The temperature of anode baking crane is the main object of industrial control
Firstly, this paper describes the roasting mechanism of anode baking crane in detail, briefly introduces the working principle and structural composition of anode baking furnace, and summarizes the production process of anode baking multifunctional unit. The development of anode baking technology at home and abroad is summarized, and the practical significance of anode baking furnace controller is analyzed. This paper puts forward a comprehensive idea to carry out the theoretical research on the temperature controller of anode baking furnace in China, and takes this as the research idea of this paper to carry out the corresponding research work. The temperature of anode baking multifunctional unit is one of the main objects of industrial control. In the process of industrial production, it is often necessary to control the parameter of temperature. Good temperature control can not only improve product quality, but also reduce energy consumption and improve production efficiency.
In order to better understand the corrosion mechanism of refractory used in anode baking crane flue, the corrosion of sodium gas and carbon monoxide in used samples and under laboratory conditions were studied. Through the corrosion resistance test, it is found that sodium rich glass phase is formed in the corroded samples around the anode baking multifunctional unit. Mullite Andalusite in the refractory matrix reduces the glass phase formed during sodium gas corrosion. In order to improve its corrosion resistance, suggestions are as follows: adding a small amount of andalusite and activated alumina to the raw materials to form secondary mullite phase) reducing the content of clay to reduce the formation of glass phase) optimizing the sintering temperature.
Roasting is an important process in the production of pre baked anode in aluminum electrolysis industry. The roasting process directly determines the quality of roasted anode, which affects the electrode consumption, current efficiency, energy consumption and so on. Therefore, how to improve anode roasting technology and improve anode quality has become an important topic in aluminum electrolysis industry. It is an inevitable way to achieve this goal to intensify the in-depth and systematic research on the basic theory of anode baking furnace. This is also the urgent need to develop and design the anode baking furnace controller with China's independent intellectual property rights. This topic is mainly aimed at the second phase expansion project, the research of combustion controller.
