this เตาหลอมอลูมิเนียม( gas fired melting furnace) is designed to serve various industrial purposes. it consist of various elements like fe, al, cr, which are supported by numerous other equipments for better heat distribution of heat and longer lifetime of the element. these aluminum melting furnace are capable of any type of alloys. these furnaces are well insulated that allows a better heat and energy distribution, which improves the crucible life expectancy. the aluminum furnace are available in various size and capacities.
common features of the เตาหลอมอลูมิเนียม( gas fired melting furnace) :
based on the types of heating used by aluminum furnace, they are classified into two types- electric aluminum furnace and gas fired furnace.
electrical aluminum furnace:
the left an electrical aluminum melting furnace consist of a vessel for supporting molten aluminum and a roof and upper wall structure cooperating with side walls of the vessel to define a heating chamber above the molten aluminum. large number of unshielded resistance heating elements are supported by the roof and upper wall structure above the molten aluminum.
there is a charging well which is submerged and from where molten aluminum has access to a charging well to which unmelted aluminum is periodically charged without danger of splashing molten aluminum upon the heating elements.
the chamber from where heat is conducted is heating chamber. heat conducted through the body of molten aluminum residing in the vessel is utilized to melt in the charging well the aluminum charged thereto.
the melted aluminum in the charging well flows through the heating chamber and through a submerged opening to a hot metal well from which hot metal may be withdrawn by any of numerous techniques.
