Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of glass melting furnace, in particular to a paving structure for glass melting furnace. BACKGROUND
[0002] In recent years, with the rapid development of glass manufacturing industry, there is a higher requirement for the service life of glass melting furnace. The phenomenon of high-temperature glass liquid leakage occurs in glass furnace every year, and the leakage position is more common at the bottom of the glass furnace pool, which brings huge economic losses and great safety hazards to the producers.
[0003] In the prior art, in order to prevent the leakage as much as possible, the bottom of the glass furnace is often arranged with a single layer of paving brick structure. Most of the current paving bricks are made of AZS or fused corundum refractory material, which has a certain expansion rate at high temperature. In order to prevent the high-temperature glass liquid from entering the gaps of the paving bricks, expansion joints are not arranged between the individual bricks, but the bricks are placed in close contact with each other, and expansion joints are arranged at intervals for expansion, so as to prevent the paving bricks from being squeezed or bulged by the expansion pressure.
[0004] However, in actual use, the expansion space of the paving bricks may be smaller than the width of the expansion joint, which may cause glass liquid leakage and affect the quality of the glass liquid. Therefore, it is necessary to cover the expansion joint with a pressure joint brick to prevent the glass liquid from flowing into the paving bricks. However, the pressure joint brick is generally made of the same material as the paving brick and also needs to have an expansion joint. After the glass melting furnace is operated, the actual expansion direction is not fixed, and some may expand tightly, while some may leave a larger gap, so that the glass liquid may leak into the expansion joint of the paving bricks, thereby seriously shortening the service life of the bottom of the furnace pool.
