Converter for producing calcium aluminate refining slag

The invention relates to the technical field of calcium aluminate processing, in particular to a converter for producing calcium aluminate refining slag. The heating furnace comprises a furnace body of a tubular structure, a tail cover is arranged at one end of the furnace body, the bottom of the tail cover is communicated with a discharging pipe, and a heating device extending into the furnace body is fixedly arranged on one side of the tail cover; a material lifting mechanism and a material transferring mechanism are arranged in the furnace body. The material lifting mechanism is fixedly arranged on the inner side of the furnace body and located at the end of the primary heating area and the end of the secondary heating area. According to the converter for producing the calcium aluminate refining slag, the interior of the converter body is divided into the primary heating area and the secondary heating area, so that raw materials can be transferred to the starting end of the secondary heating area through c
