Abstract:
     The separately-loaded recombustion cupola furnace is a kind of successively melting equipment for casting. The furnace body consists of a main shaft, a recombustion section and preheating section. The recombustion section is disposed between the other two sections. At the interface between the recombustion section and the main shaft, one or more recombustion tuyeres are installed. The combustion process is composed of interconnected double-combustion zone. The melting process is a kind of two-section overheating process. The height of the bottom coke is taken as a structural parameter. The method of loading iron and coke separately is used in the loading of fuel which may be casting coke or various non-coke fuel. Because of the high temperature of the molten iron tapped from the furnace, the stable metallurgical quality, the high thermal utilization ratio of the fuel and the little pollution, the said furnace is one of the excellent non-coke cupola furnace.
