Description
Technical field
The present invention relates to a kind of glass mold material, specifically a kind of cast-iron alloy glass mold material.The present invention also relates to
And the method using above-mentioned cast-iron alloy glass mold material manufacture glass mold.
Background technology
During glassware forming, melten glass of the mould continually with more than 1100 DEG C contacts, and is subjected to aoxidizing, gives birth to
The effect such as long and heat fatigue, meanwhile, each contact surface of mould is worn due to the friction with glass.This requires glass molds
Tool has that anti-oxidant, antibiosis is long, thermal fatigue resistance and the performance such as wear-resisting.In addition, glass mold is in actual production, it is desirable in high temperature
Under can carry out quick heat exchange, and the temperature field at each position of mould makes every effort to keep uniform, and this requires glass mold
Material has good heat conductivility, and this directly affects the quality and production efficiency of glassware.Good thermal conductivity can make
The thermograde of mould minimizes, so as to extend the life-span of glass mold.
Material of the cast iron as manufacture glass mold, occupies leading position at present, it is contemplated that in considerably long from now in the period of
Also will not change, and the gray cast iron material of D type graphite is the main material of glass mold.Its reason is that D type graphite is interdendritic
Point graphite, because its graphite by dendrite in point-like and being isolated, thus, its there is good inoxidizability and by glass mold
Widely apply.It is aided with certain alloying again, the anti-wear performance of material, high-temperature behavior is usually improved using the member such as V, Ti, Mo
And antioxygenic property.Thus, this kind of alloy cast iron has become the main flow of glass mold, and its life-span has also stably reached 800,000
More than secondary, market and client's accreditation have been obtained.
But the gray cast iron of D type graphite there is also it is notable the drawbacks of, be exactly its heat conductivility extreme difference, be unfavorable for glass mold and exist
Preferably heat exchange is obtained in production process, has had a strong impact on the quality of production and efficiency of glassware enterprise.
The content of the invention
It is an object of the invention to provide a kind of cast-iron alloy glass mold material, the material is not sacrifice glass mold original
The situation of performance, its material thermal conductivity is greatly improved, so as to lift the quality of glassware and production efficiency, and lifting glass
The mold use life-span.
In order to reach above-mentioned technical purpose, the technical scheme is that：
A kind of cast-iron alloy glass mold material, it includes following weight percent composition：C 3.0~3.6%, Si 1.4
~1.6%, Mn 1.2~1.8%, P≤0.02%, S≤0.02%, Ni 1.5~2.5%, Mo 0.3~0.8%, V 0.7~
0.9%th, Ti 0.22~0.26%, surplus are Fe and inevitable impurity.
Preferably, the weight percentages of components is：C 3.2%, Si 1.6%, Mn 1.6%, P≤0.02%, S≤
0.02%th, Ni 1.5%, Mo 0.75%, V 0.9%, Ti 0.26%, surplus are Fe and inevitable impurity.
The blank of glass mold is casting, it is ensured that inner chamber obtains good D types graphite it is necessary to ensure that iron liquid has
Have a larger degree of supercooling and larger cooling velocity, and to ensure to form A type graphite beyond 5mm, this require iron liquid have compared with
Small degree of supercooling and cooling velocity, to solve this on same blank to contradiction, be the difficult point of the project, and the wound of project
New part.
Mo, Ni should not add higher amount, not just merely because Ni, Mo are precious metal.It is primarily due to：Although Mo,
Ni can improve the plasticity, inoxidizability and volume stability of alloy, and have the ability for refining graphite.But drawback is also obvious
, i.e., it is pearlite stable element.Therefore, the above-mentioned addition of optimum choice of the present invention.Meanwhile while Mo, Ni addition,
Also need addition V cooperation.In the present invention, on the basis of V is as alloy heat resistance is improved, the graphite of alloying element is effectively facilitated
Change, while Mo, Ni beneficial effect in retaining alloy, hinder graphitization to promote the unfavorable shadow of matrix medium pearlite formation
Ring.
The present invention is by the proportion optimizing of component, the advantages of keeping original V, Ti, Mo cast iron, and working face is D type stones
Ink, the anti-oxidant of such glass mold are fully ensured.But remaining position of raw material is also essentially based on D type graphite, and this
Project-developing turns into substantially all for A type graphite (note beyond 5mm：B type eraphite all around A types, point midway D types, so also leading
If A type graphite), and the heat conductivility of A type graphite is much due to D type graphite.
