Product Description
Specifications and rated gas flow
There are seven kinds of rotary cupola, and the melting time of each furnace is between 60 and 80 minutes, in addition to the time of melting metal, each furnace also needs a certain amount of auxiliary time such as cleaning, feeding, iron, slag and so on.

1. Structure and working principle
Using pure oxygen and natural gas to mix and burn through a burner, a flame of over 2700 degrees Celsius is sprayed out. The furnace wall is heated and during the rotation process, the metal furnace material is heated and melted by conducting heat through the furnace wall.
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 pouring out slag.
At the same time, under the action of the transmission mechanism, the furnace body can rotate around its axis, and the rotary motion improves the heating efficiency of the furnace, which is of great significance for the overheating of the molten iron. When melting metal in this furnace, a certain amount of slag forming agent needs to be added. The slag forming agent and slag liquid have a protective effect on solid and liquid metals, which can prevent metal oxidation.
