the labour unions meant that approximately 50 per cent of the workforce at the Jan Šverma site was transferred to the Svoboda site and the remainder left the Company by mutual agreement.

We also constructed a new battery, one of the few coking batteries that have been built in the region recently, which will enable us to respond to the demand for foundry and blast furnace coke more flexibly. With 56 chambers and a maximum production capacity of 225kt per year, the new battery no. 10 has a state of the art device to capture the air pollutants generated during production, significantly reducing environmental impact. The new battery was slowly heated from June 2010, trial production started in October 2010 and moved into full production at the beginning of 2011.

A further phase of COP 2010 was the refurbishment of battery no. 8, prolonging its life for more than 20 years. This was a complex project as the chambers were refurbished in stages whilst the battery continued to operate.
