20th International Forgemasters Meeting - IFM 2017

Extrusion tools, such as containers and stems, are expensive components and it is important to use the most suitable materials to gain a long service life. However, it has to be pointed out, that not only the applied materials determine the life time of these tools, but also melting and forging techniques, as well as heat treatment have an essential impact. Since many years, Bohler Special...

Offshore structure is the large installation to facilitate drilling, refining, saving, and producing oil and gas. Hence, offshore structure should maintain long term safety of structure against severe external environments such as storm waves and low temperature. Therefore, heavy thick steel plates required with high strength and toughness in low temperature have been needed as the engineering...

Our company always works on changing the casting to the forging. Particularly, we produce forging valves for thermal power generation. The materials support with low alloy steel, high Cr steel, stainless steel to a thermal condition widely. From the situation in the world, the demand for the thermal power generation increases recently. About the materials such as turbine casings, upsizing...

Danieli Breda (DB) is one of his own business units, based in Milan, Italy, for over 50 years has been a leading in design, manufacture and supply of integrated plants for processing ferrous and non-ferrous metals in open die forging. In 2015 Danieli Breda started complete integrated Open Die Forging plant to produce rough axles for Railways. The Forging Complex, based on a high dynamic PFC...

In terms of increasing power demand in the world and a problem of global warming, high-efficient thermal power plant has been desired. A rise in steam temperature is an effective way for improvement of power generation efficiency, therefore a number of high temperature materials and components for USC/A-USC pressure turbine have been developed for many years. JSW began manufacturing...

It was described the development necessity of complete equipment for large forging hydraulic press. The general scheme of complete equipment consisting of 125MN double column open-die forging hydraulic press, and 1800kN/4000kN-m rail bound forging manipulator was proposed. A series of advanced design methods and key technologies were presented, such as digital prototype, co-simulation, visual...

The mono-bloc nozzle shell for CAP1400 RPV is a combined component of Vessel flange，Nozzle shell course, inlet and outlet nozzles, safety injection nozzles. The mono-bloc nozzle shell manufacturing is technically challenging for hot working technique due to its complex shape and large size. In order to realize the dream of eliminating both U-shaped and circular welding seams, a series of...

This paper focuses on the extent to which modernization and technological advancement have been a crucial support for CHW Forge in its efforts to embrace modern forging techniques and compete at a global level. The demand of high quality forgings in India introduced us to a newly formed niche market where factors such as quality assurance, customer service and comprehensive...

It has been widely focused because of its complex integral-structure and strict technical requirement since AP1000 main pipe appeared, which is made by 316LN stainless steel. After ten years of effort and exploring, excellent forging suppliers from all over the world agree that 316LN heavy forgings including AP1000 only can be formed by relatively simple solid forging technology though it...

The application of ultra high strength steels and advanced high strength steels at automobile industry is currently increasing for weight reduction and crash safety. The growing use of HSS results in decreasing tool life and productivity in manufacturing. The aim of this study is a development of high performance tool steel in hot work. Both the durability and high thermal conductivity are...

Current requirements for internal combustion engines are becoming more and more demanding. Therefore, new generation of crankshafts needs to reduce in size and sustain higher loads. This dramatically increases the stresses in the components, making the fatigue strength enhancement a necessity. Sidenor understands that this improvement should arrive as a result of the combination of two...

Recently, the needs for eco-ships have been increasing from the viewpoint of the strengthened environmental regulations and the demands for improvement of fuel consumption. The engine design places importance on higher power in low revolution range, so that the stroke of engine becomes longer. As a result, the higher torsional vibration is subjected to the intermediate shafts. The torsional...

Ellwood Crankshaft Group (ECG), one of the world’s largest producers of industrial crankshafts, has invested in a modern horizontal multi-directional press to complement the CGF Loewy Press originally built in 1960. This new facility will produce monolithic medium speed engine crankshafts, industrial crankshafts, and a multitude of none crankshaft geometries. The new 310MN press operations...
