Application of Intensive Quenching Technology for Steel Parts

IQ Technologies Inc (IQT) of Akron, Ohio, conducted extensive experimental and computational studies to demonstrate the benefits of intensive water quenching techniques for steel parts developed by Dr. Kobasko of the Ukraine. Two intensive quenching methods were applied: “direct convection cooling” (IQ-3 technique) and nucleate boiling (IQ-2 technique). Experiments and calculations were performed for a variety of steel products including automotive parts (coil springs, kingpins, torsion bars, bearing products, etc.), fasteners of different types including automotive bolts, tool products (punches, dies, die-casting machine parts, etc.). Experiments were conducted in 500-gallon experimental intensive quenching systems installed at Akron Steel Treating Co.'s facilities and in the 6000-gallon full-scale intensive quenching system installed at Summit Heat Treating Co.'s facilities.
