1.The brand and chemical composition of yttrium-based rare earth spheroidizing agent for FD series wind turbine are shown in Label 1:

I. Characteristics of the product and Application Range

1. This product has an outstanding capacity of anti-nodularization degeneration, anti-distortion of graphite, anti-interferential elements. Used together with mating inoculant of the company, it can ensure that the area of the section is larger than 180mm, the nodularization of the bulk department is within 3 degree, the number of graphite balls is more than 200 /mm²，nodularization rate is higher than 85％.Besides, it can increase both the resistance to low temperature impact on toughness and the tensile strength values.

2. By adopting special techniques and high-purity raw material, it is very little interferential microelements and the purity is high.

3. The range of residual rare earth is wider than that of common rare earth spheroidizer. It has the advantage of small white mouth and simplifies the forced cooling process such as adding chillers.

3.The brand and chemical composition of the yttrium-based composite rare earth spheroidizing agent for ZY series medium-sized castings are shown in Label 3:

I. Characteristics of the product and application
1.This product has a relatively strange capacity of anti-nodularization degeneration, anti-graphite distortion and anti-interferential elements and strong capacity of ball reaction.

2.There is no need to worry about nodularization degeneration. We can easily produce real high-quality under existing working conditions. It can be widely used in heavy section (section > 80mm) casting production. Its processing technology is basically the same as that of light rare-earth nodulizer. It’s suitable for iron liquid of the temperature of 1400℃ -1550℃, ordinary pour-over process, with adding amount 1.0-1.8% (depend on the level of impurity content of the iron liquid ), after packaging the nodulizer, cover it with ferrosilicon or iron fillings, iron plate above, there is no need to take special desulphurization and cooling measures. After the ball reaction, in general cases, we can guarantee nodularization grade above grade 3 within 2.5 hours.

3.The nodularization rate is high, the graphite ball number is large, and the roundness degree is fine.
