Furnaces improve melt quality-decrease gas consumption. (Technology in Action).USER--Mahoney Foundry, a family-owned foundry in Kendallville, IN, makes aluminum castings for commercial lighting, electrical contacts Noun 1. electrical contact - contact that allows current to pass from one conductor to another tangency, contact - (electronics) a junction where things (as two electrical conductors) touch or are in physical contact; "they forget to solder the contacts" , electric motors, valving and automotive brake components. OPERATION--Mahoney Foundry melts with nine 1,000 lb. capacity gas-fired Morgan clip-out crucible crucible, vessel in which a substance is heated to a high temperature, as for fusing or calcining. The necessary properties of a crucible are that it maintain its mechanical strength and rigidity at high temperatures and that it not react in an undesirable way with furnaces. These supply metal to three Hunter mold handling systems, one Squeezer, two Rotolifts, a Nobake/Airset and three Hall Tilt Pours. It casts 110,00 lbs. per year. PROBLEMS--After installing a 4,500 lb. gas reverbatory furnace to provide capacity for two new Hunter mold lines, Mahoney Foundry found the reverb re·verb Informal n. 1. A reverberative effect produced in recorded music by electronic means. 2. A device used for producing this effect. intr. & tr.v. was expensive to operate, prone to oxide formation and did not provide alloy flexibility. Also, metal loss was high. SOLUTION--Mahoney Foundry replaced its reverb with four, gas-fired, 1,000 lb., Morgan crucible furnaces. It reported that gas consumption dropped 39 percent, a savings of $42,000 per year. More importantly, metal quality increased significantly. Also, metal loss dropped from about 11% with the reverb to less than 2% with the Morgan furnaces. BENEFITS--Another $3,600 per year was saved by Mahoney Foundry simply because the four Morgan furnaces needed just 1 lb. of wall cleaning flux per day while the reverb had required 10 lbs, of bath flux and 4 lbs. of wall cleaning flux per day.
