Abstract

The invention relates to iron-based alloys with a low coefficient of expansion, containing at least 34% of nickel, in particular for the manufacture of shadow masks for colour television sets. The invention is characterized in that an iron/nickel ratio from 1.75 to 1.83 with the coefficients of thermal expansion of less than 1 x 10<-6>/K is set for use in the temperature range from 20 to 100 Celsius system, and an iron/nickel ratio from 1.68 to 1.72 with coefficients of thermal expansion of less than 2 x 10<-6>/K is set for use in the temperature range from 20 to 200 Celsius system.

Description

Iron-nickel alloy
The present invention relates to contain at least 34% (quality) Ni, be specially adapted to produce the low thermal expansion iron-nickel alloy of colour television set shadow mask.
The ferrous alloy that this class contains the 36%Ni that has an appointment has the low coefficient of expansion certainly in the temperature range of room temperature to 100 ℃.Therefore, there are tens of kinds of these class alloys to be used for some certain applications, under said application scenario, also still require this alloy part to have constant length even temperature changes, for example the application in precision instrument, clock and watch, bimetal.Even along with color TV towards more high resolving power, color fidelity and under disadvantageous light condition, also there is the direction of better contrast to develop, more specifically say so for the TV tech (HDTV) that reaches high definition, the iron nickel material is used for the porous shadow mask just increasingly extensively.In 20-100 ℃ the temperature range that the existing-quality television picture tube often is in, (950 ℃, 30min) thermal expansivity that is had is about 1.2 * 10 under as-annealed condition to contain the industrial iron nickelalloy of the 36%Ni that has an appointment -6/ K or even higher; In 20-200 ℃ temperature range, their thermal expansivity is about 2.2 * -6/ K or higher.Because the increase of mesh structural porous shadow mask heat load is up to 200 ℃ temperature range, will become much even more important from now on.Therefore the objective of the invention is to provide a kind of iron-nickel alloy of low thermal expansion, they are no matter be in the residing 20-100 of common TV picture tube ℃ temperature range, still in the residing 20-200 of mesh structural porous shadow mask ℃ temperature range of kinescope in the future, all has alap thermal expansivity, and heat, cold-forming property that satisfaction is very arranged particularly have satisfied processing characteristics when producing the shadow mask of colour television set at these alloys of processing.
Now find unexpectedly, when the temperature range that is used for 20-100 ℃, selecting iron-nickel ratio for use is the iron-nickel alloy of 1.75-1.83, and when the temperature range that is used for 20-200 ℃, then select for use to have iron-the nickel ratio is the iron-nickel alloy of 1.68-1.72, this problem can be resolved the most satisfactorily, and these alloys are except containing at the most 0.009% carbon and at the most 0.1% the manganese, also containing common impurity only very a spot of, that bring into when smelting.The present invention has obtained its excellent effect owing to described iron nickel ratio.This effect aspect the coefficient of expansion is improved by the impurity of controlledly regulating above-mentioned other alloying constituents and bring into when smelting.In addition, alloy of the present invention also has outstanding processing characteristics, and does not require additional processing step in the process of making shadow mask.The thermal characteristics of this alloy also has the permanent stability that meet various requirement.
Preferable embodiment of the present invention has the feature of dependent claims.Like this, aluminium and silicon total amount are that the iron-nickel alloy of 0.075-0.45% is preferable.Because such alloy has been arranged, required low thermal coefficient of expansion just can be regulated in the said temperature scope reliably.When the maximum level of manganese was 0.07%, except the maximum level of Si is 0.05%, the content of aluminium should be in the scope of 0.1-0.4%.If the content of aluminium between 0.15-0.40, is preferably between the 0.2-0.4%, then might reach further optimizing.
The maximum manganese content of this iron-nickel alloy can be 0.1%, and, except the Al that contains 0.001-0.01%, also can contain 0.05-0.30%'s SiPreferably silicone content is adjusted to 0.10-0.30%, is preferably 0.15-0.30%.Though most suggestion thinks that for regulating low thermal expansivity, silicon is considered to a kind of extremely harmful element, yet uses the silicon more excessive than aluminium to test, show unexpectedly, within the scope of the present invention, if 0.001-0.01% is being arranged AlAdd 0.05-0.30%'s again under the condition that exists Si, just can be in 20-100 ℃ temperature range even be adjusted to more satisfactorily and be lower than 1 * 10 -6The very low coefficient of expansion of/K.Al and Si add as reductor, its objective is the purity that improves steel.
Tabulate down 1 iron-nickel ratio between 1.75 and 1.83 and temperature range under the common conditions between 20-100 ℃ with embodiment E 1, E 2, E 3Iron-nickel alloy ST with prior art 1And ST 2Compare, wherein, E 1Has the silicon and the aluminium of equivalent basically, E 2Has excessive aluminium, E 3Has excessive silicon.Table 1 has also comprised the Embodiment B of alloy of the present invention 1-B 8
