Development of technology for high-strength cast iron for manufacturing D49 head of cylinder

Abstract

This article discusses the technology of melting high-strength cast iron with a spheroidal graphite shape intended for the D-49 type cylinder lid by modifying with magnesium (Mg) in the ladle and gating systems. Today, it is very important for the Republic of Uzbekistan and the CIS countries to create and improve high-strength cast iron production technology to prepare high-responsibility parts of railway transport. Improvement of the mechanical and operational properties of cast iron parts with high strength, as well as development and improvement of the casting technology of the D49 type diesel engine head imported from the CIS countries under local conditions.
