In recent years, the proposal of "double carbon" goal and the large-scale production reform of cement industry, especially the trend of large-scale cement kiln and the normal implementation of peak staggering production, have raised the technical requirements of refractories for cement kiln to a new height. Faced with the weak market demand caused by overcapacity, frequent start-up and shutdown of cement kilns pose a more severe challenge to the stability and durability of refractories.
Li Xiang , general manager of 
Zhengzhou Lifu New Materials Co., Ltd., pointed out in his analysis of the current situation of the industry that the application of traditional castables in key parts of cement kilns often faces problems such as serious wear and tear, and that their service life is difficult to meet the five-year standard expected by the industry because of improper construction or irregular baking procedures. This greatly affects the stability and economic benefits of cement production.
Titanium-aluminum ceramic composite is the main solution at present. This material is known for its high strength and high corrosion resistance in high temperature environment, especially its titanium-aluminum alloy fiber, which can maintain stable performance at high temperature of 1450 ℃, and the steel fiber content of up to 30% in the material further enhances its durability and reliability. 
Li Xiang also pointed out another pain point in cement production, that is, material skinning in the kiln inlet system, which not only affects the ventilation efficiency and leads to unstable production, but also is accompanied by high safety cleaning costs. The introduction
of microcrystalline ceramic materials provides an innovative answer to this question. Its excellent acid and alkali resistance and low chemical reactivity can effectively resist material erosion at high temperature. In addition, its low porosity and smooth surface characteristics significantly reduce material adhesion and ensure the smooth operation of the system. 
Li Xiang emphasized that the application of titanium-aluminum ceramic composite materials and microcrystalline ceramic materials not only solved the problems of short refractory life and poor system stability faced by cement enterprises, but also provided strong support for enterprises to reduce costs and increase efficiency, save energy and reduce emissions, and upgrade equipment.
Looking forward to the future, Zhengzhou Lifu New Materials Co., Ltd. will continue to provide stable and high-quality refractory products for the cement industry, contribute to the high-quality development of the refractory industry, and join hands with cement enterprises to achieve green, efficient and sustainable development.
