Batch Quenching Systems Water – Polymer - Oil Nutec Bickley manufactures and supplies quenching tanks. They are used for cooling the parts in water, oil or polymer after the heat treatment processes has ended. These are typically paired with a batch style furnace. In a box furnace operation the quench would be placed directly in front of the furnace and the system is comprised of and elevator platform with a roller conveyor. The same system can be paired with a roller hearth or pusher furnace for continuous operation. Large quench systems can be designed to be partnered with car bottom furnaces. In this arrangement the quenching systems are offset to allow the furnace car to travel and then unloaded by overhead crane or fork transfer mechanisms. They are manufactured in a wide variety of sizes and intended for intensive use. The size of a batch immersion quench tank depends on the dimensions of the workload, as well as the allowable temperature rise. The temperature rise permitted is dependent on whether the quenchant is oil, water, or polymer. Care should be taken in a batch operation to ensure that a sufficient amount of quenchant covers the top of the workload. The physical dimensions of the tank should be large enough to ensure full immersion of the quench load and fixtures, and, at the same time, should allow enough space for agitators and manipulators. When using hot quenching oils, it is necessary to make an allowance for thermal expansion of the oil, either by making provision for an overflow system, or by manual adjustment of the fluid level.
