Elkem_TI_15 Selection of Inoculants for Grey Cast Iron_ …
This value can be calculated using a mathematical equation, and the following formula is commonly applied for cast iron: CE = %C + %Si + %P 3 Addition Methods Consideration should also be given to the method of adding the inoculant.
Inoculant is a potential promotor of "a" type perlitic graphite structure of carbon in cast iron. Chilling effect and blow holes can be avoided to a maximum degree with the help of imoculant. Special grey iron casting containing chromium, vanadium and boron can be produced easily by using inoculant.
New developments in high quality grey cast irons
inoculant) and three technological stages in electric melting of iron (superheat, pre-conditioning of base iron, final inoculation). Attention is drawn to a control factor (%Mn) x (%S) ensuring it equals to 0.03 – 0.06, accompanied by 0.005wt.%–0.010wt.% Al and/or

Carbon Inoculant It is widely used in casting and inoculation of grey cast iron automobile parts such as cylinder block and cylinder head The proportion of fixed carbon is between 50 60 and the rest are trace elements such as Ba Ca and Zr The absorption rate of
Additional procedural advantages of the mold inoculant SMW insert are due to the ability to precisely calculate the required dose. e.g. P 300, P 500 and/or P 800 – in order to ensure efficient and prompt inoculation. This will ensure that the cast iron that flows

Reactive elements in cast iron will be present both dissolved in the iron and coined with other elements to form particles such as oxides, sulphides, nitrides, etc. Such non-metallic particles will normally be lighter than the liquid iron, which means that there will be constant movement upwards of inclusions as the lighter particles float to the surface.

Why inoculation required in cast iron castings? Which is …
Cast iron is susceptible to a problem called chilling. Some edges and particularly thin, pointed or long parts of a cast part may cool off much faster and freeze without allowing graphite to precipitate out as flakes. Graphite precipitation provid
An investigation of the effect of five different inoculants on the metal expansion penetration in grey cast iron …
The choice of inoculant used in grey cast iron production today is probably one of the most important parameters in obtaining good quality castings. In an earlier investigation, ten different inoculants were tested and studied by quick cup casting as well as in a

You can use SMZ® as the single inoculant producing a variety of cast iron grades. It is perhaps the oldest trade name for an inoculant that is still in use today. Originally produced by Union Carbide, the ferroalloy is now made at Elkem plants in Norway and Canada (click here to go to our plants), along with production of other quality inoculants, such as Superseed® inoculant.
