Description

The invention relates to the industrial construction materials, in particular, to the production of sheet, container, medical and other types of glass.

The purpose of the invention is to increase productivity, improve glass quality and extend the kiln campaign.

FIG. 1 shows the cooking basin of the stove with the installation of the proposed wall refractory structure in the region of the fourth and fifth steam burners, a plan; in fig. 2 - fragment of the refractory masonry of the wall of the cooking basin With the adjacent refractory structure, plan; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2

In the cooking basin 1 of the bathroom a glass-20 welded glass melt and a glass-forming furnace with a transverse direction of the flame heated by burners 2 (Fig. 1 shows a stove with six pairs of burners, number of burners

comes from the loading pocket 3), has a capacity of 4, improving the quality of the bottom 4 of fireclay bars, fiberglass and extending the work campaign

manufacturing equipment for the production of finished glass.

Thus, the use of isotreni provides an increase in production

rubbed with bakorovaya tile 5, refractory (bakorov) masonry of the pool walls and refractory bars 7 with an increased height and thickness of protrusions in the area of the fire point 8, adjacent to the pool walls.

The invention is applicable to glass furnaces with cooking basins having a length, width and depth, respectively, in the range of 16000-35000; 8000-12000 and 1100-1500 mm.

The indicated standard sizes of the cooking pools correspond to the length of the section equipped with the proposed design in the range of 2000-12000 mm with the height and thickness of the protrusions, respectively equal in the area of the quarter point 250-800 and 250-600 mm and on the remaining fragments of the section 200-550 and 200-500 mm.

The downward branch of the transverse convection currents 9 of the glass mass 10 is localized mainly in the longitudinal sections of the explosives (Fig. 3 and 4), which reduces the activity of the transverse conventional glass flow of direct glass in the near-wall zone 11 and.

therefore, it reduces the rate of corrosion of the walls of the cooking basin in the high-temperature layers of the melt with a corresponding extension of the working campaign of the furnace and an improvement in the quality of the glass by refractory inclusions.

Stronger braking effect of the refractory bars on the transverse convection currents in the zone of the quill point (by increasing the height and thickness of the protrusions in this zone) provides favorable pre-conditions for increasing the temperature barrier in the path of freshly cooked glass melt advancing along the length of the cooking pool and, consequently, for increasing productivity ovens by

manufacturing equipment for the production of finished glass.

Thus, the use of the invention provides an increase in production. The bottom refractory bars are technologically combined with the additional electric heating of the glass melt in the area of the fire point.
