With its headquarters based in Chiswick, London, Primetals Technologies brings together the global expertise of the metals divisions of the parent companies Mitsubishi Heavy Industries and Siemens. With around 9,000 employees across the world, the task of welding the two entities into one has fallen on one of MHI’s most experienced engineers, Yasukuni Yamasaki, who has been appointed CEO and Chairman of the Board. In the following interview, Yamasaki explains the aims and scope of the joint venture. The interview was conducted by Dr. Tim Smith, a metallurgist by training and now an independent consulting editor for the steel and aluminum industries.
Post-merger integration following the joint venture is a priority. Synergies will be targeted so that by working together we can improve operating efficiency. Transparency in operation is an important factor. Combining the operation of a Japanese company with that of a European one can lead to a concerted effort to the benefit of our customers. The two cultures will complement one another in the global network in which we work with customers who themselves have a range of cultures.
I have already visited a number of customers in Europe, the United States, Japan, and other parts of Asia. So far, all have responded positively to the joint venture. They see the different cultures between the two organizations as a benefit to meeting their specific needs at their individual locations.
India has considerable potential for growth with a population close to that of China, but with a steel output of only about one-tenth of China’s. The economic model of India is very different from the Chinese system, but the growth rate is comparable. The Indian government has plans to make major improvements in infrastructure, a fundamental requirement of which is steel. Other regions of importance are the Middle East and North Africa. Greenfield plants in Europe, the United States and Japan are unlikely, but the growing demand for high-grade steels from these three regions will require revamping of existing equipment.
In these regions there is growing demand to save energy and meet increasingly stringent environmental limitations, which requires upgrading and renewing plant equipment. There is also a need to improve plants for downstream processing as more high-quality and high-strength steels are demanded. New technologies are required to meet some of these demands both upstream and downstream of steel production.
Primetals Technologies has the technology to deliver complete solution packages. For the minimill, we can provide everything from the electric arc furnace, casting and rolling technologies all the way to finishing for both long and flat products. Innovative technologies are also available such as nonstop rolling to rod in which hot billets are welded tail to head for continuous entry into the mill. This is more cost-effective than traditional interrupted processes. However, for small tonnages or frequent changes in grade and size, sometimes a batch process is more feasible. For minimills rolling flat products, direct linking of the caster to the strip mill is commercially viable. Primetals Technologies already has such technologies in its portfolio that includes the Arvedi ESP process as well as the Mitsubishi endless and semi-endless inline rolling of thin slab. These technologies provide smaller physical footprints than conventional casters and mills, and they can save as much as 40% in energy. A twin-drum strip caster is also part of the product portfolio of Primetals Technologies.
We see a growing market for new equipment to increase the output of flat products in Turkey, and we have received inquiries for this. In Germany, the demand is for upgrading existing plants to improve product quality, reduce energy requirements and increase automation.
Electric arc furnaces and the use of DRI can reduce the carbon footprint. The Quantum EAF with a scrap preheater shaft, for example, can provide a 30% reduction in CO₂ emissions. Such a furnace is being paired with the Arvedi ESP inline casting and rolling plant, which itself can lower energy consumption by 40%. These technologies are aimed at the minimill steelmaker rather than integrated mills where the high investment costs of installed plants make replacements difficult.
Yes, if a steelmaker requests joint development of a technology, we are willing to embark on joint-venture projects. Finex and Arvedi ESP are examples where this has already happened successfully with both technologies now being sold to other steelmakers.
I do not expect shale gas to have a major influence on steelmaking technologies in Europe. For the integrated mill, productivity can be increased by charging pre-reduced iron, which lowers CO₂ emissions per ton of iron output. The DRI for this application does not require the low gangue ores needed for an EAF, as there are fewer regulations limiting the amount of slag formed. The plant now being supplied by Primetals Technologies in Texas makes use of the low-cost shale gas presently exploited in the U.S. and will produce hot-briquetted DRI (HBI) suitable for shipment to Europe or elsewhere as a blast furnace feed.
The Arvedi ESP process can readily produce thin hot band rolled to as little as 0.8 mm gauge and even thinner. This can replace cold-rolled and annealed material for these gauges at much lower processing costs.
Customers increasingly want a complete lifecycle service, which we can provide. Outsourcing of such functions is now common in the United States and in Europe. On top of routine maintenance, Primetals Technologies can upgrade plant automation to maintain the plant working at optimum efficiency. This service is also offered for third-party equipment.
There is little overlap in the portfolios of the two joint-venture companies. MHMM had, for example, no caster technology comparable to that of Siemens VAI. MHMM brings particular expertise in the hot-strip mill, such as the Pair Cross Mill stand for strip crown and flatness control, and the sizing press to minimize caster mold changes. The joint venture has enlarged the portfolio that can now be offered to customers.
We do offer many technologies for long products, including head-hardened rails for railways, endless bar rolling mills as previously mentioned, beam mills and plate mills.
Yes. Rolling mills for aluminum and copper foil are already part of the technologies offered and forecasts indicate an increasing demand for aluminum sheet for the automotive sector.
The metals business is very complicated and draws on a mixture of technologies. A young graduate engineer may take ten years working in a company to fully learn the trade, and a further ten years to gain the mechanical, electrical and automation experience. After that, the person is ready to negotiate with customers. Managerial skills must also be fully developed before senior positions of responsibility can be undertaken. Every employee should have a passion to work in this field. I definitely have passion for the metals business and would like to work as long as possible.
