Metallurgical Industry: They are used as furnace lining material. The product can resists high temperature, will not soften or deform at high temperature. The excellent chemical stability can resist the erosion of slag, extend the life of blast furnace for a long time. In addition, high-temperature molten metal also causes very great abrasion to the inner surface of the pipeline. If the inner surface is lined with Al2O3 Ceramic Wear Resistant Tiles, the abrasion will be prevented and the conveyance of the metal conveyance pipeline can be guaranteed.
Power Industry: In the coal mill of coal fired power station, the coal is pulverised by the inner surface of the equipment during the process of coal pulverising. The abrasion caused by the high speed rotation of equipment components reduces the service life of the lining of conventional coal mills greatly, and causes frequent maintenance. While, if they are used as lining, the abrasion is greatly weakened. The hardness of Al2O3 Ceramic Wear Resistant Tiles can resists abrasion of coal particles. The wear resistance is several to dozens of times that of ordinary carbon steel. The equipment wear is greatly reduced. The maintenance cost and equipment downtime are reduced and the power generation efficiency is improved.
Cement Industry: In the cement mill, the abrasion caused by abrasion of the inner wall of the mill body and abrasion of grinding components are very serious. Lining plates and grinding media fabricated from Al2O3 Ceramic Wear Resistant Tiles can greatly improve the wear resistance of cement mill, reduce the frequency of maintenance and reduce the cost. According to the feedback from customers of Shandong Qishuai Wear-Resistant Equipment Co., Ltd., the maintenance times of the equipment of cement plant using Al2O3 Ceramic Wear Resistant Tiles is reduced by 30%–40%. The equipment service life is extended by 2–3 times, and then the production efficiency of cement plant is improved, and the cost of operation of cement enterprise is reduced.
To give you a more intuitive and comprehensive understanding of the indicators used in the performance of Al2O3 Ceramic Wear Resistant Tiles, we have compiled the specification parameter table below.
