Vesuvius has identified the practices within its operations that can directly or indirectly contribute to the United Nations Sustainability Goals (SDGs). We will focus our efforts on the following six SDGs where we believe we can make the most meaningful contribution.
The last couple of weeks have completely redefined the way we work and communicate. Online communication tools, including webinars, became extremely popular. They have transformed from a nice-to-have option to an indispensable tool - for us too. We have started a series of webinars for our non ferrous customers worldwide with more then 1000 registrations. More webinar sessions are going to follow soon. You can register for our two upcoming webinar topics below.
What is a webinar?
A webinar is an online seminar delivered via the internet. Typically, webinars are shared live, or in real-time, but they can also be recorded before being shared with audience members. Whether or not a webinar is live, it must include an interactive element that allows viewers to participate, ask questions, make comments, or collaborate with the presenters and/or hosts.
Filter Print Optimisation for Horizontally Moulded Iron Castings
To ensure the delivery of the cleanest, and least turbulent metal to the mould cavity, a correctly designed filter print and gating system must be used.
Qualitative and quantitative analyses using sophisticated casting process simulation software programs are important tools to enable detailed understanding of the performance of filters in various filter print designs.
This webinar will outline the results of recent studies undertaken and how these are used in the design of optimised filter prints.
In aluminium foundries, the use of insulating sleeves in a wide variety of materials has been common practice for many years. Foseco is now launching an exothermic sleeve material for aluminium casting applications for the first time. The new recipe FEEDEX NF1 was specially developed for the aluminium sector and adapted to the existing requirements there. It ignites quickly, the exothermic reaction takes place slowly and steadily and ensures a considerable improvement in the feeding effect. This results in only low emissions. FEEDEX NF1 feeders are available in numerous different versions and eliminate the need for manual addition of exothermic powders.
Molten aluminium is highly reactive and easily reduces water vapour to form aluminium oxide and hydrogen. The hydrogen then dissociates into its atomic form and then diffuses into the melt. This atomic hydrogen is readily taken into solution in the molten aluminium, however during solidification this results in a drastic reduction in solubility. The consequence of the hydrogen content in the melt being high is that the hydrogen becomes liberated during solidification to form very fine porosity throughout the casting. This porosity is not interconnected but will form points of weakness in the casting as well as becoming unsightly on machined surfaces. In this webinar we will show you how to reduce hydrogen efficiently with pumping rotors.
The types of casting being made today in aluminium foundries are very varied. Thinner and lighter castings are being expected to perform in more arduous conditions than ever before and sophisticated Aluminium alloys are being developed to raise their potential properties to new heights. With ever increasing demands being placed on the foundry, there is an increasing need to control the individual processes that are involved in making the casting. In this webinar we will show you how to reduce the oxide content in the melt with our user-friendly fluxes and how to stabilize your process sustainably.
Grain refinement is an essential part of the aluminium casting process with the aim of reducing the size of the primary aluminium grains during the solidification phase. This process has many advantages for most under- and eutectic aluminium alloys as it improves feeding, extension and mechanical properties, increases corrosion resistance to fatigue, improves machinability of the casting and reduces hot cracking. For many years grain refinement has been carried out with master alloys. In this webinar you will learn more about the use of chemical grain refiners and the technical differences between the two processes.
