Quenching is a small diameter seamless steel tube heated to above the critical temperature, heat preservation for a period of time, then quickly into the quenching medium, the temperature plummeted, rapid cooling, at the rate of greater than the critical cooling rate, which is mainly composed of martensite and unbalanced heat treatment method of the organization.

Seamless steel quenching technology in the metallurgical industry in the water hardening equipment is widely used in the heat treatment of seamless tube production line, through the seamless tube for water hardening, improved hardness and wear resistance of steel. Quenching and tempering with different temperatures can significantly improve the toughness and fatigue strength of steel, to obtain better mechanical properties of the steel. Quenching process water hardening equipment previously hardening furnace is heated by the feeding device into the pipe directly into the quench tank filled with cooling water to cool after a certain time set aside by the discharging device. Such hardening process is likely to cause uneven cooling pipe, bending, 에그벳계열 cracking and other defects, affect the performance of the steel pip

/>The new seamless tube water hardening equipment, using the advanced quenching process, and a lot of structural transformation, technological innovation, effectively improve the accuracy and mechanical properties of steel, greatly reducing the cracking, bending, oval and other defects. By analyzing the water quenching equipment works, quenching process, structural characteristics, indicating that the device with various other domestic water hardening equipment in the mechanical structure, the quenching effect, precision steel after quenching, mechanical properties and so on. At present main slotted in the inland waters quench hardening of seamless steel tube technology and the web of quenching process. The easiest way to slot in the inland waters and quenching process is immersion; But to make the top and bottom steel pipe cooling spee

/>Digestion and absorption of water hardening equipment in the domestic and foreign advanced hardening technology, on this basis, has conducted a number of technical innovations, effectively improve the cooling uniformity and hardenability, reducing the quench cracking, bending, oval and other defects, which is set of hydraulic, mechanical, electrical, computer control in one of the new water hardening equipment. Practice has proved that this device has a water quench hardening uniform cooling speed steel after high precision, high hardness, wear resistance , and many other advantage
