Quartet Thermal Engineering Pvt. Ltd. Manufactures Continuous Hardening Washing and Tempering Plants. Quartet Thermal Engineering Pvt. Ltd. Supplies wide range of Heat Treatment Plants and Furnaces. The Continuous Hardening Washing and Tempering Plants for Large Parts require hardening and tempering. This plant is designed to achieve the whole process within a protective atmosphere. These quality automatic continuous hardening & tempering plants are continuously quenched, a few pieces at a time instead of in a batch at periodic intervals so as to obtain consistent quality. Majority of total tonnage of heat treated components also do not require fixturing and can tumble into quench tank. Continuous conversed heating and quenching system is also ideal plant for all above mentioned components in terms of quality, operating costs and capital costs involved.
