Extending the service life of refractory materials for glass kiln, that is, extending the kiln age of the kiln, can increase the medium melting rate of the kiln, reduce non-production time and repair kiln costs, thereby increasing the output value and benefits of the plant. Can be considered from the following links.
(1) In the initial design of the glass kiln lining, the structure and material selection should be reasonably designed according to the thermal principle and design principle, especially to avoid or reduce the scouring of the flame. For example, the chest wall should try to avoid the scouring of the blasting flame. The top of the small furnace mouth and the regenerator should be prevented from scouring. The holes in the kiln should prevent the overflow of the flame; properly reduce the thermal intensity of the flame space and reduce the temperature of the inner surface of the kiln; Reduce horizontal seams to avoid local overheating. Do not have eddy currents or dead angles in the smoke stroke to avoid local overheating and burn the kiln.
(2) The construction process should comply with the construction rules and masonry requirements to ensure the construction quality. In particular, it is necessary to pay attention to the careful selection of bricks. If there are cracks in the corners, try not to use them. Try to process the surface of the bricks that are in contact with the flame or glass, and knock the masonry. Avoid damage to the bricks.
(3) According to the heating curve and feeding plan of the roasting kiln, it should be put into production safely and quickly. Pay attention to several key temperature sections, and heat up carefully to prevent refractory masonry deformation, brick cracking or falling off; basic guarantee of masonry energy Free expansion, timely adjustment of the brace to avoid deformation of the refractory masonry or deformation of the steel structure; excessive fire should be especially careful to prevent the temperature from rising too fast.
(4) Operational procedures and post responsibility system should be implemented in the operation. Strictly maintain the normal operation system of the kiln, such as temperature system, pressure system, liquid level system, atmosphere system, etc., and must not exceed the allowable fluctuation range; often check for erosion, blockage and leakage, especially weak parts, such as feeding Mouth, fluid hole, fire vent, liquid pool wall, upper lattice, flue, etc., in order to find problems in time; strengthen maintenance and maintenance of kiln body damage, such as liquid pool wall, fluid hole, The blasting port, the feeding port, etc. need to be blown by cold air cooling, thermal instrumentation (regular inspection, so that the measured data is accurate and reliable); the hot repairable parts are as hot as possible.
