Vacuum Induction Melting Furnace Design

Vacuum Induction Melting Furnace Design

Vacuum induction melting is indispensable in the manufacture of superalloys. Compared to air-melting processes such electric arc furnaces (EAF) with argon oxygen decarburization (AOD) converters, VIM of superalloys provides a considerable reduction in oxygen and nitrogen contents. Accordingly, with fewer oxides and nitrides formed, the microcleanliness of vacuum- melted superalloys is greatly improved compared to air (EAF/AOD)-melted superalloys.

Grinding Steel Ball Heat Treatment Analysis

Grinding steel ball heat treatment typically includes heating, insulation and cooling processes. These steps connect with each other and can’t be interrupted. Wherein, heating is an important step. There are many heating methods for heat treatment. Charcoal and coal are the oldest heat producer, which are generally replaced by liquid or gas fuels. The electricity application makes temperature control easier and no environment pollution. These heat fuels can be used to heat directly or indirectly by molten salt or floating particles.
