Definitions
- the present invention relates to a heat shrink band for a heat shrink band around a panel in a color tube such as a television, and a method thereof.
- Background Leakage Since the inside of the tube is in a high vacuum of l x lO ⁇ Torr, the tube is said to have a function of preventing the panel surface and preventing the tube from rising inside.
- such a heat shrink band also has a function of shielding the ground as well as the inner shield. l ⁇ is prevented from occurring.
- Plain shelf is used as a heat shrink band neo-material, but since the magnetic permeability at the geographical level (approximately 0.3 ⁇ e) is 200 away, the viewability is sufficient and good.
- the position of the rough surface is set to i3 ⁇ 4T.
- the age of the steel sheet of the steel 1 series is a process of hot E, then cold K to make the steel sheet ⁇ 650-900 ° C and ⁇ -250 ⁇ -500C This can be done by a method that performs the steps of “overtime”.
- FIG. 1 is a diagram showing the relationship between the amount of Si and the amount of drift Dh, Bh.
- FIG. 2 is a diagram showing a relationship between z Xt and ground: drift amounts Bh and Bv.
- FIG. 3 is a diagram showing the relationship between the harassment in steel 1 and ti Xt.
- FIG. 4 is a diagram showing the relationship between; ⁇ tun and Xt in steel 2.
- FIG. 5 is a diagram showing the relationship between excessive leaching and Xt in steel 1.
- FIG. 6 is a diagram showing the relationship between excessive reaching and Xt in steel 2.
- FIG. 7 is a diagram showing the relationship between temper ⁇ and / xXt.
- BEST MODE FOR CARRYING OUT THE INVENTION We examined the special factors of a steel sheet that caused a color shift when applying a heat shrink band steel sheet to a power tube, and found that the amount of Si and the geomagnetism It was found that the product X t of the magnetic permeability ⁇ and Na t at the level magnetic field 0.3 O e was observable. The details are described below.
- a 1.6-band steel plate is yielded by hot and cold thighs, and after a difficult time of 60 seconds at 750 ° C, an overtime treatment of 400T: is performed for 90 seconds. After processing for about 60 seconds at 500, which is equivalent to shrink-fitting, it is inserted into a 29-inch TV ItW tube panel, and the terrain drift is evaluated. I asked.
- the drift amounts Bh and Bv are 360 for the CRT with a vertical magnetic field of 0.35 Oe and a water field of 0.3 ⁇ e applied to the CRT. Rotate and observe the position (landing error) of the electron beam's landing point with respect to the »point. From this peak-to-peak value, Bh is determined. Also, the field is 0 ⁇ e, and the vertical magnetic field is 0 ⁇ . Bv is calculated from the value of the position shift when changing from e to 0.35O e. Thus, the amount of dich drift Bh, Bv that is perceived closely is closely related to the storage characteristics, and the smaller these values are, the smaller the color shift is and the more excellent the land drift is.
- Fig. 1 shows the relationship between the amount of Si and the amount of terrain drift. Bh and Bv in the figure are expressed as relative values when the value at the age of 0.1% Si is set to 1.
- C contributes to the strengthening of the steel sheet, but is not preferred for the magnetic permeability, so its content should be 0.1% or less.
- ⁇ has the effect of improving hot ductility and also contributes to the rise of the steel plate by solid solution strengthening. Therefore, TP is set at 0.1%. On the other hand, if the amount of Mn exceeds 2%, the magnetic permeability deteriorates, so the amount is set to 2% or less. The Mn content can be adjusted within this range according to the desired bow level.
- P Contributes to the strengthening of P ⁇ fiber board, and can be supplemented according to ⁇ . However, at an age of more than 0.15%, the steel sheet becomes brittle and causes problems such as coil breakage during cold work. Therefore, its content should be 0.15% or less.
- S is not preferable for both hot ductility and magnetic permeability, so its content is set to 0.02% or less.
- soLAl A1 Since it deteriorates the resistance, the amount is set to 0.08% or less to prevent this.
- N contributes to the strengthening of the steel sheet, but is not preferred for the magnetic permeability, so its content is made 0.005% or less, preferably 0.003% or less.
- C is reduced to 0.005% or less, i is 0.02 to 0.06%, and B is 0.0003 to 0.005%, the solution of C. It hardens as carbides and nitrides, and can reduce the change in magnetic permeability after shrink fitting. Further, it is more preferable to set C to 0.002% or less, Ti to 0.03 to 0.05%, and B to 0.0003 to 0.001%, respectively.
- the upper limits of Ti and B are provided in order to avoid a decrease in the magnetic permeability and ductility due to the addition of the boat.
- Fig. 2 shows the relationship between Xt and the amount of drift in digi.
- Bh and Bv are shown as relative values when the value of the material is set to 1.
- both Bh and Bv are 1.0 ⁇ , which is the same value as that of timber. However, when Xt reaches 350, Bh and Bv t are better than that of timber.
- FIG. 2 is the result of the steel 2 system, but the same result is obtained in the recreational game of level 1 which does not necessarily include i and B.
- ⁇ After performing hot ffi® and cold ffi® under the conditions commonly observed when manufacturing a sheet, In; there are t jong and overtime exclusion.
- Figure 4 shows the relationship between 'X' and H Xt in Steel 1.
- Xt 400 ⁇ ⁇ in the range of 800 to 900. This corresponds to the mouth of the change due to the change of Xt in Fig.3 and Fig.4. 0)
- the temperature is lower than 650 ° C, the recrystallization and the subsequent length are insufficient. It is thought that if the value is too small, and if the value is unfavorable in the range of @ 650 to 900, the value increases with the recrystallization length. If the value exceeds @ 900, it is thought that the crystal force becomes a shelf and the strength is reduced again.
- a 1.2mm steel plate was used, and after returning for 60 seconds at 750, performing a 90-second period between 150 and 550, collecting the link mit without transmutation ⁇ , and shrink fitting. After awakening at the current 500 for 60 seconds, the permeability at the field level magnetic field of 0.3 Oe was reduced. In addition, after 100 hours of treatment at 150 ° C, the customer ratio / dose also changed.
- Figure 5 shows the relationship between the overaging temperature and Xt in Steel 1.
- FIG. 6 shows the relationship between the overheating and Xt in Steel 2.
- FIG. 7 shows the relationship between temper ⁇ and ⁇ Xt.
- the result of FIG. 7 is the result of the steel 2 system, but the same result is obtained in the steel 1 steel system that does not necessarily include Ti and B.
- the heat shrink band may be subjected to plating due to the »ft property, but even in this case, if the characteristics before the plating satisfy the range of the present invention, the characteristics of the face can be obtained. Difficult case 1
- the / ⁇ systems A to G shown in Table 1 were heated to ⁇ , 1200X :, and were heated E to 3.2 3.2mm by finish 820 and winding 680.
- the obtained heat treatment was cooled to 0.8-1.6 mm in Xinjiang, decanted at 500-850 ° C for 90 seconds, and then over-aged at 150-350 for 2 minutes. .
- the steel sheet which had been subjected to the method in which the overpressure and the pressure regulation rate were within the range of the present invention had an Xt of 350 at a magnetic field of 0.3 ⁇ e and a drift of the buried material. It can be seen that 0 is excellent, and that it is good.
- the method out of the scope of the present invention suffers from the problem that the Xt is less than 350, which is inferior in the drifting property, and therefore the fiber process becomes as a color shift wister. nass! O
- the geomagnetic drift properties are as follows: C: 0.03%. Si: 0.03%, Mn: 0.25%, P: 0.015%, S: 0.007%, soLAl: 0.05%, N: 0.0020%, Ti: 0.04%, B: 0.0009 % Of steel, and ⁇ ⁇ 1% temper ⁇ ⁇ is performed by thighing by the 3 ⁇ 4 ⁇ 3 ⁇ 4 method; ⁇ The relative ifi when the ground drift amount of the plate is set to 1.
- the composition, the temperature, and the tempering pressure were determined in such a manner that the temperature was within the range of the present invention. It turns out that it is excellent. In addition, when the overtime is within the range of 250 to 500, the storage characteristics are improved.
- a board controlled by a method out of the scope of the present invention has an Xt force of less than 350 and is inferior in drifting property, and thus has a flat process as a color-shifted fiber.
