Abstract
This case discloses a kind of carbon silico-calcium inovulant, includes the material of following parts by weight：The silicon of 38~40 parts by weight, the calcium of 10~12 parts by weight, the carbon of 26~28 parts by weight, the sulphur of 0.1~0.3 parts by weight, the iron of 2~4 parts by weight, the boron of 0.01~0.03 parts by weight, the beryllium of 0.02~0.04 parts by weight, the niobium of 0.5~1.5 parts by weight and the molybdenum of 0.05~0.1 parts by weight, the rubidium of 0.05~0.1 parts by weight, the rhenium of 0.05~0.1 parts by weight and the nickel oxide of 0.005~0.01 parts by weight.This case passes through to being improved and optimizated without rare earth composite carbon silico-calcium formula of modifying agent, introduce a variety of elements with synergistic effect, effectively increase the Oxygen potential and number of graphite ball of inovulant, chilling tendency of the inovulant to spheroidal graphite cast-iron is reduced simultaneously, and greatly reduces production cost and the destruction to environment.
Description
Technical field
The present invention relates to a kind of inovulant, more particularly to a kind of carbon silico-calcium inovulant for being used to produce nodular cast iron pipe fittings.
Background technology
In cast iron, a number of carbon can be contained, this carbon can combine closely with iron, and carbon is in the cast iron of solidification
Form is very important for the performance of ironcasting.If this carbon is referred to as white iron in carbonization Iron activiation, the cast iron,
It is hard and crisp, and practicality is very poor.If carbon is in graphite state, the cast iron is soft, easy to process, and it is referred to as gray cast iron, practical.
Graphite state can be divided into sheet, compact shape and spherical again, and wherein spherical-like morphology can show highest intensity and most
The cast iron of extending form.In Solidification of Cast Iron, the glomerate additive of graphite shape is set to be referred to as inovulant.Generally, with ball
Oxygen potential, number of graphite ball and the chill depth of black cast iron weighs the quality of inovulant.
Although in the inovulant of some existing comparative maturities of prior art, these inovulants are mostly rare-earth type inovulant,
It is understood that the exploitation of rare earth causes the damage of unrepairable to environment, therefore, how not only to be broken away from inovulant field
Dependence to rare earth, and more high-quality more efficient inovulant can also be produced, become problem instantly urgently to be resolved hurrily.
The content of the invention
For above-mentioned technological deficiency, it is an object of the invention to provide one kind to have lower chilling tendency, higher Oxygen potential
And higher number of graphite ball without rare earth composite carbon silico-calcium inovulant.
Technical scheme is summarized as follows：
A kind of carbon silico-calcium inovulant, include the material of following parts by weight：
Preferably, described carbon silico-calcium inovulant, in addition to the niobium of 0.5~1.5 parts by weight and 0.05~0.1 parts by weight
Molybdenum.
Preferably, described carbon silico-calcium inovulant, the rubidium of 0.05~0.1 parts by weight is included.
Preferably, described carbon silico-calcium inovulant, the rhenium of 0.05~0.1 parts by weight is included.
Preferably, described carbon silico-calcium inovulant, the nickel oxide of 0.005~0.01 parts by weight is included.
The beneficial effects of the invention are as follows：By to being improved and optimizated without rare earth composite carbon silico-calcium formula of modifying agent, introducing
A variety of elements with synergistic effect, effectively increase the Oxygen potential and number of graphite ball of inovulant, while reduce inovulant
To the chilling tendency of spheroidal graphite cast-iron, and greatly reduce production cost and the destruction to environment.
Embodiment
With reference to embodiment, the present invention is described in further detail, to make those skilled in the art with reference to specification
Word can be implemented according to this.
This case proposes the carbon silico-calcium inovulant of an embodiment, includes the material of following parts by weight：
As another embodiment of this case, wherein, in addition to the niobium of 0.5~1.5 parts by weight and 0.05~0.1 parts by weight
Molybdenum.
As the another embodiment of this case, wherein, include the rubidiums of 0.05~0.1 parts by weight.
As the another embodiment of this case, wherein, include the rheniums of 0.05~0.1 parts by weight.
As the another embodiment of this case, wherein, include the nickel oxide of 0.005~0.01 parts by weight.
Following table lists the concrete composition and its performance parameter of different embodiments：
*Note：Chill depth=(white iron length/ironcasting overall length) * 100%
Following table lists the concrete composition and its performance parameter of different comparative examples：
*Note：Chill depth=(white iron length/ironcasting overall length) * 100%
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, it is of the invention and unlimited
In specific details.
