The service life of a glass electric furnace, generally called the kiln age, also refers to the furnace shutdown and overhaul period, and is an important design parameter of the electric furnace. Glass electric furnaces mainly include refractory materials and electrodes, transformers, control cabinets, etc. The main reasons that affect its service life are as follows: 1. It is related to the structure of the furnace. Different formulas are suitable for different furnace types. The main reason is to consider the erosion of refractory materials by the forced convection of glass in the electric furnace. By designing an appropriate structure, ensuring the corrosion resistance of the refractory materials in various parts, especially the lining bricks, is an important factor in ensuring the life of the electric furnace. 2. It is related to the material of the refractory material. In terms of the life of the kiln, high-grade refractory materials are preferred. In terms of design cost, the appropriate materials are first selected based on the design life, especially refractory materials of different materials according to different parts. Materials, such as cast electro-fused 33#AZS for the furnace bottom, but non-shrinkage cavity electro-fused 41#AZS are used for the liquid holes and electrode bricks. 3. The arrangement of electrodes is also one of the reasons that affects the kiln. First of all, the insertion method of the electrode has a great influence. For example, the top-insert electrode can extend the life of the kiln because there are no electrode bricks, but it is relatively easy to form a hot roof or has higher requirements on the shape of the material surface, and the electrode is easy to break: while the bottom-insert electrode The corrosion of electrodes is relatively small, but the design and equipment requirements are high. The corrosion of flat electrode bricks is greater. If there are no special means, the corrosion of the kiln will be greater, so there are higher requirements for operation and use. 4. Material volume is also one of the factors that affects the life of the kiln. Different materials have different impacts on fused bricks and electrodes. For example, ordinary soda-lime glass electric furnaces have a long service life, while furnaces containing titanium, barium, and fluoride have a shorter service life. 5. Reasonable and normal maintenance with the manufacturer is also a big factor. In particular, the manufacturer's timely treatment of the redness of the furnace body and the leakage of material in the brick joints is one of the ways to extend the life of the kiln. Generally, the service life of a kiln refers to the cold furnace overhaul period, and during this period, small-scale thermal repairs may be carried out, such as commonly used measures such as brick patching, tiling, and forced cooling. 6. Use the electrode water jacket correctly. Since some electrode water jackets are difficult to replace, especially bottom-inserted electrodes, severe water jacket leakage may lead to furnace shutdown. The water jacket and softened water should be inspected and maintained regularly, and water interruption is strictly prohibited. After a period of use, shifting and changing the water jacket and electrodes is also one of the means to extend the kiln and equipment. To extend the life of the kiln, production operations must be strictly carried out in accordance with the process and thermal system of the electric furnace to avoid large fluctuations in output, frequent material changes, multiple power outages and water outages, and pipe; production operations to avoid large output Amplitude fluctuations, avoid frequent material changes, avoid multiple power outages and water outages, and avoid improper management
