A microwave oven and a double spiral by the method of the microwave oven with a dual spiral submerged arc combined preparation ferromanganese

The present invention relates to a microwave oven and a double solenoid type joint prepared using the microwave ferromanganese furnace with double spiral submerged arc furnace, microwave equipment belonging manganese and metallurgical art. The microwave oven comprises a double spiral tube rack, and a microwave cavity means three double helical stirring portion. The present invention employs the double spiral type microwave furnace manganese ore obtained prebaked hot mass, the hot material is then placed in a submerged arc furnace smelting to obtain ferro-manganese. The tube furnace was heated by microwave, direct rapid heating of the material allows non-contact type; magnetron layout of the reactor, the microwave energy into heat efficiency gains; large number of small power to the magnetron matches the combination to achieve a successful development of industrial production of high-power microwave reactor, the method short production cycle, low energy consumption, to properly resolve the various harmful phenomena caused by cold material into the furnace.
