摘要： A tension mask frame assembly for a color CRT includes a pair of first and second support members separated a predetermined distance from each other, first and second elastic members installed at end portions of the first and second support members to support the first and second support members, a tension mask installed at the first and second support members such that a tensile force is applied to the first and second support member and having a plurality of electronic beam passing holes formed therein, and a compensation portion installed at the end portions of the first and second support members to make the tensile force applied to the tension mask after heat treatment distributed such that tension at a central portion is greater than that at a surrounding portion.

摘要： A method for manufacturing a thin cold rolled inner shield steel sheet for use in a braun tube is disclosed. With this method, a steel sheet with superior magnetic field shielding properties can be manufactured by carrying two steps of cold rolling without adding an expensive alloy element, and without using a special decarburizing facility such as OCA. The method includes the following steps. There is prepared a steel slab composed of, in wt %, 0.0025% or less of C, 0.05-0.25% of Mn, 0.05-0.15% of Si, 0.015 or less of Al, and a balance of Fe and other impurity elements. Then a hot rolling is carried out on the steel slab at a temperature of 910° C. or above. Then a first cold rolling is carried out, and a first annealing is carried out at above a recrystallization temperature. Then a second cold rolling is carried out at a reduction ratio of 25-45%.
