Stand assembly of a glass-furnace bottom

“BKO” JSC has perfected an assembly-stand technology for the elements of a glass-making furnace, first and foremost, the furnace bottom. Coordinated studies were performed to ensure that the accuracy of the stand meets the requirements: a stand with planarity deviations ± 0.5 mm was designed and built, the preparation technology (cutting and grinding) for the block articles for the assembly stand with minimum admissible deviations (linear dimensions ± 0.25 mm; inclinations less than 0.2 mm) was perfected, and the assembly stand technology itself was perfected. The technology developed was used to assemble other elements of the furnace: feed pans of the glass-forming machines, regenerator arches, and loading hoppers. An assembly stand makes it possible decrease substantially the assembly time of a glass-making furnace, lower the construction costs, and develop favorable conditions for laying other elements of the furnace, all which taken together increase the service life of a furnace.
