Description
Technical field
The invention belongs to cast casting preparation field, in particular to a kind of dedicated nodulizers of wind power plant casting.
Background technique
With the development of new energy, wind-power electricity generation enters the visual field of industry masses, wind power plant therein already
The requirement of casting is even more very high, and the preparation of the casting is typically required the spheroidal graphite cast-iron of high gauge, because of wind-power electricity generation casting
Itself need extremely high Anti-pull-press, elongation and extremely high rigidity.In addition, wind-power electricity generation casting is due in production application
Series of factors, therefore the requirement for nodulizer used in wind-power electricity generation casting is also relatively high, generally requires such
Nodulizer must satisfy certain anti-decaying spheroidisation ability, and Oxygen potential is high, and above-mentioned is all the nodulizer that wind power plant uses
The general main idea to be met
But even if China has the technique of many wind power plant casting, the nodulizer used also has to a certain extent
Standby certain anti-decaying spheroidisation ability, Oxygen potential, but with the development of casting manufacturing process, siliceous phosphorous sulfur-bearing in nodulizer
While amount is adjusted to minimumization, the dedicated nodulizer of wind power plant casting still keeps the decline ability of anti-nodularization, low
The certain those skilled in the art's strategic point of high impact technical problem to be solved under temperature.
Summary of the invention
Aiming at the problems existing in the prior art, the invention discloses a kind of dedicated nodulizer of wind power plant casting,
By the application of norium, the phosphorous sulfur content in nodulizer is enabled to be adjusted to for the content of heavy rare earth element
High impact that is minimum, being also equipped under low temperature, solves the problems, such as of the existing technology.
The present invention is implemented as follows:
A kind of dedicated nodulizer of wind power plant casting, which is characterized in that the nodulizer according to mass parts meter, specifically at
Divide as follows:
42-50 parts of silicon；5.2-6.8 parts of magnesium；0.4-1.2 parts of aluminium；0.8-3 parts of calcium；15-30 parts of iron；Norium 0.3-2.0
Part；
The norium includes yttrium, cerium, lanthanum, neodymium；The yttrium, cerium, lanthanum, neodymium mass parts accounting be yttrium: cerium:
Lanthanum: neodymium=1:1:1:0.1.
Further, the inovulant of baric is also mixed in the nodulizer.
Further, the mass parts accounting of the inovulant is 0.2 ~ 0.3% of iron in nodulizer, the inovulant
Granularity be 0.5 ± 0.1mm.
Further, sulfur-bearing, phosphorus content when the nodulizer handles magnesium iron are respectively less than 0.01%, lower sulfur-bearing, phosphorous
Amount can guarantee the high impact of casting at low temperature.
Further, the nodulizer further includes 0.07-0.2 parts of manganese according to mass parts meter.
Further, the silicon components are nanometer silicon carbide and micrometer silicon carbide silicon；The nanometer silicon carbide and micron
The mass parts ratio of silicon carbide is 2:1, and nanometer silicon carbide and micrometer silicon carbide silicon are due to large specific surface area, with spheroidal graphite cast-iron
Lattice Matching rate is high, can significantly improve the mechanical performance of wind power plant casting.
The beneficial effect of the present invention and the prior art with:
1) norium in the present invention includes yttrium, cerium, lanthanum, neodymium, and the use of the rare earth element of yttrium base therein can drop
The amount of magnesium needed for low ball agent can avoid decaying spheroidisation to the full extent；
2) due to can more or less there is the phenomenon that reversion during the preparation of wind power plant casting, element sulphur can be led
The decline ability of nodularization is caused, but the mass parts accounting of yttrium in the present invention, cerium, lanthanum, neodymium is yttrium: cerium: lanthanum: neodymium 1:1:1:0.1
Be used in mixed way, it is ensured that the phenomenon that the reversion of minimum flow, to ensure that nodulizer of the invention still keeps anti-nodularization
Decline ability；
3) element of the yttrium in the present invention, cerium, lanthanum, neodymium rare earth element with the use of silicon, magnesium, aluminium, calcium, iron etc., the wind-force of preparation
The phosphorous sulfur content of generating equipment casting is lower, and yttrium, cerium, lanthanum, the cooperation of neodymium rare earth element are higher with the affinity of sulphur, therefore phosphorous contain
Sulfur content since silicone content is lower, and can guarantee in low temperature to 0.01% hereinafter, therefore can guarantee the decline ability of anti-nodularization
Under high impact.
