Abstract
The invention discloses a wear-resistant stainless steel small glass bottle mould which comprises the following components by mass percent: 0.05%-0.50% of C, 15.5%-19.0% of Cr, 1.7%-1.9% of Ni, 0.45%-0.58% of Mn, 0.42%-0.55% of Si, 0.015%-0.055% of P, 0.010%-0.050% of S and the balance of Fe and general impurities, wherein C has the effects of influencing the metallographic structure of the mould and improving the heat conductivity of the mould; Cr has the effects of improving the hardness and the wear-resistant performance of the mould. According to the stainless steel small glass bottle mould prepared by mixing the components, the anti-wear and anti-oxidation performances in a high-temperature state are remarkably improved, the service life is 1,800,000 times (the service life exceeds that of a general cast glass mould by 80%), and the hardness of the glass mould is 288-298HBW.
Description
Technical field
The present invention relates to a kind of abrasion-resistance glass mould (glass mold material), specifically a kind of small-size glass bottle mould (glass mold material) of abrasion-proof stainless steel material.
Background technology
Glass mold is as glass bottle mould, and normally used material is the special cast alloy iron of glass mold and copper alloy, and what it was mainly produced is substantially all glasswork bottle and the Light weight Container that build is larger.The larger glass mold of build is when with frequent contact of high temperature glass frits, and glass mold constantly heats up, but because its build is larger, its radiating rate is also very fast.
Generally, the abrasion resistance of cast iron materials is poor, the glass mold of especially small bottle for cosmetics, and because the mould heat absorption of small volume is fast, but because its area of dissipation is less, therefore heat radiation is slower, and therefore heat resistanceheat resistant wearing and tearing, resistance of oxidation are poor.
For the less glass mold of build, we attempt taking high-abrasive material to solve the thermal fatigue lost material drawback of frequent appearance.Utilize abrasion-proof stainless steel material to be used as little glass mold material, can effectively avoid resistance to wearing under material at high temperature state, the poor problem of antioxidant property.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of phial mould taking stainless steel as mother metal, can under the condition of high temperature, resistance to wear, anti-oxidant, the cast iron die that solves smaller size smaller absorbs heat soon, heat radiation is slow, heat resistanceheat resistant wearing and tearing, the poor problem of resistance of oxidation.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A small-size glass bottle mould for abrasion-proof stainless steel material, its component and mass percent are:
C:0.35％--0.50％
Cr:18.0％-19.0％
Ni:1.7％--1.9％
Mn:0.45％--0.58％
Si:0.42％--0.55％
P:0.015％—0.055％
S:0.010％--0.050％
All the other are Fe and common impurity.
The effect of C is the metallographic structure that affects mould, increases the thermal conductivity of mould, and the effect of Cr is the hardness that increases mould, promotes wear resistance.
But carbon content is lower than 0.9% time, and along with the increase of carbon content, the intensity of mould and hardness will rise, but plasticity and toughness will decline.Glass mold needs enough intensity and intensity and hardness, but larger hardness is unfavorable for post-production, and therefore, the present invention adds the carbon of 0.35%--0.50%, to obtaining suitable hardness and good plasticity and toughness.But the carbon content of 0.35%--0.50% is still less comparatively speaking, therefore the present invention adds the Cr of 18.0%-19.0%, and Cr increases the hardness of mould on the one hand, and Cr, as carbide forming element, promotes wear resistance on the other hand.
As preferably, C mass percent is that 0.50%, Cr mass percent is 19.0%.
The present invention is by the little glass mold of stainless steel of above element proportioning, under the condition of high temperature, resistance to wear, antioxidant property obviously improves, reach work-ing life 1,800,000 times (exceeding 80% work-ing life than common casting material glass mold), the glass mold hardness that above-mentioned materials obtains is 288-298HBW.
