Since 2016, Shanxi Huaze Aluminum & Power Co.
, Ltd.
has increased the technical transformation of equipment, strengthened precise management, and carried out technical research in accordance with the requirements of Chinalco's carbon system to improve the quality and reduce the cost of the transformation and upgrade work to effectively ensure the stable carbon production and make the anode body dense.
And other technical indicators have been greatly improved, with the anode height of 625mm, the anode life cycle has entered the ranks of advanced technology of 34 days
.
The anode consumption rate is mainly related to the anode body density, current density and current efficiency
.
The extension of the anode life cycle is a manifestation of the improvement of the comprehensive management level of carbon block quality and electrolysis production technology
.
Prolonging the anode cycle can not only effectively reduce the consumption of aluminum anode per ton, but also reduce the periodic impact of the pole change operation on the electrolysis production, which is beneficial to maintaining the energy and material balance of the electrolysis cell and improving the current efficiency
.
In the past year, Huaze Aluminum & Power has taken a number of measures to improve the quality of anodes.
First, strictly control the quality of raw materials, strictly follow the standard requirements for sampling and analysis, and resolutely use unqualified raw materials; secondly, solve the production bottleneck problem through technical research and continue to optimize the process , The molding process implements the vacuuming technology transformation of the molding machine to effectively improve the molding effect.
The green anode body density is increased by 0.
04g/cm3, the residual electrode treatment and other processes are added to remove the iron device, the anode ash content is reduced, and the anode reactivity index is improved; and the process is strengthened.
Control, in view of the characteristics of long anode production process flow and many quality influencing factors, strictly control process links, strict operating standards, strictly observe process parameters, and ensure product quality; in addition, regularly visit the electrolysis production site to understand anode usage, adjust process, and optimize The calcination curve increases the final temperature of 1P, increases the final calcination temperature, prolongs the holding time, ensures the homogeneity of the anode, and greatly improves the physical and chemical indexes of the carbon block
