Method for maintaining crown of kiln

Abstract

The invention discloses a method for maintaining a crown of a kiln. The method comprises the following steps: (1), processing zero inflated silica bricks according to the size of flame leaking holes on the top of the crown of the kiln, wherein the zero inflated silica bricks are matched with the flame leaking holes in size; (2), mounting the processed zero inflated silica bricks on a hanging bracket; and (3), under the environment of non-stop production, hanging the zero inflated silica bricks to the positions of the flame leaking holes, filling the gaps between the zero inflated silica bricks and the crown of the kiln by using a micro-inflated hot repairing mix and curing the micro-inflated hot repairing mix to accomplish maintenance. By adopting the method disclosed by the invention, the repair work can be directly carried out without stop production, corrosion and flake phenomena difficultly occur, and the method is simple to operate and the sealing property is good.

Description

technical field [0001] The invention relates to the field of glass preparation, in particular to a method for repairing the crown of a kiln. Background technique [0002] The glass preparation process requires high-temperature melting, and the furnace is used as a high-temperature melting device for glass. After working for a long time, it is easy to form fire holes on the roof, especially when the holes are large, which is very important for the safe operation and production of the furnace. Stability is a threat. [0003] The traditional hot repair method is to place a cooling "water bag" or a heat-resistant steel plate and then seal it with a hot patch, see figure 2 . The outstanding problem of this kind of sealing method is that after using the "water bag" or heat-resistant steel plate for a period of time, water leakage and melting will occur under the action of high-temperature corrosive gas at 1560°C in the kiln. If it is not found in time, it will damage the kiln bo...

Problems solved by technology

The outstanding problem of this kind of sealing method is that after using the "water bag" or heat-resistant steel plate for a period of time, water leakage and melting will occur under the action of high-temperature corrosive gas at 1560°C in the kiln. If it is not found in time, it will damage the kiln body It will cause certain harm and affect the product quality; in addition, with the increase of fire holes on the roof, the number of "water bag" or heat-resistant steel plate repairs will also increase, and at the same time, it will increase due to the heat absorption of the "water bag" Fuel consumption, steel plate melting and falling into the furnace affect product quality and even erode the fused bricks at the bottom of the pool
