Shandong Defu supply heat quenching liquid cooling plate heat exchanger! Quenching is a metal workpiece is heated to a suitable temperature and for a time, then immersed in quenching medium fast cooled metal heat treatment process. Commonly used quenching medium have saline, water, mineral rock, such as air. Quenching process in modern machinery manufacturing industry has been widely used. Important mechanical parts, especially in the automotive, aircraft, rockets, applied almost hardened steel handle. Including heating, insulation; cooling three phases. Heat treatment and quenching liquid cooling system, is subordinate to the quenching tank auxiliary equipment. Its main role is: to quench tank overheating quenching liquid, using the method of heat exchange and cooling to meet the required temperature (such as quenching oil control in 30 ~ 70 ℃, saline solution control to below 45 ℃, etc.); also continue to supply sufficient quantities of quenching tank, stable performance liquid quenching, quenching tank is working properly ensure safe operation. Hardening of the workpiece quality improved production efficiency, energy saving is the key. .
