Rotary metal melting

Rotary metal melting furnaces are devices for melting and casting metals such as lead, zinc, tin, and copper in low tonnage. In lead and zinc ores, these furnaces are usually used for melting and casting metals. Which includes a horizontal tube that rotates slowly around the horizontal axis. The advantages of these furnaces include cheapness, easy operation, the ability to use fossil fuels in metal melting, and low electricity consumption. The biggest drawback of rotary melting furnaces is the creation of more dust than induction and electric arc furnaces, as well as the possibility of more oxidation of the molten metal than induction and electric arc furnaces.

Rotary metal melting is a process used in the foundry industry to treat molten metals. During this process, gas is injected into the melt through a rotating impeller, which provides evenly distributed, small-sized gas bubbles. These bubbles can effectively collect solute hydrogen and entrained inclusions from the liquid metal. The process is used in aluminum scrap melting processes.

Rotary melting furnaces can be made as one open end or two open ends. Their heat insulation cover is usually done using chamotte firebricks, aluminum, magnesite bricks or firecment cement.

The type of fuel for rotary melting furnaces may be methane gas, diesel, fuel oil or a combination of diesel and methane.
