METHOD MANUFACTURING INNER SHIELD FOR COLOR CATHODE-RAY TUBE AND INNER SHIEID MADE BY METHOD THEREOF

摘要

The present invention, the method of the inner shield by a method of manufacturing a color cathode-ray tubes the inner shield and the method includes the steps of casting the shield raw melt (raw material melt windshield); The step of rolling the cast raw shield to have a thickness of less than 0.10 mm; The method comprising annealing process the raw sheet metal shield; The method comprising annealing process the annealed raw shield sheet above the recrystallization temperature; Preparing a raw sheet by said shield inner shield of the magnetic shield shape; And the step of processing the film blackening the inner shield; includes.
