Abstract
The invention aims to provide a color picture tube incorporating the shadow mask made from the invar alloy steel sheet. The production method is characterized by hot working a slab of an alloy consisting of 33 to 40 wt.% of Ni and the balance of Fe, so that a planar integration of the {100} plane of the rolled surface is 60 to 80 %.
Description
Technical field
The present invention relates to a kind of colour picture tube (hereinafter referred to as CRT) that the shadow mask of being made by invar alloy steel sheet material is housed.More specifically, this shadow mask is made by have superior corrosive Invar alloy when forming the some hole (small smooth hole) of shadow mask, the present invention relates to be equipped with the colour picture tube of this shadow mask.
Prior art
As the material of the shadow mask that uses for colour picture tube, adopt the steel sheet of making by Invar alloy or aluminium killed steel.The production process that is used for the thin plate of the shadow mask that Invar alloy makes is: the fusing Invar alloy, the Invar alloy of casting fusing forges and the above-mentioned alloy of hot rolling, carries out pickling subsequently and grinds de-scaling, after this carries out cold rolling again and annealing.The invar alloy steel sheet material that utilizes photoetching technique to obtain is thus got a hole, can produce plain bonnet like this.After plain bonnet is annealed, pressure forming is desired shape, melanism handles, just can be installed in the colour picture tube.
Shadow mask can serve as the anode of the electron beam of launching from electron beam gun, also can be used as iris, and this moment, its allowed to be launched on the point of the fluorescence coating that spreads on the panel by the electron beam in a hole.About a kind of effect in back, the some hole directly influences sharpness, irregular color or the irregular brightness of the image of colour picture tube demonstration, so they are very high to the requirement of dimensional precision.The point hole constitutes (through hole is hereinafter referred to as Br Th hole) by small-bore part (hereinafter referred to as aperture), wide aperture part (hereinafter referred to as macropore) and connection hole portions.Wherein aperture is positioned at the surface of cover thin plate like the thin dish, and faces cathode is promptly over against electron beam gun; Macropore is positioned at another surface of cover thin plate, and is relative with panel; The two meets aperture and macropore at place, Br Th hole.The function of Br Th hole energy remarkably influenced electron beam iris.
Usually, for the shadow mask of high definition, the thickness that is used for the invar alloy steel sheet material of shadow mask is 100～250 μ m, and the spacing between the center in 2 holes is about 250 μ m.Br Th bore dia respectively is about 120 μ m, and they should rounded and diameter homogeneous.In addition, in view of this function of iris, invar alloy steel sheet material is strict with corrosion surface and is had level and smooth and uniform surfaceness.Thus, be starved of and improve corrosive property, the promptly this corrodibility that is used for the invar alloy steel sheet material of shadow mask.
As improving the corrosive method of invar alloy steel sheet material, in such as Japanese patent application publication No. Hei-2-51973 and disclosed Japanese Patent No. Sho-61-190023, some technology have been proposed, these technology are used for reducing the Invar alloy unavoidable impurities, and these open strictnesses have limited the amount such as C, O and these unavoidable impurities of N.Really, for the high precision corrosion technology that is used to form shadow mask etc., these technology of proposition are very crucial, but only reducing unavoidable impurities can not solve the corrosive all problems of Invar alloy.In addition,, in such as disclosed Japanese Patent Hei-61-39343, Japanese patent gazette Hei-2-9655 and Hei-6-279946, some technology have been proposed, these technology strict control grain-size or crystalline orientation as the method for improving the Invar alloy metallographic structure.These technology have been well-known and also have been important for the corrodibility of improving Invar alloy.For polycrystalline material, crystal grain is thin more, and with regard to crystalline orientation, the chance that produces difference between the grain attack rate can be more little, thereby can make the erosion rate uniformity.In addition, Invar alloy has centroid cubic lattice structure, and it has with austenitic stainless steel is the identical structure of Stainless Steel Alloy in the steel field.As everyone knows, the material of centroid cubic lattice structure, along high atomic density such as { 111} face and { more even when the 100} face corrodes than other face.
Therefore, above-mentioned prior art simply being made up the corrodibility that is not sufficient to make as the Invar alloy of the material for shadow mask of high definition improves.In addition, the Invar alloy that industrial production is this to have fine grain tissue and a crystalline orientation needs complicated Controlling System, and this system runs through processes such as whole cold rolling, annealing, and they have constituted an expensive principal element.Today, strong just day by day for the demand of shadow mask cheaply.From now on, people will seek higher-grade shadow mask and material for shadow mask cheaply.
The problem that the present invention will solve
The object of the present invention is to provide the invar alloy steel sheet material of industrial economy, it can be used as has better corrosive material for shadow mask, the method for producing above-mentioned invar alloy steel sheet material, shadow mask that Invar alloy is made is provided and the colour picture tube of above-mentioned shadow mask is housed.
The method of dealing with problems
Colour picture tube is equipped with the shadow mask of being made by invar alloy steel sheet material, basic composition is of this invar alloy steel sheet material: 33～40%Ni (weight), all the other are Fe, and invar alloy steel sheet material has 60～80% { 100} texture ratio at its rolled surface.
Embodiment preferred
At first, the Ni content in the Invar alloy is restricted to 33～40% (weight).When the Ni content in the Invar alloy is in above-mentioned scope, the thermal expansivity of Invar alloy will significantly reduce.When the shadow mask of being made by this Invar alloy is installed on the colour picture tube like this, even temperature variation does not exist such as problem such as pattern distortion or color be irregular yet.On the contrary, when Ni content less than 33% (weight) or when being higher than 40% (weight), the thermal expansivity of Invar alloy increases, so produce such as problems such as above-mentioned pattern distortion or color are irregular.When invar alloy steel sheet material was used to produce the shadow mask that uses for colour picture tube, its technical problem was how to improve the corrodibility of Invar alloy.Yet when paying the utmost attention to the characteristic of improving the Invar alloy thin plate, it is harsh that the condition of industrial production shadow mask becomes, and production process becomes more complicated.Therefore Industrial processes can access Invar alloy its rolled surface have 60%～80% { in the scope of 100} texture, be necessary to improve its corrodibility.When { when 100} texture surpassed 80%, the corrodibility of Invar alloy improved quite for a short time.At this moment, will increase the cold-rolled compression ratio on the contrary, so just need this Invar alloy of repeat-rolling, thereby prolonged cold rolling cycle time, and delay to produce.In addition, roll is often destroyed owing to the work hardening of Invar alloy, makes production cost strengthen.In addition, the etching system of producing shadow mask has had remarkable improvement recently, and can under high pressure spray high temperature corrosion liquid.That is, mainly by the what is called of in the solubilizing reaction of Invar alloy, carrying out " mechanical erosion " by pressure injection.Therefore, provide the more superior corrosive environment of producing shadow mask.So, in view of the price that will produce shadow mask is reduced to a certain degree requirement, with Invar alloy { 100} texture ratio is restricted to and the highlyest is about 80% and is necessary.Otherwise, when Invar alloy { 100} texture ratio is less than 60% the time, and its corrodibility reduces, so is defined as 60% under it.
According to above-mentioned viewpoint, explain to have 60～80% { production method of the invar alloy steel sheet material of 100} texture ratio below.The Invar alloy of fusing basic composition is: 33～40%Ni (weight), all the other are Fe, and it is cast into steel ingot and forging, or adopt continuous casting to produce slab, are thermally processed into the hot rolling slab subsequently, eliminate segregation simultaneously.By pickling and shredder grinding steel slab surface is carried out de-scaling.After this, slab becomes steel sheet after first cold working, annealing and secondary cold working.This once cold rolling is usually by carrying out cold rolling with roll.For the cost of the rolling surface tissue of Invar alloy and cold-rolled process, compression ratio all is an important factor.From the result of different experiments of the present invention, first cold-rolled compression ratio is preferably 80% or less than this value, and more preferably 50～80%.When compression ratio less than 50% the time, can not obtain at rolled surface that enough { 100} texture ratio only is less than 60% described ratio, is lower than the described { lower limit of 100} texture ratio.。Otherwise, even when compression ratio was higher than 80%, { ratio of 100} texture did not obviously increase yet.At this moment, not only increased the load that acts in the operation of rolling in rain, and the destruction of significantly having strengthened breaker roll.Therefore the upper limit of compression ratio is defined as 80%.The annealing of carrying out in temperature more than 550 ℃ or 550 ℃ subsequently its objective is in order to recover the rolling surface tissue and to make its recrystallize.This annealing is to { improvement of 100} texture ratio has effect.When annealing temperature was lower than 550 ℃, recrystallize can not reach required degree and { ratio of 100} texture will significantly reduce.Otherwise, when annealing temperature is higher than 950 ℃, significantly quickened recrystallize, and the crystal grain change being big, this can make Invar alloy thin plate corrodibility reduce.Therefore, preferred annealing temperature is 650～950 ℃.Adopt the purpose of secondary cold-rolling to be to improve hardness and intensity by the work hardening of Invar alloy, like this by annealing obtain a high proportion of { 100} texture can keep getting off, and can give invar alloy steel sheet material required hardness.Therefore, the compression ratio of secondary cold-rolling is defined as 50% or be lower than 50%.When this compression ratio is higher than 50%, by annealing obtain a high proportion of 100} texture can reduce, thus forfeiture annealed effect.Therefore the compression ratio of secondary cold-rolling is preferably 50% or less than 50%, and more preferably 0.05～40%.When compression ratio less than 0.05% the time, the invar alloy steel sheet material behind annealing back and the secondary cold-rolling does not have difference aspect hardness, that is to say, secondary cold-rolling does not have remarkable influence to Invar alloy at this moment.The invar alloy steel sheet material of Sheng Chaning does not have enough hardness and intensity thus, makes the transmission workpiece have problems owing to steel plate distortion or suchlike reason in corrosion process like this.Usually, the hardness that Invar alloy requires is Hv (Vickers' hardness) 130 or is higher than this value, and the hardness of invar alloy steel sheet material of the present invention is Hv130～250.
In addition, the thus obtained invar alloy steel sheet material that is used for shadow mask carries out quantitative analysis { 100} texture ratio by X-ray diffraction method.This analytical procedure comprised for two steps: the first step determine 111}, 100}, 110} and the diffracted intensity of each texture of 311}, and second step by following given formula calculate the ratio of 100} texture:
100} texture ratio (%)=100 * 100}/[111}+{100}+{110}+{311}] (1)
{ 111}, { 100}, { 110} and { 311} represents the corresponding diffracted intensity of each texture herein.
In addition, can adopt corrosion factor to come the corrodibility of quantitative analysis invar alloy steel sheet material.The method of determining corrosion factor comprises: corrode side surface of steel-sheet, calculate the ratio of depth of corrosion and sideetching then.
Corrosion factor=(depth of corrosion)/(sideetching) (2)
By top formula (2), for depth of corrosion (obtaining corrosion length) at the steel sheet thickness direction by jet etching liquid, little sideetching (the corrosion length on the thin sheet surface direction) shows that the material steel sheet has superior corrodibility, that is to say, corrosion factor is high value; Otherwise big sideetching shows that material plate has poor corrodibility, and promptly corrosion factor is a low value.
Compare by the hardness of measuring sheet of material, can determine its mechanical property.Can utilize the Vickers hardness tester that has 100 gram load to measure hardness.
Example
Explain the present invention in more detail with reference to example below.Invar alloy steel sheet material contains the composition of the Sample A that table 1 provides, and with this alloy melting, casting, forging, carries out uniform heating treatment, hot rolling and pickling then, by this order heat production in next life volume steel sheet.Table 2 has provided the production standard of first cold rolling, annealing and secondary cold-rolling respectively.Table 3 has provided the measurement result of the sheet of material characteristic of producing.Hardness is represented with Vickers' hardness (Hv-100).If the hardness of sample thin plate is Hv130 or higher value, evaluation result is labeled as " possibility ".Because generally speaking, steel sheet passes the corrosion service line with the form of band steel, if therefore steel-sheet hardness does not reach Hv130 or the value higher than Hv130, steel sheet can not be normally by the corrosion service line usually.Per-cent is that { per-cent of 100} texture is if { ratio of 100} texture is 50～80%, and evaluation result is labeled as " possibility ".{ ratio of 100} texture is determined by above-mentioned X-ray diffraction method.For corrosion factor, if the value of corrosion factor is 2.6 or higher value, its evaluation result is labeled as " possibility ".In table 3, zero representative " possibility ", * representative " impossible ".
