Green, Energy-Saving Refractory Materials are the Mainstream of Future Social Development
With the global promotion of environmental protection and the development of a low-carbon economy, it is imperative to develop energy-saving, environmentally friendly and eco-friendly refractories, which are important basic materials for high-temperature industries.
High performance: Increasing the development of high-tech, high-value-added unshaped refractory materials is the key to its further promotion and application. Oxide-non-oxide composite refractory products are one of the hotspots of refractory research and development today. At present, the preparation of oxide-non-oxide composite products is the process of shaping products, and the atmosphere is controlled during firing. This method has a complicated process, a large investment in equipment, and it is difficult to meet the requirements for producing large-scale and special-shaped products. As far as the forming itself is concerned, the vibration method is more reasonable than the press method. Because the vibration method facilitates a certain rearrangement of the particles and tends to be densely packed, so as to achieve densification under a small external force. The casting method not only achieves close packing, but also forms pore channels after volatilization of the water added in the mixture, which is conducive to the in-situ carbonization/nitridation reaction involving gas phase, and is conducive to improving the conversion rate of non-oxide and obtaining non-oxidation. A composite material with better development of the material network and a more reasonable structure. Therefore, the preparation of in-situ non-oxide composite functional refractory materials by casting method is an important way to realize functionalization and high performance of unshaped refractory materials.
The main users of refractory materials and the refractory industry itself are high energy-consuming industries and are the key targets for energy conservation and emission reduction. Energy-saving refractories are a kind of green refractories with great development vitality. We should focus on the development of unshaped refractories, energy-saving raw materials, high-performance lightweight aggregates and products, and unburned bricks.
In response to the new situation, new changes, and new contradictions faced by the refractory industry, while expanding and strengthening the main refractory industry, it must transform to a diversified industry, so that enterprises can continue to grow bigger and stronger. Small businesses should gradually switch to production
