SYNCHRONOUS STABI/FRIT PROCESS FOR CRT, AND FURNACE DEVICE THEREOF, AND SINGLE TYPE FIXTURE THEREFOR

摘要

The present invention provides a simultaneous stabi frit process of cathode ray tubes for manufacturing cathode ray tubes at lower cost, and an integrated fixture with the furnace apparatus.;The present invention includes a heating step of heating the frit panel and the funnel and the stabbi panel interposed in frit glass on the seal surface at the same time in a furnace to frit temperature; A frit holding step of maintaining the frit panel, the funnel and the stab cost panel at a frit temperature after the heating step; A first slow cooling step of gradually cooling the frit panel, the funnel and the stab cost panel to the stabby temperature after the frit temperature holding step; A step ratio temperature maintaining step of maintaining the frit panel, the funnel, and the stab cost panel at a stabby temperature for a predetermined time after the first slow cooling step; And a second slow cooling step of gradually cooling the frit panel, the funnel, and the stabiol panel to room temperature after the stabi temperature holding step, and performing the stabilization / frit process of the cathode ray tube and the process thereof. It provides a furnace unit and an integrated fixture. The top of the furnace is maintained at the frit temperature and can be maintained at the stabby temperature of the furnace. As a result, the staby process and the frit process can be carried out simultaneously, eliminating the need to pass two long furnaces, and the manufacturing process can be shortened as well as the equipment cost and maintenance cost of the furnace. There is an effect such as.
