Cast Manganese Products Modelling,<br />

Methods and Metallurgy<br />

3D modelling and FEA allow us to engineer all of our products more<br />

efficiently. From CNC controlled pattern making for cast manganese<br />

crossings (frogs) to Failure Mode and Effect Analysis (FMEA) to determine<br />

weaknesses in design<br />

Our current engineering processes revolve around 3D modelling to<br />

generate LEAN products with highly analysed performance characteristics<br />

3D modelling interfaces directly with our Computer Numerical Controlled<br />

(CNC) machines to offer a superior and repeatable quality product<br />

The casting process itself is a well established and highly controlled<br />

process. This control stems, in part, from 3D modelling the molten shape<br />

and the molten metal flow to ensure cooling rates and other parameters<br />

are within known tolerances to produce a high quality product<br />

Within our South Queensferry and Midland foundries we have qualified<br />

metallurgical engineers and are members of the Cast Metal Federation<br />

Complex Cast Manganese Solutions<br />

Our design engineers are qualified to high standards and are able to<br />

solve complex geometrical alignment problems facing many of the<br />

world’s railways<br />

We undertake work regularly for London Underground and have also<br />

worked for various subterranean rail systems around the world where<br />

alignment is paramount. We have been involved in tunnel wall studies<br />

and modelling train paths to ensure clearance is within permitted levels<br />

Geometrical data is used to develop 3D models of cast manganese<br />

products and these models are used to create the wooden patterns used<br />

in the production of sand moulds for the casting process<br />

Molten Metal Modelling using Magma 5 Software<br />

Using Magma 5 software we simulate mould filling, solidification and<br />

cooling rates for different shape and complexity patterns<br />

This state-of-the-art analysis tool ensures that the molten metal witnesses<br />

directional solidification in order to eliminate the formation of shrinkage<br />

cavities within the casting<br />

We are also able to simulate metal entering the mould cavity using<br />

particle tracers, which move just like metal flow, allowing the identification<br />

and elimination of high and low velocities during mould filling which can<br />

lead to the formation of casting defects , oxide films and inclusions<br />
