SiC Ceramic Foam Filter Effective In Foundry Technology Of Cast Iron

Industrial applications of filtration techniques have hugely improved in the last few decades or so. These are meant to make the work easier and increase productivity. In steel and iron industries, as well as in aluminium foundry, many industrial companies are using the SiC ceramic foam filter as it is having plenty of advantages and also because the ceramic filter for steel is quite resistant. Above all advantages, the one that marks the filtration process is supposed to give high quality cast iron in these industries. Therefore, industries will have benefits through various means which will make the products of better quality and add to the profits of the company.

• Ceramic filter as a common ingredient of foundries

Made of silicon carbide, the ceramic filter is a common ingredient of many foundries, where cast iron preparation is done. When the molten iron is passed through the chambers into the moulds, it is necessary to filter the material. In this place, the ceramic foam filter is used so that the molten metal is able to pass through without the impurities. During this cycle, there is improved removal of the impurities, which stick to the ceramic filter and the rest of the materials pass onto the moulding chamber. When made of Silicon carbide, the filter is able to provide many advantages.

• Advantages reflected for industries at several levels

There are advantages of using the foam filtration method in various aspects, such as in case of scrap control, increased productivity of the metals, improvements in the quality of the cast being prepared and in other operations after the cast is designed. So, there is a benefit on an overall basis, which turns out to be of advantage financially, quality of products and in improved productivity of the finished moulded goods. It is possible to use the SiC ceramic foam filter in plenty of industries, wherever there is need of filtering the molten metal when it passed into the mould chambers.

• Controlling the velocity of the moulded metals

When the velocity of the metal passage is reduced by the ceramic foam filter, there is improved gating system. The fall is checked and made smooth and uniform so that the metal moulding is done in a uniform manner. Cleaner metal will therefore lead to better metal consistency. Casting finish is better when silicon carbide filter is used. Many industries are using more numbers of such ceramic filters to ensure that there is improved output of the metal on the other side of the filters.

• Lowering the level of scrap in metal casts

For the industries, use of SiC ceramic foam filter means that there is less scrap in the metal. So, the scrap ratio is indirectly decreased by the use of such filtration process. Furthermore, companies have the liberty of using foams of different porosities, using these in different levels and across variety of angles. Suitable to the given metal foundry, the casting mould should be fitted with suitable ceramic foam filter as there are plenty of advantages of such processes, which is evident in the better yield of such castings.
