New and sustainable: charged single use crucible I without clamping ring

The ongoing development of our products is a key component of our company philosophy. Your personal experiences of using our products have once again shown us how important it is for us to have two-way communication with you, our customers. The latest outcome is the new functionality of the charged single use crucible I. The clamping ring has been omitted from the single use crucible I: the cover is now securely sealed by a machine, protecting the Thermit® portion against unwanted access prior to the actual weld and guaranteeing increased process reliability during the welding operation.

The charged single use crucible I (without clamping ring) is an environmentally-friendly consumable which guarantees improved safety and process reliability with our customary excellent quality.

Delivery of the new charged single use crucible I will begin at the start of July 2016.  This replaces the previous single use crucible I with clamping ring.

The improved cover can be removed effortlessly and with no problems after welding or, for example, to add the filter socket. For this purpose, we recommend the crucible opener (item no. 257141) in addition to the conventional crow bar (item no. 250564). The two items can also be used in combination following welding to remove the crucible from the mould shoes and to remove the slag pan.

This avoids the issue of clamping rings lying around the construction site and the resultant unnecessary waste.

If you have any questions about the new charged single use crucible I, please contact your account manager in Sales, who will be happy to answer your questions.

Thermit® Plus+: greater flexibility, fewer welding defects

As a system supplier for aluminothermic welding, Elektro-Thermit GmbH & Co. KG produces and supplies all consumables required for the Thermit® welding procedures, including: flameproof casting moulds, reaction crucibles, machines and tools and the Thermit® portions which form the basis of our welding procedures. The Thermit® in the portions is composed of aluminium granules and iron oxide, which produces a strong exothermal reaction after initial ignition. The high heat of the reaction and the alloy elements included in the portion make it possible to produce liquid steel at up to 2,300°C without using external sources of energy, as a result of which the ends of rails can be welded together.

In the case of both standard quality rails and high-strength perlitic grades of rails, the properties of the rail material and of the Thermit® steel produced can lead to surface defects in the form of small cracks or nicks. These defects can ultimately lead to fractures in the weld. The harder and more brittle the material, the more sensitive the weld is to such issues.

Our research and development teams set themselves the task of examining the key factors responsible for this in minute detail in order to create a less sensitive Thermit® steel and thus a more reliable and robust solution. They made use of a novel alloy concept to develop the innovative Thermit® Plus+. The improved formulation gives significantly better ductility. This means that the weld has greater flexibility, thereby optimising the flexural strength. By creating an improved tolerance range in respect of surface defects, the susceptibility of the weld seam is minimised and the durability and lifetime of the weld is substantially increased. Thermit® Plus+ gives the steel exceptional ability to handle discontinuities in the surface, so minimising the potential for cracking. It also provides resistance against rolling contact fatigue, offering a sustainable and efficient response to the material characteristics of head-hardened grades of rail. Thermit® Plus+ is exclusively applicable to our single use crucible system.

 

TRAFFIC PROJECT

Tailor-made high-speed line

Between 23 April and 8 May 2016, Deutsche Bahn AG and stakeholders in the sector renewed the track bed on the line between Hanover and Kassel. This section of track experiences heavy use.

In the vicinity of Göttingen, it was necessary to take measurements to determine the stress equalisation over a distance of 30 kilometres. Together with its British affiliate company Thermit Welding (GB) Ltd, Elektro-Thermit GmbH & Co. KG carried out the measurements on the continuously welded track. Thanks to our special equipment Railscan and VERSE, our experts were able to determine the forces acting within the track non-destructively. In the case of positive measurement results, the rails can be used again immediately. Our measurement technicians can evaluate the results instantaneously, allowing a rapid and flexible response in the event of rail warping or other damage to the track. Our globally unique service for determining stress in the rails provides added safety for the track.

Do you have any questions about our products and services in the field of measurement technology? Our measurement technology team are on hand with the answers.

Training in the Ivory Coast

It is especially important for a global company like Elektro-Thermit GmbH & Co. KG to also be available locally to provide rapid, professional service. Technical consultation, initial and ongoing training – our service engineers enjoy an excellent reputation with our customers and are highly valued as partners.

At the end of April, staff from our Technical Service and Sales teams travelled to Abidjan in the Ivory Coast to train local welders from the company Sitarail in the SoW-5 welding process. This process, certified to DIN EN 14730-1, is characterised by outstanding robustness and durability, making it ideally suited to the weather conditions and geographical situation of the West African region. The process was implemented by the local track laying company with increasing success.

The successful completion of the training meant that the welders were able to apply the welding procedure in practice while complying with our safety standards. We are delighted to have been able to make a contribution to continuous track welding in the Ivory Coast by training the SoW-5 welders, thereby connecting the world.

If you have any questions about initial and ongoing training or about the SoW-5 welding process, please contact our colleagues in Technical Service and Sales.
