Rotary tilting refining furnace The rotary tilting refining furnace is mainly used for the pyrometallurgical refining of recycled metals (mostly used for impure copper). In order to improve the technical and economic comprehensive indicators of the tilting refining furnace, it is best to have a copper grade higher than 90% when entering the furnace. For raw materials with lower copper grades, it is best to first undergo pre-treatment in the blast furnace and blowing furnace before entering the tilting furnace. The furnace body of the rotary furnace is installed on a rotating frame, which, under the action of a hydraulic cylinder, can tilt the furnace body within a certain angle range to achieve process actions such as feeding, melting, and dumping slag. At the same time, the furnace body can rotate around its axis under the action of the transmission mechanism; The rotary motion improves the heating efficiency of the furnace and is of great significance for the overheating of the molten metal. When melting metal in this furnace, a certain amount of slag forming agent needs to be added. The molten slag forming agent and slag liquid have a protective effect on solid and liquid metals, which can prevent metal oxidation The burning loss rate of elements such as silicon and manganese in a rotary cupola is equivalent to that of a coke burning cupola. The content of carbon elements in the rotary furnace is decreasing, so it is necessary to add a certain amount of carburizing agent ( graphite) to the furnace material.
