CAN-ENG's Steel Plant Heat Treatment Furnaces are workhorses for heat treating a wide variety of materials and applications. Whether annealing, bright annealing, normalizing, reheating, stress relieving or quench and tempering, CAN-ENG custom engineered Steel Plant Furnace Systems deliver consistent quality and reliable performance for tube, bar and plate, forgings, fabrications and castings.Common media for quenching include special-purpose polymers, forced air convection, freshwater, saltwater, and oil. Water is an effective medium when the goal is to have the steel to reach maximum hardness. However, using water can lead to metal cracking or becoming distorted. If extreme hardness isn't necessary, mineral oil, whale oil, or ...

In forging process, quenching temperature is the critical factor on affecting products solidity and wear resistance. In order to guarantee products quality and improve work efficiency, it is very essential to monitor and control quenching temperature automatically. To keep quenching temperature in normal range, a novel automatic supervisory control system based on SCM minimum system was designed.The free torsional stiffness of hot-rolled section steel is higher than that of cold-rolled section steel, so the torsional resistance of hot-rolled section steel is better than that of cold-rolled section steel.
