Method for replacing pool wall brick of glass melting furnace

Abstract

The invention belongs to the technical field of melting furnace maintenance, and particularly relates to a method for replacing a pool wall brick of a glass melting furnace. The method comprises the following steps: S1: providing a new pool wall brick and a new cushion brick, and preheating the new pool wall brick; S2: reducing the height of the surface of the glass liquid in the melting furnace in which the old pool wall brick is to be replaced, forming an opening in the old gap brick at the upper end of the pool wall of the melting furnace, and then injecting the cooling liquid into the glass liquid through a liquid injection pipe through the opening and cooling the glass liquid; S3: removing the old pool wall brick and the old cushion brick at the glass liquid after the glass liquid iscooled and solidified; S4: loading the new cushion brick, vertically arranging the preheated new pool wall brick on the new cushion brick, and fixing the assembled new cushion brick and the new pool wall brick through a fixing mechanism; S5: repeating the steps S2 to S4, and gradually completing the replacement of the old pool wall bricks and the old cushion bricks to be replaced, so that the service life of the melting furnace is effectively prolonged, and more economic benefits can be created for the melting furnace.

Description

technical field [0001] The invention belongs to the technical field of melting furnace maintenance, and in particular relates to a method for replacing pool wall bricks of a glass melting furnace. Background technique [0002] During the use of the glass melting furnace, the pool wall will become thinner due to gradual erosion. Generally, the original pool wall thickness is 250mm. Because the temperature of the upper layer of the molten glass is higher, the upper part of the pool wall is often used for about 3 years. It will be relatively easy to be eroded and thinned over time, so it is necessary to tie pool wall bricks on the pool wall to prolong the service life of the furnace. Wind cooling, so the thickness of the pool wall bricks tied should not be too thick. Generally, pool wall bricks with a thickness of 75mm are used for use. In this way, the pool wall bricks tied once can generally prolong the service life of the furnace for about one and a half years, while 900 ton...
