Abstract
The invention discloses a rare earth inoculant-promoted D-type graphite alloy glass mold. Rare earth is added into molten iron to refine a cast structure, improve the shapes and the distribution of nonmetallic inclusions and help to improve the properties of a material. Therefore, the addition of the rare earth improves the mechanical properties of cast iron, and the cast iron has better shock resistance, wear resistance and cutting processing performance than steel and has tensile strength which is 20-50 MPa higher than that of an ordinary cast.
Description
Technical field
The present invention relates to a kind of glass article, particularly a kind of alloy glass article that is added with the rare earth nucleating agent.
Background technology
The glass article industry is through high speed development recent years, and the quality of materials of domestic glass article has had significant progress, and dissimilar materials are used widely, to adapt to the requirement of different manufacturers, different type of machines, different glass characteristic.Along with further developing of system bottle technology; System bottle speed has improved more than 25% than in the past; Mould continually with 1100 ℃ of hot glass contact, stand high temperature oxidation, and wear and tear in the extruding bed die and the hot glass slides contact friction of drift; So high temperature oxidation is two important factors that influence mold performance with wearing and tearing, and is wherein important with oxidation.
Research shows that D type graphite ferrite matrix cast alloy iron can improve the performance of mould, has satisfied high-speed bottle machine to the material requirements of cast iron class.
Summary of the invention
The purpose of this invention is to provide a kind of high-performance, can satisfy the alloy glass article of high-speed bottle machine system bottle requirement.
In order to realize above-mentioned purpose, technical scheme of the present invention is: a kind of rare earth nucleating agent promotes the alloy glass article of D type graphite, and it comprises the component of following per-cent:
All the other are Fe and a spot of impurity.
The hardness of said mould is 130-170HBS.
The tensile strength of said mould is 150Mpa.
Rare earth of the present invention is added in the molten iron; Refined cast structure; Improve the shape and the distribution of non-metallic inclusion, help the raising of material capability, thereby the adding of rare earth has improved the mechanical property of cast iron; Its shock resistance, wear resistance and machinability are not worse than steel, have improved 20-50MPa than general foundry goods tensile strength.
Trace rare-earth can promote the growth of primary crystal austenite skeleton in the D type Graphite Iron Cast, to strengthening matrix certain effect is arranged.
Trace rare-earth ability refinement D type graphite; Its length only for do not add that rare earth breeds 1/3～1/4, graphite quantity increases, the passivation of growth of graphite front end, branch, petal-shaped form also make moderate progress; Alleviated the destruction of graphite to matrix greatly, this is the major cause of rare earth reinforced D type Graphite Iron Cast.
Often contain detrimental impurity such as aerobic, sulphur in the molten iron, these impurity can make foundry goods produce pore, crack, and form slag inclusion, and intensity, toughness and the plasticity of material are reduced.And the binding ability of REE and sulphur, oxygen is strong, generates infusible compound, in molten iron, can play the desulfurization phlogistication.Simultaneously rare earth can also be eliminated the detrimentally affect of harmful element in the molten iron such as Pb, Zn, Bi etc.
Dies cavity 0-20mm:D type graphite of the present invention allows to contain＜5% A type graphite grade: 6-8 level; 20mm is later on A or D type; Austenite content: >=95%, do not allow carbide.
Embodiment
Get alloy material and carry out melting, pour (0.2-0.4%) in the bag into through composition detection, rare earth nucleating agent then, molten iron is poured in the bag, pour into a mould, again foundry goods is carried out stress relief annealing, carry out inspection after construction at last.
The per-cent that guarantees mold halves is:
All the other are Fe and a spot of impurity.
In the D type Graphite Iron Cast process of setting of eutectic or nearly eutectic composition, at first separate out the primary crystal austenite.Along with the iron liquid temp descends, the primary crystal austenite is branch and growing up constantly, and primary crystal austenite skeleton branch is many more, and the intensity of cast iron is relatively just high.Rare earth can enlarge primary crystal austenite growth temperature zone.So it is more sturdy than what breed without rare earth.When dendrite increases, the space of leaving growth of graphite for is just more little, and graphite crystal nucleus is intensive relatively, receives the obstruction of skeleton during growth of graphite, final form than A type graphite little the D type graphite of Duoing.
Rare earth can not only impel the austenitic growth of primary crystal, is again to hinder one of graphited element, when eutectic transformation, works the graphited effect that hinders, and reduces the speed of growth of graphite.Sulphur in rare earth and the iron liquid, oxygen generate sulfide and oxide compound simultaneously; Can be as the external nucleus of graphite crystallization, make between primary crystal austenite skeleton that graphite crystal nucleus increases in the iron liquid, more intensive; Therefore the D type graphite after breeding increases than uninoculated D type graphite quantity, and size reduces greatly.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
