At present, countries and regions such as Europe, Japan, and the United States no longer use chromium containing refractory materials due to mandatory government regulations, and the use of green refractory materials has become an inevitable trend.
In the future, the expansion of refractory materials in cement kilns can benefit from the promotion of similar energy-saving and environmental protection policies. In the field of cement kilns, companies such as Ruitai Technology, Zhengzhou Huawei, Shandong Luzhong, and Yingkou Qinghua have developed magnesium aluminum spinel, magnesium iron spinel, and magnesium iron aluminum spinel bricks, which can be used in the sintering and transition zones of large-scale new dry process cement brick kilns. They have reached or exceeded the service life of magnesium chromium bricks and can completely replace magnesium chromium bricks, Significantly reduced chromium pollution.
In today's increasingly scarce national resources, the development of new green environmental protection and energy conservation and consumption reduction has become the purpose of refractory materials.
The China Refractory Materials Association also believes that during the 12th Five Year Plan period, the development of refractory materials will present new characteristics, based on improving product quality and application level, with a focus on adding or strengthening new connotations, namely energy conservation, environmental protection, and low-carbon. The basic direction of the development of refractory material technology is to take independent innovation as the basic starting point, take the integrated path of scientific design and application of refractory materials, refined and green production and application, consumption reduction and resource conservation, and promote research and development to a new level. The innovative direction of refractory materials used in the cement industry is chromium free and energy-saving.
The understanding and behavior of the concept of green refractory materials should be comprehensively considered under the guidance of systematic concepts. For the refractory industry, scientific and systematic considerations should be taken from various aspects such as raw material preparation, production, construction, application, and post-use treatment, to avoid limiting thinking and perspective to one point or aspect and neglecting the other.
We should focus on the big picture and small aspects, face reality and have a certain emphasis, and vigorously promote the cooperation and coordination among users, production, research and development, and design. As an enterprise, we should strengthen cooperation with research institutions and user units, increase cooperation between industry, academia, and research, and achieve new breakthroughs in the technology of green refractory materials.
