One of the more important steps in the production of ductile iron is the inoculation of chemically active elements into the liquid metal. This can be done with a variety of inoculants. A steelmaking inoculant manufacturer can provide you with many options to choose from. However, not all inoculants are created equal. These inoculants are formulated to meet the specific needs of your product. You may find that a particular inoculant is better suited to your ductile iron manufacturing process than others.
The main reason for using an inoculant is to prevent the shrinkage of the cast iron. It is also a way to improve the spheroidization grade of the liquid metal. By doing so, you can save money and time by upgrading to a higher grade of steel. An inoculant is a mixture of ferroalloys and other chemically active elements which are introduced into the liquid iron during its solidification. As a result, it can improve the fluidity of the molten iron, as well as the form of molten iron impurities.
Silicon Barium is an artificial composite ferroalloy that is used as an inoculant. It is a highly efficient deoxidizing agent that can reduce the occurrence of smoke and flame. Furthermore, it can be utilized as an alloying agent, degassing agent, and reduction agent. In addition, it can also be used as an additive to cast iron.
The most basic method for inoculating a cast iron is to add a small amount of inoculant to the molten metal. Another option is to use the ladle method. A large variety of inoculant is available in paper bags ranging in capacity from 5 to 25 kg. Additionally, you can order in bulk, with a minimum of 20 days for delivery. If you have questions about your order, you can contact the supplier for further information.
Elkem Silicon Products is a manufacturer of inoculants, and has been known for their impressively-sized Bisnoc and Ultraseed inoculants. They have also recently developed a new inoculant, which is meant to enhance the graphite structure of ductile iron castings.
Another is the cored wire alloy. It is an alloy that is used for the foundry and steelmaking industries. This type of alloy can be used to purify liquid steel, to change the shapes of the impurities in the iron, and to increase the alloy yield rate. Also, the use of this alloy can help to significantly reduce the amount of alloy consumed and recast. Moreover, this inoculant can significantly reduce the chilling tendency of ductile-iron castings.
Finally, there is the Bismuth inoculant, which is designed for the ductile-iron nodularizing treatment. Specifically, it is a low-temperature alloy that is used to remove hard iron carbides, as well as to provide a more stable ductile-iron microstructure. Besides, it is said to produce a good ferrite/pearlite ratio.
