Investment Casting for Oil and Gas Complex

Abstract

The article considers an advanced method of ceramic mold and rod forming from liquid mixtures on non-organic bonding materials. Their application allows significantly improving the environmental situation and, at the same time, making molds and rods better in terms of their mechanical properties. In its turn, it results in a more precise geometry of the molds obtained. The developed composition allows applying only Russian materials, lowering the net cost comparing with a conventional business of ceramic mold casting (Shaw process) while providing high technological properties of forms and rods.The authors conducted the analysis of the phase composition of technological materials and provided a rationale for possible import substitution.The experimental part of the research work contains two series of experiments; the first one included the selection of the ceramic mix composition by the amount of gelatinization agent. The second series of experiments studied the impact of vacuum processing on the properties of rods after their curing. The authors present experimental precise molds for the oil and gas complex of the Russian Federation.
