A tilting furnace, such as a rotating furnace, is a versatile piece of equipment used in metal melting processes. It is designed to handle a wide range of metals, including base metals like copper, aluminum, iron, and steel, as well as precious metals such as gold, silver, and rhodium. The furnace's ability to tilt allows for efficient pouring of molten metal into molds or other containers. The melting process is influenced by the furnace's design, heating method, and the specific melting points of the metals involved. Understanding these factors ensures the furnace is suitable for the intended application.
