Abstract
For efficient operation of high-power aluminum reduction cells with prebaked anodes,full-time monitoring of the main technological parameters is required.This article discusses a multifunctional crust breaker of the automatic alumina feeding system. It provides the alumina supply to the bath by breaking the continuously solidifying crust on the surface of the melt. The multifunctional crust breaker is also a part of the automatic alumina feed system, providing regular automatic measurements of the process parameters.This article describes the development of a laboratory bench with a multifunctional crust breaking device. The goal and objectives are set. The design of the device is presented in the paper. The paper shows the advantages of using an automatic alumina feeding system with the developed multifunctional crust breaker.The positive effect of using the bench in the training process is discussed.
Highlights
The aluminum industry, like any other industry, requires new solutions in the production processesto reduce the cost of the primary aluminum production
An automatic alumina feeding system is installed on a high-power aluminum reduction cell
If the crust is not broken, and the monitoring is not carried out, the continuation of the alumina supply will lead to the accumulation of alumina on the surface of the crust (Figure 2) [13,14]. The existing problems, such as a lack of an automatized acquisition of technological parameters of the electrolysis process and lack of control the process of breaking the crust could be solved by the development of a multifunctional crust breaker for an automatic alumina feeding system of aluminum reduction cell
Summary
The aluminum industry, like any other industry, requires new solutions in the production processesto reduce the cost of the primary aluminum production. These new solutions are becoming even more relevant because of the instability of the world economy.Automation of production processes is one of the priority directions of development in any industry. The current level of automated control of primary aluminum production does not provide timely adjustments to the technological parameters of the electrolytic aluminum reduction process, such as temperature, cryolite ratio, bath, and metal level [1,2]. Acquisition of the process data will increase the effectiveness of the control of the aluminum reduction process. The task of creating an automatic parameter control system is important for the aluminum industry
