The corresponding model of QPQ liquid salt bath nitriding furnace is RNY series well type liquid nitriding furnace, also known as salt bath nitriding furnace, well type liquid nitriding furnace, liquid nitriding furnace, salt bath nitriding furnace, QPQ nitriding furnace, well type liquid compound nitriding furnace, liquid salt bath nitriding furnace, salt bath liquid nitriding furnace, etc. QPQ liquid nitriding furnace is a kind of liquid carbonitriding process, commonly known as soft nitriding. It is a process that infiltrates the materials containing carbon and nitrogen elements into the workpiece at the same time. It is mainly used for liquid nitriding, nitriding and carbonitriding of various workpieces such as molds, mechanical accessories and other workpieces in situations requiring high wear resistance, high corrosion resistance, fatigue resistance and micro deformation. Such as: automobile, motorcycle, locomotive, engineering machinery, agricultural machinery, light industrial machinery, textile machinery, machine tools, instruments, instruments, firearms, gears, tooling and other industries.

 

QPQ liquid salt bath nitriding furnace is composed of furnace shell, furnace cover, heat insulation furnace lining, heating elements, heat-resistant steel furnace tank, furnace cover startup (hydraulic or manual) device, etc. The temperature control of nitriding furnace adopts the Artificial Intelligence PID automatic temperature controller, which has the function of self identification and self diagnosis, and has the upper limit alarm, which greatly improves the uniformity of furnace temperature.

 

The equipment of liquid nitriding furnace has the advantages of simple structure, low one-time investment, stable performance, low failure rate, simple and easy operation process, less accessories and small floor area. The deficiency is that the nitriding layer is shallow, and the workpiece should be cleaned after being discharged from the furnace.

 

QPQ salt bath composite heat treatment technology can not only make the workpiece hardly deformed, but also greatly improve the wear resistance and corrosion resistance of the metal surface. It is a new technology of strengthening and modifying the metal surface. This technology realizes the combination of nitriding process and oxidation process, the combination of nitride and oxide, the combination of wear resistance and corrosion resistance, and the combination of heat treatment technology and corrosion protection technology.

 

QPQ salt bath composite treatment is an advanced technology of metal surface strengthening and modification. The workpiece is treated in two kinds of molten salt solutions with different properties successively, so that a variety of elements penetrate into the metal surface at the same time, forming a composite infiltration layer composed of several compounds, so that the metal surface is strengthened and modified, and the wear resistance, corrosion resistance and fatigue resistance are greatly improved at the same time.
