Document Type and Number:
WIPO Patent Application WO/2019/201182
Kind Code:
A1
Abstract:
A cupola furnace employing plasma to perform a melting process comprises a furnace body (1) and a heating source (2). The furnace body (1) has an internal integrated vertical through-channel structure. A material feed opening (6) and at least one molten iron outlet (7) are arranged at the furnace body (1). The material feed opening (6) and the molten iron outlet (7) communicate with each other by means of the through-channel structure. A hearth region and a melting zone of the through-channel structure are configured to be a filled section (11) accommodating high-carbon balls (5) that support a furnace charge (8). The cupola furnace uses a plasma gun as a heating source (2), and employs the plasma gun to inject high-temperature nitrogen plasma into the furnace so as to heat and melt a metal furnace charge. Accordingly, the present invention is more eco-friendly, can be easily operated, eliminates emissions of carbon dioxide and sulfur dioxide, and is particularly applicable to regions having sufficient power supply and low electricity prices, thereby meeting the requirement of developing eco-friendly casting industry.
