A rotary converter consists of a rotary base unit and one or more capacitor panels. The base unit appears similar to an integral horsepower three-phase motor, but with no shaft extending from the endbell. One capacitor panel is connected to the base unit. The panel and base function together to provide three-phase power.
The furnace body of oxygen top-blown converter is comprised of furnace shell, lining, trunnion, and backing ring. The furnace body of converter is intended to contain molten iron for the purpose of oxygenated converting. It is fixed on the seat supported by the backing ring and trunnion, and rotates in positive and negative 360° …
The top-blown rotary converter (TBRC) is a general-purpose unit for copper and precious metals production. A central feature of the TBRC is the constantly high-melting and refining efficiency. For precious metals refining, input materials can include precious metal–containing ores and scrap alloys from other non-ferrous processes. Depending ...
Rotary converters are best used for large applications (10 kVa or more). While slightly harder to install and more maintenance-intensive than solid state converters, rotary converters have numerous benefits. They're easy to troubleshoot and repair. They work well with heavy loads and are flexible in the kinds of loads they can handle.
The top-blown oxygen steelmaking process is a very complex batch reaction course.
