End Quench Test Apparatus ( Model : MEQ-25 )

• This apparatus is useful for determining the hardenability of steels by End Quench Test.
• The test consists of heating a standard size specimen to a given temperature for a specific period of time, followed   by a water quenching of one end under specified conditions and measuring the hardness at various points from   quenched end along the length of test piece.
• This apparatus conforms to IS : 3848 – 1981 and ASTM-A255.

Working Principle
• After heating, the test specimen is kept on the specimen support, where it is automatically centered with respect to   water jet.
• The quick action valve starts impinging the water jet on the specimen end instantly.
• The elaborate arrangement of pump, tank, pipe etc, enables to obtain desired correct water head for the nozzle.
• The electrical controls and safety devices for pump and motor are provided and the entire apparatus is totally   enclosed.
