Aluminum Melt Furnaces: Principles of Fuel Economy by Al Kennedy, Kennedy Eurotech, Inc. oilfired furnaces for melting and holding aluminum. Because there are so many different types a pot or crucible, and a similar pump may be used for this purpose. Electromagnetic Pumps. Crucible furnaces are one of the oldest and simplest types of melting unit used in the foundry. The furnaces uses a refractory crucible which contains the metal charge. The charge is heated via conduction of heat through the walls of the crucible. crucible melting furnace pdf Design Analysis of an Electric Induction Furnace for Melting Aluminum Scrap K. C. Bala Mechanical Engineering Department, Federal University of Technology Minna, Niger State, Nigeria The shell is the outer part of the furnace. This houses the crucible and the inductor coils, and has higher thermal capacity. It is made of

furnace, heat is created by burning a fuel such as coke, oil or natural gas. The burning fuel brings the interior temperature of the furnace above the melting point of the charge material placed inside. This heats the surface of the charge material, causing it to melt. Induction furnaces produce their heat cleanly, without combustion. crucible melting furnace pdf melting applications, the melting technologies and developments discussed in this report are in general applicable to all furnaces and molten material processes, including primary aluminum, secondary aluminum, glass, iron and steel, and other industries. A crucible assembly for use in induction melting furnaces utilizes an inner crucible formed of partially stabilized zirconia and an outer support member formed of a sintered alumina. The crucibles are in the shape of a cylinder with a closed bottom wall and in the cylindrical wall area, the inner crucible and the outer support member are separated by a layer of porous ceramic fibers of alumina Continuous Aluminum Melting and Holding Crucible Furnace Yusuke Sanoand Masahiro Kuritani NIPPON CRUCIBLE Co. , Ltd. Abstract We have developed the continuous aluminum melting and holding crucible furnace which is compact and it has made a continuous melting possible with a graphite crucible. It combines the features of a tower type melting The crucible type furnace design allows for easy alloy changes while the speed of gasfired melting permits rapid metal breakdown and quick temperature adjustments. Additionally, a refractory lined flue extension reduces noise levels and moves heat and fumes above operator level for a more comfortable working environment.
