Introduction

Alexandr Mikhailovich Marchenko is a prominent inventor based in Kyiv, Ukraine, who has made significant contributions to the field of electroslag remelting technology. With a total of five patents to his name, Marchenko's work focuses on improving methods and apparatuses for producing metal workpieces, particularly in the casting industry.

Latest Patents

Marchenko's most recent innovations include two noteworthy patents. The first patent is titled "Apparatus for electroslag remelting of consumable electrodes." This apparatus features electrode holders for at least two consumable electrodes connected to different terminals of an a.c. power source. It is designed such that the mould and bottom plate are electrically interconnected and linked to the power source through rectifiers. These rectifiers ensure the flow of direct current through the bottom plate and the mould, optimizing the remelting process.

The second patent, "Method for producing a non-split metal workpiece formed as a cast hollow," outlines a sophisticated procedure for creating a non-split workpiece. This method involves pouring premelted slag and metal into a receptacle, followed by electroslag remelting of consumable electrodes within a slag pool. As the materials solidify, a workpiece is formed from two distinct parts, facilitating the production of hollow billets with a bottom section.
