Use of quenching oil for quenching furnace

Use of quenching oil for quenching furnace

The allowable and recommended operating temperature range is specified for all quenching furnace quenching oils. Within the specified range, the operating temperature can be determined according to the actual situation. Properly increasing the oil temperature can reduce the viscosity of the oil, so that the quenching and cooling capacity of the oil is slightly improved. If the oil temperature is too high, the cooling capacity will be reduced due to the reduced temperature difference with the workpiece.

High oil temperature will lead to rapid oxidative deterioration of oil; low oil temperature will lead to slow oxidative deterioration of oil. The circulating cooling system of the quenching oil should be kept in good condition, so that the temperature of the quenching oil can be stabilized in the required range. At the same time, in order to prolong the service life of the oil, the excessively high oil temperature should be used less.

According to different working conditions, different burners are used. For example, adjustable flame burners, flat flame burners, high-speed nozzles, self-preheating burners, low nitrogen oxide burners, and recently developed regenerative burners, provide a variety of advanced to adapt to the use of gas and diesel burner. The correct use of advanced burners can generally save energy by more than 5%. The flat flame burner is suitable for use in heating furnaces, and the high-speed burner is suitable for all kinds of heat treatment furnaces and heating furnaces. The self-preheating burner is a combustion device that combines a burner, a heat exchanger, and a smoke exhaust device. Suitable for various industrial furnaces such as heating, melting, heat treatment, etc.

According to the type of fuel, it is also effective to select an energy-saving combustion device with good performance and matching fans, oil pumps, valves, and thermal testing and automatic control systems to ensure good combustion conditions and control and adjustment functions. Energy-saving measures.
