Title:
COKELESS CUPOLA FURNACE AND METHOD OF MELTING IRON USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/201183
Kind Code:
A1
Abstract:
A cokeless cupola furnace 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 heating source (2) is a natural gas burner. A nozzle (21) of the natural gas burner is arranged at the furnace body (1) and positioned at the high-carbon ball (5)-filled section (11). In the cupola furnace, high-carbon balls (5) function as a material-supporting column in place of a water-cooled grating and a bed of refractory balls, thereby preventing potential safety risks caused to equipment by a water cooled grating, and preventing loss of heat to cooling water in a steel pipe of the water cooled grating.
