Application of magnesia alumina brick




With the continuous development of China's cement industry, higher requirements are put forward for refractories. The refractory industry, which depends on the extensive economic growth mode for a long time, should strengthen the adjustment of magnesia carbon brick for electric furnace to meet the needs of the new situation.




There are some problems in the refractory industry of China's cement industry, such as low industry concentration, vicious competition shortage of raw material resources. Only by speeding up the reorganization integration of refractory production enterprises for cement kiln can we adapt to the rapid development of cement industry. At the same time, enterprises should also strengthen the cooperation with scientific research institutes user units, increase the cooperation between production, teaching research, achieve new breakthroughs in the technology of green refractories, strive to make substantial breakthroughs in some key green refractory technologies application in a short time.

The development of green refractory strategy is related to the current future sustainable development of refractory industry in China.




the coming "refractory raw material industry access standard" will promote the elimination of backward production process equipment, the cultivation of leading enterprises, the development of the industry to a large-scale intensive direction.




Of course, the development of green refractory materials at the same time, product quality must be guaranteed. The main reasons for the low service life of refractories are the backward production equipment of the manufacturer, the low automation level in the process of batching, molding, firing inspection, the product quality fluctuates greatly, the size deviation is large, the masonry method is improper. In use, in order to prevent the refractory falling brick, excessive use of steel plate locking, resulting in a large expansion of refractory material in the temperature rise, excessive pressure damage the refractory brick, low level of fine management.




In order to solve the problem of short service life of refractories, some enterprises have begun to develop energy-saving products, such as replacing magnesia alumina spinel bricks with high thermal conductivity with silicon carbide bricks (high alumina silicon carbide materials), so as to reduce heat loss, reduce heat consumption per ton of clinker save energy. In addition, magnesia iron spinel brick is used instead of direct magnesia chrome brick in rotary kiln, which can effectively avoid chromium pollution.




In fact, cement enterprises should reasonably refractories according to the process conditions of cement kilns the requirements of raw clinker fuel. For example, high alumina bricks with high strength, small thermal expansion rate good thermal shock resistance should be selected to reduce the damage to refractory materials during heating. At the same time, it is necessary to optimize the design scheme, improve the level of fine management, improve the operation rate of cement kiln reduce the consumption of clinker per ton of refractory materials.




At the review meeting of "Specification for use of refractories for cement rotary kiln" organized by China Building Materials Federation, the experts attending the meeting passed the draft standard after deliberation unanimously approved. It marks the successful completion of technical specifications standards for the use of refractories for cement kilns at home abroad. It will be of great significance to promote the standardization of refractories for cement kilns, promote the development of the industry the transformation upgrading.
