On-line concentration application of quenching liquid - MAYZUM on-line refractometer MAY-3001F

Quenching is to heat the metal parts to the phase change temperature above, after heat preservation in the quenching medium to obtain martensitic structure;   To achieve the purpose of improving or adjusting the hardness and wear resistance of parts.   In this process, the quenching medium (quenching liquid) is required to have good low deformation, low burning cracking, heat resistance, cleaning, degreasing, rust prevention, cooling, brightness, and a series of performance requirements.   The quenching process is widely used, including tools, measuring tools, molds, fasteners, nuts, hardware parts, bearings, springs, automobiles, tractors, diesel engines, cutting machine tools, pneumatic tools, drilling machinery, agricultural machinery tools, in addition, petroleum machinery, chemical machinery, textile machinery, aircraft and other parts are also in the use of quenching process.

Before adding a new quenching agent, clean the quenching tank first, calculate the amount of quenching liquid stock required according to the volume of quenching liquid tank and the recommended concentration of quenching liquid, and then inject an appropriate volume of clean water into the clean plastic bucket, and then use a stirring rod to slowly stir the water in the plastic bucket to form a vortex and then slowly inject the quenching liquid.   Then pour the prepared quenching liquid into the quenching liquid tank, and finally turn on the machine tool circulation quenching liquid after the liquid level in the quenching liquid tank reaches the required level.

In actual use, in order to obtain a quenching cooling rate similar to that of oil, the concentration range is generally 8~20%, about 15~20%

Within the scope of use, it can be seen that the role of online refractometer in industrial production is still quite obvious。

In this process, the online refractometer is used to help adjust the concentration of the solution, prepare a quenching liquid with cooling performance that can meet the requirements, and the workpiece is hardened evenly, which can significantly reduce the tendency of deformation and cracking, help improve the quality of the workpiece, improve the working environment and working conditions, and bring energy saving, environmental protection, technical and economic benefits to the factory.

At the same time, the online refractometer can realize the concentration control of the quenching liquid, can continuously monitor the concentration of the quenching liquid, display the concentration value in real time, and the data can be transmitted to the remote monitoring equipment, which is convenient for automatic control and ensure the quality of the process.

MAYZUM online refraction meter MAY-3001F, directly installed in the production/discharge pipeline, adopts the principle of refraction method, real-time monitoring of liquid Brix (soluble solid) in the pipeline through the online sensor, in order to further improve the production efficiency, real-time monitoring and automatic adjustment. By monitoring the change of concentration, the automatic system can automatically adjust the production parameters according to the set parameters, thus optimizing the production process. MAYZUM online refractoscope has been widely used in food, biochemistry, pharmaceutical, sugar, beverage, chemical and other industries to achieve multi-process concentration monitoring for the stock solution, extraction, mixing, cleaning, etc., effectively ensuring the unity of product quality. And comprehensively improve the level of enterprise automated production!
