Alloy Description

Zircon Based Inoculant (FeSiZr) is a ferrosilicon-based ino-culant containing controlled amounts of the de-oxidizing elements Al, Ca and Zr. The combi-nation of these elements provides a strongernucleating effect than found with simpler inocu-lants. Zircon Based Inoculant (FeSiZr) may be used in bothgrey and ductile irons to enhance the control ofgraphite morphology and reduce chill levels.

Effect in Iron

Zircon Based Inoculant (FeSiZr) is an intermediate perfor-mance inoculant capable of reducing chill inareas of the casting which cool more rapidly. The application of Zircon Based Inoculant (FeSiZr) will refi-ne the graphite shape in thin or heavier sec-tions. Refined and uniform grey iron micro-structures are desirable for optimum enginee-ring properties, and avoidance of randomcoarse graphite flakes will provide an increasein tensile strength. Electric melted irons lowerin sulphur will respond more to the inoculationby Zircon Based Inoculant (FeSiZr).
Zircon Based Inoculant (FeSiZr) is suitable for additionalmodest control of soluble nitrogen in iron andfor ladle pouring conditions where oxidationcannot be avoided. Zircon Based Inoculant (FeSiZr) can beused in ductile irons to promote higher nodulecounts and reduce chill, but high additionsgreater than 0.6% are not recommended dueto the interference of Zr with the nodulizing ef-fect of Mg.

Application 
Zircon Based Inoculant (FeSiZr) Inoculant can be sized to suit allinoculation addition techniques. Ladle additionsshould be made as the ladle is between ¼ and¾ full of iron. It is good practice to weigh boththe iron and the inoculant to ensure consistentperformance from treatment to treatment.Smaller sized Zircon Based Inoculant (FeSiZr) may be ad-ded to the downsprue in the mould or preferab-ly to the stream of iron as it enters the pouringbasin. Late additions are advisable to avoid theeffect of nucleation fade when inoculated ironis held for periods longer than eight minutesbefore casting.

Nodulizer is the primary mean of accessing to ductile iron. This article will briefly analyze the classification and nature of the nodulizer.

The classification of the nodulizer

Divided by production of ductile iron castings, nodulizer can be classified as alloy-like nodulizer, massive nodulizer, core line nodulizer, power nodulizer.

1. Alloy-like nodulizer

But the ratio of rare earth divided by Mg in China foundries ranges from 0.5 to 2.2, in foreign this ratio ranges from 0.1 to 0.3.

1.1.1 Calcium alloy

The calcium and magnesium nodulizer is mainly used by Japan casting producers.

The production of Shin-Etsu (SHIN-ETSU), NC5, NCl0, NCl5, NC20, NC25, the content of magnesium changes from 4 to 28%. But there are small changes in calcium content; the range is from 20 to 31%. Chilling tendency of such alloys is small, but it requires a high processing temperature and large amount of residue after treatment.

1.1.2 Nickel magnesium alloy

Nickel magnesium alloys is produced by International Nickel Company. The content of nickel is up to 82 ~ 85% while Ca is 20 % and Mg is 13%-16 %. But nickel is 57 to 61% minimum (which Mg 4 .0 ~ 4.5 %, Ca <2.5 %, Fe 32 ~ 36 %). German chemical company produces nickel-metal magnesium alloy in which Ni 47 ~ 51 %, Mg l5 ~ 17 %, C1.0 % Si28 ~ 32 %, RE1.0 %. The advantage of these alloys is heavy, reaction steady and nickel alloy can play a role in alloying. But it is characterized by expensive, this alloy in China, basically is not applied in China foundries.

1.1 Nickel-silicon alloy

Nickel-silicon alloy is currently not applied in China basically.

1.2 Pure magnesium alloy

Pure magnesium alloy processing need a dedicated pressure make magnesium package, and the magnesium absorption rate is high. But it needs very strict security dealing measures leading to a smaller proportion of the production application.

1.3 Rare earth

Rare earth is used when iron foundry invented ductile iron, which promotes the process of ductile iron industrial applications greatly.

But the price is high, and it has a large chilling tendency. If the mount is over, it will make graphite metamorphosis .So now it is no used alone as nodulizer, only as an auxiliary elements.

2. Massive nodulizer

Press magnesium and iron and silicon content designed directly into compression molding. Silicon in this nodulizer is very low. So it is referred to as a low pressure block nodulizer, which provides subsequent room and conducive to production of cast iron. But this alloy is easy to float, the effect of treatment is volatile. So it is better to use with massive nodulizer

3. Core line nodulizer

Coat the magnesium powder, iron powder in a thin steel plate or steel plate and cast it into the molten iron to achieve the purpose of balling. But this nodulizer is expensive, the investment in equipment is large and the absorption rate of alloy is high, so the cost of processing ductile iron is almost no increase.

4. Power nodulizer

Power nodulizer is a Russian patent. Mix with the magnesium powder and inhibitors into the bag. Make the molten iron flow through the surface of alloy, reacting with alloy layer and layer. Iron foundries call this special process MC.

Each nodulizer has its own advantages and disadvantages, iron foundries should base on their products and production process to choose appropriate nodulizer, in order to decrease the cost of investment and increase the production efficiency.

• Sr Based Inoculant is still the most widely used inoculant in the treatmentFor many years, Sr based inoculant has been the world famous inoculant, probably still the most widely used in the production of grey iron globally. Today we have a portfolio of inoculants designed to cover a wide range of applications in all cast iron segments.
• of grey irons.
• The powerful chill removal properties means lower application rates and this leads to a reduction in shrinkage tendency.
• Sr Based Inoculant inoculant is available in a 50% silicon version to give more penetration into the metal stream and may be used at low pouring temperatures.
