Iron and steel industry, calcium carbide industry, alumina industry, refractories are large lime consumption. The past two years, these industries are high-speed development, the growth rate of annual output is more than 20%. Large lime rotary kiln adopted the modern technology can make full use of the cheap energy, especially can use environmental pollution gas as as the main energy. which not only can protect the environment but also produce good quality lime. To use this new technology will increase economic benefits significantly. This paper explained the technical innovation and problems encountered in the development of lime rotary kiln in 2015 and forecast the technical development of rotary kiln in 2016.
In the past year, the market of lime rotary kiln has not changed much, but the enterprise of the lime rotary kiln and the staff technology tend to mature, which promots the innovation and development of the lime rotary kiln. For example, optimizat selection of refractory material, the reasonable configuration of raw materials and fuel process parameters, the production and operation of the level of continuous improvement. But the development of the kiln still exist some problems. In recent years, with the opening of lime rotary kiln production technology, the phenomenon of the malicious competition appeared along with promoting the development of technology continuously. The malicious competition can lead to the decrease of the quality and the technology of lime rotary kiln。
From the national industrial policy and the development of lime rotary kiln in 2015, we can forecast that lime rotary kiln will not have a big development in 2016. However, some intelligent upgrade of steel mills, calcium carbide plant will inevitably lead to the upgrading of the upper reaches of the lime industry. At the same time lime rotary kiln is also sure to develop rapidly in the direction of intelligent to coordinate with the development of the steel plant and calcium carbide plant. Prospects for 2016, lime rotary kiln has great room for development in the aspects such as waste heat utilization, technological transformation, intelligent development.
