Consistency of quality is better obtained when components are continuously quenched, a few pieces at a time instead of in a batch at periodic intervals. Of the total tonnage of heat treated components the majority do not require fixturing and can tumble into a quench tank. The ideal plant for all such components in terms of quality, capital cost as well as operating cost is a continuous conveyorised heating and quenching system. Components spend less time at temperature and consume less energy compared to batch furnaces. Continuous quenching, a few components at a time, ensure a high degree of quality consistency in terms of hardness, case depth and physical properties. Such plants with conveyorised auxiliary equipment for loading, washing and tempering are normally fully automated.
