Selection of water-based quenching oil for heat treatment of Lapped Joint Flanges

The quenching process in the heat treatment of Lapped Joint Flanges is divided into induction quenching and immersion quenching. In both ways, water-based quenching oil will affect the cooling speed of Lapped Joint Flanges after heat treatment. Therefore, the selection of appropriate water-based quenching machine is particularly important for the heat treatment of Lapped Joint Flanges. It is necessary to study the physical properties of each water-based quenching oil and the influence of its concentration ratio on the cooling rate of Lapped Joint Flanges after heat treatment. In addition, the purity and concentration shall be maintained. During the heat treatment of the Lapped Joint Flanges, its concentration shall be tested regularly to ensure the heat dissipation capacity. Check the pH value to ensure the corrosion resistance of the Lapped Joint Flanges after heat treatment. Check the pollution (hydraulic oil, etc.) that may adversely affect the cooling of Lapped Joint Flanges after heat treatment and may affect its metallurgical properties. Check for microorganisms that may contaminate the water-based quenchant. These microorganisms will produce unpleasant odor in the quenching tank and working environment. Affect the safety and working environment of workers in the Lapped Joint Flanges heat treatment workshop. Depending on the situation, if necessary, the heat treatment of Lapped Joint Flanges shall use biological stable water-based quenchant. Moreover, as the supplier of Lapped Joint Flanges, the operation in heat treatment is extremely important. Shanxi Haokun flanges Group Co., Ltd. will actively implement the social responsibility as Lapped Joint Flanges and take the initiative to maintain in advance to ensure that the chemical properties of Lapped Joint Flanges purchased by customers meet the standards and requirements. To provide customers with efficient and high-quality Lapped Joint Flanges products.
