The melting glass manufacture device, melting glass manufacture manner and production manner of the plate glass which uses those

摘要

Although high quality the no-alkali glass is produced, the melting glass manufacture device which is suited, melting glass manufacture manner, and the plate glass production manner which uses those are offered. When as for this invention being the melting glass manufacture² device because the temperature T where glass viscosity becomes with 10 [dPa S] produces the melting glass of 1500 - the 1760 , the said melting glass manufacture device has the dissolved vessel, as for the aforementioned dissolved vessel, possesses multiple 1st babura where is provided on higher-level side than multiple 2nd babura and said 2nd babura, designating the length of the melting glass channel of the aforementioned dissolved_F vessel as L, distance to the string of aforementioned 1st babura to be 0.4L - 0.5L from the high-level edge of the aforementioned_F melting glass_F channel, aforementionedDistance to the string of aforementioned 2nd babura is 0.45L - 0.55L from the downstream edge_F of the melting glass_F channel, distance L in the string of aforementioned 1st babura and the string of aforementioned 2nd_P babura is 500 - 1000mm, distance L of the direct closely burner is 0 - 2000mm on high-level side in the string and the said string_B1 of aforementioned 1st babura, the melting glass which features that distance L of the direct closely burner is 800 - 2500mm on downstream side_B2 in the string and the said string of aforementioned 2nd babura,_B2B1 at the same time, is LLIt regards the production device.
