Under certain conditions, the quality and variety of refractory materials even play a key role in the development of new steel smelting technologies. Refractory materials are often ignored because they are called auxiliary materials for the metallurgical industry. In fact, it is closely related to the development of the steel industry. Therefore, to realize the modernization of metallurgical work, we must pay attention to and vigorously develop refractory technology.

The history of the development of steel smelting technology proves that every major technological change depends on the development of new varieties of refractory materials. Refractories are basic materials that serve high-temperature technologies, and are particularly closely related to the development of the steel industry. Without high-quality and new varieties of refractory materials to match it, many new smelting technologies cannot be used for socks. The development of dolomite refractories has ensured the success of alkaline air converters; the appearance of high-load softening point silica bricks is an important factor in the success of open-hearth furnaces; the invention of magnesia-chrome bricks resistant to rapid cold and rapid heat promotes the development of alkaline open-hearth furnaces ; The successful development of magnesia-carbon bricks makes the ultra-high-power electric furnace play a role. In short, refractory materials and steel smelting technology are interdependent, promote each other and develop together.

Under certain conditions, the quality and variety of refractory materials play a key role in the development of steel technology. The refractory industry should develop simultaneously with the steel industry. Some industrially developed countries such as Europe, America and Japan, in the era of rising steel production, all eagerly sought help from the development of refractory materials and the improvement of quality. Modern steel production has stagnated, and resistance is committed to improving quality, expanding varieties, and reducing energy consumption. Higher requirements are put forward for refractory materials. my country's iron and steel industry is in a period of continuous increase in output, while focusing on variety, quality and efficiency, and must devote itself to the development of refractory materials.

At present, my country’s iron and steel industry is in a transitional period to the modernization of production technology. It is suffering from large-scale blast furnaces, coke ovens, converters, and electric furnaces and strengthening of smelting, hot metal pretreatment, converter top and bottom combined blowing, and electric furnaces with ultra-high power. The wide application of new technologies such as external refining and continuous steel casting; with the development of the decomposition technology outside the cement kiln window, the development of the float production process and the large-scale glass bath, refractory materials have become a way to increase the life of smelting equipment and products One of the delivery options for quality, expanding product varieties, and improving economic efficiency. Thus, the refractory industry is pushed to a new stage. Some refractory materials will be developed from traditional "furnace building materials" to "functional refractory materials", and some refractory materials have become one of the components of smelting process equipment. For example: immersion nozzle, shroud nozzle or sizing nozzle for continuous casting; ceramic spray gun and spray metallurgy; bottom air supply brick and top and bottom composite converting converter, etc.

The above-mentioned refractory materials not only require high performance, but also have strict tolerances on external dimensions. The production of such refractory materials, from raw materials to equipment, from production technology to testing methods, must break through the traditional production methods of refractory materials and adopt new high-performance means. It can be seen that the production of refractory materials is facing severe challenges.
