End quenching machine/End quenching testing machine/End quenching test

DZ—2、 4. The 6, 9, and 12 end quenching test benches meet 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.

DZ-2、 4. The 6, 9, and 12 end quenching test benches have the advantages of high technological content, good stability, and usability; The 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.
