    摘要： The invention comprises a double loop channel type induction furnace of which the floor has a base on a first side of its hearth and a ramp which rises from the base to terminate in a plateau above the passages at a location distal from the first side. The ramp and plateau extends at least partly between opposing end walls of the furnace, and the plateau includes a trench which extends at least partly between opposing ends of the plateau. The trench is in fluid communication with the passages and the bottom of the trench is located in a plane higher than the plane in which the furnace floor is located. The base of the furnace floor is in fluid communication with the central passage by means of a floor passage that extends from the base of the floor to the central passage through the ramp below the trench.

    摘要： A method of restoring the electrical efficiency of channel and pressure pour furnaces includes plunging a fluxing material with a specially designed plunging lance. The plunging lance chamber containing the fluxing material is 24 to 32 inches in length, 3 inches in diameter and has a capacity to hold 5 to 7.5 pounds of flux briquettes. The plunging chamber has holes drilled along the length of the body. The fluxing material contains by weight from 8.0 to 28.7% CaCO3 (calcium carbonate or limestone), from 0 to 18.5% MgCO3 (magnesium carbonate), from 3.6 to 18.0% Al2O3 (alumina) from 1.4 to 7.1% SiO2 (silica), in the form of a complex aluminosilicate, and from 19.4 to 46.4% Na2O (sodium oxide), in the form of soda ash (sodium carbonate). The total level of sodium ranges from 23 to 26% and up to 10% sodium fluoride or sodium chloride may be substituted for soda ash.

    摘要： A high frequency core and coil electric metal melting furnace is shown. This furnace has a lined channel in its inductor for carrying the molten metal. The invention provides an improved inductor for a core and coil furnace that is not subject to leakage of the molten metal from the channel into the rammed refractory support bed for the channel which leakage otherwise shortens the lift of the furnace. Also a method of lining the channel in the inductor for carrying the molten metal which forms the core is disclosed.
