Introduction

Abstract

The history of steel castings is associated with previously developed technologies for obtaining castings of bronze, copper and cast iron. These formed the basis for the improvement and development of casting technology of metal with a higher melting temperature and higher mechanical properties, and then - better utility properties (corrosion resistance, impact toughness at low temperatures and finally - smelting in a vacuum). The development of steel smelting technology and methods of obtaining steel castings have been presented against the background of extremely extensive literature on bronze casting in ancient times.
