2010年我公司承接APL公司一批船用拉伸主液压缸,其缸体如图1所示,材质为EH36锻件。因该液压缸用于海上油轮,且该液压缸的SR300mm2球面与拉伸主液压缸支座之间有相对支撑运动。故需在SR300mm2球面上堆焊5mm厚的Inconel625耐腐蚀、耐磨层,以增强其耐腐蚀、耐磨性。
In 2010 our company to undertake a number of APL Marine tensile main hydraulic cylinder, the cylinder shown in Figure 1, made of EH36 forgings. Because the hydraulic cylinder is used for offshore oil tanker, and there is a relative supporting movement between the SR300 mm2 spherical surface of the hydraulic cylinder and the support of the main hydraulic cylinder. So it is necessary to surfacing 5mm thick Inconel625 corrosion-resistant and wear-resistant layer on SR300mm2 spherical surface to enhance its corrosion resistance and wear resistance.
