Thermcraft Inc. has been awarded a U.S. patent for its LQF technology. The liquid quench fluidization (LQF) process was engineered and developed as a green technology. A liquid quench technology used in the heat treatments of medium- and high-carbon wire products, LQF is a lead-free, environmentally friendly process replacing molten lead, salt or fluidization media. The process is precisely adjustable for each steel grade TTT-curve and will result in a higher concentration of the desirable pearlitic structure. Thermcraft has designed and built successful pilot-scale production units, and full-scale production units will be built for different product applications in the wire industry.
