DZH-6 (9) End Quenching Testing Machine

Brief introduction
The DZH-6 (9) end quenching test bench meets the requirements of GB/T225-2006 (End test method for steel hardenability) standard, as well as relevant standards such as American standard ASTM225-02, German standard DIN50191, Japanese standard JIS G0561-1998, and international standard ISO642. Suitable for end face quenching tests of high-quality carbon structural steel, alloy structural steel, spring steel, tool steel, bearing steel, low hardenability structural steel and other steel grades. The DZH-6 (9) end quenching test bench has the advantages of high technological content, good stability, and usability; Advanced digital quenching time control system and temperature control system are adopted, which can automatically start automatic temperature control (constant temperature) automatic water spraying quenching end the entire working cycle. The overall design layout is reasonable, the structure is compact, easy to operate, and convenient for maintenance and repair.
2、 Product Features
1. The test bench consists of a frame, high and low water tanks, an automatic water circulation system for water pumps, a spray time setting system, an automatic quick opening device for nozzles, a water temperature regulation control system, and other components
The control of the water spray start function adopts two control methods: high sensitivity (photoelectric induction) automatic and manual.
3. High precision digital time relays are used for time control, and the sprinkler pipe automatically shuts off when the set time is reached.
4. The water temperature control adopts an imported compressor refrigeration and heating system for heating. The water temperature control accuracy is high, and the water tank is equipped with temperature control instruments.
5. The advantages of stable alignment between the inner hole of the sample holder and the nozzle, and easy adjustment.
6. The water spraying station can control the work separately or simultaneously. Flexible and convenient operation.
