METHOD FOR OBTAINING RESTRUCTURED ZINC Russian patent published in 2021 - IPC B22D13/00 B22D27/08 

Abstract RU 2763366 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy. The method for obtaining restructured zinc includes processing molten zinc weighing from 70 to 300 kg in a controlled atmosphere at a temperature in an inert gas chamber of 500°C and constant pressure. The mold for pouring and processing molten zinc is a cylinder with a radius of 210 mm, rotating at an angular speed of 8600 rpm around its axis. A hot gaseous agent is introduced into the cavity of the said cylinder with preset time values ​​of flow rate and temperature, and the overload coefficient is provided in the range from 2000 to 10000 G. Then, the temperature in the chamber is naturally lowered to 22-23°C for 10 minutes with simultaneous crystallization of the melt.

EFFECT: improvement of purity of restructured zinc, change of its structure, properties and electron density with an increase in its chemical activity.
