Abstract
PURPOSE:To eliminate eneven striping due to the segregation of Ni, Mn, etc., and to produce a shadow mask which is bored by etching with high precision by annealing a hot-rolled Fe-Ni based alloy sheet as the shadow mask for the cathode-ray tube of color television at a specified temp. CONSTITUTION:The ingot of an Fe-Ni based alloy contg. 30-45wt.% Ni and <=5wt.% of the auxiliary component and additive such as Cr, Mn, Co, Ti, V, Nb, Zr, Mo, Al, and W is continuously cast to produce a shadow mask to be used for the cathode-ray tube of color television. The ingot is hot-rolled into a plate having about 5mm thickness, and the plate is placed in a mild-steel box and annealed at 1000-1400 deg.C without the surface being oxidized. The plate is pickled, cold-rolled, recrystallization-annealed, cold-rolled, recrystallization- annealed, and cold-rolled to produce a shadow-mask material having about 0.15mm thickness. The material is bored to obtain a shadow mask capable of being used as a high-precision mask.

By annealing under specific conditions, it is possible to eliminate uneven streaks due to component segregation without any problems. For this reason, etching holes can be created precisely, and continuous casting materials can also be used as high-definition masks, greatly contributing to higher image quality and lower costs of color cathode ray tubes for color televisions and computer displays.
