1. According to the design of the kiln, the operating environment (requirements of ingredients and mixtures, system, atmosphere, pressure, burning flame conditions, etc.) and fire-damaged refractory castables should be selected and the corresponding refractory materials should be treated.
2. Secondly, according to the age of the kiln design and the fire loss rate of each part of the kiln, select refractory castables that can design the age of the kiln to reduce the physical and chemical properties of the kiln, combustion and erosion, and meet the requirements of appearance size.
3. At the use temperature, two different refractory castables that react with chemical substances should be avoided. When necessary, transition bricks or transition layers should be installed between two different refractory masonry. Otherwise, a common melting point will be formed, which will accelerate the combustion and erosion of refractory materials, which will greatly affect the age of the glass kiln.
4. The refractory castable used for contact with glass melt should minimize the transverse brick joints to avoid corrosion. (Especially fused zirconia corundum bricks), otherwise the erosion rate of the material will be accelerated.
5. When building refractory materials, the refractory mortar should be the same as bricks. Different refractory materials and refractory slurries should not be mixed.
6. The selection of refractory castable materials should be economical and reasonable, and the configuration should be reasonable. Choose high-quality refractories as high-grade refractories. Otherwise, it will not only affect the service life of the glass furnace, but also cause great waste and unreasonable rationality.
7. We should be responsible for the technical management of the glass kiln, observe the burning loss and corrosion of the kiln, and find the weak links of the kiln repair, so that the design of the kiln and the selection of refractory materials will be put into the furnace in the future. At the same time, a dedicated person is responsible for the relevant technical requirements of refractory materials, physical and chemical test reports, masonry, kiln drying, maintenance and kiln maintenance, original records, establishment of special files, etc. Accumulate experience and continuously improve the selection and configuration of refractory materials.
