Quick age hardening device and method of positive plate for electrolysis

Abstract

The invention discloses a quick age hardening device and method of a positive plate for electrolysis. The quick age hardening device comprises a constant-temperature chamber, heating sources, a temperature controller and a temperature measurer, wherein the heating sources are mounted at the lower parts of three inner side walls of the constant-temperature chamber; the temperature controller is mounted at the outer side of the constant-temperature chamber; the temperature controller is connected with the heating sources; the temperature measurer is mounted in the constant-temperature chamber; the temperature measurer is connected with the temperature controller. The quick age hardening method comprises the following step: standing a cast positive plate blank in an environment of 100-120 DEG C for 20-40 minutes. According to the invention, the constant temperature effectively ensures quick age hardening of a lead alloy positive plate for electrolysis, and improves the product quality; moreover, the time is shortened from the original 7-10 days to 30 minutes, thus greatly shortening the production cycle and improving the production efficiency.

Description

technical field [0001] The invention belongs to the field of hydrometallurgy, and in particular relates to a rapid aging hardening device and method for an anode plate for electrolysis. Background technique [0002] After solid solution treatment of alloying elements, a supersaturated solid solution is obtained, and when placed at room temperature or heated at a low temperature, the second phase precipitates from the supersaturated solid solution, causing significant changes in strength, hardness, and physical and chemical properties. The process is called aging. It has been confirmed by research that the essence of aging strengthening is that many very fine precipitate particles are precipitated from the supersaturated solid solution (usually metal compounds, or the solute atoms in the supersaturated solid solution may gather in many tiny areas), forming some small particles. The solute atom enriched region. When solid solution treatment is performed before aging treatmen...

AI Technical Summary

Problems solved by technology

There are two problems in this method, one is that the performance of the alloy plate is inconsistent as a whole; the other is that the strength of the alloy is difficult to meet the process requirements, which eventually causes problems such as low hardness, easy fracture and short service life of the product, and the storage time is too long.
