The performance data are presented for the highly-efcient container glass-melting furnaces. The service condition are defned for the melting tank's lining given that the pull rate being 2,5‒3,0 tons/m2per day and the specifc glass working being 7000‒8000 tons/m2per furnace campaign. The recommendations are given on the fusion-cast baddeleyite-corundum and vibro-cast sintered chromealumina-zirconium refractories using in the melting tank's structural units.Ill. 2. Ref. 18.

Three Phases

A part of a soldier block, placed in a float glass furnace near the hot spot area, was investigated to learn about the changes in the microstructure during the production of the block, during the use for glass melting and after the shut down of the furnace and the cooling of the block. Beside the three phases after the production (baddeleyite, corundum, vitreous phase) during use as a soldier block mullite and secondary corundum as well as secondary zirconia may occure. Cooling down the used block after the furnace campaign the beginning of the crystallisation of feldspars may be seen.

Heating Up

The SIBOR® (Si-10B-2C) oxidation protective coating was applied onto molybdenumand molybdenum – 3 wt% zirconia samples by APS (= Atmospheric Plasma Spraying) with a subsequent heat treatment. Then the coated samples were submitted to ramp oxidation tests with heating rates of 10°C / hour up to a temperature of 1450°C. This procedure simulates the heating up of a glass melting tank where SIBOR® coated parts are most frequently used. Some of the samples which could be oxidized without any defect were then immersed in various molten glasses to determine the dissolution rate of the SIBOR® substrate system. This simulates the situation when the glass melting tank is filled and operated with molten glass. SIBOR® proved to be an excellent oxidation protective coating for the molybdenum – zirconia – material like for pure molybdenum. The coating was fairly good dissolved by opal glass and – slightly less – by soda lime glass. With borosilicate glass a much slower interaction was found. In all cases some discolouration and bubbles were found in the glasses after one week.

Operation Parameters

The float glass melting tank is huge and complex equipment which the operation parameters are difficult to control in production line. The install of desulfurizer makes the kiln more complex and unstable. In present work, we fulfill the field experiments and obtained the optimal practical operation parameters. The obtained parameters were: aperture of wings gate: 75-85%; aperture of draft fan: 30-35% for draft fan 1, and draft fan 2 were through-type; aperture of conveying fan: 70-85%; temperature of gas into desulfurizer: 180-200°C; the water flow were controlled by thermocouple and diaphragm control valve; Velocity of gas into desulfurizer: 8-10 m/s. Our results provide the guidance for installing the desulfurizer and modifying the whole system in practice.
