Continuous and adjustable glass fusing process using a tunnel-furnace and the tunnel-furnace used for this process

摘要

This invention is characterized by the construction of a furnace, divided into three broadly differentiated phases and zones; and with independence of the means of conveyance assigned to each one, in seven different stages, two of heating in the first phase, one of rapid cooling in the second phase and two others of after cooling in the third; apart from two more, whether outside the furnace or combining an additional module, until reaching ambient temperature; with a total process time of between two hours and a half and four and a half hours, as well as with different temperatures, and whose upper limit doesn't exceed 880 DEG C.
